Then re-run the OPMN Configuration Assistant - Start OCA.
F.3.19 WARNING: DCM service may not be available at this time
Problem
When installing the first node of an OracleAS Cluster (Identity Management), the Java
Security Configuration Assistant may return the following message:
WARNING: DCM service may not be available at this time to synchronize $ORACLE_
HOME/j2ee/home/config/jazn-data.xml file.
This is due to a failure in updating the DCM repository and could happen if your load
balancer virtual server is not configured to return immediately to the calling client
when the backend services to which it forwards traffic are unavailable.
Solution
Perform the following steps to correct the problem:
1. Run the following command after installation completes:
prompt> $ORACLE_HOME/dcm/bin/dcmctl updateConfig -ct jazn
2. Verify that the dcmctl updateConfig command did not return any errors.
3. Use the following command to verify that the password is correct:
prompt> $ORACLE_HOME/jdk/bin/java
-Doracle.security.jazn.config=./jazn/install/jazn.xml
-jar jazn.jar -checkpasswd jazn.com admin -pw admin_password
