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 ZVMN012A $PPF or ZVMN012A PPF files to change the file pool name or any other installation parameters. If the ZVMN012A $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.

Step 1. Create a New $PPF Override File
Create an override file either manually, using an editor, or use the Make Override Panel function when prompted by the VMFINS INSTALL command during product installation.
Create or modify the variable declarations area (:DCL) so it looks like the following sample.
************************************ * MANAGER - SFS install * ************************************ :OVERLST. <vmcomp2> :<vmcomp2>. <vmcomp2> <vmsesprodid> :DCL. UPDATE &LMODZ DIR NEWPOOL:<vmsesprodid>.LOCALMOD &APPLX DIR NEWPOOL:<vmsesprodid>.APPLYALT &APPLZ DIR NEWPOOL:<vmsesprodid>.APPLYPROD &DELTZ DIR NEWPOOL:<vmsesprodid>.DELTA &BLD0Z DIR NEWPOOL:<vmsesprodid>.TSYSTEM &BLD2Z DIR NEWPOOL:<vmsesprodid>.TADMIN &BLD4Z DIR NEWPOOL:<vmsesprodid>.TPUBLIC &BLD6Z DIR NEWPOOL:<vmsesprodid>.HELP &SAMPZ DIR NEWPOOL:<vmsesprodid>.SAMPLE &BAS1Z DIR NEWPOOL:<vmsesprodid>.BASE :EDCL. :END.
If your $PPF override file was not created on the Software Inventory Minidisk at file mode letter D, then move the file to that disk. Compile your changes to create the usable PPF file from the $PPF file.
VMFPPF overname <vmcomp2>
- 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.
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.
