Error while trying to retrieve text for error ORA-01019

Solution 1:

Well,

Just worked it out. While having both installations we have two ORACLE_HOME directories and both have SQAORA32.dll files. While looking up for ORACLE_HOMe my app was getting confused..I just removed the Client oracle home entry as oracle client is by default present in oracle DB Now its working...Thanks!!

Solution 2:

Correct the ORACLE_HOME path.

There could be two oracle clients in the system.

I had the same issue, the reason being my ORACLE_HOME was pointed to the oracle installation which was not having the tns.ora file.

Changing the ORACLE_HOME to the Oracle directory which is having the tns.ora solved it.

tns.ora lies in client2\network\admin\

Solution 3:

WHEN ORA-01019 ERROR OCCURS

  1. Check with TNSPING , if not responding then add Service Name entry in tns.ora file.
  2. Check firewall, if enabled then disable it.
  3. Add Env. variable ORACLE_HOME to the Path of oracle client directory up to 'c:\oracle...\client1', this solution will definitely work.
