Preventive service planning (PSP) information contains
the latest information that is applicable to your hardware or software. PSP
information should be reviewed before you install a licensed program, a cumulative
PTF package, or hardware. 
Effective use of PSP information is an important element of your fix management
strategy. PSP information is provided by the IBM® software support center for you to use
when installing a licensed program, cumulative PTF packages, or hardware.
You should review this information before you do any software installations
to stay informed about potential conditions that could impede your software
installation process. You can also use the PSP information to order preventive
service planning information and review the recommended High Impact PERvasive
(HIPER) fixes periodically or you can order the HIPER PTF group. The HIPER
PTF group is updated every other week. Be sure to use
the most recent edition of the PSP information as the IBM software support center provides frequent
updates.
To print PSP information that you have ordered and downloaded
to your server, use the instructions in Display and print fix cover letters.
The PSP information is placed in QAPZCOVER when it is sent to you.
