# How UNIX Kernel Parameters Affect FoxPro for UNIX

ID: Q124715

2.60 UNIX

The information in this article applies to:

- Microsoft FoxPro for UNIX, version 2.6

## SUMMARY

FoxPro for UNIX is affected by UNIX kernel parameters set by the system administrator.

NOTE: The settings provided in this article apply only to SCO UNIX version 3.2.4. Not all of these settings are available in later versions of SCO UNIX.

## MORE INFORMATION

UNIX allows the system administrator to tune or set kernel parameters by using the system administrator shell (sysadmsh) or by running a program called Configure.

To configure the kernel through sysadmsh, choose:

      System/Configure/Kernel/Parameters

To run the configuration program outside of the sysadmsh, do this:

      cd /etc/conf/cf.d
      configure

Please consult Chapter 19 of the most recent SCO Operating System's System Administrator's Guide (SAG) for a complete listing of the kernel parameters and their descriptions.

FoxPro for UNIX performance can be impacted by the following system configuration options in the kernel:

### Files, Inodes and Filesystems

        NFILE    - should have no more than 500 set, especially with NFS.
        NOFILES  - per process number of files - 'Too many files open' may
                   be the error message when NOFILES limit has been
                   exhausted.
        FLCKREC  - maximum number of record locks by system.

### Processes, Memory Management and Swapping

        MAXPMEM  - if set to 0 and MEMLIMIT used in the config.fpu,
                   most of the available system memory will be
                   used by FoxPro for UNIX.
        ULIMIT   - may receive 'Out of disk space' if exceed ULIMIT.
        MAXUMEM  - number of 512 K pages.
        MAXSLICE - maximum timeslice for processes.

NOTE: These parameters will affect the behavior for each user of the system.
