The MHP normally shuts down automatically at abnormal termination. Automatic shutdown can be suppressed so that the user does not need to enter an operating command to release shutdown status.

To use this facility, specify holdlimit in the -e option of the test start command.

After the test start command has been executed, applications can be started in the same way as when not using the MCF online tester.

Figure 7-1 shows an example of transaction processing from receiving to sending a message. If the MHP terminates abnormally, MCF resources are restored to their status before the transaction began.

Figure 7-1 Example of transaction processing from message receive to message send

Explanation:

1. Messages sent during a test are handled as follows:
   

   Message type	-e option of test start command
   	swmsg specified	swmsg omitted
   Inquiry response messages	Sent	Sent
   Branch messages	Not sent#	Sent

   #: The interface is checked at message send and an error status code is returned if an error occurs.

2. Resources of resource managers other than the MCF are restored to their previous status when backout is specified in the -e option of the test start command. Updated resources are not restored when backout is omitted.
3. The send message is output if one exists.
