Hi All,

If any one of you knows about Service Request Block(SRB) and Task Control Block (TCB) in terms of CPU time.

Thanks.

Hi You,

It's been a long time , but as I recall TCB time is the total time charged ly to the task that used the CPU directly (your pgm); SRB time is the time used by system functions (I/O requests, subpgm loads, etc.) at the request of the TCB task (your pgm).

Combined they represent the total CPU time used to exec the jobstep.
