Hi Friends,
We have more than 6 QA database's, and each time any new DB is up i need to make changes in all the QA database.I am planing to create a centralised location for tnsnames.ora file where in i just add in one location and all the 6 QA gets this reflected.Can any one help me in setting this up or help in getting DOC's on this.

I appreciate all ur help.
