Inside Jira, look at the system information page.  From a command line on the server, the output from ps -ef will give you the flags the JVM is running with.

Sorry Nic i tried both( search under system info AND in server i search

ps -ef|grep jira)  but i didn't get GC mode in my jira.

[Nic Brough -Adaptavist-]

Both options tell you the flags the JVM is running with, including any GC options.  If none are set, then it is running with the defaults

thanks a lot Nic,

How can i change default to G1 mode(this is not clear, this information related JVM not GC mode https://community.atlassian.com/t5/Jira-questions/Jira-Improvement-Change-Java-GC-mode-switch-to-G1/qaq-p/794179) , please give me exact solution for change GC mode.

Thanking you in Advance.

Sorry Nic,

i read properly, there is a information related JVM increase and setenv.sh(JVM_SUPPORT_RECOMMENDED_ARGS=) in Args i didn't found GC type in my jira and some articals about G1 mode but there is no exact process of change mode(default to G1), still i didn't get my GC mode type. please tell me exact path and how we can change default to G1.

thanking you in Advance.

There's no point in me copying and pasting from that answer and the linked docs.  I can't tell you more than they do.
