Hi,

We have 8 Libraries under JOBLIB in every Job. Say,

HLQ.MLQ.LOADLIB1
HLQ.MLQ.LOADLIB2
HLQ.MLQ.LOADLIB3
HLQ.MLQ.LOADLIB4
HLQ.MLQ.LOADLIB5
HLQ.MLQ.LOADLIB6
HLQ.MLQ.LOADLIB7
HLQ.MLQ.LOADLIB8

If we have a program A in a Jcl and its loadlib is present in LOADLIB1, will the otherlibraries also be searched?

For every execution of a Program, will all the 8 libraries be searched?

Can some one explain the flow of execution? And also let me know the time/cost it takes to search one library?

Thanks

The time/cost is site specific and depends on the CPU and pricing rules.

Arvind,

I am not sure if got answer to your first question in the link taltyman provided. The answer is no, if it is in LOADLIB1 then it will not search any other library.
