1.2.5 Transaction Management
DLI library performs the transaction management work, i.e
.committing the changes that have been made and sending out the
messages already built or rolling back all the changes and drop out
all the messages, according to the direction passed from COBOL
application. If the COBOL application does not issue a clear
direction to commit the transaction, ARTIMPP commits
the transaction.
The following table 10 lists the transaction management processes and commands.
