Can i set maximum connection-pool settings in JIRA-database connection in dbconfig.xml

[yogita chhaya]

We are facing problem of JIRA (version-6.4)becoming slow or it has to be restarted while there are multiple users(more than 150) accessing it.

We have 24GB physical memory and JAVA heap memory set to 1.5GB as we were getting GC errors as well as JVM heap-memory problems in JIRA

Can i try to change maximum connection-pool settings in JIRA in dbconfig.xml file?

Hi Yogita,

You need to update your jira version to a later version.

v6.4 sucks!

150 users is not that much.

 I don't see how this will help your situation. I would not change this setting unless I see an ORA-01000 (or similar for other db's) in the logs.

if you are getting GC errors, you need to optimize GC settings for your instance. Please see https://confluence.atlassian.com/enterprise/garbage-collection-gc-tuning-guide-461504616.html

I would recommend G1GC for a large jira instance (issues>5000).

As a general rule, increase the available system resources ,if jira is becoming slow or restarting. This is most probably a performance bottleneck.
