dmadmin-BEA TUXEDO Domain Administration Command Interpreter
dmadmin[-c]
dmadmin is an interactive command interpreter used for the administration of domain gateway groups defined for a particular BEA TUXEDO application. dmadmin can operate in two modes: administration mode and configuration mode.
dmadmin enters administration mode when called with no parameters. This is the default. In this mode, dmadmin can be run on any active node (excluding workstations) within an active application. Application administrators can use this mode to obtain or change parameters on any active domain gateway group. Application administrators may also use this mode to create, destroy, or reinitialize the DMTLOG for a particular local domain. In this case, the domain gateway group associated with that local domain must not be active, and dmadmin must be run on the machine assigned to the corresponding gateway group.
dmadmin enters configuration mode when it is invoked with the -c option or when the config subcommand is invoked. Application administrators can use this mode to update or add new configuration information to the binary version of the domain configuration file (BDMCONFIG).
dmadmin requires the use of the DOMAIN administrative server (DMADM) for the administration of the BDMCONFIG file and the gateway administrative server (GWADM) for the re-configuration of active DOMAIN gateway groups (there is one GWADM per gateway group).
Once dmadmin has been invoked, commands may be entered at the prompt (">") according to the following syntax:
command[arguments]
Several commonly occurring arguments can be given defaults via the default command. Commands that accept parameters set via the default command check default to see if a value has been set. If one hasn't, an error message is returned.
Once set, a default remains in effect until the session is ended, unless changed by another default command. Defaults may be overridden by entering an explicit value on the command line, or unset by entering the value "*". The effect of an override lasts for a single instance of the command.
Output from dmadmin commands is paginated according to the pagination command in use (see the paginate subcommand below).
Commands may be entered either by their full name or their abbreviation (shown in parentheses) followed by any appropriate arguments. Arguments appearing in square brackets, [], are optional; those in curly braces, {}, indicate a selection from mutually exclusive options. Note that for many commands local_domain_name is a required argument, but note also that it can be set with the default command.
The following commands are available in administration mode:
advertise (adv) -d local_domain_name [{ | service}]
audit (audit) -d local_domain_name [{off | on}]
chbktime (chbt) -d local_domain_name -t bktime
config (config)
connect (co) -d local_domain_name [-R remote_domain_name]
-R is not specified, then the command applies to all remote domains configured for this local gateway.)
crdmlog (crdlog)[-d local_domain_name]
dmadmin is running). The command uses the parameters specified in the DMCONFIG file. This command fails if the named local domain is active on the current machine or if the log already exists.
default (d) [-d local_domain_name]
disconnect (dco) -d local_domain_name [-R remote_domain_name]
-R is not specified, then the command applies to all remote domains configured for this local gateway.)
dsdmlog (dsdlg) -d local_domain_name [ -y ]
DMTLOG is not defined for this local domain, if the local domain is active, or if outstanding transaction records exist in the log. The term outstanding transactions means that a global transaction has been committed but an end-of-transaction has not yet been written. This command prompts for confirmation before proceeding unless the -y option is specified.
echo (e) [{off | on}]
forgettrans (ft) -d local_domain_name [ -t tran_id]
tran_id is specified, then only the heuristic log record for that transaction will be forgotten. The transaction identifier tran_id can be obtained from the printtrans command or from the ULOG file.
help (h) [command]
indmlog (indlg) -d local_domain_name [ -y ]
dmadmin is running). An error is returned if a DMTLOG is not defined for this local domain, if the local domain is active, or if outstanding transaction records exist in the log. The term outstanding transactions means that a global transaction has been committed but an end-of-transaction has not yet been written. The command prompts for confirmation before proceeding unless the -y option is specified.
paginate (page) [{off | on}]
PAGER may be used to override the default command used for paging output. The default paging command is the indigenous one to the native operating system environment, for example, the command pg is the default on UNIX System operating environments.
passwd (passwd) [ -r ] local_domain_name remote_domain_name
printdomain (pd) -d local_domain_name
printstats (pstats) -d local_domain_name
printtrans (pt) -d local_domain_name
quit (q)
resume (res) -d local_domain_name [{ -all | service}]
stats (stats) -d local_domain_name [{ off | on | reset }]
suspend (susp) -d local_domain_name [{ -all | service}]
unadvertise (unadv) -d local_domain_name [{ -all | service}]
verbose (v) [{off | on}]

# [text]
<CR>
The dmadmin command enters configuration mode when executed with the -c option or when the config subcommand is used. In this mode, dmadmin allows run-time updates to the BDMCONFIG file. dmadmin manages a buffer that contains input field values to be added or retrieved, and displays output field values and status after each operation completes. The user can update the input buffer using any available text editor.
dmadmin first prompts for the desired section followed by a prompt for the desired operation.
The prompt for the section is as follows:
Section:
1) RESOURCES 2) LOCAL_DOMAINS
3) REMOTE_DOMAINS 4) LOCAL_SERVICES
5) REMOTE_SERVICES 6) ROUTING
7) ACCESS_CONTROL 8) PASSWORDS
9) TDOMAINS 10) OSITPS
11) SNADOMS 12) LOCAL_REMOTE_USER
13) REMOTE_USERS 14) SNACRMS
15) SNASTACKS 16) SNALINKS
17) QUIT
Enter Section [1]:
The number of the default section appears in square brackets at the end of the prompt. You can accept the default by pressing RETURN or ENTER. To select another section enter its number, then press RETURN or ENTER.
dmadmin then prompts for the desired operation.
Operations:
1) FIRST 2) NEXT
3) RETRIEVE 4) ADD
5) UPDATE 6) DELETE
7) NEW_SECTION 8) QUIT
Enter Operation [1]:
The number of the default operation is printed in square brackets at the end of the prompt. Pressing RETURN or ENTER selects this option. To select another operation enter its number, then press RETURN or ENTER.
The currently supported operations are:
FIRST - Retrieve the first record from the specified section. No key fields are
needed (they are ignored if in the input buffer).
For configuration operations, the effective user identifier must match the BEA TUXEDO administrator user identifier (UID) for the machine on which this program is executed. When a record is updated or added, all defaults and validations used by dmloadcf(1) are enforced.
dmadmin then prompts whether or not to edit the input buffer. Enter editor to add/modify fields [n]?Entering a value of y will put the input buffer into a temporary file and execute the text editor. The environment variable EDITOR is used to determine which editor is to be used; the default is "ed". The input format is in field name/field value pairs and is described in the "CONFIGURATION INPUT FORMAT" section below. The field names associated with each DMCONFIG section are listed in tables in the subsections below. The semantics of the fields and associated ranges, defaults, restrictions, etc, are described in dmconfig(5). In most cases, the field name is the same as the KEYWORD in the DMCONFIG file, prefixed with "TA_". When the user completes editing the input buffer, dmadmin reads it. If more than one line occurs for a particular field name, the first occurrence is used and other occurrences are ignored. If any errors occur, a syntax error will be printed and dmadmin prompts whether or not to correct the problem. Enter editor to correct?
If the problem is not corrected (response n), then the input buffer will contain no fields. Otherwise, the editor is executed again.
Finally, dmadmin asks if the operation should be done. Perform operation [y]?
When the operation completes, dmadmin prints the return value as in Return value TAOK followed by the output buffer fields. The process then begins again with a prompt for the section. All output buffer fields are available in the input buffer unless the buffer is cleared.
Entering break at any time restarts the interaction at the prompt for the section.
When "QUIT" is selected, dmadmin prompts for authorization to create a backup ASCII version of the configuration: Unload BDMCONFIG file into ASCII backup [y]?If a backup is selected, dmadmin prompts for the file name. Backup filename [DMCONFIG]. On success, dmadmin indicates that a backup was created; otherwise, an error is printed.
Input packets consist of lines formatted as follows:
fldname fldval
The field name is separated from the field value by one or more tabs (or spaces).
Lengthy field values can be continued on the next line by having the continuation line begin with one or more tabs (which are dropped when read back into dmadmin).
Empty lines consisting of a single newline character are ignored.
To enter an unprintable character in the field value or to start a field value with a tab, use a backslash followed by the two-character hexadecimal representation of the desired character (see ASCII(5) in a UNIX reference manual). A space, for example, can be entered in the input data as \20. A backslash can be entered using two backslash characters. dmadmin recognizes all input in this format, but its greatest usefulness is for non-printing characters.
The following are general limitations of the dynamic domain reconfiguration capability:
The following sections describe, for each Restrictions for Configuration Field Identifiers/
UpdatesDMCONFIG section, what the field identifiers are associated with each DMCONFIG field, what the field type of the identifier is, and when the field can be updated. All applicable field values are returned with the retrieval operations. Fields that are allowed and/or required for adding a record are described in dmconfig(5). Fields indicated below as key are key fields that are used to uniquely identify a record within section These key fields are required to be in the input buffer when updates are done and are not allowed to be updated dynamically. The Update column indicates when a field can be updated. The possible values are:
Yes-Can be updated at any time.
NoGW-Cannot be updated dynamically while the gateway group representing the local domain is running.
No-Cannot be updated dynamically while at least one gateway group is running.

The The return value printed by The following return values indicate a problem with permissions or a BEA TUXEDO communications error. They indicate that the operation did not complete successfully.
TA_LPWD and TA_RPWD show the existence of a defined password for the local and/or the remote domain. Passwords are not displayed. If an UPDATE operation is selected, the value of the corresponding field must be set to U. The program will then prompt with echo turned off for the corresponding passwords.
Diagnostics in Configuration Mode
dmadmin fails if it cannot allocate an FML typed buffer, if it cannot determine the /etc/passwd entry for the user, or if it cannot reset the environment variables FIELDTBLS or FLDTBLDIR.
dmadmin after each operation completes indicates the status of the requested operation. There are three classes of return values.
TAEPERM]
ADD, UPDATE, or DELETE operation but it is not running as the BEA TUXEDO administrator. Update operations must be run by the administrator (that is, the user specified in the UID attribute of the RESOURCES section of the TUXCONFIG file).
TAESYSTEM]
userlog(3).
TAEOS]
TAETIME]
The following return values indicate a problem in doing the operation itself and generally are semantic problems with the application data in the input buffer. The string field TA_STATUS will be set in the output buffer and will contain short text describing the problem. The string field TA_BADFLDNAME will be set to the field name for the field containing the value that caused the problem (assuming the error can be attributed to a single field).
TAECONFIG]
BDMCONFIG file.
TAEDUPLICATE]
TAEINCONSIS]
TAENOTFOUND]
TAENOSPACE]

TAERANGE]
TAEREQUIRED]
TAESIZE]
TAEUPDATE]
The following return values indicate that the operation was successful.
TAOK]
BDMCONFIG file.
TAUPDATED]
BDMCONFIG file.
When using dmunloadcf to print entries in the configuration, optional field values are not printed if they are not set (for strings) or 0 (for integers). These fields will always appear in the output buffer when using dmadmin. In this way, it makes it easier for the administrator to retrieve an entry and update a field that previously was not set. The entry will have the field name followed by a tab but no field value.
In the following example, dmadmin is used to add a new remote domain. For illustration purposes, ed(1) is used for the editor.

The dmadmin program ends.
If dmadmin is run with the application administrator's UID, it assumes a trusted user and Security is bypassed. If dmadmin is run with another user ID, and if the security option is enabled in the TUXCONFIG file, then the corresponding application password is required to start the dmadmin program. If standard input is a terminal, then dmadmin will prompt the user for the password with echo turned off. If standard input is not a terminal, the password is retrieved from the environment variable, APP_PW. If this environment variable is not specified and an application password is required, then dmadmin will fail to start.
When running with another user ID (other than the UID of the administrator) only a limited set of commands is available.
dmadmin resets the FIELDTBLS and FLDTBLDIR environment variables to pick up the ${TUXDIR}/udataobj/dmadmin field table. Hence, the TUXDIR environment variable should be set correctly.
If the application requires security and the standard input to dmadmin is not from a terminal, then the APP_PW environment variable must be set to the corresponding application password.
The TUXCONFIG environment variable should be set to the pathname of the BEA TUXEDO configuration file.
If the dmadmin command is entered before the system has been booted, the following message is displayed:
No bulletin board exists. Only logging commands are available.
dmadmin then prompts for the corresponding commands.
If an incorrect application password is entered or is not available to a shell script through the environment, then a log message is generated, the following message is displayed, and the command terminates: Invalid password entered.
dmadmin must be installed on BEA TUXEDO R5.0 or later. Other nodes in the same domain with an R5.0 gateway may be BEA TUXEDO R4.1 or later.
dmadmin is supported as a BEA TUXEDO-supplied administrative tool on UNIX operating systems only.
