After upgrade from 6.2 to 7.2, displays 6.2 login credentials



After an upgrade from PRPC 6.2 SP2 to Pega 7.2, including a schema split, the engineer who was conducting the upgrade was attempting to follow the additional steps to perform the Optimize Schema in order to remove duplicate tables.

However, when they navigate to Designer Studio > System > Database they could see no Optimize Schema option.

The engineer had already confirmed that their prconfig.xml contained the following entry:

<env name="database/AutoDBSchemaChanges" value="true" />

Error Messages

Not Applicable.

Steps to Reproduce

Not Applicable.

Root Cause

The system will use the pxViewAndOptimizeSchema When rule to determine whether the Optimize Schema landing page should be displayed.
This in turn will check for the database/AutoDBSchemaChanges value and the ViewAndOptimizeSchema privilege to decide whether to display that option.

Further examination of the ViewAndOptimizeSchema privilege showed that this had a privilege level of 2 for the role that was associated with the operator.
However, the current Production Level was set to 3. Hence disqualifying that landing page from being displayed.


In order to overcome the problem the Production Level was temporarily changed to two and the system restarted.
After this the Optimize Schema landing page was available.
