The following buffering modes are available for the persistence of buffered messages to the file system:
NONE specifies that buffered events are not persisted to the file system. Messages are persisted only in memory and will be lost if the integration shuts down or terminates unexpectedly.
HIGH always saves the message to a file on the integration host computer before it is sent, regardless of whether the message is subsequently buffered. The BMC II for z/OS removes the message from the file after it is sent successfully.
LOW saves the message to a file on the integration host computer if the message is buffered to memory. The BMC II for z/OS removes the message from the file after it is sent successfully.
