HP-UX Directory Server 8.1 configuration, command, and file reference
3.4.1.2 nsslapd-cache-autosize
This performance tuning-related attribute, which is turned off by default, specifies the percentage
of free memory to use for all the combined caches. For example, if the value is set to 80, then 80
percent of the remaining free memory would be claimed for the cache. To run other servers on
the machine, then set the value lower. Setting the value to 0 turns off the cache autosizing and
uses the normal nsslapd-cachememsize and nsslapd-dbcachesize attributes.
NOTE:
If the nsslapd-cache-autosize attribute and nsslapd-cache-autosize-split attribute
are both set to high values, such as 100, then the Directory Server may fail to start and return
an error message. To fix this issue, reset the nsslapd-cache-autosize and
nsslapd-cache-autosize-split attributes to a more reasonable level. For example:
nsslapd-cache-autosize: 60
nsslapd-cache-autosize-split: 60
DescriptionParameter

3.4.1.3 nsslapd-cache-autosize-split
This performance tuning-related attribute specifies the percentage of cache space to allocate to
the database cache. For example, setting this to 60 would give the database cache 60 percent of
the cache space and split the remaining 40 percent between the backend entry caches. That is, if
there were two databases, each of them would receive 20 percent. This attribute only applies
when the nsslapd-cache-autosize attribute has a value of 0.
NOTE:
If the nsslapd-cache-autosize attribute and nsslapd-cache-autosize-split attribute
are both set to high values, such as 100, then the Directory Server may fail to start and return
error message. To fix this issue, reset the nsslapd-cache-autosize and
nsslapd-cache-autosize-split attributes to a more reasonable level. For example:
nsslapd-cache-autosize: 60
nsslapd-cache-autosize-split: 60
DescriptionParameter
