PRET Members Generated By Pretedit.txt

The Pretedit.txt file creates the partitioned data set (PDS) on the z/OS host that is used for PRET processing. The members in this PDS perform a number of tasks, for example, listing the tables that contain CLOB columns, gathering information required for key processing, and deleting rows in specific tables. Data sets are generated for each upgrade path.

The following table shows the data set members created by the Pretedit.txt file, the objects amended by these members (the SQL statement that is run is contained in the member) and the upgrade path for which these members are generated.

PDS Member Name	PRET Object Affected	SIA Upgrade Paths
PRETLDIN	S_DOCK_TXN_LOG	All
