RTC Performance getting slower


praveen patidar (8613044) | asked Feb 01 '15, 11:59 p.m.
 Hello Team,

we have RTC 403 installed on WAS7.1.1.3 OS RedHat Linux DB Oracle 11G . JVM set for initial and maximum heap size to 4096.. total RAM is 12 GB. total DB size 300 GB. 

We are getting user activities less responsive , sometime unresponsive during peak hours. It is happening now only. We checked everything. one wired thing is RAM usage goes like 400% not sure what is counting. 



Generic JVM Argument is
-XX:MaxPermSize=1024m -Xmx4g -Xms4g -Xmn512m -Xgcpolicy:gencon -Xcompressedrefs -Xgc:preferredHeapBase=0x100000000

  1. Is this server being used for scm/build activity?
  2. What is th emin/max webcontainer thread pool set to
  3. In the Websphere systemOut.log do you see any hung thread messages
  4. How many cncurrent users are there
  5. Are there any users with backlevel clients such as RTC 3.0.1/ 4.0.2,..ext.

Things I would check:

  • Active services on the Application page
  • io activity on the server ( iostat ) or nmon
  • paging activity ( vmstat )
You can determine the measure of client versions on the "Counters" page which can be reached by adding ?internal=true after /admin and before any other part of the admin url.   e.g. /jazz/admin#action=jazz.viewPage&id=com.ibm.team.repository.server  would be come /jazz/admin?internal=true#action=jazz.viewPage&id=com.ibm.team.repository.server   Click on Counters under Internal tools, look for "Compatable client logins"
