Detailed information for the notes.ini Keyword: 


Short Description: Specifies the size of the router database cache used to cache mail databases in the router process.


Represents the number of entries allocated for the router database cache. If not used, the default is based on NSFBufferPoolSize (three per MB), i.e. three times bigger than NSFBufferPoolSize, and the maximum is capped to 20000 entries at startup, but reallocation may occur and the number of 20000 entries could exceed it. In brief: it represents a cache of opened mail database handles.

You can view statistics relating to dbcache performance with 'show stat mail.dbcache*'

Mail.DBCacheAged =                  ; the number of entries that had aged and been deleted
Mail.DBCacheEntries =            ; the current number of cache entries
Mail.DBCacheForcedOut =          ; the number of cached entries forced out due to lack of available cache
Mail.DBCacheHighWaterMark =      ; the highest number of entries that had been cached
Mail.DBCacheHits =         ; the number of times a requested db handle was already in cache
Mail.DBCacheMaxEntries =         ; the maximum number of entries (RouterDbCacheSize)
Mail.DBCacheReads =        ; the number of times cache was read


The value can be set with the 'set config' command, but a router restart is required in order for the value to take effect.

Default value:
The default is NSFBufferPoolSize * 3.


UI equivalent:
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.
