page is 1024 words. The extended data segment stores LINE, PU, and LU resource
control blocks (RCBs). Pages are locked while in use.
If the EXTPOOLPAGES value is too low, SCF ADD commands are rejected, error
codes are returned to HP application OPEN requests, and SNA session initiation
requests are rejected. In all these cases, the error code or sense code indicates lack of
buffer space or resources.
Two stand-alone programs, SMSIZE and TSSIZE, can help you determine the
extended memory requirements for your system configuration. Contact your HP
support representative for details.
To change the EXTPOOLPAGES value, issue an SCF ALTER DEVICE command to
the WAN subsystem; for example:
STOP DEVICE $ZZWAN.#SSCP
ALTER DEVICE $ZZWAN.#SSCP, EXTPOOLPAGES 1000
To temporarily override the WAN subsystem value in the SNAX subsystem, issue an
SCF ALTER SUBSYS command to change the XPAGES attribute value; for example:
STOP SUBSYS $SSCP
ALTER SUBSYS $SSCP, XPAGES 1000
NUMSEGIDS n
NUMSEGIDS specifies the number of extended segments to allocate for ESS tables
and BIND tables used by LUNS. Each table resides in a separate segment. For
example, a value 10 allows 10 ESS tables and 10 BIND tables to be resident in
memory.
To change the NUMSEGIDS value, issue an SCF ALTER DEVICE command to the
WAN subsystem; for example:
STOP DEVICE $ZZWAN.#SSCP
ALTER DEVICE $ZZWAN.#SSCP, NUMSEGIDS 20
SETTABNAME filename
SETTABNAME specifies the source file name of the SET table used by LUNS.
If LUNS is not used, filename must be eight blank characters (the default), meaning
no SET table.
If LUNS is used, filename be seven or less characters. SNAX appends the letter O
to the end of this file name and searches for the file on $SYSTEM.SYSnn, where
SYSnn is the subvolume on $SYSTEM from which the system image was loaded. For
Default: n = 10
Range: 1 through 100
Default: Blanks (no SET table)
