Important FAQ for EBS Data Model Comparison Report

1)In IE, when I open the “DataModelComparisonReport.html”, I am seeing a yellow bar for running scripts and ActiveX controls. what is this for?

You are prompted for permission to allow the download of ActiveX controls. Click on the yellow bar and select ” Allow Blocked Content” and then click “Yes” on the confirmation dialog. This will allow you to enable ActiveX controls which is required for rendering the report.

2) I am getting a message saying “Product:<prod>is removed in <release>” or “Product:<prod>is added in <release>”.

New or removed products (i.e. a product didn’t exist in the source release but exist in the target release or vice versa) are not considered for comparison because all the objects would be all new in the target release or removed from. The data model comparison report is available only for products that exist in both releases except for 11i IRC and AME products.
3) In 12.2 (and onwards) report, I see a checkbox to include data model changes that support Online Patching[3] . What are those changes?


E-Business Suite Release 12.2 introduces several major new technologies and updates. One of the features is Online Patching, which enables patches to EBS 12.2 to be applied while the system is running. To support the Online Patching feature, there are thousands of automated data model upgrades made during the “online patching enablement” process as part of the EBS 12.2.0 upgrade. Even though these changes are “valid data model changes”, they are not “interesting data model changes” and are filtered out from the report. However, if you want to review the complete data model changes including the automated data model upgrades, you can select the checkbox located in the top of the report.

FYI. The data model changes to support Online Patching include but not limited to:
1.New ZD_EDITION_NAME column with default value is added to seed data tables.
2.New ZD_EDITION_NAME column is added to all unique indexes.
3.New Editioning Views (called TABLE_NAME#) are added for regular tables.
4.New triggers (called TABLE_NAME+) on the Editioning View are added.
5.Trigger’s base object type and name are changed to refer the editioning view instead of the direct table.
6.User Defined Types that are referenced by tables are moved to the APPS_NE schema.
7.Table columns based on User Defined Types now reference the type in APPS_NE schema.
8.Synonyms that pointed to ordinary tables now point to the editioning view instead.
9.Columns for regular tables are revised via new physical columns (called COLUMN_NAME#<n>; where <n> is a revision tag).
10.Global temporary tables are revised via new physical global temporary tables (called TABLE_NAME<n>; where <n> is a revision tag).
