As EM12c introduced numerous features that has assisted its direction towards the center of the Oracle universe, the footprint became heavier, but I’ve been very impressed with development’s continued investment into lightening that footprint, even when considerable additions with plug-ins and metric extensions are added. One of the reasons that the management agent was created and OEM processing removed from an internal database backend process was to lighten the footprint. oracle_ - LOAD_TARGET_DYNAMIC running for 596 seconds oracle_database.rcvcat11 - LOAD_TARGET_DYNAMIC running for 596 seconds oracle_ - LOAD_TARGET_DYNAMIC running for 596 seconds oracle_ - LOAD_TARGET_DYNAMIC running for 596 seconds oracle_ - LOAD_TARGET_DYNAMIC running for 596 seconds oracle_ - LOAD_TARGET_DYNAMIC running for 596 seconds oracle_ - LOAD_TARGET_DYNAMIC running for 596 seconds oracle_ - LOAD_TARGET_DYNAMIC running for 596 seconds oracle_ - LOAD_TARGET_DYNAMIC running for 596 seconds Dynamic property executor tasks running - Agent is Running but Not Ready The output from the “emctl start agent” wasn’t showing him anything he didn’t already know, but I asked him to send me the output and the following showed the actual issue that was causing the Agent not to finish out the run: MaxThreads=96 agentJavaDefines=-Xmx345M -XX:MaxPermSize=96M SchedulerRandomSpreadMins=5 UploadMaxNumberXML=5000 UploadMaxMegaBytesXML=50.0 Auto tuning was successful - Tue Dec 9 12:50:04 2014::5216::Finished auto tuning the agent at time Tue Dec 9 12:50:04 2014 - Tue Dec 9 12:50:04 2014::5216::Launching the JVM with following options: -Xmx345M -XX:MaxPermSize=96M -server =file:///dev/./urandom =true -XX:+UseLinuxPosixThreadCPUClocks -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+UseCompressedOops - Agent is going down due to an OutOfMemoryError This host target was a unique environment in that it contained so many targets, especially targets. :)) a customer contacted me in regards to a challenge he was experiencing starting an agent on a host that was home to 100’s of targets.
