Operating System Issues
 Server resources. Server resources can be divided into LAN, disk, and
processor resources. LAN and disk resources are the number of buffers
available. Processor resources are the number of service processes
available. When a network packet arrives or when a disk read or write is
performed, a buffer should be available to hold the data until a service
process is available to service it. Running low on either buffers or service
processes for even a brief period can cause high utilization on the server
and delay for the users.
To understand how server parameters work together to control the
allocation of server resources, see “Monitoring Allocated Services” on
page 86.
For the procedure to configure the allocation of packet receive buffers
(communication buffers), see Increasing Maximum and Minimum Packet
Receive Buffers in the Server Communications Administration Guide and
SET > Communications Parameters in Utilities Reference for parameter
descriptions.
For information on controlling the allocation of directory cache, see
Tuning Directory Cache for the Traditional File System in the Server
Memory Administration Guide and SET > Directory Caching Parameters
for the Traditional File System in Utilities Reference.
For setting up and tunning cache buffers in the NSS file system, see
Setting the Cache Buffers in the Novell Storage Services Administration
Guide.
For parameter descriptions, see also the service processes parameters in
SET > Miscellaneous Parameters in Utilities Reference.
We suggest that the server parameters in the following table be set as
indicated to avoid running low on server resources. This is especially
important if you have 100 or more users. To change the following
parameters, you can use NetWare Remote Manager at the workstation or
SET or MONITOR at the server console.
In NetWare Remote Manager, click the Set Parameters link in the
navigation frame > Category > current value for parameter. Enter the
new value and then click OK.
In MONITOR, from the Available Options menu, select server
Parameters > Category > current_value_for_parameter and then press
Enter. Enter the new value, and then do applicable action.
