Use one of three methods to check the state of the Oracle Data Dictionary for diagnosing upgrades and migrations.
dbupgdiag.sql script collects upgrade and migration diagnostic information about the current state of the data dictionary.
You can run the script in SQL*Plus both before the upgrade on the source database, and after the upgrade on the upgraded database as the SYS user. Refer to My Oracle Support note 556610.1 for more information about using the
dbupgdiag.sql script to collect upgrade and migrate diagnostic information.
Running a SQL Query on DBA_REGISTERY
To show the current state of the dictionary, perform a SQL query similar to the following example:
SQL> spool /tmp/regInvalid.out SQL> set echo on -- query registry SQL> set lines 80 pages 100 SQL> select substr(comp_id,1,15) comp_id,substr(comp_name,1,30) comp_name,substr(version,1,10) version,status from dba_registry order by modified;
Running a Query to Check for Invalid Objects
To query invalid objects, perform a SQL query similar to the following example:
SQL> select owner, object_name, object_type from dba_invalid_objects order by owner, object_type;
After you have upgraded the database, and you have run
utlrp.sql, this view query should return no rows.
