VNI-4026 : Discovery failed : Error while transferring services.ora from agent : 4009.

I am BACK after a LOOOOOOONG break...!!

I was not able to update my blog all these days but not anymore..Anyways,let me come to the point..

We have been migrating databases from one datacenter to another..Migration of the databases were pretty simple..Just take the cold backup of the database and restore it.We had to build a new server for the migration and the Unix consulatnt had installed the Oracle for us on the new server..Actually,he had not installed Oracle as such..He copied the Oracle home from the old server to the new server.Since the volumes on the server were identical,we had no issues in bringing up the database on the other server.

But when we tried to discover the new server on the OEM,there was this error

VNI-4026 : Discovery failed : Error while transferring services.ora from agent : 4009.

The intelligent agent was up and running.We stopped the agent and started the Intelligent agent after deleting *.q files in $ORACLE_HOME/network/agent/ location.Even then we had the same problem.

The above issue got resolved only after REINSTALLING the entire Oracle Home on the new server.It is recommended not to copy the Oracle Home from one server to another.Some components may work and some may not!!So always go with the fresh installations while taking such kind of activities.
