    <...>
    [OK]

Cause

There are several possible causes for similar errors:

  • Scenario #1 (likely) - Invalid cache files in end user's Windows profile
  • Scenario #2 (rare) - Incorrect database connection nomenclature used
    • Specifically, Oracle database connection settings are incorrect.

Resolving The Problem

Scenario #1 (likely)- Invalid cache files in end user's Windows profile
Clear the end user's cache files.

  • TIP: For instructions, see separate IBM Technote #1516661.

Scenario #2 (rare) - Incorrect database connection nomenclature used
Modify the data source connection (in Controller configuration) to refer only to the Oracle SID (as defined in the Oracle tnsnames.ora file) and not SERVERNAME/SID.
  • TIP: For instructions, see separate IBM Technote #1574732.
