GABPORT(1M)

NAME

gabport - Utility to configure and display information about Group and Atomic Broadcast (GAB) ports

SYNOPSIS

gabport -p port[-h timeout ]

DESCRIPTION

The 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.

OPTIONS

-p port The port to query or change the timeout value. port is specified as GAB port names a-z.
-h timeout
  Specify a heartbeat timeout value(in milliseconds) for a client process. The heartbeat statistics are reset by this command.
-d Display port membership. If the port is used by a user client, it also displays the client process heartbeat statistics.

EXAMPLES

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
