aix +tomcat5.0.28+jdk1.42的内存问题？

aix +tomcat5.0.28+jdk1.42的内存问题？
我把以前的工程部署到了Aix上（以前的是windows服务器，运行1年多都很稳定的），访问是好的，但是运行一会儿就抱错，说是内存溢出：
**Out of memory, aborting**

界面错误是
javax.servlet.ServletException: JVMXE006:OutOfMemoryError, stAllocArray for executeJava failed

听说aix自带的虚拟机没有垃圾回收器，想放大JVM内存，但是不会设置，也不知道能不能解决，请大家帮帮忙！
我想设置heap 大小 -XMS等，但是不知道在哪里设置，我设置在 catalina.sh 文件中，但是tomcat一启动就停了。但不知道再哪里设置，能举个例子不？谢谢大家。 --------------------编程问答-------------------- server里面的进程定义有个jvm虚拟机可以调内存 --------------------编程问答-------------------- 换内存吧，我看就这 --------------------编程问答-------------------- 不会,帮顶 --------------------编程问答-------------------- JVMDG217: Dump Handler is Processing OutOfMemory - Please Wait.

系统启动时将jvm的内存设置大一些
