Recently I was working with Automation team, where the requirement is to discover & promote oracle databases to OEM13c using with silent installation where no -MAN EMDBA needs to add those targets manually in OEM. Initially I thought it could be quite challenging but later on after familiarizing the EM CLI I have created perl script which can discover & promote targets directly into your ADMIN_GROUPS in OEM13c.

1. Install EM CLI on the Oracle Database server.
2. Update the below scripts which appropriate the passwords & directory locations.
3. This script has Error handling codes which Chef/puppet automation tools required.

Set your env to EMCLI and run below script.
For Example we are promoting TEST01 database on dbadeeeds servers to OEM13c into LifeCycle property=Development & Department=Dev_Dal

bin/perl discover_promote.pl dbadeeds.systems.com TEST01 Dev Dev_Dal promote
