BEA TUXEDO System ASCII configuration file
A binary configuration file, called the TUXCONFIG file, contains information used by tmboot(1) to start the servers and initialize the bulletin board of a BEA TUXEDO system bulletin board instantiation in an orderly sequence. The binary TUXCONFIG file cannot be created directly (although an existing TUXCONFIG file can be dynamically modified through tmconfig(1)). Initially, a UBBCONFIG file of the format described on this reference page must be created. That file is parsed and loaded into the TUXCONFIG file using tmloadcf(1). tmadmin(1) uses the configuration file (or a copy of it) in its monitoring activity. tmshutdown(1) references the configuration file for information needed to shut the application down.
A server is a process that accepts requests and sends replies for clients and other servers. A client originates requests and gets replies.
A resource manager is an interface and associated software providing access to a collection of information and/or processes. An example of a resource manager is a database management system; a resource manager instance is a particular instantiation of a database controlled by a DBMS. A distributed transaction is a transaction that spans multiple resource manager instances, is started with tpbegin, and ended with tpcommit or tpabort.
A server group is a resource manager instance and the collection of servers and/or services providing access to that resource manager instance on a particular machine. The XA interface associated with the group is used for transaction management. If a server does not access a resource manager instance or does not access it as part of a distributed transaction, it must be in a server group with a null XA interface. Similarly, clients run in a special client group that does not have to be specified in the GROUPS section. The client group is not associated with a resource manager.
A remote domain is defined to be an environment for which this configuration's BEA TUXEDO system bulletin board is not available. Remote domains are not specified in the UBBCONFIG file, but rather through host-specific environment variables that are specified in host-specific reference pages.
The format of a UBBCONFIG file is as follows:
The file is made up of up to none specification sections. Lines beginning with an asterisk (*) indicate the beginning of a specification section. Each such line contains the name of the section immediately following the *. Allowable section names are: RESOURCES, MACHINES, GROUPS, NETGROUPS, NETWORK, SERVERS, SERVICES, INTERFACES, and ROUTING. The RESOURCES and MACHINES sections must be the first two sections in that order; the GROUPS section must be ahead of SERVERS, SERVICES, and ROUTING. The NETGROUPS section must ber ahead of the NETWORK section.
Parameters (except in the RESOURCES section) are generally specified by: KEYWORD = value. This sets KEYWORD to value. Valid keywords are described within each section. KEYWORDs are reserved; they can not be used as values.
Lines beginning with the reserved word, DEFAULT:, contain parameter specifications that apply to any lines that follow them in the section in which they appear. Default specifications can be used in all sections other than the RESOURCES section. They can appear more than once in the same section. The format for these lines is:
DEFAULT:[optionalKEYWORD=valuepairs]
The values set on this line remain in effect until reset by another DEFAULT: line, or until the end of the section is reached. These values can also be overridden on non-DEFAULT: lines by placing the optional parameter setting on the line. If on a non-DEFAULT: line, the parameter setting is valid for that line only; lines that follow revert to the default setting. If DEFAULT: appears on a line by itself, all previously set defaults are cleared and their values revert to the system defaults.
If a value is numeric, standard C notation is used to denote the base (that is, 0x prefix for base 16 (hexadecimal), 0 prefix for base 8 (octal), and no prefix for base 10 (decimal)). The range of acceptable values for a numeric parameter is given under the description of that parameter.
If a value is an identifier, standard C rules are used. An identifier must start with an alphabetic character or underscore and contain only alphanumeric characters or underscores. The maximum allowable length of an identifier is 30 (not including the terminating null). An identifier cannot be the same as a KEYWORD.
A value that is neither an integer number or an identifier must be enclosed in double quotes. This value is called a string. The maximum allowable length of a string is 78 (not including the terminating null). Exceptions to this are the CLOPT, BUFTYPE, OPENINFO, and CLOSEINFO parameters, which can be 256 characters in length, and the RANGES parameter, which can be 2048 characters in length (except in Domain, where it can be no more than 1024 characters). In the RANGES parameter of the ROUTING section, certain special characters can be escaped inside a string using a backslash.
"\\" translates to a single backslash.
"\"" translates to a double quote.
"\n" translates to a newline.
"\t" translates to a tab.
"\f" translates to a formfeed.
"\O+" translates to a character whose octal value is O+
where O+ is one, two, or three octal characters. "\0" translates to an embedded null character. "\xH+" or "\XH+" translates to a character whose hexadecimal value is H+ where H+ is one or more hexadecimal characters. "\y" (where 'y' is any character other than one of the previously mentioned characters) translates to 'y'; this produces a warning.
Some values are required to be an identifier. Other values that can be either an identifier or a string are indicated as a string_value. The maximum allowable length of a string_value is 78 characters if it is a string (not including the terminating null) and 30 characters if it is an identifier.
"#" (pound sign) introduces a comment. A newline ends a comment.
An identifier or a numeric constant must always be followed by white space (space, tab, or newline) or a punctuation character (pound sign, equals sign, asterisk, colon, comma, backslash, or period).
Blank lines and comments are ignored.
Comments can be freely attached to the end of any line.
Lines are continued by placing at least one tab after the newline. Comments can not be continued.
This section provides for user specification of the system-wide resources, such as the number of servers, and services which can exist within a service area. Lines in the RESOURCES section are of the form: KEYWORD value where KEYWORD is the name of the parameter, and value its associated value. Valid KEYWORDs are as follows:
IPCKEY numeric_value
IPCKEY must be greater than 32,768 and less than 262,143. This parameter is required.
MASTER string_value1[,string_value2]
TUXCONFIG is found. Also, if the application is being run in MP mode, MASTER names the machine on which the DBBL should be run. string_value2 names an alternate LMID location used during process relocation and booting. If the primary location is not available, the DBBL is booted at the alternate location and the alternate TUXCONFIG file found there is used. Both LMID values must name machines found in the MACHINES section and must be less than or equal to 30 characters in length. This parameter is required (even in SHM mode).
In an application that supports multiple release levels of the BEA TUXEDO system on different machines, MASTER and BACKUP must always have a release with a number greater than or equal to all other machines in the application. This rule is not enforced during a "Hot Upgrade."
DOMAINID string_value1
DOMAINID is a character string, it may contain a maximum of 30 characters (including the trailing null). If the value of DOMAINID is a string of hexadecimal digits, it may contain a maximum of 30 octets. If DOMAINID is specified, its value is included, as a parameter (-C dom=domainid), in any command output that reports on the processes associated with a particular domain, such as the output of the ps command. This comment is useful for an administrator managing multiple domains, who may have some difficulty, without this comment, in interpreting a single output stream that refers to several domains.
UID numeric_value
tmloadcf(1). The RESOURCES value for this parameter can be overridden in the MACHINES section on a per-processor basis.
GID numeric_value
GID is not specified, the effective group id of the user executing tmloadcf(1) is used. The RESOURCES value for this parameter can be overridden in the MACHINES section on a per-processor basis.
PERM numeric_value
RESOURCES value for this parameter can be overridden in the MACHINES section on a per-processor basis.
MAXACCESSERS numeric_value
tmadmin, need not be accounted for in this figure. This value must be greater than 0 and less than 32,768. If not specified, the default is 50. The RESOURCES value for this parameter can be overridden in the MACHINES section on a per-processor basis.
MAXSERVERS numeric_value
MAXSERVICES numeric_value
MAXGROUPS numeric_value
MAXNETGROUPS numeric_value
NETWORK section of the TUXCONFIGfile. This value must be greater than or equal to 1 and less than 8192. If not specified, the default is 8.
MAXMACHINES numeric_value
MAXQUEUES numeric_value
MAXSERVERS. Interoperability with releases prior to 5.0 requires that this value be equal to the configured value for MAXSERVERS.
MAXACLGROUPS numeric_value
TA_MAXACLGROUPS - 1. This value must be greater than or equal to 1 and less than or equal to 16K. If not specified, the default is 16K.
MODEL { SHM | MP }
SHM specifies a single machine configuration; only one machine may be specified in the MACHINES section. MP specifies a multi-machine configuration; MP must be specified if a networked application is being defined. Note: to change value without relinking, servers must be built to support the models needed (see buildserver(1)).
LDBAL { Y | N }
LDBAL is not specified, the default is Y. It is recommended that if each service maps to one and only one queue, then LDBAL should be set to N, since load balancing is automatic.
CMTRET { COMPLETE | LOGGED }
TP_COMMIT_CONTROL characteristic for all client and server processes in a System/T application. If value is LOGGED, then the TP_COMMIT_CONTROL characteristic is initialized to TP_CMT_LOGGED; otherwise, it is initialized to TP_CMT_COMPLETE. If CMTRET is not specified, the default is COMPLETE. See the description of the BEA TUXEDO system ATMI function, tpscmt, for details on the setting of this characteristic.
OPTIONS identifier[,identifier . . . ]
LAN indicates that this is a networked application. The identifier MIGRATE indicates that server group migration can be done. If MIGRATE is specified, LAN should also be specified, (except for the case where the configuration runs on a single multiprocessor computer). This parameter is optional and the default is no options.
SYSTEM_ACCESS identifier[,identifier]
FASTPATH or PROTECTED. FASTPATH specifies that the internal tables should be accessible by the libraries via shared memory for fast access. PROTECTED specifies that while the internal tables are accessible by BEA TUXEDO system libraries via shared memory, the shared memory for these tables is not accessible outside of the BEA TUXEDO system libraries. NO_OVERRIDE can be specified (either alone or in conjunction with FASTPATH or PROTECTED) to indicate that the mode selected cannot be overridden by an application process. If SYSTEM_ACCESS is not specified, the default mode is FASTPATH.
SECURITY string_value1
NONE, APP_PW, USER_AUTH, ACL, or MANDATORY_ACL. This parameter defaults to NONE. The value APP_PW indicates that application password security is to be enforced (clients must provide the application password during initialization). Setting APP_PW causes tmloadcf to prompt for an application password. The value USER_AUTH is similar to APP_PW but, in addition, indicates that per-user authentication will be done during client initialization. The value ACL is similar to USER_AUTH but, in addition, indicates that access control checks will be done on service names, queue names, and event names. If an associated ACL is not found for a name, it is assumed that permission is granted. The value MANDATORY_ACL is similar to ACL but permission is denied if an associated ACL is not found for the name.
AUTHSVC string_value
SECURITY identifier be set to USER_AUTH, ACL, or MANDATORY_ACL. (For upward compatibility, setting both SECURITY APP_PW and AUTHSVC implies SECURITY USER_AUTH.) The parameter value must be 15 characters or less in length. For SECURITY level USER_AUTH, the default service name, if not specified, is AUTHSVC. For SECURITY level ACL or MANDATORY_ACL, the service name must be ..AUTHSVC. (This will be silently enforced if the administrator tries to set it to anything else.)
MAXGTT numeric_value
RESOURCES value for this parameter can be overridden in the MACHINES section on a per-processor basis.
MAXCONV numeric_value
SERVERS section and 1 otherwise. The RESOURCES value for this parameter can be overridden in the MACHINES section on a per-processor basis. The maximum number of simultaneous conversations per server is 64.
MAXBUFTYPE numeric_value
MAXBUFSTYPE numeric_value
MAXDRT numeric_value
ROUTING section entries.
MAXRFT numeric_value
ROUTING section entries.
MAXRTDATA numeric_value
ROUTING section entries.
SCANUNIT numeric_value
tpbegin(3c) and the blocking timeout value specified with the BLOCKTIME parameter. The SANITYSCAN, BBLQUERY, DBBLWAIT, and BLOCKTIME parameters are multipliers of this unit for other timed operations within the system. SCANUNIT must be a multiple of 5 greater than 0 and less than or equal to 60 seconds. The default is 10 seconds.
SANITYSCAN numeric_value
SCANUNIT between sanity checks of the system. The value SCANUNIT must be greater than 0. If this parameter is not specified, the defaultdefault is set so that (SCANUNIT * SANITYSCAN) is approximately 120 seconds. Sanity checks include checking servers as well as the bulletin board data structure itself. Each BBL checks that all servers on its machine are viable; that is, the server hasn't terminated abnormally and is not looping. Processes deemed not viable are either cleaned up, or restarted depending on the options with which they were started. Following that, the BBL sends a message (without reply) to the DBBL to indicate it is okay.
DBBLWAIT numeric_value
SCANUNIT for the maximum amount of wall time a DBBL should wait for replies from all its BBLs before timing out. Every time the DBBL forwards a request to its BBLs, it waits for all of them to reply with a positive acknowledgment before replying to the requester. This option can be used for noticing dead or insane BBLs in a timely manner. The value of DBBLWAIT must be greater than 0. If this parameter is not specified, the default is set so that (SCANUNIT * DBBLWAIT) is the greater of SCANUNIT or 20 seconds.
BBLQUERY numeric_value
SCANUNIT between status checks by the DBBL of all BBLs. The DBBL checks to ensure that all BBLs have reported in within the BBLQUERY cycle. If a BBL has not been heard from, the DBBL sends a message to that BBL asking for status. If no reply is received, the BBL is partitioned. The value of BBLQUERY must be greater than 0. If this parameter is not specified, the default is set so that (SCANUNIT * BBLQUERY) is approximately 300 seconds.
BLOCKTIME numeric_value
SCANUNIT after which a blocking call (for example, receiving a reply) times out. The value of BLOCKTIME must be greater than 0. If this parameter is not specified, the default is set so that (SCANUNIT * BLOCKTIME) is approximately 60 seconds.
NOTIFY { DIPIN | SIGNAL | IGNORE }
tpinit(3c) flag value. Note that once unsolicited messages are detected, they are made available to the application through the application defined unsolicited message handling routine identified via the tpsetunsol function ( tpnotify(3c)). The value DIPIN specifies that dip-in-based notification detection should be used. This means that the system will only detect notification messages on behalf of a client process while within ATMI calls. The point of detection within any particular ATMI call is not defined by the system and dip-in detection will not interrupt blocking system calls. DIPIN is the default notification detection method. The value SIGNAL specifies that signal-based notification detection should be used. This means that the system sends a signal to the target client process after the notification message has been made available. The system installs a signal catching routine on behalf of clients selecting this method of notification. All signaling of client processes is done by administrative system processes and not by application processes. Therefore, only clients running with the same UNIX System user identifier can be notified using the SIGNAL method. The value IGNORE specifies that by default, notification messages are to be ignored by application clients. This would be appropriate in applications where only clients that request notification at tpinit time should receive unsolicited messages.
USIGNAL { SIGUSR1 | SIGUSR2 }
SIGNAL-based notification is used. The legal values for this parameter are SIGUSR1 and SIGUSR2. SIGUSR2 is the default for this parameter. USIGNAL may be specified even if SIGNAL-based notification is not selected with the NOTIFY parameter, because callers of tpinit may choose signal-based notification.
The MACHINES section specifies the logical names for physical machines for the configuration. It also specifies parameters specific to a given machine. The MACHINES section must contain an entry for each physical processor used by the application. Entries have the form:
ADDRESSrequired parameters[optional parameters]
where ADDRESS is the physical name of a processor, for example, the value produced by the UNIX system uname -n command. The length of the entire ADDRESS must be 30 characters or less. If the name is not an identifier, it must be enclosed in double quotes. If the LAN option is not specified, only one machine name can appear in this section. One of the required KEYWORDs is LMID, which is the logical machine string_value assigned to the physical machine. An LMID string_value must be unique within the MACHINES section of the configuration file.
LMID = string_value
string_value is to be used in other sections as the symbolic name for ADDRESS. This name cannot contain a comma, and must be 30 characters or less. This parameter is required. There must be an LMID line for every machine used in a configuration.
These parameters are required:
TUXCONFIG = string_value
TUXCONFIG file is found on this machine. The maximum string value length is 64 characters. The administrator need only maintain one TUXCONFIG file, namely the one that is pointed to by the TUXCONFIG environment variable on the MASTER machine. Copies on other machines of this master TUXCONFIG file are synchronized with the MASTER machine automatically when the system is booted. This parameter must be specified for each machine. If TUXOFFSET is specified, then the BEA TUXEDO file system starts at that number of blocks from the beginning of the TUXCONFIG device (see TUXOFFSET below). See ENVFILE in the MACHINES section for a discussion of how this value is used in the environment.
TUXDIR = string_value
TUXDIR should not be on a remote file system. If the machines of a multiprocessor application have different BEA TUXEDO system releases installed, check the discussion of "Interoperability" in the BEA TUXEDO Release Notes for the higher level release to make sure you will get the functionality you expect. See ENVFILE in the MACHINES section for a discussion of how this value is used in the environment.
APPDIR = string_value
SECURITY is set, each application must have its own distinct APPDIR. See ENVFILE in the MACHINES section for a discussion of how this value is used in the environment.
Optional parameters are:
UID = number
RESOURCES section.
GID = number
RESOURCES section.
PERM = number
RESOURCES section.
MAXACCESSERS = number
tmadmin, need not be accounted for in this figure, but all application servers and clients and TMS servers are counted. This value must be greater than 0 and less than 32,768. If not specified, the default is the value specified in the RESOURCES section.
MAXWSCLIENTS = number
MAXACCESSERS. The appropriate setting of this parameter helps to conserve IPC resources since workstation client access to the system is multiplexed through a BEA TUXEDO system-supplied surrogate, the workstation handler. This value must be greater than or equal to 0 and less than 32,768. The default is 0. It is an error to set this number greater than MAXACCESSERS.
MAXACLCACHE = number
SECURITY is set to ACL or MANDATORY_ACL. The appropriate setting of this parameter helps to conserve on shared memory resources and yet reduce the number of disk access to do ACL checking. This value must be greater than or equal to 10 and less than or equal to 30,000. The default is 100.
MAXCONV = number
RESOURCES section. The maximum number of simultaneous conversations per server is 64.
MAXPENDINGBYTES = number
number must be between 100,000 and MAXLONG.
MAXGTT = number
RESOURCES section.
TYPE = string_value
TYPE can be set to any string value that is 15 characters or less. If two machines have the same TYPE value, data encoding/decoding is bypassed when sending data between the machines. TYPE can be given any string value. It is used simply for comparison. The TYPE parameter should be used when the application involves a heterogeneous network of machines or when different compilers are used on the machines in the network. If not specified, the default is the null string, which matches any other entry that does not have a value specified.
CMPLIMIT = string_value1[,string_value2]
string_value1) and local processes (string_value2) respectively, at which automatic data compression will take place. Both values must be either a non-negative numeric value or the string MAXLONG. If not specified, the default for this parameter is MAXLONG,MAXLONG.
NETLOAD = numeric_value
SPINCOUNT = numeric_value
TMSPINCOUNT environment variable to be ignored. This varies from platform to platform. The default for this parameter is 0.
TLOGDEVICE = string_value
TLOG) for this machine. The TLOG is stored as a BEA TUXEDO system VTOC table on the device. If this parameter is not specified, then the machine is assumed to not have a TLOG. The maximum string value length is 64 characters.
TLOGOFFSET = offset
TLOGNAME = string_value
TLOG. If more than one TLOG exists on the same TLOGDEVICE, they must have unique names. TLOGNAME must be different from the name of any other table on the configuration where the TLOG table is created. It must be 30 characters or less.
TLOGSIZE = size
ULOGPFX = string_value
userlog(3c) message file on this machine. The value of ULOGPFX for a given machine is used to create the userlog(3c) message file for all servers, clients, and administrative processes executed on that machine. If this parameter is not specified, $APPDIR/ULOG is used. "mmddyy" (month, day, year) is appended to the prefix to get the actual log file name.
TUXOFFSET = offset
TUXCONFIG for this machine. The offset must be greater than or equal to 0 and less than the number of pages on the device. The default offset is 0. The value of TUXOFFSET, if non-zero, is placed in the environment of all servers booted on a machine. See ENVFILE in the MACHINES section for a discussion of how this value is used in the environment.
ENVFILE = string_value
Client programs process only the MACHINES ENVFILE during tpinit()
When booting servers, local servers inherit the environment of tmboot(1) and remote servers (not on the MASTER) inherit the environment of tlisten(1). TUXCONFIG, TUXDIR, and APPDIR are also put into the environment when a server is booted based on the information in the associated MACHINES entry. An attempt to reset these three variables to another value will not be allowed and will result in a warning. tmboot and tlisten process the machine ENVFILE before starting the server, allowing for the environment to indicate necessary pathnames for finding executable and dynamically loaded files. Once the server is running,as part of server initialization (before the application gets control in tpsvrinit), a server will read and export variables from both the machine and server ENVFILE files. If a variable is set in both the machine and server ENVFILE, the value in the server ENVFILE will override the value in the machine ENVFILE.
PATH and LD_LIBRARY_PATH are treated specially. Before a server is activated, the machine ENVFILE is scanned to find the first occurrence of a PATH or LD_LIBRARY_PATH variable; embedded environment variables within either PATH variable are not expanded. PATH and LD_LIBRARY_PATH are used to find pathnames for executable and dynamically loaded files. PATH will always be prefixed with
${APPDIR}:${TUXDIR}/bin:/bin:
if the value doesn't already begin with this string. This PATH will be used as a search path for servers that are specified with a simple or relative pathname. LD_LIBRARY_PATH will always be prefixed with
${APPDIR}:${TUXDIR}/lib:/lib:/usr/lib:
if the value doesn't already begin with this string. SHLIB_PATH is set on HPUX and LIBPATH is set on AIX instead of LD_LIBRARY_PATH.
This section provides information about server groups. This section must have at least one server group defined in it (which can be added via tmconfig(1) after the TUXCONFIG file has been created). A server group entry provides a logical name for a collection of servers and/or services on a machine. The logical name is used as the value of the SRVGRP parameter in the SERVERS section to identify a server as part of this group. SRVGRP is also used in the SERVICES section to identify a particular instance of a service with its occurrences in the group. Other GROUPS parameters associate this group with a specific resource manager instance (for example, the employee database). Lines within the GROUPS section have the form:
GROUPNAME required parameters [optional parameters]
where GROUPNAME specifies the logical name (string_value) of the group. The group name must be unique within all group names in the GROUPS section and LMID values in the MACHINES section and cannot contain an asterisk (*), comma, or colon. It must be 30 characters or less.
Required parameters are:
LMID = string_value1 [, string_value2]
MACHINES section (or the default in SHM mode). Each LMID value must be 30 characters or less. Up to two logical machine names can be specified. The second logical name, if given and if server group migration is enabled, indicates the machine to which the server group can be migrated.
GRPNO = number
GROUPS section.
Optional parameters are:
TMSNAME = string_value
a.out associated with this group. This parameter must be specified for any group entry whose servers will participate in distributed transactions (transactions across multiple resource managers--and possibly machines--that are started with tpbegin(3c), and ended with tpcommit(3c)/ tpabort(3c)). It specifies the file (string_value) to be executed by tmboot(1) when booting the server group. The value TMS is reserved to indicate use of the null XA interface. If a non-empty value other than TMS is specified, then a TLOGDEVICE must be specified for the machine(s) associated with the LMID value(s) for this entry. A unique server identifier is selected automatically for each TM server, and the servers will be restartable an unlimited number of times.
ENVFILE = string_value
${env} are expanded when the file is processed using variables already in the environment. (Forward referencing is not supported and if a value is not set, the variable is replaced with an empty string.) A backslash (\) may be used to escape the dollar sign and itself. All other shell quoting and escape mechanisms are ignored and the expanded value is placed in the environment.
The ENVFILE is read after the MACHINES section ENVFILE (if one exists) and before the SERVERS section ENVFILE (if one is specified).
TMSCOUNT = number
TMSNAME is specified. This parameter is optional and the default is 3. If specified and the value is non-zero, the minimum value is 2 and the maximum value is 10. The servers are set up in an MSSQ set automatically.
OPENINFO = "string"
TMSNAME is not set or is set to TMS. The format of the OPENINFO string is dependent on the requirements of the vendor providing the underlying resource manager. The information required by the vendor must be prefixed with "rm_name:," which is the published name of the vendor's transaction (XA) interface followed immediately by a colon (:).
OPENINFO="TUXEDO/D:fsconfig:dbname:openmode"
where "TUXEDO/D" is the published name of the BEA TUXEDO XA interface, fsconfig is the name of the FSCONFIG on which the database resides, dbname is the name of the database, and openmode is one of "readonly" or "readwrite". For NT and NetWare, the colon separator after fsconfig and dbname must be a semi-colon.
For BEA TUXEDO system/SQL databases, the format is:
OPENINFO="TUXEDO/SQL:fsconfig:dbname:openmode"
where "TUXEDO/SQL" is the published name of the BEA TUXEDO system/SQL XA interface, fsconfig is the name of the FSCONFIG on which the database resides, dbname is the name of the database, and openmode is one of "readonly" or "readwrite". For NT and NetWare, the colon separator after fsconfig and dbname must be a semi-colon.
For BEA TUXEDO /Q databases, the format is:
OPENINFO="TUXEDO/QM:qmconfig:qspace"
where "TUXEDO/QM" is the published name of the BEA TUXEDO /Q XA interface, qmconfig is the name of the QMCONFIG on which the queue space resides and qspace is the name of the queue space. For NT and NetWare, the colon separator after qmconfig must be a semi-colon.
If TMSNAME is set but the OPENINFO string is set to the null string ("") or this parameter does not appear on the entry, it means that a resource manager exists for the group but does not require any information for executing an open operation.
CLOSEINFO = "string"
specifies the resource manager instance-dependent information needed when closing the resource manager. The value must be enclosed in double quotes and must be less than or equal to 256 characters in length. This value is ignored if TMSNAME is not set or is set to TMS. The format of the CLOSEINFO string is dependent on the requirements of the vendor providing the underlying resource manager. The information required by the vendor must be prefixed with "rm_name:," which is the published name of the vendor's transaction (XA) interface followed immediately by a colon (:). For BEA TUXEDO system/SQL databases, a CLOSEINFO string is not used. If TMSNAME is set but the CLOSEINFO string is set to the null string ("") or this parameter does not appear on the entry, it means that a resource manager exists for the group but does not require any information for executing a close operation.
The NETGROUPS section describes the network groups available to the application in the LAN environment. Any pair of machines may be in any number of network groups. Two communicating nodes use the priority mechanism in order to determine how to communicate between elements of its group.
Every LMID must be a member of the default network group, DEFAULTNET. Machines running BEA TUXEDO releases earlier than Release 6.4 (in which NETGROUPS became available) can belong only to the DEFAULTNET network group. The network group number (NETGRPNO) for DEFAULTNET. is 0 (zero), and may not be changed. The default priority of DEFAULTNET, however, may be modified.
The general format for entries in this section is:
NETGROUP required_parameters [ optional_parameters ]
where NETGROUP is the network group name. If NETGROUP is equal to DEFAULTNET then the entry describes the default network group.
Required parameters are:
NETGRPNO = numeric_value
DEFAULTNET, then the numeric value must be 0 (zero).
Optional parameters are:
NETPRIO = numeric_value
DEFAULTNET that can be altered.
NETGRPNO) within priority group number. In future releases, a different algorithm may be used to prioritize parallel data circuits.
The NETWORK section describes the network configuration for a LAN environment. For each processor on which a bridge server is located, an entry must be placed in the NETWORK section giving the network address of the bridge process. An error is generated if this section exists and LAN is not specified for the OPTIONS parameter of the RESOURCES section.
The general format for entries in this section is:
LMID required parameters [optional parameters]
where LMID is the logical machine where the bridge process is placed. LMID must have direct access to the network device to be used (as given in the BRIDGE parameter).
Required parameters are:
NADDR = string_value
"0xhex-digits" or "\\xhex-digits", it must contain an even number of valid hex digits. These forms are translated internally into a character array containing TCP/IP addresses may also be in either of the following two forms:
"//host.name:port_number""//#.#.#.#:port_number"
In the first of these formats, hostname is resolved to a TCP/IP host address at the time the address is bound using the locally configured name resolution facilities accessed via an operating system command. The "#.#.#.#" is the dotted decimal format where each # represents a decimal number in the range 0 to 255. Port_number is a decimal number in the range 0 to 65535. the hexadecimal representations of the string specified.
Optional parameters are:
BRIDGE = string_value
BRIDGE parameter is not required. In prior releases, for networks that were TLI-based, an absolute pathname for a device was required as the value of BRIDGE. The network transport endpoint file path has the form: /dev/provider_name. For StarLAN this is: /dev/starlan.
NLSADDR = string_value
tlisten(1) process servicing the network on the node identified by the LMID. The network address used for NLSADDR is of the same format as that specified for the NADDR parameter above. If the address has the form "0xhex-digits" or "\\xhex-digits", it must contain an even number of valid hex digits. TCP/IP addresses may be in the "//#.#.#.#:port" format. tmloadcf(1) prints an error if NLSADDR is missing on any entry but the MASTER LMID, for which it prints a warning. However, if NLSADDR is missing on the MASTER LMID, tmadmin(1) will not be able to run in administrator mode on remote machines; it will be limited to read-only operations. This also means that the backup site will be unable to to reboot the master site after failure.
MINENCRYPTBITS={0|40|128}
0 means no encryption, while 40 and 128 specify the encryption key length (in bits). If this minimum level of encryption cannot be met, link establishment will fail. The default is 0.
MAXENCRYPTBITS={0|40|128}
0 means no encryption, whilc 40 and 128 specify the encryption length (in bits). The default is 128
NETGROUP = string_value
DEFAULTNET, is assumed. The NETGROUP parameter, if not set to DEFAULTNET, must have previously appeared as a group name in the NETGROUPS section of the file. All network entries with aNETGROUP DEFAULTNET are represented in the T_MACHINE class of the TM_MIB, while NETWORK entries associated with any other NETGROUP are represented in the T_NETMAP class of the TM_MIB to interoperate with previous releases.
This section provides information on the initial conditions for servers started in the system. The notion of a server as a process that continually runs and waits for a server group's service requests to process, may or may not apply to a particular remote environment. For many environments, the operating system or perhaps a remote gateway will be the sole dispatcher of services; when either of these is the case, only SERVICE table entries (see next section) and no SERVER table entries need be specified for remote program entry points; BEA TUXEDO system gateway servers would advertise and queue remote domain service requests. Host-specific reference pages must indicate whether or not UBBCONFIG server table entries apply in their particular environments, and if so, the corresponding semantics. Lines within the SERVERS section have the form:
AOUT required parameters [optional parameters]
where AOUT specifies the file (string_value) to be executed by tmboot(1). tmboot executes AOUT on the machine specified for the server group to which the server belongs. tmboot searches for the AOUT file on its target machine. Thus, AOUT must exist in a filesystem on that machine. (Of course, the path to AOUT can include RFS connections to filesystems on other machines.) If a relative pathname for a server is given, the search for AOUT is done first in APPDIR, then in TUXDIR/bin, then in /bin, and then in path> where path> is the value of the last PATH= line appearing in the machine environment file, if one exists. The values for APPDIR and TUXDIR are taken from the appropriate machine entry in the TUXCONFIG file. See ENVFILE in the MACHINES section for a more detailed discussion.
Required parameters are:
SRVGRP = string_value
GROUPS section. It must be 30 characters or less. This association with an entry in the GROUPS section means that AOUT is executed on the machine with the LMID specified for the server group. It also specifies the GRPNO for the server group and parameters to pass when the associated resource manager is opened. All server entries must have a server group parameter specified.
SRVID = number
The optional parameters are divided into two categories: boot options and run-time options. Boot options are used by tmboot(1) when it executes a server. Once running, a server reads its entry from the configuration file to determine its run-time options. The unique server id is used to find the right entry.
Optional boot parameters are:
CLOPT = string_value
servopts(5) options to be passed to AOUT when booted. If none is specified, the default is -A. string_value can be up to 256 characters in length.
SEQUENCE = number
SEQUENCE parameter is not specified, servers are booted in the order found in the SERVERS section (and shut down in the reverse order). If a mixture of servers with and without sequence numbers is given, all servers with sequence numbers are booted first from low to high sequence number, then all servers without sequence numbers are booted in the order they appear in the configuration file. Sequence numbers must be in the range between 1 and 9999.
MIN = number
tmboot. If an RQADDR is specified and MIN is greater than 1, then the servers will form an MSSQ set. The server identifiers for the servers will be SRVID up to SRVID + MAX - 1. All occurrences of the server will have the same sequence number, as well as any other server parameters. The value range for MIN is 0 to 1000. If not specified, the default is 1.
MAX = number
tmboot boots MIN servers, and additional servers can be booted up to MAX occurrences using the -i option of tmboot to specify the associated server identifier. The value range for MAX is 0 to 1000. If not specified, the default is the same value as MIN.
Optional run-time parameters are:
ENVFILE = string_value
ENVFILE must be in the same location on both machines.
ENVFILE instead. See ENVFILE in the MACHINES section for a discussion of how this file is used to modify the environment.
CONV = { Y | N }
tpacall(3c) or tpcall(3c)) can only be made to non-conversational servers. The default is N.
RQADDR = string_value
GRPNO.SRVID) is chosen for a queue that AOUT accesses. Specifying the same RQADDR for more than one server is the way multiple server, single queue (MSSQ) sets are achieved. If two servers are given an RQADDR with the same queue name, they must be in the same server group.
RQPERM = number
RQPERM is not specified, and a PERM is specified in the RESOURCES section, then that value is used. Otherwise, a value 0666 is used. The value can be between 0001 and 0777, inclusive.
REPLYQ = { Y | N }
AOUT. If Y is specified, the reply queue is created on the same LMID as the AOUT. The default is N. For servers in an MSSQ set, servers that expect replies should have REPLYQ set to Y.
RPPERM = number
RPPERM is not specified, the default value 0666 is used. If requests and replies are both read from the same queue, only RQPERM need be specified; RPPERM is ignored. The value can be between 0001 and 0777, inclusive.
RCMD = string_value
AOUT is restartable, this parameter specifies the command that should be executed when AOUT abnormally terminates. The string, up to the first space or tab, must be the name of an executable UNIX file, either a full pathname or relative to APPDIR (don't attempt to set a shell variable at the beginning of the command). The command name may be optionally followed by command line arguments. Two additional arguments are appended to the command line: the GRPNO and SRVID associated with the restarting server. string_value is executed in parallel with restarting the server.
MAXGEN = number
GRACE. The value must be greater than 0 and less than 256. If not specified, the default is 1 (which means that the server can be started once, but not restarted).
GRACE = number
MAXGEN lives within the specified number of seconds. The value must be greater than or equal to 0 and less than 2147483648. If 0, the AOUT can be restarted an unlimited number of times. If GRACE is not specified, the default is 86,400 seconds (24 hours).
RESTART = { Y | N }
N. If server migration is specified, RESTART must be set to Y. Note that a server terminated with a SIGTERM signal cannot be restarted; it must be rebooted.
SYSTEM_ACCESS identifier[,identifier]
FASTPATH or PROTECTED. FASTPATH specifies that the internal tables should be accessible by the libraries via shared memory for fast access. PROTECTED specifies that while the internal tables are accessible by BEA TUXEDO system libraries via shared memory, the shared memory for these tables is not accessible outside of the BEA TUXEDO system libraries. NO_OVERRIDE can be specified (either alone or in conjunction with FASTPATH or PROTECTED) to indicate that the mode selected cannot be overridden by an application process. If SYSTEM_ACCESS is not specified, the default mode is determined by the setting of the SYSTEM_ACCESS keyword in the RESOURCES section.
This section provides information on services used by the application. Lines within the SERVICES section have the form:
SVCNM [optional parameters]
where SVCNM is the (string_value) name of the service. SVCNM must be 15 characters or fewer in length.
There are no required parameters. Services need not be listed if no optional parameters need to be set. Optional parameters are:
LOAD = number
PRIO = number
SRVGRP = string_value
SRVGRP allows the same service to have different parameter settings within different server groups. It must be 30 characters or less.
BUFTYPE = "type1[:subtype1[,subtype2 . . . ]][;type2[:subtype3[, . . . ]]] . . .
FML (for FML buffers), VIEW, X_C_TYPE, or X_COMMON (for FML views), STRING (for NULL terminated character arrays) and CARRAY or X_OCTET (for a character array that is neither encoded nor decoded during transmission). Of these types, only VIEW, X_C_TYPE, and X_COMMON have subtypes. A view subtype gives the name of the particular view expected by the service. Application types and subtypes can also be added (see tuxtypes(5)). For a TYPE that has subtypes, "*" can be specified for the subtype to indicate that the service accepts all subtypes for the associated type.
A single service can only interpret a fixed number of buffer types, namely those found in its buffer type switch (see tuxtypes(5)). If the BUFTYPE parameter is set to ALL, that service will accept all buffer types found in its buffer type switch. Omitting the BUFTYPE parameter is equivalent to setting it to ALL. If multiple entries exist for the same service name but with different SRVGRP parameters, the BUFTYPE parameter must be the same for all of these entries.
A type name can be 8 characters or less in length and a subtype name can be 16 characters or less in length. Note that type and subtype names should not contain semicolon, colon, comma, or asterisk characters (this will make it hard to see where type and subtype values end).
Some examples of valid BUFTYPE specifications are:
BUFTYPE=FML implies that the service takes FML buffers.
BUFTYPE=VIEW:* implies that the service takes all subtypes
of FML views.
ROUTING = string_value
SRVGRP parameters, the ROUTING parameter must be the same for all of these entries.
SVCTIMEOUT = number
SIGKILL signal. The default for this parameter is 0.
The following parameters are for DTP applications only:
AUTOTRAN = { Y | N }
N.
TRANTIME = number
This section provides information for data dependent routing of service requests using FML buffers and views. The routing criteria specified here are used only if the default routing functions, _froute and _vroute, are being used (see tuxtypes(5)). Lines within the ROUTING section have the form:
CRITERION_NAME required parameters
where CRITERION_NAME is the (string_value) name of the routing entry that was specified on the services entry. CRITERION_NAME must be 15 characters or less in length.
Required parameters are:
FIELD = string_value
FML buffer or view field name that is identified in an FML field table (using the FLDTBLDIR and FIELDTBLS environment variables) or an FML view table (using the VIEWDIR and VIEWFILES environment variables), respectively. This information is used to get the associated field value for data-dependent routing during the sending of a message. If a field in an FML32 buffer will be used for routing, it must have a field number less than or equal to 8191.
RANGES = "string"
string can be up to 1024 characters). The format of string is a comma-separated ordered list of range/group_name pairs (see "EXAMPLE" below).
A range is either a single value (signed numeric value or character string in single quotes), or a range of the form "lower - upper" (where lower and upper are both signed numeric values or character strings in single quotes). Note that "lower" must be less than or equal to "upper". To embed a single quote in a character string value (as in O'Brien, for example), it must be preceded by two backslashes ('O\\'Brien'). The value MIN can be used to indicate the minimum value for the data type of the associated FIELD on the machine. The value MAX can be used to indicate the maximum value for the data type of the associated FIELD on the machine. Thus, "MIN - -5" is all numbers less than or equal to -5 and "6 - MAX" is all numbers greater than or equal to 6. The meta-character "*" (wild-card) in the position of a range indicates any values not covered by the other ranges previously seen in the entry; only one wild-card range is allowed per entry and it should be last (ranges following it will be ignored).
The routing field can be of any data type supported in FML. A numeric routing field must have numeric range values, and a string routing field must have string range values.
String range values for string, carray, and character field types must be placed inside a pair of single quotes and can not be preceded by a sign. Short and long integer values are strings of digits, optionally preceded by a plus or minus sign. Floating point numbers are of the form accepted by the C compiler or atof: an optional sign, then a string of digits optionally containing a decimal point, then an optional e or E followed by an optional sign or space, followed by an integer.
The group name indicates the associated group to which the request is routed if the field matches the range. A group name of "*" indicates that the request can go to any group where a server offers the desired service.
Within a range/group pair, range is separated from the group name by a ":".
BUFTYPE = "type1[:subtype1[,subtype2 . . . ]][;type2[:subtype3[, . . . ]]] . . ."
FML, VIEW, X_C_TYPE, or X_COMMON. No subtype can be specified for type FML, and subtypes are required for type VIEW, X_C_TYPE, and X_COMMON ("*" is not allowed). Note that subtype names should not contain semicolon, colon, comma, or asterisk characters. Duplicate type/subtype pairs can not be specified for the same routing criteria name; more than one routing entry can have the same criteria name as long as the type/subtype pairs are unique. This parameter is required. If multiple buffer types are specified for a single routing entry, the data types of the routing field for each buffer type must be the same.
An example of a routing entry is:
BRNCH FIELD=B_FLD RANGES="0-2:DBG1,3-5:DBG2,6-9:DBG3" BUFTYPE="FML"
which sends buffers with field B_FLD values 0-2 to server group DBG1, values 3-5 to server group DBG2, and values 6-9 to DBG3; no other values are allowed.
If the field value is not set (for FML buffers), or does not match any specific range and a wild-card range has not been specified, an error is returned to the application.

In an interoperating application, the master site must be the latest release available. Parameter values for PMID (machine ADDRESS), LMID, TLOGNAME, group names, RQADDR, service names, and ROUTING (routing criteria names) must be identifiers (valid C identifiers that are not UBBCONFIG keywords) when interoperating with BEA TUXEDO system.
Suppose the local machine on which the bridge is being run is using TCP/IP addressing and is named backus.company.com, with address 155.2.193.18. Further suppose that the port number at which the bridge should accept requests is 2334. Assume that port number 2334 has been added to the network services database under the name bankapp-naddr. The address could be represented in the following ways:
//155.2.193.18:bankapp-naddr//155.2.193.18:2334
//backus.company.com:bankapp-naddr
//backus.company.com:2334
0x0002091E9B02C112
The last of these representations is hexadecimal format. The 0002 is the first part of a TCP/IP address. The 091E is the port number 2334 translated into a hexadecimal number. After that each element of the IP address 155.2.193.1 is translated into a hexadecimal number. Thus the 155 becomes 9B, 2 becomes 02 and so
