See the following for information pertaining to your Enterprise Manager installation:


Use the following URL to access:

	1. Enterprise Manager Cloud Control URL: https://emtest.kr:7803/em
	2. Admin Server URL: https://emtest.kr:7102/console

The following details need to be provided while installing an additional OMS:

	1. Admin Server Host Name: emtest.kr
	2. Admin Server Port: 7102

You can find the details on ports used by this deployment at : /oracle/app/oracle/middleware/install/portlist.ini


 NOTE:
 An encryption key has been generated to encrypt sensitive data in the Management Repository. If this key is lost, all encrypted data in the Repository becomes unusable. 

 A backup of the OMS configuration is available in /oracle/app/oracle/gc_inst/em/EMGC_OMS1/sysman/backup on host emtest.kr. See Cloud Control Administrators Guide for details on how to back up and recover an OMS.

 NOTE: This backup is valid only for the initial OMS configuration. For example, it will not reflect plug-ins installed later, topology changes like the addition of a load balancer, or changes to other properties made using emctl or emcli. Backups should be created on a regular basis to ensure they capture the current OMS configuration. Use the following command to backup the OMS configuration:
/oracle/app/oracle/middleware/bin/emctl exportconfig oms -dir <backup dir>
