In the load step using DSNUTILB, we are specifying the system and uid.

The following is an example of load step.

//STEP010 EXEC PGM=DSNUTILB,REGION=9M,
// PARM=(DBT1,temp,'')
...........
...........

Here what is temp?Can i get more information on this uid(temp)....
I would like to know how it is created?if i get more information on DSNUTILB it would be so helpful.

the second parameter ( "temp" in your example ) is the utility-Id.
It is needed to adress a specific utility ( e.g. if you want to alter, terminate or restart it ).

If you provide a value, that value is used.
If you omit it or use an empty string, "userId.jobname" is used as default

Hi,
Thanks for your response.....
I have one more doubt regarding the utility..I dont have DBA permission but still i would like to know how can we create the utility(Temp in teh above example) or how can we view it?

Since i am new to using DSNUTILB i dont have much idea on these utilities.

You can't "create" an utility.

You can submit a job containing an EXEC PGM=DSNUTILB step.
If you do, an utility is started and the specified ( or default ) utility-ID is assigned to it.

you need some authority to start the utility ( not neccessarily DBADM, may also be LOADAUTH , REPAIRAUTH or something like that ) but you may use any valid utilityId ( if it's not currently assigned to another utility ).

Then what is the third parameter say PARM=(DBT1,temp,'')? Can i get more information on other parameters for DSNUTILB if any?

You could always try looking in the utility guide and reference manual.

with the third parameter you specify, whether you want to start a new utility or you want to restart a stopped utility.

As dav1mo mentioned, look at the manuals for detailed information
