Detailed information for the notes.ini Keyword: 

FTG_Use_Sys_Memory


Short Description: Will instruct the full-text (FT) engine to directly use the operating system memory manager.

Description:
he FTG_USE_SYS_MEMORY setting in NOTES.INI was introduced in Domino 5.0.9 to reduce memory fragmentation. When performing large full-text searches, large blocks in Notes memory can be allocated. The memory is required for a small period of time, but the Notes Memory Manager does not free the allocated memory. This results in memory fragmentation.

Setting FTG_USE_SYS_MEMORY=1 will instruct the full-text (FT) engine to directly use the operating system memory manager for large allocations, instead of requesting memory through the Notes Memory Manager.

Default:

When absent or set to 0, the full-text engine will allocate memory from the Notes Memory Manager.

Recommendation:

Disable this setting for all versions of Domino from 6.0 through 6.5.3.
Enable this setting for Domino 6.5.4 and later.

Restrictions:

Using this setting in Domino 6.0 thru 6.5.3 is likely to cause the server to crash. This issue was addressed in Domino 6.5.4. It is safe to enable this setting for Domino 6.5.4 and later.

Restarts:

A server restart is required for these changes to take effect.
