weblogic内存溢出outofmemory日志分析

软件环境: aix 6.1+weblogic10.3+oracle11
系统每天同时在线人数100左右,数据库的数据量有多张频繁操作的表数据记录在千万以上,主要后台自动处理线程过多。
系统前段时间运行一直正常,只是从7月底出现OOM,最近差不多半个月出现一次。
对weblogic产生的phd文件和javacore文件分析的不太清楚。。。
以下是javacore的日志:

WARNING Java heap is almost exhausted : 0% free Java heap Please enable verbosegc trace and use IBM Pattern Modeling and Analysis Tool(http://www.alphaworks.ibm.com/tech/pmat) to analyze garbage collection activities. If heapdumps are generated at the same time, please use IBM HeapAnalyzer(http://www.alphaworks.ibm.com/tech/heapanalyzer) to analyze Java heap.

Recommended -Xmxcl setting (only for IBM Java 5.0, up to and including Service Refresh 4 (build date:February 1st ,2007)) : 12,117 or greater

note: oNLY FOR jAVA 5.0 sERVICE rEFRESH 4 (BUILD DATE:fEBRUARY 1ST, 2007) AND OLDER. wHEN YOU USE DELEGATED CLASS LOADERS, THE jvm CAN CREATE A LARGE NUMBER OF cLASSlOADER OBJECTS. oN ibm jAVA 5.0 sERVICE rEFRESH 4 AND OLDER, THE NUMBER OF CLASS LOADERS THAT ARE PERMITTED IS LIMITED TO 8192 BY DEFAULT AND AN oUToFmEMORYeRROR EXCEPTION IS THROWN WHEN THIS LIMIT IS EXCEEDED. uSE THE -xMXCL PARAMETER TO INCREASE THE NUMBER OF CLASS LOADERS ALLOWED TO AVOID THIS PROBLEM, FOR EXAMPLE TO 25000, BY SETTING -xMXCL25000, UNTIL THE PROBLEM IS RESOLVED. pLEASE EXAMINE THE CURRENT THREAD STACK TRACE TO CHECK WHETHER A CLASS LOADER IS BEING LOADED IF THERE IS AN oUToFmEMORYeRROR. fOR EXAMPLE, THE FOLLOWING STACK TRACE INDICATES THAT A CLASS LOADER IS BEING LOADED: AT COM/IBM/OTI/VM/vm.INITIALIZEcLASSlOADER(nATIVE mETHOD) AT JAVA/LANG/cLASSlOADER.
