DATABASE PATCH SET UPDATE 12.1.0.2.170117 apply fails – catconInit failed, exiting

Last weekend was patchday. The goal was to apply the patch 24732082 (DATABASE PATCH SET UPDATE 12.1.0.2.170117) to a 12.1.0.2 database on AIX. The OPatch precheck returned no error and OPatch apply was ok. The problem was the post step, the datapatch command failed with the message catconInit failed, exiting.

The solution was described in this My Oracle Support Note: Datapatch fails with “catconInit: database is not open on the default instance” (Doc ID 2003488.1)

In the glogin.sql file  located in ORACLE_HOME/sqlplus/admin were two lines:

After I have commented out these lines, everything runs ok.

Summary: Two small lines, a big impact.
