The new Delayed Durability feature can greatly enhance performance; however, should a system fail, database recovery could take considerable time if the transaction logs held substantial volumes of data not yet flushed to data and index files.
To this end, a new Restore Point feature has been introduced. A Restore Point is a position in a transaction log to which FairCom Server’s automatic recovery can roll back the system in event of system failure.
The Restore Point is used for restoring a system to a point in time coordinated with the application as a known good state. After restoring the system to a Restore Point, the application can be designed to perform work that was not recovered. For example, those applications maintaining their own journal of operations. By coordinating a known good state in time between the application and the server’s transaction logs, these applications can quickly recover back to a point in time when absolutely needed.
For more information, see the Coordinate Application Recovery with Transaction Restore Points in the c-treeACE V11 Update Guide.
