Directory Caching Parameters for the Traditional File System
Use to
Specify how few cache buffers can be available before the
operating system warns you that the number of buffers is getting
low.
Supported values: 0 to 1000
Default: 2
For example, if the value of the Minimum File Cache Buffers
parameter is set to 20 and this parameter is set to 25, you are
warned when all but 45 cache buffers are allocated for other
processes.
Regardless of how this parameter value is set, the operating
system will issue a warning when it reaches the minimum number
of cache buffers. You receive the following message: Cache
memory allocator exceeded minimum cache buffer left limit.
Directory caching allows fast access to frequently used directories. A
directory cache buffer is a portion of NetWare
memory) that holds entries from the directory table.
A directory entry stays in a cache buffer as long as it is accessed frequently
(default=33 seconds). The system can overwrite the directory entry if the
allocated directory cache buffers are accessed more frequently.
Directory caching and file caching work together, however. In tuning the
server, directory caching and file caching need to be balanced for maximum
performance.
Remember also that the directory and file caching parameters in SET apply
only to NetWare servers using the Traditional File System. In contrast, the
Novell Storage Services (NSS) file system provides improved resource use,
requiring less memory to mount multiple volumes.
