Create Product Parameter File (PPF) Override

This section provides information to help you create a product parameter file (PPF) override. The example used in this section shows how to change the shared file system (SFS) file pool where the product installation files reside.

You must never modify the product supplied ZVMB036A $PPF or ZVMB036A PPF files to change the file pool name or any other installation parameters. If the ZVMB036A $PPF file is serviced, the existing $PPF file will be replaced, and any changes to that file will be lost; by creating your own $PPF override, your updates will be preserved.

The following process describes changing the default file pool name, VMSYS, to NEWPOOL.

This section contains the following topics:

Step 1. Create a new $PPF override file.

Step 2. Allocate the SFS Directories

Step 3. Continue with the Product Installation

Step 1. Create a new $PPF override file.

Create an override file manually, or use an editor or the Make Override Panel function. Respond to the VMFINS INSTALL prompt during the installation of the product.

Create or modify the variable declarations area (:DCL) so it looks like the following sample.

************************************
* VM:Backup - SFS install   	 *
************************************
:OVERLST. VMBACKUPSFS
:VMBACKUPSFS. VMBACKUPSFS ZVMB036A

:END.

Create the $PPF Override file on the Software Inventory Minidisk at file mode letter D. To create the usable PPF file from the $PPF file, compile your changes.

VMFPPF overname VMBACKUPSFS

overname

Defines the name of your override file.

Step 2. Allocate the SFS Directories

Use the ENROLL command to allocate an SFS file space for the owner of the directories and then issue a CREATE DIRECTORY command to create the directories named in your PPF Override file.

Allow the VMANAGER user ID to write into the directories by issuing the GRANT AUTHORITY command for each directory, with the attributes WRITE and NEWWRITE.

Note: For more information about the use and format of the commands ENROLL, CREATE DIRECTORY, and GRANT AUTHORITY, see IBM SFS documentation.

Step 3. Continue with the Product Installation

Restart the product installation in the chapter Installing Product Materials at step 1.3 by issuing the VMFINS command with the PLAN option. In that step, and in subsequent steps, use the name of your PPF Override file wherever the ppfname is present in the install commands.
