Hi,

In this statement
Code:
//SYSOUT   DD  SYSOUT=Y

I understand 'Y' designates a special class while in
Code:
//SYSOUT   DD  SYSOUT=*

SYSOUT class would be defaulted to the respective LPAR.

My concern is, if I used "Y", how differently the system would treat it ?

Can I say, if "Y" is designated to Production classes, then the DASD used for system output in production would be little costlier than a test DASD ? (might be dumb assumption but any how I come up with this thought, Please suggest.)

Hi Anuj,

SYSOUT classes are site dependent.

A '*' for SYSOUT class indicates that the class given by the
MSGCLASS= parameter on the job statement is to be used for
this SYSOUT DD statement, so that all the job's SYSOUT will
go to the same output class.

I'm not aware of any intallation where different DASD is used for different output class.

Hi,

In this
Code:
//SYSOUT   DD  SYSOUT=Y

usually, this type of SYSOUT parameter names the output class to which the printed output belongs or the forms on which the data set is to be printed.

My concern is in case it's (Y) dedicated to some DASD, does that mean that DASD is costlier just because it's in service of Production class..?

Probably not.

And different classes could mean different handling - at the shop I am now, one class is routed into the sysout repository and kept for far longer than it would being left on the JES spool.

I guess it's a case of talking to the people that set it up.
