You can run this script to fix issues after the database upgrade is completed. The postupgrade_fixups_ pdbname.sql (for PDBs, where pdbname is the name of the PDB) or postupgrade_fixups.sql script (Non-CDB databases). The preupgrade_fixups_ pdbname.sql (for PDBs, where pdbname is the name of the PDB) or preupgrade_fixups.sql script (Non-CDB databases).īefore you run the upgrade, you can run the preupgrade fixups script manually in SQL*Plus to resolve many of the issues identified by the preupgrade tool. ![]() ![]() ![]() The log file contains the output of the Pre-Upgrade Information Tool.
