Understanding OS/390 Jargon

OS/390 jargon can sometimes be extremely intimidating. Here are some common definitions that will help you to get up to speed with the OS/390 operating system:

• APAR (authorized program analysis reports)

  If one needs to correct a serious problem that occurs on a system before a PTF is ready, IBM Support can supply you with an APAR on request.

• MPM

  Multi Processing Monitor (MPM) is the Oracle address space running to support an Oracle instance.

• PDS (Partition Data Set)

  A library to store members (files) in.

• PTF (program temporary fix)

  When IBM Support correct a problem they will supply their customers a tested PTF. Although you may not have the problem, it is wise to install the PTF on your system for preventive reasons.
