DBDELETE
Database" in chapter 4 for what to consider when enabling or disabling this option.
If the process is logging, a call to DBDELETE causes a log record to be written with such
information as the time, date, user identification number, and a copy of the record to be
deleted. In a dynamic transaction, DBDELETE causes a log record to be written after the
physical transaction has been successfully completed. If DBDELETE cannot complete within
a dynamic transaction, an error is returned. This error condition must be checked, and you
must decide to use DBXUNDO, DBXEND, or continue with the remainder of the dynamic
transaction. DBXUNDO will abort the entire transaction. DBXEND will terminate the dynamic
transaction; the modifications completed thus far within the transaction will remain in the
database.
