Tunable Parameters and Memory
Guidelines
The following table shows the tunable parameter guidelines for IPC-1600.
IPC-1600 TUNABLE PARAMETERS

NCLIST | | 120 | | 170 | 560 | 1180 |
NPROC | | 100 | | 150 | 200 | 400 |
NREGION | | 210 | | 300 | 600 | 1200 |

The installation of the IPC-1600 UNIX system driver and related software is independent of these requirements. However, to obtain proper system performance, these parameters should be adjusted before the installation of the IPC-1600. Refer to the UNIX System V/ 386 Operations/System Administration Guide for additional information and procedures on setting tunable parameters. By adjusting these parameters and then installing the IPC-1600 UNIX system software, only one system reboot is necessary to install both the new tunable parameter data and the IPC-1600 data.
Failure to adjust these parameters may result in table overflow warning messages and poor performance.
