Maximum Directory Cache Buffers =
number
Specify the maximum number of cache buffers that the system
can allocate for directory caching.
Supported values: 20 to 4000
Default: 500
This parameter keeps the system from allocating too many
directory cache buffers so that memory is available for other
server processes.
Increase this limit if the server responds slowly to directory
searches.
Decrease this limit if too much memory is being allocated for
directory caching.
If users are warned that the server is low on memory, this
parameter should be one of the first to be reduced. (Reboot the
server to return the memory to the cache buffer memory pool.)
When a directory cache buffer is allocated, the allocation is
permanent until the server reboots; the buffers don’t return to file
caching when the need for directory cache buffers decreases.
This parameter can be set in the STARTUP.NCF file.
Minimum Directory Cache Buffers =
number
Specify the minimum number of cache buffers that the system
can allocate for directory caching.
Supported values: 10 to 2000
Default: 20
The number needs to be high enough that directory searches can
be done quickly, but no higher than necessary.
If the system doesn’t need the minimum number of directory
cache buffers, the buffers can’t be reallocated to file caching. The
unneeded portion remains unused.
If the server responds slowly to directory searches after it is
booted, monitor the number of directory cache buffers usually
allocated for directory caching.
If the number is significantly higher than this limit, consider
increasing the limit to remove the delay time that normally occurs
while the server is self-configuring. Use MONITOR to view the
current statistics.
This parameter can be set in the STARTUP.NCF file.
