Stored Outlines and SQL Profiles do not work well with PeopleSoft. Bind variables in Application Engines often become literals before the SQL statement is submitted to the database, unless the ReUse Statement feature has been enabled, which it is not by default.
I wrote about this in PeopleSoft for the Oracle DBA, it contains a script called stmtid.sql (listing 11-23, page 280) that adds an identifying comment to each of the stored statements used by PeopleSoft COBOL programs.
Now, I have produced a similar script for Application Engine programs. The script aeid.sql adds identification comments containing the name of object. It directly modifies the PeopleTools tables for Application Engine steps and PeopleSoft SQL objects. These comments will be seen in database tools and traces. So now when your database tools find a problem statement, it is easy to find the source.
Below, is part of a screen shot from Oracle Enterprise Manager. You can see the identifying comment in the SQL, which was added by this script
The comment identifies the name of the Application Engine program, section, step and step type. In this example, the SQL is from an Application Engine ID GPGB_EDI_PRC, in section called EDI_PRC, in a SQL type step called Step01.
For example, if you need adjust this SQL statement, perhaps add a hint to it, you don't have to spend time working out where it came from. It is not uncommon to find many similar SQL statements in a program. Also, where dynamic code is used to generate the SQL statement, it can be very tricky to find the exact source.
- You will need to edit the script each time, to specify which Application Engine programs and SQL objects are to be commented. The script is not perfect. It does not handle some very long statements, so you cannot simply instrument the entire system in one go.
- The script is designed to run in SQL*Plus.
- It produces a report of statements that it has altered.
- The script does not commit. You should either commit or rollback the update depending upon whether you are satisfied with the output.
- I suggest that the script only be run in pre-production environments. The comments will of course be migrated along with any other changes.
