Dear all, I am looking for solution for 24 Dspace for 24 communities run on 1 server. Which solution I should choose:
1) 24 instances of Tomcat, one for each Dspace instance, or 2) One Tomcat for 24 Dspace instances. I choose second solution by following the link http://www.nabble.com/Changing-DB-Name-%C2%BFhow--td19053520.html and already finished installation. But my server is broken if I try to access 24 DSpace at the same time (it is ok to open 12 Dspace). Some sites show error: java.lang.OutOfMemoryError: PermGen space The others return errors: java.io.FileNotFoundException: /usr/local/gmseenet/partners/gmseenet/dspace/webapps/jspui/WEB-INF/web.xml (Too many open files) or: org.apache.jasper.JasperException: Unable to compile class for JSP I already set heap memory for Tomcat to 2048 by JAVA_OPTS="-Xmx2048M -Xms64M -Dfile.encoding=UTF-8", but I still face the same problem. I have to run 24 DSpace in 1 machine, so what is solution for me? Please help me. Thanks in advance.
