Well, I have written a pl/sql function that generates the TNSNAMES file, it needs to be run as a DBA and you have to create the $ORACLE_HOME/network/admin directory, but it works rather well. It uses a dblink to a central database that has a table with all the info of all the databases and a table that says which database should be included in the tnsnames of each server... it's a bit boring to set up, but once it's up an running it's just a call to a pl/sql procedure to modify the data. I've also created an APEX interface for this package... perhaps you can take your time and do it as well... in the long run it saves a LOT of time. Regards.

This is a multi location within and outside the US and managing TNSNAMES.ORA files is well a PAIN. I'm especially interested in anyone who has or is using TnsManager from Andrew Barry (http://www.shutdownabort.com/tnsmanager/ <http://www.shutdownabort.com/tnsmanager/> ), especially with regard to support.
