Verifying and Backing Up the Encryption Key

Enterprise Manager uses an encryption key called emkey (or emkey.ora file) to encrypt and decrypt sensitive data, such as passwords and preferred credentials, which are stored in the Management Repository. The emkey is originally stored in the Management Repository, but is removed from there and copied to the Credential Store at the time of installation. Verify that the emkey is configured properly, and also back it up to a host different from the OMS host.

Step 1: Verify the emkey Configuration Step 2: Back Up the emkey Configuration

Step 1: Verify the emkey Configuration	Step 2: Back Up the emkey Configuration
Verify if the emkey is configured properly. To do so, run the following command: `$<OMS_HOME>/bin/emctl status emkey` If it is configured properly, you will see the following message: Oracle Enterprise Manager 12c Release 2 Cloud Control Copyright (c) 1996, 2011 Oracle Corporation. All rights reserved. The EMKey is configured properly. If it is configured properly, but not secure, then secure it. To do so, run the following command: `$<OMS_HOME>/bin/emctl config emkey -remove_from_repos`	Enterprise Manager automatically creates a backup of the emkey in the following location. Navigate to this location. `$<OMS_HOME>/sysman/config/emkey.ora` Copy the file to a host different from the OMS host.
