Deinstalling in Silent Mode Using AgentDeinstall.pl Script

To deinstall a Management Agent in silent mode using the AgentDeinstall.pl script, follow these steps:

1. Invoke the AgentDeinstall.pl script:
   $<AGENT_HOME>/perl/bin/perl <AGENT_HOME>/sysman/install/AgentDeinstall.pl -agentHome <AGENT_HOME>
   For example,
   $/u01/app/Oracle/core/12.1.0.1.0/perl/bin/perl /u01/app/Oracle/core/12.1.0.1.0/sysman/install/AgentDeinstall.pl -agentHome /u01/app/Oracle/core/12.1.0.1.0/
2. Manually remove the targets, which were being monitored by the Management Agent you deinstalled, from the Enterprise Manager Cloud Control console.
