5. Filter steps

This step runs filtering routines against the content of the upgrade instructions. The results of this step are used in determining what steps to display in the tool, and what steps to suppress or mark as automatically completed.

If the following message will appear in the log information "Found that at least one of Student Systems, Student Recruiting and/or  Financial Aid products is installed! Setting this project back to  DATA COLLECTION COMPLETE to prevent continuation of this upgrade.", only in a test environment you can force to fix the error by updating the fnd_product_installations table:  

update fnd_product_installations set status = 'N' where application_id in (8406, 8405);

commit;

If this step complete successfully, you will see the following message at the end of the log information:

Checking to see if Student Systems or Student Recruiting are installed...
Neither Student System nor Student Recruiting are installed.
It is safe to proceed with the Release 12 upgrade.
Successfully performed all filtering routines.

6. Generate patch list and dynamically create pre-upgrade patching steps

This step loads only relevant patches into EOF_REQUIRED_PATCHES, based on the upgrade from version and the product filter built in a previous step. It then queries the Applications database to determine the list of patches which have already been applied and flags the appropriate records in EOF_REQUIRED_PATCHES, by updating the APPLIED_FLAG. Finally, it dynamically generates steps in the 11i Pre-Upgrade Category for downloading, merging and applying those patches.

This step will contains in the log information the following message:

Creating 1 merge step(s).
Creating the Compilation step.
Creating the Verification step.
PL/SQL procedure successfully completed.
Completed execution of eof17208e.sh.
