Committing a Transaction

If a transaction completes successfully, the changes that it made to a protected

database are made permanent; this is referred to as “committing the transaction.”

You terminate a TMF transaction and commit the effects of that transaction by invoking

the ENDTRANSACTION procedure. The following table summarizes the statements

that you use to do so, in each of the supported programming languages:

Aborting a Transaction

After a TMF transaction has been initiated but before it is committed, any application

program module that is doing work on behalf of that transaction can terminate the

transaction; this is referred to as “aborting the transaction.”

When a transaction is aborted, all of the changes that were made to the database on

behalf of the transaction are backed out.

You abort a transaction by invoking the ABORTTRANSACTION procedure. The

following table summarizes the statements that you use to do so, in each of the

supported programming languages:
