EM agent 12.1 割接主机后重部署 agent is blocked, and “out-of-sync with repository”
ORACLE DB 有时出于硬件维护等情况需要更换主机操作，但IP,DB实例等都未改变, 这时在割接后的机器需要重新部署EM_AGENT ， 我通常是离线安装, 离线安装EM ANGENT 12参考我之前的笔记Acquiring Management Agent Software for HPUX&AIX in the Offline Mode(离线安装EM agent)，OMS 端原target 不需要删除在重新填加， 但是重部署后的EM_agent 通过emctl status agent 状态会是blocked,这时重新同步一下即可。

解决方法， 登录 OMS WEB
EM
左上角 targets
all targets
agent_blocked
选择target type是agent的目标， 右键 resynchronisation , 然后continue ，ok 的确认 跳到了agnet 主页 ，等待几分钟后正常.
同步过程中开始可能显示

原主机上的em agent 卸载，如果EM agent 版本在12.1.0.4 or 12.1.0.5以后， 或是EM 13C 建议使用perl 脚本的卸载方式
$<AGENT_HOME>/perl/bin/perl
<AGENT_HOME>/sysman/install/AgentDeinstall.pl -agentHome <AGENT_HOME>
