I have an application web based. using Oracle backend and Java front end.
App server is in weblogic and Solaris os and two cpu with 8 applications.
DB server is oracle 8.1.7 on Solaris
This application is getting slow when number of threads are more ( like many users login and related activities) . I found out that during the peak time the garbage collector is also not running properly.
I want to know how can we change the GC algorithm ( like concurrent GC / parallel GC etc )
Where do we give the settings of JVM ?
How to enable the parallel GC ?
How to set the heap size ?
