During the upgrade from 11.2.0.4 to 12.1.0.2 we received an error.
In the created logfile located in /u01/app/oracle/cfgtoollogs/dbua/logs the following was reported:
UPGRADE_PROGRESS : 36%
XDB component upgrade error:
ORA-24328: illegal attribute value
When checking out the details in the /u01/app/oracle/cfgtoollogs/dbua/EDBA7_01/upgrade1/catupgrd0.log
It reports:
15:29:21 SQL> Rem Ensure that all XDB$RESOURCE dependencies are validated
15:29:21 SQL> Rem before any packages that depend on it are compiled below
15:29:21 SQL> desc XDB.XDB$RESOURCE_T;
ERROR:
ORA-24328: illegal attribute value
The problem seems to be caused by the fact the New Feature 12c, invisilbe columns
As we have set in the glogin.sql added: set colinvisible on
When you remove this line, the above error is not reported during the upgrade.
The problem seems to be reported in bug: 25602907
Hope this helps.
