前段时间，某客户想安装一套EM13c，在安装的过程中遇到一些错误，记录之。
在OMS初始化的过程中报错，错误日志如下所示。
INFO: oracle.sysman.top.oms:COMMAND: /u01/app/em13c/oms/bin/omsca NEW -RESPONSE-FILE=/u01/app/em13c/oms/omsarespfile...
INFO: oracle.sysman.top.oms:Error occured during initialization of VM INFO: oracle.sysman.top.oms:Error Could not create the java Virtual Machine INFO: oracle.sysman.top.oms:Error A fatal exception has occurred Program will exit INFO: oracle.sysman.top.oms:Error Could not reserve enough space for object heap |
看着像是JVM的问题，搜索MOS网站，发现EM 12c Agent Deployment Fails With Error "Error occurred during initialization of VM" (Doc ID 1488163.1)，这篇文章中提到需要设置JAVA的变量。
export _JAVA_OPTIONS="-Xms256m -Xmx512m" export EM_COMMON_JAVA_OPTIONS="-Xms256m -Xmx512m" |
虽然这篇文章是基于EM 12c的，但应该也差不多，所以尝试了下。
在当前环境设置该环境变量，清理了当前环境后， 并重新安装，果然不再报错，EM13c顺利安装完成。
