File Cache in Enterprise Server 4.0
250 Netscape Enterprise Server Administrator’s Guide
This directive is intended to be used on Unix platforms that have native OS
support for
PR_TransmitFile
, which currently includes HPUX and AIX. It is
not recommended for other Unix platforms.
TransmitFile=”true”
File Cache Dynamic Control and
Monitoring
An object can be added to
obj.conf
to enable the NSFC file cache to be
dynamically monitored and controlled while the server is running. Typically
this would be done by first adding a
NameTrans
directive to the “default”
object:
NameTrans fn="assign-name" from="/nsfc" name="nsfc"
Then add a new object definition:
<Object name=nsfc>
Service fn=service-nsfc-dump
</Object>
This enables the file cache control and monitoring function to be accessed via
the URI, “
/nsfc
.” By changing the “from” parameter in the
NameTrans
directive, a different URI can be used.
Accessing this URI displays the following information:
• Number of file entries in the cache.
• Amount of heap space being used by the cache.
• Amount of virtual memory space used to map file contents.
• Total number of cache hits.
• Number of hits on cached file information.
• Number of hits on cached file contents.
• Parameter setttings.
• List of the current cache entries.
