Autoconfig on FE node fails with TNS error

Post date: Aug 26, 2010 3:42:40 PM or was failing with the below error even though the listener is running in the db server

ORA-12541: TNS: no listener

You may further notice that it is trying to connecto to DB via a different port# whereas the DB listener is running on a different port#.

Well, the reason for your problem is the database context file was not updated with the new port# and hence the Autoconfig on FE node was erroring out.

Please do the following steps to rectify the error:

• Update the context file on db node with the original port# and run Autoconfig.

• Then run the Autoconfig on FE node which will complete successfully.
