File Formats, Data Descriptions, MIBs, and System Processes Reference
The T_NETMAP
class associates TA_LMIDs
from the T_MACHINE
class in the TM_MIB
to a TA_NETGROUP
object from the T_NETGROUP
class. In other words, this class contains assignments of logical machines to network groups. A TA_LMID
may be included in many TA_NETGROUP
groups. When one LMID connects to another LMID, the Bridge process determines the subset of network groups to which the two LMIDs belong. When the pair of LMIDs are in several common groups, they are sorted in descending TA_NETPRIO
order (TA_NETGRPNO
is the secondary sort key). The Network groups with the same TA_NETPRIO
will flow network data in parallel. Should a networking error prevent data from flowing through all the highest priority group(s), only then the next lower priority network group(s) are used for network traffic (failover). All network groups with a higher priority than the ones flowing data are retried periodically. Once a network connection is established with a higher TA_NETPRIO
value, no further data is scheduled for the lower priority one. Once the lower priority connection is drained, it is disconnected in an orderly fashion (failback).
(r)—required field for object creation ( |
A GET
operation will retrieve run-time information for the selected T_NETMAP
object(s). The following states indicate the meaning of a TA_STATE
returned in response to a GET
request.
|
A SET
operation will update configuration information for the selected T_NETMAP
object. The following states indicate the meaning of a TA_STATE
set in a SET
request. States not listed cannot be set.
TA_NADDR
: string
[1..256] (up to 78 bytes for BEA Tuxedo 8.0 or earlier)
Specifies the complete network address to be used by the Bridge process placed in the logical machines as its listening address. The listening address for a Bridge is the means by which one Bridge process is contacted by others that are participating in the application, that is, if the LAN
option is set in the T_DOMAIN:TA_OPTIONS
attribute value.
If string
has the form "0x
hex-digits
"
, it must contain an even number of valid hex digits. These forms are translated internally into a character array containing the hexadecimal representations of the string specified.
TA_FADDR:
string
[0..256] (up to 78 bytes for BEA Tuxedo 8.0 or earlier)
Specifies the complete network address to which local processes such as tmboot
, tmloadcf
, and Bridge and can bind before making an outbound connection. This address must be a TCP/IP address. This attribute, along with the TA_FRANGE
attribute, determines the range of TCP/IP ports to which a process attempts to bind before making an outbound connection. If this attribute is set to the NULL or empty string, the operating system randomly chooses a local port with which to bind.
If string
has the form "0x
hex-digits
"
, it must contain an even number of valid hex digits. These forms are translated internally into a character array containing the hexadecimal representations of the string specified.
Specifies the range of TCP/IP ports to which local processes attempt to bind before making an outbound connection. The TA_FADDR
attribute specifies the base address of the range.
Specifies the minimum level of encryption required when a network link is being established. 0
means no encryption, while 40
, 56
, and 128
specify the encryption key length (in bits). If this minimum level of encryption cannot be met, link establishment fails. The default is 0
.
Note: The link-level encryption value of 40 bits is provided for backward compatibility.
Limitation: Modifications to this attribute will not effect established network links.
Specifies the maximum level of encryption allowed when a link is being established. 0
means no encryption, while 40
, 56
, and 128
specify the encryption length (in bits). The default is 128
.
Note: The link-level encryption value of 40 bits is provided for backward compatibility.
Limitation: Modifications to this attribute will not effect established network links.
When 128-bit encryption is licensed, TA_MAXENCRYPTBITS
defaults to 128
. When 56-bit encryption is licensed, the default is 56
. When no encryption is licensed, the default is 0
bits. Note that when Bridge processes connect, they negotiate to the highest common TA_MAXENCRYPTBITS
.
