Ensuring sufficient memory is available to start the IPP Server

The IPP Server requires at least 200 megabytes (MB) of memory. Therefore, you might need to increase the region size before you start the IPP Server. The way that you increase the region size depends on how you start Infoprint Server:

JCL startup procedure: Specify a region size of 200 MB in the REGION parameter on the EXEC statement in the JCL startup procedure. If the REGION parameter is not specified, the default region size that is defined for your installation is used.

Start command

If you enter a Start of change

start

command on the z/OS® UNIX command line, make sure the MAXASSIZE parameter in the BPXPRMxx member of SYS1.PARMLIB is at least 200 MB. The MAXASSIZE parameter determines the system-wide maximum region size for an address space. (You can set the MAXASSIZE parameter dynamically with the SETOMVS command.)

Examples:

This statement sets the maximum region size to 200 MB:

MAXASSIZE(209715200)    /* 200*1024*1024 = 200MB       */

This command sets the maximum region size to 200 MB:
```
SETOMVS MAXASSIZE=209715200
```

Tips:

The ASSIZEMAX parameter of the RACF® ADDUSER and ALTUSER commands, which lets you specify the maximum region size for a particular user, overrides the MAXASSIZE parameter.
Be careful when you are using the SHRLIBRGNSIZE OMVS parameter in a 31-bit environment because it limits the size of usable regions across the system.
The z/OS IEFUSI user exit can modify the region size of an address space. IBM® strongly discourages you from altering the region size of address spaces in the OMVS subsystem category. For more information about the IEFUSI exit, see z/OS MVS Installation Exits.
If you enter a start command on the TSO/E OMVS command line, make sure the SIZE parameter on the TSO/E LOGON panel specifies at least 200 MB. The SIZE parameter determines the maximum region size for an address space.
