Hi,
I ran strobe on a program and got a strobe report that shows a cobol library module called IGZCSH1 taking about 19% of CPU time. I read in an IBM site that this module is invoked when SEARCH ALL is used but no specific information on this module was given. Can anyone help pls?

.COBLIB IGZCPAC IGZCSH1 COBPACK GENERAL .88 19.40

Cheers,
Subzero

Subzero,

How big is the table being searched? Is the search defined the same as the table key? Is the table intialized to high-values before loading ?

Dbz,

I am not sure if that link is applicable in this case.

kolusu,

you are correct. I assumed that the OP had

made the table ODO if it was large
attempted to sort the input triggers which would allow a check of last found in an attempt to avoid a search
was perfoming somany tasks in the run-unit that 1/5 of the time spent on table look-ups was abnormal since we don't have any idea what is going on the other 81% of the time

having been given no idea of what the program was doing, I felt it easier to point to a possible APAR fix, though the OP did not indicate anything that reflected the write-up.

I apologize to Subzero for sending him on a probable wild-goose-chase, since I felt he had sent us on one.
