I would like to tune my COBOL program., It would be helpful for me if I could know these terms.

Generally, the two times are calculated as:

TCB - time spent executing your program logic
SRB - time spent on system functions on your behalf

Tuning your program can reduce TCB time. Save SRB time by using large blksizes to reduce the number of I/O operations, etc.
