How to know memory allocated to particular instance of event server

[snehareddy]

Hi,

We have four instances of event servers running on UNIX system. Please let us know how we can know the memory allocated to the particular instance of event server.

Also please let us know which parameters needs to be changed in case we have components where we have large number of messages in the queue so that it should not affect other interfaces running on the event server.

The version we are using is Mercator 6.7(306_1EM)

Thanks in advance!!

Something like this would give you the process details including memory and CPU used:

ps -eo vsz,pmem,pcpu,pid,args

(this works on AIX, may need tweaking for another OS)

ps l `cat /mercatorqa/.launcherPID`

will give you details of a particular launcher process

Olly.

Hi,

We have 4 instances of event servers running on UNIX system. For each instance two process are running – Mercator process and Java process.

It has been observed that for instance 4 java process is taking around 98% of CPU utilization. We have number of MQ based system files on this instance which are processing high amount of messages. Is there any chance that these MQ based system files to cause the high CPU utilization on this instance?

Please let us know the reasons and remedy for this high CPU utilization problem.

Thanks in advance!!

As per your other thread, you should see the following processes:
/usr/java131/bin/java -DINSTALLDIR=/mercator/libs com.mercator.eventserver.core.EventServerManager

/mercator/bin/launcher /mercatorqa/systems/<system> /mercator/systems/<another system>

the Java process should use 0 CPU (leave it running a few hours before you check)- raise a call with IBM if its increasing or is high.

the launcher process should do all the mapping work and will have a non-zero CPU.
