Short Description: This setting controls how long an entry is allowed to remain in the database cache.
Database entries are removed from cache when the cache entry count exceeds the value reported by the Domino statistic named Database.DbCache.MaxEntries or when they have been inactively in the cache for more than NSF_DBCACHE_CLEAN_HOLD_TIME.
NSF_DBCACHE_CLEAN_HOLD_TIME can be set to some value less than 10,000. This might be desired to reduce cache memory demands. A value of 0 causes the default (10,000) value to be in effect. A value of -1 causes the cache behavior to revert to pre-Domino 7 behavior.
Very small value for NSF_DBCACHE_CLEAN_HOLD_TIME may cause undesirable performance issues.
There is no single value that is right for every server. Rather, correct values for this setting are dependent on the host server and the desired goal. Servers with abundant memory will likely experience performance improvements with higher values for this setting. Conversly, lower values will conserve memory at the cost of performance. Values that are too low will likely cause performance problems.
The default is 10,000 minutes (6.6 days).
There is no kown UI setting for this notes.ini variable. But you can specify this setting in the notes.ini settings tab of the configuration settings document.
