Hi,
I have a program A which calls Program B and that inturn calls PROGRAM C .

Code:


 PROGRAM A ---> PROGRAM B ----> PROGRAM C


So can i get the total execution time of each called programs PROGRAM B and PROGRAM C.Is there any field stored in the statistics to retrieve the information from.


Please help me out.

Talk to your performance and capacity people, if it's possible they will have done it.

Hi,
I am not sure But I think if you have Strobe, Then that will give details of the time taken by a called program.

In the absence of STROBE, SMF is your best source of data about the program and its execution statistics. Ask your performance and capacity team to provide the details as this is something that they would get by analysing from the SMF data produced, as expat has also pointed to.

Don't forget that as a rule of thumb, 60-80% of your processor resources consumed by the task are usually spent outside the application code, establishing and maintaining the runtime environment, or in database access interface.

If you want a relative measurement of what code gets executed the most time, you might do with execution counters in test tools like Xpediter.

You should also be able to calculate if it matches the expected numbers for the problem data used.
