REMOVE OEM 12C AGENT MANUALY

OEM 12c has a very useful Perl script which allows removing an installed OEM agent in the host. The process is quite straightforward just by invoking the AgentDeinstall.pl script located under:

$AGENT_HOME/sysman/install/AgentDeinstall.pl

[oracle@DB1 ~]$/u01/app/oracle/product/agent12c/core/12.1.0.3.0/perl/bin/perl  /u01/app/oracle/product/agent12c/core/12.1.0.3.0/sysman/install/AgentDeinstall.pl -agentHome /u01/app/oracle/product/agent12c/core/12.1.0.3.0


 Agent Oracle Home: /u01/app/oracle/product/agent12c/core/12.1.0.3.0


NOTE: The agent base directory: /u01/app/oracle/product/agent12c will be removed after successful deinstallation of agent home.
