Table: VCS environment variables
Environment Variable |
Definition and Default Value |
||
---|---|---|---|
PERL5LIB |
Root directory for Perl executables. (applicable only for Windows) Default: Install Drive:\Program Files\VERITAS\cluster server\lib\perl5. |
||
VCS_CONF |
Root directory for VCS configuration files. Default: /etc/VRTSvcs
|
||
VCS_CONN_INIT_QUOTA |
Maximum number of simultaneous connections accepted by the VCS engine (HAD) per client host that has not completed the handshake. |
||
VCS_CONN_HANDSHAKE_TIMEOUT |
Timeout in seconds after which the VCS engine (HAD) closes the client connection that has not completed the handshake. |
||
VCS_DEBUG_LOG_TAGS |
Enables debug logs for the VCS engine, VCS agents, and HA commands. You must set VCS_DEBUG_LOG_TAGS before you start HAD or before you execute HA commands. See Enabling debug logs for the VCS engine. You can also export the variable from the |
||
VCS_DOMAIN |
The Security domain to which the VCS users belong. Symantec Product Authentication Service uses this environment variable to authenticate VCS users on a remote host. Default: Fully qualified host name of the remote host as defined in the VCS_HOST environment variable or in the .vcshost file. |
||
VCS_DOMAINTYPE |
The type of Security domain such as unixpwd, nt, nis, nisplus, ldap, or vx. Symantec Product Authentication Service uses this environment variable to authenticate VCS users on a remote host. Default: unixpwd |
||
VCS_DIAG |
Directory where VCS dumps HAD cores and FFDC data. |
||
VCS_ENABLE_LDF |
Designates whether or not log data files (LDFs) are generated. If set to 1, LDFs are generated. If set to 0, they are not. |
||
VCS_HOME |
Root directory for VCS executables. Default: /opt/VRTSvcs
|
||
VCS_HOST |
VCS node on which ha commands will be run. |
||
VCS_GAB_PORT |
GAB port to which VCS connects. Default: h |
||
VCS_GAB_TIMEOUT |
Timeout in milliseconds for HAD to send heartbeats to GAB. Default: 30000 (denotes 30 seconds) Range: 30000 to 300000 (denotes 30 seconds to 300 seconds) If you set VCS_GAB_TIMEOUT to a value outside the range, the value is automatically reset to 30000 or 300000, depending on the proximity of the value to the lower limit or upper limit of the range. For example, the value is reset to 30000 if you specify 22000 and to 300000 if you specify 400000. Irrespective of the values set, VCS_GAB_TIMEOUT_SECS overrides VCS_GAB_TIMEOUT if both are specified.
|
||
VCS_GAB_TIMEOUT_SECS |
Timeout in seconds for HAD to send heartbeats to GAB under normal system load conditions. Default: 30 seconds Range: 30 seconds to 300 seconds If you set VCS_GAB_TIMEOUT_SECS to a value outside the range, the value is automatically reset to 30 or 300, depending on the proximity of the value to the lower limit or upper limit of the range. For example, the value is reset to 30 if you specify 22 and to 300 if you specify 400. Irrespective of the values set, VCS_GAB_TIMEOUT_SECS overrides VCS_GAB_TIMEOUT if both are specified.
|
||
VCS_GAB_PEAKLOAD_TIMEOUT_SECS |
Timeout in seconds for HAD to send heartbeats to GAB under peak system load conditions. Default: 30 seconds Range: 30 seconds to 300 seconds To set the GAB tunables in adaptive mode, you must set VCS_GAB_PEAKLOAD_TIMEOUT_SECS to a value that exceeds VCS_GAB_TIMEOUT_SECS. If you set VCS_GAB_PEAKLOAD_TIMEOUT_SECS to a value that is lower than VCS_GAB_TIMEOUT_SECS, it is reset to VCS_GAB_TIMEOUT_SECS.
|
||
VCS_GAB_RMTIMEOUT |
Timeout in milliseconds for HAD to register with GAB. Default: 200000 (denotes 200 seconds) If you set VCS_GAB_RMTIMEOUT to a value less than 200000, the value is automatically reset to 200000. |
||
VCS_GAB_RMACTION |
Controls the GAB behavior when VCS_GAB_RMTIMEOUT exceeds. You can set the value as follows:
Default: SYSLOG |
||
VCS_HAD_RESTART_TIMEOUT |
Set this variable to designate the amount of time the hashadow process waits (sleep time) before restarting HAD. 0 |
||
VCS_LOG |
Root directory for log files and temporary files. You must not set this variable to "" (empty string). Default: /var/VRTSvcs
|
||
VCS_SERVICE |
Name of configured VCS service. Default: vcs-app
See Cluster attributes. |
||
VCS_TEMP_DIR |
Directory in which temporary information required by, or generated by, hacf is stored. Default: /var/VRTSvcs This directory is created in /tmp under the following conditions:
