OUTBUFF—Output log buffer size
Use the Modify Log Output Buffer Pool Size panels or the OUTBUFF command to specify the buffer size of the output log. This is the amount of storage that the Log Manager uses when writing data to active log data sets.
The Log Manager constructs 4-KB buffers. The value that you specify is the total number of KBs, and the value must be a multiple of four. For delta amounts, batch and MVS console issued commands must be a multiple of four. If the value is not a multiple of four, the value is rounded to the nearest multiple of four.
