Hi,
I was asked to test one Image copy job and the only modification i see between present job and existing job is the parameter passed to UID for DSNUPROD
Code:

//SURYA07 EXEC DSNUPROD,SYSTEM=DSN,UID='XXXXXXX',SORTPRI=0,TIME=90,


Can any one please explain the signiicance of this parameter, what is the possable impact by changing this parameter value.

KariSurya,

UID is for 'Utility ID'. To uniquely identify an DB2 utility, when multiple utilities are running at the same time.

If UID is not specified, it will be your userid.jobname.

Consider it as "identifier", as Sushanth said, this specifies the unique identifier for your utility job. You can use any string "to be used" as UID; only thing to keep in mind is that the maximum name length for it is 16 characters.
