Description: Cerner 724Access Downtime Viewer provides continuous access to all clinical data currently available in the Cerner Millennium production database when the Cerner Millennium system or supporting infrastructure is otherwise unavailable. This technology also allows continuous access to a more limited subset of clinical data for cases when the network is unavailable.

The data flows through the 724 architecture via a system of Oracle GoldenGate processes, which replicate Structured Query Language (SQL) statements via trail files from source servers to targets. In the 724 architecture, data is replicated from the production database server to Linux midtier servers, which utilize an Oracle Database. From there, data is replicated to pumper servers at each VA Medical Center (VAMC) and from the pumper to individual devices out in the clinical areas that will be used during downtimes. Data is written to a MySQL database on the device. Data flows from the pumper to the Personal Computer (PC) and is stored in trail files which are stored in C:\724Access\GGS\dirdat directory before being processed through by an Oracle GoldenGate process, which actually writes the SQL statements contained in those trail files to the MySQL database. The MySQL database resides in the C:\724Access\724AccessDB folder. Additionally, when utilizing MySQL enterprise encryption, the database can be encrypted using MySQL Transparent Data Encryption (TDE).
