AGENT时区问题

1、因agent的时区与machine时区不匹配导致启动agent失败,解决在安装检查时区的检查的警告问题
解决问题：在利用12c MOS推送方式安装12c agent时，会出现时区检查的warning，上面提示利用emctl resetTZ agent在安装后处理。在做的过程中，可能遇到某些状况的解决方法
环境：HP_UNIX B.11.31
--查看agent状态
$ ./emctl status agent

resetTZ failed.
The agentTZRegion in:
/u01/app/agent_12c/agent_inst/sysman/config/emd.properties
is not in agreement with what the agent thinks it should be.
Fix your environment.
Pick a TZ value that corresponds to time zone settings listed in:
/u01/app/agent_12c/core/12.1.0.3.0/sysman/admin/supportedtzs.lst
$ ./emctl start agent

Starting agent ..... failed.
property 'agentTZregion' in '/u01/app/agent_12c/agent_inst/sysman/config/emd.properties' contains an invalid value of '+08:00'.Agent start up can not proceed.This value might have been manually modified to be an incorrect value.This value needs to be set to one of the  values listed in '/u01/app/agent_12c/core/12.1.0.3.0/sysman/admin/supportedtzs.lst'. Execute 'emctl config agent getTZ' and see if this is an appropriate value.
Consult emctl.log and emagent.nohup in: /u01/app/agent_12c/agent_inst/sysman/log

--更改session的TZ，此TZ选择与agentTZ所在的时区一致，配置agentTZ再启动agent，查看状态
$  export TZ=Asia/Shanghai
