CICS VT subtasking

Batch programs that do not contain SQL do not require subtasking. Batch programs that do contain SQL might require subtasking, based on the following factors:

The following example demonstrates when to use CICS® VT subtasking and what the results are.

Assume that you have an application program that updates two VSAM data sets called FILEA and FILEB. These data sets have been migrated to DB2 tables called VID_TABA and VID_TABB using CICS VT. The application program also contains SQL calls and updates a DB2 table called SQL_TAB. The program issues DB2 commit calls at certain intervals. The effect of these commit calls depends on whether CICS VT subtasking is being used or not.
