Description
The SERVNSA parameter, along with the SERVNSSZ parameter, controls non-swappable server areas which are placed above the 2G bar.
Each server table to be allocate above the bar is controlled by a bit in SERVNSA; if the bit is on, the corresponding server table is allocated above the bar. The bits are:
| Bit | Server table placed above the bar |
|---|---|
X'02000000' | FTBL |
X'00004000' | NTBL |
SERVNSSZ (server non-swappable size) is the amount of space in bytes required for the above-the-bar server tables per user. The total amount of storage allocated for non-swappable server areas equals SERVNSSZ rounded to 4 K and multiplied by NUSERS.
When sizing SERVNSSZ, it should accomodate the largest non-swappable table sizes that might be needed.
For more information about server tables above the bar, see the Rocket Model 204 System Manager's Guide.
