When you create the data store tables, you have two options. You can either choose that WebSphere® Application Server does it automatically, or that the database administrator does it manually.
For example, changing the value of the RETVLCFK DB2 parameter from NO to YES might introduce padded values.
For more information about the RETVLCFK parameter, see VARCHAR FROM INDEX field (RETVLCFK subsystem parameter) in the DB2 information center.
