CODASYL DBMS

Oracle Corporation's CODASYL DBMS Release 7.0 provides options supporting very large memory addressing and hot standby for performance and availability. Also offers added improvements for reliability to manufacturing and shop floor control environments using this
database.

Very Large Memory Addressing Support
A shared record cache allows the DBMS to use as much physical memory as a computer system can support, so that frequently accessed records can be stored in memory and reduce disk I/O. The advantages include reduced overhead and improved response time.

Hot Standby Option
The Hot Standby Option prevents the DBMS database from becoming a single point of failure by physically duplicating the database at a geographically remote site. In the event of failure, the "hot standby" database becomes the master database and takes over application processing. This does not require specific hardware to operate, and no changes to the application code are needed.
