Why does the Insight report server switch to standby mode after some time?
My Insight 1.1.1.3 report server, installed on Linux RHEL 5, works fine after being started; but after some time the content manager switches to standby mode and the report server stops working.
The Websphere logs for the Insight profile show the following exception: java.util.zip.ZipException: Exception in opening zip file: /opt/IBM/WebSphere/AppServer/plugins/com.ibm.ffdc.jar at org.eclipse.osgi.framework.util.SecureAction.getZipFile(SecureAction.java:264) at org.eclipse.osgi.baseadaptor.bundlefile.ZipBundleFile.basicOpen(ZipBundleFile.java:88) at org.eclipse.osgi.baseadaptor.bundlefile.ZipBundleFile.getZipFile(ZipBundleFile.java:101) at org.eclipse.osgi.baseadaptor.bundlefile.ZipBundleFile.checkedOpen(ZipBundleFile.java:74) at org.eclipse.osgi.baseadaptor.bundlefile.ZipBundleFile.getEntry(ZipBundleFile.java:246) at com.ibm.cds.CDSBundleFile.getEntry(CDSBundleFile.java:92) ... How do I fix it? |

The limit of open files is set too low.
According to the requirements it must be 65536. See: Additional configuration requirements for Linux and AIX operating systems http://pic.dhe.ibm.com/infocenter/rentrpt/v1r1m1/topic/com.ibm.rational.raer.install.doc/topics/c_install_req_linux.html To see the current limit you can use [root@report ~]# ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 40960 max locked memory (kbytes, -l) 32 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 10240 cpu time (seconds, -t) unlimited max user processes (-u) 40960 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited To change it add the following lines in /etc/security/limits.conf : * hard nofile 65536 * soft nofile 65536 and restart the linux server. |
