websphere错误

websphere Java虚拟机内存修改过大启动报错

解决方法
找到配置文件：
/opt/IBM/WebSphere/AppServer/profiles/AppSrv01/config/cells/CMMI-CONTRBTNode01Cell/nodes/CMMI-CONTRBTNode01/servers/server1下的server.xml修改-Xmo 的值等于 -Xms，启动websphere，问题解决

错误现象：
ADMU0116I: Tool information is being logged in file
           /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/logs/server1/startServer.log
ADMU0128I: Starting tool with the AppSrv01 profile
ADMU3100I: Reading configuration for server: server1
ADMU3200I: Server launched. Waiting for initialization status.
ADMU3011E: Server launched but failed initialization. startServer.log,
           SystemOut.log(or job log in zOS) and other log files under
           /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/logs/server1 should
           contain failure information.
