Configure Oracle Configuration Manager Manually After Enterprise Manager Installation

During Enterprise Manager 13c Release 4 installation process, Oracle Configuration Manager (OCM) setup is optional and done through My Oracle Support Details screen.

If there is no connectivity to ccr.oracle.com when providing My Oracle Support credentials for OCM configuration, you will get exception errors similar to the following:

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError:

...

To avoid the errors, do not provide your My Oracle Support email address or My Oracle Support password when you get to the My Oracle Support Details screen and configure Oracle Configuration Manager later.

After the Enterprise Manager 13c Release 4 installation process completed, you can configure Oracle Configuration Manager manually by running the following on each OMS instance:

Stop OMS
Run setupCCR /configCCR without ORACLE_CONFIG_HOME environment variable set:
For Linux: $ORACLE_HOME/oracle_common/ccr/bin/setupCCR /configCCR -a

For Windows: $ORACLE_HOME/oracle_common/ccr/bin/setupCCR /configCCR.exe -a
Start OMS
