Connection issue

[phronima]

I've installed Oracle 11Xe, and PL/SQL developer. That was fine.

Then I installed Oracle Developer Tools togeter with the ODAC into a different home. Now PL/SQL doesn't work with either homes.

On the original XE home it gave me a ORA12154 error. On the other I have the ORA 12560 error.

I am new to Oracle, so this is way confusing. Any help appreciated.

I should mention all of 11xe, PLSQL developer and the 11.2 ODTODAC32 are on the one machine.. Thanks in advance

Maybe you should look up "TNS File" in Help/Support Info..., and check if that file is correct.
