The Virtualization Cookbook for SLES 10 SP2 - z/VM - IBM

Chapter 5. Servicing z/VM
You cannot solve a problem with the same kind of thinking that created it.
--Albert Einstein
This chapter describes how to apply the two main types of service:
► A Recommended Service Upgrade (RSU) which is analogous to a Service Pack.
► A Programming Temporary Fix (PTF) which is analogous to a bug fix.
The processes to install these types of service are basically the same.
The application of corrective service to z/VM is covered in two manuals:
► z/VM V6.1 Guide for Automated Installation and Service, (see Part 4), on the Web at:
http://publibz.boulder.ibm.com/epubs/pdf/hcsk2c00.pdf
► z/VM Service Guide, version 6, release 1, on the Web at:
http://publib.boulder.ibm.com/epubs/pdf/hcsf1c00.pdf
These manuals are much more complete than this chapter. You might consider using these
first, rather than this chapter, or you should certainly use them as references.
VMSES/E is a component of z/VM that provides the SERVICE and PUT2PROD EXECs. The
SERVICE EXEC:
► Installs an RSU or applies CORrective service for z/VM components, features, or
products.
► Displays either the RSU level of the component specified or whether a particular PTF or
APAR has been applied (when used with STATUS).
► Creates PTF bitmap files (when used with BITMAP).

Important: When applying service, there is always a chance that you may want to back it
out. It is recommended that you have an up-to-date backup of your system before starting
this section.
