Recently I had to change OID port (Non-SSL and/or SSL Port) in EM | Server Properties. for one requirement. After bouncing Managed Server and OPMN services, when I tried checking the port information in EM console, I recieved Failed to load server configuration. Check the Internet Directory Server logs. Possible Error: “hostname:port”. FMW control was accessing the OID instance on a wrong / incorrect port.
The cause of the issue is that we must update the registration of an OID component in a registered Oracle instance whenever changing any of the following configuration attributes:
Solution to resolve above issue is:-
Update ports using opmnctl command shown below to match the Port Numbers in “Port Usage”
$ORACLE_INSTANCE/bin/opmnctl updatecomponentregistration -adminHost oraworld.co.uk -adminPort 7002 -adminUsername weblogic -componentType OID -componentName oid1 -Port 4060 -Sport 4131
Stop, then Start OID1 component from within EM; Now Load “Administration->Server Properties” from drop down menu, and change the ports to your Non-SSL and SSL Ports.
