High Availability, Backup, and Recovery - Expert Oracle Enterprise Manager 12c - page 467

Users can now access the server by using the virtual hostname https://slb.example.com . Port 443 is the default
HTTPS port, so it is not necessary to specify the port number. If another port is selected as the secure port, it should
be specified as part of the URL. Any agents that were previously deployed and configured to upload to the physical
hostname of the OMS will be required to be resecured also. Use the following command to resecure the agents:
emctl secure agent -emdWalletSrcUrl https://slb.example.com:4899/em
After securing the agent, check the status to verify that it is uploading to the SLB Upload port by checking the
REPOSITORY_URL property.

Agent is Running and Ready
Likewise, if EMCLI was previously configured, it also needs to be reconfigured to use the SLB:
emcli setup -url= https://slb.example.com/em -username=sysman
Additional OMS Installation
The next step is to install additional management services. This can be done by using either the Add Additional OMS
Deployment Procedure (recommended) or Silent Mode. See the Oracle Enterprise Manager Cloud Control Advanced
Installation and Configuration Guide for details on using Silent Mode installation.
