Across the world, BASE24 from ACI is one of the major EFT switches used by major financial institutions/Banks. On a daily basis operators working on BASE24 affect many changes in the database.

It is extremely important for BASE24 system administrator to monitor and track these changes carried out by the operators. Regulatory authorities also mandate the monitoring of these changes and availability of these records for the future use for audit purposes.

The Online Maintenance File (OMF) contains records of daily additions, deletions, and updates made to the BASE24 application files. The OMF provides an audit trail of file maintenance operations.
