Steps to Reproduce

Not Applicable

Root Cause

A defect in Pegasystems’ code or rules.


Perform the following local-change:
Follow the instructions below to clean up your system of old rules and shrink the pr_index_reference table.

1. Use the cleanup.bat/ script available in the ../scripts dir of each the media to generate SQL that deletes all of the old PRPC rules. All rules prior to the current major release will be deleted. The generated script can be cut and pasted into SQL dev. An example is included below.

2. Using SQL dev or a similar application, run the generated script to delete the old PRPC rules. Issue the commit command after the deletion.

4. Truncate the <rules schema>.pr_index_reference table and rebuild all indexes for this table. See example below
- truncate table <rules schema>."PR_INDEX_REFERENCE";
- alter index <rules schema>."INDEX_REFPORT" rebuild // do this for each index

5. Rebuild the pr_index_reference table using prpcUtils. PrpcUtils is a script available with every build and can be found in the ../scripts dir.
- In the .../scripts dir update the file.
- Set the DB connection and schema details as appropriate for your system. See example below
- Update the "Settings for Expose Tool" section to include the Rule- class and its descendants. See example below.
- Run prpcUtils.bat or with the expose option - For example. prpcUtils.bat expose
This will resave all of the rules in the system triggering a rebuild of the pr_index_reference data. This will take about 30 minutes.

6. Rebuild the stats on <rules schema>.pr_index_reference table.
