z/OS System Libraries, Parmlib

Green check Please! Verify all details or suggestions with the appropriate vendor and / or vendor's manuals.

Control Parameters

You can simplify the installation process by specifying system defaults in members (IKJTSOxx) of the SYS1.PARMLIB data set instead of in tables. Using SYS1.PARMLIB members makes it easier to customize a system because installations need to change only one file. If you use tables, you must save them from one release to the next, and you must reassemble and link-edit them every time you make updates.

You can use SYS1.PARMLIB member IKJTSOxx to specify TSO/E system defaults for:


Installation-written TEST subcommands

TSO/E commands that run under the TEST command

Authorized commands and programs

Commands that users cannot run in the background

Commands and programs eligible for command or program invocation platform processing

The broadcast data set name because SYS1.BRODCAST is no longer the only broadcast data set name allowed

|The password because up to 255 bytes are allowed to set for |the LOGON password

To simplify the creation of the PARMLIB members, SYS1.SAMPLIB contains samples that a system programmer can copy to SYS1.PARMLIB and then change to suit the needs of the installation. For example, the IKJTSO00 member of SYS1.SAMPLIB contains samples of the statements you can use in the IKJTSOxx member. The changes to SYS1.PARMLIB take effect at the next IPL, or when you use the PARMLIB command.

What is PARMLIB?

Parameter Library. A dataset in z/OS containing parameter settings. The most important is SYS1.PARMLIB which contains parameter settings for z/OS and many key subsystems.
IBM ships 3 PARMLIBs:


SYS1.PARMLIB is no longer is required on the 'SYSRES' DASD if using the SYSn.IPLPARM data set. Go to SYSn.IPLPARM
You now can have as many "PARMLIBs" as you require.
