An application programmer may notice multiple messages similar to the following written to the CICS //MSGUSR DD while stepping through code.
20:18:12 CTSREGION TERMID USERID VTAT SET TASK(nnnn)
20:18:13 CTSREGION TERMID USERID VTAT SET TASK(nnnn)
20:18:13 CTSREGION TERMID USERID VTAT SET TASK(nnnn)
What is the reason for all these messages and multiple VTAT task numbers?
Why are multiple VTAT transactions, each with a separate task number, executed while stopping at breakpoints and stepping through a program?
Monitoring a CICS program with InterTest for CICS release 11.
The VTAT transaction is used for handling breakpoints and a separate VTAT is created for each breakpoint.
A description of the VTAT transaction can be found under the IN25OPTS keywords (VTATT =) in the InterTest and Symdump r11.0 documentation
