Installing PTFs and analyzing your system for object conversions (V5R4 to IBM i 7.1 upgrade)
When or after you upgrade your system from
V5R4 to IBM® i
7.1,
conversions occur on program objects in libraries, Java™ programs in directories, spooled files,
and integrated file system names in file systems that are not case-sensitive.
To have adequate time to prepare your system for the upcoming
conversions, allow extra time before the upgrade to download planning
PTFs for object conversion, analyze your system, and take necessary
proactive steps for a successful upgrade. Such steps might include
recompiling existing programs or, if programs cannot be converted,
acquiring a new version from your software provider. You also might
need to plan for possible down times.
Note: If this type of preparation
is normally done by a third party, contact your application provider
for assistance.
The planning PTFs for object conversion that you download include information and tools to help you prepare for the upgrade. The release level from which you are upgrading determines the PTFs that you use. These PTFs include the Analyze Object Conversion (ANZOBJCVN) command, which is used to collect information about the following objects:
- Programs, modules, service programs, and SQL packages in all specified user libraries. By running the command, you can determine if they can be converted for IBM i 7.1. You also will have an estimate of the time required for these conversions.
- Java programs from all the specified user directories. An estimate of the time required for conversion is given.
- The total number of spooled files on each auxiliary storage pool (ASP) and the time to perform this conversion either during or after the upgrade.
- Objects with names that contain characters affected by new Unicode characters and casing rules in IBM i 7.1. These objects are in directories that exist in file systems that are not case sensitive; for example, “root” (/) and user-defined file systems with CASE(*MONO).
To begin the steps of preparing your systems
for V5R4 to IBM i
7.1 object
conversions, following these general directions. - Review Information APAR II14482 for the
commands and function included with the conversion PTFs. This information
APAR is in the preventive service planning information about the Support for System i®
Web page. Select the link for technical databases; then select
the link for Authorized Problem Analysis Reports (APARs). - Follow the suggestions and directions in the IBM Redpaper publication IBM i Program
Conversion: Getting Ready for IBM i V6R1
. - Download the planning PTFs that are identified in the Redpaper publication.
