Installations may require that their transaction manager log streams retain data for a certain length of time to meet audit requirements. This data must be kept for the retention period, even when it has been marked for deletion via the IXGDELET service. Using automatic deletion and a retention period, you can archive the data for the required length of time without having to move the data out of the log stream, and without having the archived data interfere with the transaction manager. For example, log TRANS1 needs to have data in the log stream for at least 30 days, even if it has been marked for deletion. You can specify RETPD(30) AUTODELETE(NO) to keep the data for the required amount of time. Even if data is marked for deletion via IXGDELET within the 30 day retention period, it is kept in the log stream and can be accessed by a system logger application using the IXGBRWSE service with VIEW=ALL.
