Controlling the Size and Number of OPMN Debug logs generated

Incase you want to control the number and size of the files generated under SOA_HOME/opmn/logs directory, you can do that by adding few start up parameters in opmn.xml. Usually if these are not added, the debug files will grow over a period of time and will run out of space. (use du -csh * under logs directory to see space occupied by each sub-directory).

Usually the directory OC4J_SOA_xxxx which holds the *.out and *.err files consumes the most space. So to control that you can add below startup parameters for automatic recycling of these files.

<ias-component id="SOA" status="enabled">

            <process-type id="OC4J_SOA" module-id="OC4J" status="enabled">

               <module-data>

                  <category id="start-parameters">

                     <data id="java-options" value="-server -XX:MaxPermSize=2048M -ms4096M -mx8192M -XX:AppendRatio=3 -Djava.security.policy=$ORACLE_HOME/j2ee/OC4J_SOA/config/java2.policy -Djava.awt.headless=true -Dhttp.webdir.enable=false -Doc4j.userThreads=true -Doracle.mdb.fastUndeploy=60 -Doc4j.formauth.redirect=true -Djava.net.preferIPv4Stack=true -Dorabpel.home=/soa/OracleAS_1/bpel -Xbootclasspath^/p:/soa/OracleAS_1/bpel/lib/orabpel-boot.jar -Dhttp.proxySet=false -Doraesb.home=/soa/OracleAS_1/integration/esb -DHTTPClient.disableKeepAlives=true -Dhttp.session.debug=false -Dfile.encoding=UTF-8 -Dstdstream.filesize=10 -Dstdstream.filenumber=10"/>

                     <data id="oc4j-options" value="-out /soa/OracleAS_1/opmn/logs/OC4J_SOA.out -err /soa/OracleAS_1/opmn/logs/OC4J_SOA.err "/>

These 2 highlighted parameters control the size of each file as 10MB and number to 10. Older files are overwritten. Restart the server for changes to take affect.
