[Dspace-tech] Question about tomcat 6 or 7
Hi... I am running DSpace 1.7.1 with apache-tomcat-5.5.26 and jdk1.6.0_07. Everything works fine except to the Solr Stats. If I do a http://localhost:8080/solr/statistics/admin, I get an error display and clicking on the View Statistics button results in an error like Error using query type: 3 AND id:431 So, I tried switching to apache-tomcat-6.0.32. I was able now to execute the http://localhost:8080/solr/statistics/admin, but if I try to view a Collection or an Item, I get a java.lang.OutOfMemoryError: PermGen space Error I tried apache-tomcat-7.0.14, and I got the same error. I was using JAVA_OPTS=-server -Xms1024m -Xmx2048m -Xmn64m -Dfile.encoding=UTF-8 -XX:+UseParallelGC -verbose:gc -Xloggc:/dspace/dspace/log/gc.log I also tried CATALINA_OPTS=-Xms256m -Xmx1028m -XX:MaxPermSize=256m But neither of those helped. I know a lot has been written about memory leaks and what can be done, but I think I'm doing teh right stuff, but nothhing seems to be working. ANy idea would be appreciated.

[Dspace-tech] Question about tomcat 6 or 7 - follow up!
Hi... As is always the case...after I sent out an email in final desperation, I find the solution!. I had left out some of my JAVA_OPTS parameters to handle the java OutofMemory problem. Sorry to bother everyone. Here is what fixed things: JAVA_OPTS=-server -Xms1024m -Xmx2048m -Xmn64m -Dfile.encoding=UTF-8 -XX:+UseParallelGC -verbose:gc -Xloggc:/dspace/dspace/log/gc.log -XX:+HeapDumpOnOutOfMemoryError -XX:PermSize=1024m -XX:MaxPermSize=1024m -XX:-UseGCOverheadLimit George Kozak Digital Library Specialist Cornell University Library Information Technologies (CULIT) 501 Olin Library Cornell University Ithaca, NY 14853 607-255-8924 From: George S Kozak [g...@cornell.edu] Sent: Thursday, May 26, 2011 1:20 PM To: dspace-tech@lists.sourceforge.net Subject: [Dspace-tech] Question about tomcat 6 or 7 Hi...

I know a lot has been written about memory leaks and what can be done, but I think I'm doing teh right stuff, but nothhing seems to be working. It probably depends on your OS. On Gentoo I use something like this (in /etc/conf.d/tomcat-6): JAVA_OPTS=-Xmx1024M -Xms128M JAVA_OPTS=$JAVA_OPTS -Dfile.encoding=UTF-8 JAVA_OPTS=$JAVA_OPTS -XX:PermSize=192M JAVA_OPTS=$JAVA_OPTS -XX:MaxPermSize=512M Adjust the actual numbers to suit your site. Using a monitoring app like LambdaProbe can help you dial them in. Your JAVA_OPTS aren't addressing PermGen so they didn't help with that. Your CATALINA_OPTS do but I don't know what your OS does with (or to) that when it starts up Tomcat. (Tomcat startup tends to be an incredible Rube Goldberg construction for some reason.) -- Mark H.
