XPAGES (SUBSYS Object)

For the SUBSYS object, XPAGES specifies the maximum number of 1024-word pages

of memory that can be allocated in the extended data segment. The extended data

segment is used to store line, PU, and LU resource control blocks (RCBs). Because no

swap file is defined to back up this memory, in-use pages are locked.

It is important to keep XPAGES to a value consistent with error-free execution of

SNAX. If the value is too low, ADD commands are rejected, error codes are returned to

the OPEN requests made by the HP NonSTop system, and SNA session initiation

requests are rejected. In all of these cases, the error code or sense code indicates a

lack of buffer space or resources.

The XPAGES attribute can be altered before or after the service manager is started.

Default: EXTPOOLPAGES value in the PROFILE object, or 2000
