Question

Upgrade Application Schema Wizard generates DDL that includes changes to internal columns

After upgrading to from Pega 7.3 to Pega 8.3, the generated DDL from the post upgrade step "Upgrade Application Schemas" is including alterations to several internal Pega properties. Examples include:

... MODIFY PZINSKEY VARCHAR2 (512 CHAR)

... MODIFY PYMEMO VARCHAR2 (512 CHAR)

... MODIFY PYLABEL VARCHAR2 (128 CHAR)

... MODIFY PXOBJCLASS VARCHAR2 (128 CHAR)

... MODIFY PXRULEACTION VARCHAR2 (128 CHAR)

... MODIFY PXRESOLUTIONCOSTDELTA NUMBER (38, 3)

I would like to understand the cause for the increase in column lengths before proceeding with the DDL changes. Any feedback appreciated.
