NSS Buffer Cache Commands
Use these NSS commands at the server console to change your cache buffers:
 nss /MinBufferCacheSize sets the minimum buffer size. The
default is 512. The range is 256 to 1048576. When NSS is loaded, it
requires at least 512 cache buffers.
 nss /MinOSBufferCacheSize sets the minimum size for
NetWare. The default is 1024. The range is 1024 to 1048576. We do not
recommend that you set this value below 1024.
 nss /NameCacheSize sets the number of Name Cache entries. NSS
keeps a cache of file and directory entry names it has recently looked up.
This speeds up opening files and path searches. The default is 2111. The
range is 3 to 65521.
 nss /(No)NameCache sets Name Cache to ON or OFF. The default
is ON.
 nss /(No)CacheBalance sets the buffers to percentages rather than
integers for dynamic balancing of free memory for the buffer cache. The
default is ON. Use this switch with /MinBufferCacheSize.
 nss /CacheBalanceTimer sets the cache balance timer in seconds.
NSS checks the total number of cache buffers in the system and
determines if the CacheBalance percentage is met. NSS then gives or
takes the appropriate number of cache buffers. The default is 30. The
range is 1 to 3600.
 nss /AuthCacheSize sets the number of Authorization Cache
entries. If many trustees have been set on different files and directories,
we recommend that you increase this number. The default is 1024. The
range is 16 to 50000.
 nss /BufferFlushTimer sets the Flush Time for modified cache
buffers in seconds. The default is 1 second. The range is 1 to 3600
seconds.
 nss /CacheStats shows the cache buffer statistics.
Other NSS Commands
Use these NSS commands at the server console to manage NSS:
 nss /Activate=volume_name activates an NSS volume.
 nss /Deactivate=volume_name deactivates an NSS volume.
