Question
What is the most common reason for a PTF installation failure?
 
Answer
Some of the C, C++, or HPJ PTFs fail to install because there is not enough memory space to compile or link a module.

Users should use region=0M, and make sure that no MVS system exits are in place to limit memory usage by a batch application.

System programmers should check the following for system settings that restrict the amount of memory that a program can use:

  • IEFUSI user exit
  • IEALIMIT

Note: Sometimes installations default "0M" to a predefined value. In this case, you should check with the system administrator for the largest region size allowed. The closer to 2 GB the better.

The following information provides a list of other areas to consider:

    • If you are using the TSO OMVS command, your region size when coming in through TSO is the REGION size you specify on your logon panel.
    • For batch, your region size is the REGION parameter in the job or step.
    • If you are running through rlogin or telnet, ask your system programmer about increasing MAXASSIZE in the BPXPRMxx parmlib member. Note: MAXASSIZE can be overrriden by the IEFUSI user exit.
