|
|
<div><p>When a program that uses commitment control is called, monitor
|
|
for unexpected errors and perform a rollback operation if an error occurs. </p>
|
|
<p>For example, uncommitted records can
|
|
exist when a program encounters an unexpected error such as an RPG divide-by-zero
|
|
error.</p>
|
|
<p>Depending on the status of the inquiry message reply (INQMSGRPY) parameter
|
|
for a job, the program sends an inquiry message or performs a default action.
|
|
If the operator response or the default action ends the program, uncommitted
|
|
records still exist waiting for a commit or rollback operation.</p>
|
|
<p>If another program is called and causes a commit operation, the partially
|
|
completed transaction from the previous program is committed.</p>
|
|
<p>To prevent partially completed transactions from being committed, monitor
|
|
for escape messages after the CALL command. For example, if it is an RPG program,
|
|
use the following coding:</p>
|
|
<pre>CALL RPGA
|
|
MONMSG MSGID(RPG9001)
|
|
EXEC(ROLLBACK) /*Rollback if pgm is canceled*/</pre>
|
|
<p>If it is a COBOL program:</p>
|
|
<pre>CALL COBOLA
|
|
MONMSG MSGID(CBE9001)
|
|
EXEC(ROLLBACK) /*Rollback if pgm is canceled*/</pre>
