Hi, Use following line in catalina file
set JAVA_OPTS=%JAVA_OPTS% -verbosegc -XX:+PrintGCDetails in windows change accordingly to linux. Run stratup.sh from command line: to see all heap information on console. On 7/19/06, Suresh babu <[EMAIL PROTECTED]> wrote:
Hi It's an option to the JVM, just append this line over there -verbosegc -XX:+PrintGCDetails. To avoid out of memmory errors just make sure minimum and maximum heap space should be same. You can find out still more information with GC details logged on enabling above option in JVM. Check it out how much memmory is reclaimimg on each GC and whats the frequency of minor or major GC are happening. More over you can set different alogorithms like copying collector.markand compavt/mark and sweep /incremental/throughput collectors in young/ old generation. You can find brief details in following links. http://java.sun.com/docs/hotspot/gc5.0/gc_tuning_5.html On 7/18/06, [EMAIL PROTECTED] <[EMAIL PROTECTED] > wrote: > > > Chris, > This gives how much heapsize is currently allocated. > How can I know whether it is enough or what size it should be > increased to? > Also: real time wise, how if tomcat behaving with each > event/interaction/page delivery? > > > Thanks, > Ibrahim > > > *Christopher Schultz < [EMAIL PROTECTED]>* > > 07/18/2006 09:00 AM > > Please respond to "Tomcat Users List" > > To: Tomcat Users List < users@tomcat.apache.org> > cc: > Subject: Re: Increase Heapsize > > > > Ibrahim, >> You can always call Runtime.getRuntime().totalMemory() to find out the >> amount of heap space that has been allocated to the JVM. > > Where would this code be written? > And how would I execute it? Just toss a JSP file somewhere with that code in it to allow you to check up on the app. -chris ****************************************************************************** This communication (including any attachments) may contain privileged or confidential information intended for a specific individual and purpose, and is protected by law.
