SQL error during rules upgrade process



When running an upgrade from PRPC 6.x to Pega 7.x, the upgrade fails with the below error in the upgrade logs during the rules schema upgrade.

Error Messages

[java] WARNING: Failed to execute SQL in file oracledate02760.sql
[java] Throwable occurred: java.sql.SQLException: ORA-30556: either functional or bitmap join index is defined on the column to be modified

[java] WARNING: Statement: ALTER TABLE RulesSchemaName.pr4_rule_vw MODIFY pxInsName VARCHAR2(193)

Steps to Reproduce

Upgrade the Rules schema.

Root Cause

A defect or configuration issue in the operating environment.  A functional index is defined on column RulesSchemaName.pr4_rule_vw.pxInsName.  A functional index on a column stops Oracle from altering its type or length.


Make the following change to the operating environment:

1) Revert to the backup taken before starting the upgrade.
2) Drop the functional index on column PEGA_RULES.pr4_rule_vw.pxInsName.
3) Run the upgrade again.
