    Sql Developer -  ORA-12705: Cannot access NLS data files or invalid environment specified

    asimshafi

      I am using Sql developer to connect Oracle databases, I am able to connect most of the Oracle database instances but I am not able to connect one instance (12c) and I get the following error.

       

      Note: I didn't have oracle client instance at my laptop, I just have Sql developer, which is fine for most of the Oracle instances.

      DBA are also not able to figure out what is the issue?

       

      Status : Failure -Test failed: ORA-00604: error occurred at recursive SQL level 1
      ORA-12705: Cannot access NLS data files or invalid environment specified

       

      I am able to connect to following databases.

      Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

      Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
