The postupgrade fixup scripts are generated when you run the Pre-Upgrade Information Tool (preupgrade.jar). Run the postupgrade scripts any time after completing an upgrade. For Non-CDB databases, the postupgrade fixup scripts provide general warnings, errors, and informational recommendations.

You can run the script either by using the catcon.pl utility, or by using SQL*Plus.

The location of the postupgrade SQL scripts and log files depends on how you set output folders, or define the Oracle base environment variable. The postupgrade fixup scripts are placed in the same directory path as the preupgrade fixup scripts.

If you specify an output directory by using the dir option with the Pre-Upgrade Information Tool, then the output logs and files are placed under that directory in the file path /cfgtoollogs/dbunique_name/preupgrade, where dbunique_name is the name of your source Oracle Database. If you do not specify an output directory when you run the Pre-Upgrade Information Tool, then the output is directed to one of the following default locations:

• If you do not specify an output directory with DIR, but you have set an Oracle base environment variable, then the generated scripts and log files are created in the following file path:

  Oracle-base/cfgtoollogs/dbunique_name/preupgrade

• If you do not specify an output directory, and you have not defined an Oracle base environment variable, then the generated scripts and log files are created in the following file path:

  Oracle-home/cfgtoollogs/dbunique_name/preupgrade

The postupgrade fixup scripts that the Pre-Upgrade Information Tool creates depend on whether your source database is a Non-CDB database, or a CDB database:

• Non-CDB: postupgrade_fixups.sql

SQL> SPOOL postupgrade.log
SQL> @postupgrade_fixups.sql
SQL> SPOOL OFF
