Reviewing software PTF (fix) requirements

Before you begin the installation process, make sure that your server is ready by reviewing your requirements for program temporary fixes (PTFs).

For this release, for example, a PTF for accepting online software agreements for Licensed Internal Code and the i5/OS™ operating system is required to be temporarily applied before you upgrade. If you are upgrading to V5R4, a PTF to allocate additional space for the Licensed Internal Code before you upgrade might also be required.

• Finding the latest PSP information
  Keep informed on the most recent information about conditions that could impede your software installation process.
• Analyzing fixes you currently have on your system
  A fix cross-reference summary list allows you to analyze the program temporary fixes (PTFs) and Licensed Internal Code fixes you currently have installed on your system.
• Required: Installing Prepare for install PTFs for V5R2 and V5R3
  Situations can arise that require specific program temporary fixes (PTFs) before you can install a new release.
• Installing optional PTF to choose disk configuration
  Today, as part of the automatic installation process, all nonconfigured disk units are added to the system auxiliary storage pool (ASP). If you are using automatic installation to upgrade from V5R2 and do not want nonconfigured disk units added, PTFs are available.
• Permanently applying program temporary fixes (PTFs)
  Temporarily applied PTFs require a considerable amount of disk storage space. Do this only for products and temporarily applied PTFs that you have verified on your system.
• Adding fix support for currently installed licensed programs
  IBM^® licensed programs that are installed on your system are not automatically supported after an upgrade to a new release.
