Short Description: To reduce the amount of memory needed to handle file attachment uploads this entry can be used to control the size of the memory buffer used to process multi-part form data.
If large file attachments are uploaded to the Web server, out of memory conditions can result, which prevent the transaction from completing. In the worst case, low memory conditions for the HTTP task can lead to HTTP task crashes for those functions of the IBM® Lotus® Domino® server that do not handle low memory conditions.
To reduce the amount of memory needed to handle file attachment uploads, the NOTES.INI variable DominoMultiPartPostBufferSize can be used to control the size of the memory buffer used to process multi-part form data.
Syntax: DominoMultiPartPostBufferSize=<n> where <n> is the number of megabytes to allocate to the memory buffer.
Additional information: The size of the buffer can be affected by the NOTES.INI variable DSAPI_MAX_POST_DATA_BUFF_SIZE. If DSAPI_MAX_POST_DATA_BUFF_SIZE is greater then DominoMultiPartPostBufferSize then the maximum buffer size will be set to DSAPI_MAX_POST_DATA_BUFF_SIZE. By default, DSAPI_MAX_POST_DATA_BUFF_SIZE is set to 1 megabyte and cannot exceed 100 megabytes. Therefore, DominoMultiPartPostBufferSize has a 10 megabyte minimum and a 100 megabyte maximum
Default: 10 MB
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.
