VCS 6.1 – How to configure and display information about Group and Atomic Broadcast (GAB) ports

vcs-how-toThe gabport utility displays GAB port information or changes the heartbeat timeout value of a user client process on a GAB port. In normal operation, a GAB client process should heartbeat to GAB at a certain interval. GAB uses this mechanism to monitor the aliveness of a GAB user client process. If a client process does not heartbeat in the predefined timeout period, GAB kills the client. As a result, the port is closed.
1) Display information about a port used by a user client
# gabport -p h Port h
Information:
========================================================
Flags: 0xe00
Membership: gab01 gab02 gab04
heartbeat timeout: 15000 (msec)
heartbeat warn interval: 1000 (msec)
heartbeat statistics:
0 ~ 3000 (msec): 4177
3000 ~ 6000 (msec): 0
6000 ~ 9000 (msec): 0
9000 ~ 12000 (msec): 0
12000 ~ 15000 (msec): 0
2) Change the client process timeout value to 16 seconds
# gabport -p h -h 16000 Port h
new heartbeat timeout: 16000 msecs

I have started unixadminschool.com ( aka gurkulindia.com) in 2009 as my own personal reference blog, and later sometime i have realized that my leanings might be helpful for other unixadmins if I manage my knowledge-base in more user friendly format. And the result is today's' unixadminschool.com. You can connect me at - https://www.linkedin.com/in/unixadminschool/
