Maximum buffer size

The maxbuffersize parameter specifies the size of the transmission buffers in which application data or terminal data flows to CICS servers.

maxbuffersize=<number>
Description
Set the value in the range 4 - 32 to specify the number of kilobytes for the maximum buffer size. The value should be large enough to accept the largest possible COMMAREA or terminal input/output area (TIOA) to be used. The maximum COMMAREA size that can be transmitted might be less than the maximum buffer size because of protocol header overheads.

Leave this setting at the default unless the CICS Transaction Gateway is running on a machine that is short of memory.

This parameter is in the CLIENT section of the configuration file.

Default value
If this parameter is not specified, the default value is 32.
Configuration Tool
In the Configuration Tool, you can set the value of maxbuffersize in the Maximum buffer size field on the Resourses tab in the Client daemon configuration page.
