TNS-00026:

INTCTL: TNS_ADMIN directory set, and is being used
Cause: The TNS_ADMIN environment variable is set properly. INTCTL will use the TNS_ADMIN directory. This is only an informative message. If you do not want it to be used, and want the default directory to be used instead, then unset TNS_ADMIN and reexecute.
Action: None.
