System-managed access-path protection

 

System-managed access-path protection (SMAPP) provides automatic protection for access paths.

Using the SMAPP support, you do not have to use the journaling commands, such as the Start Journal Access Path (STRJRNAP) command, to get the benefits of access path journaling. SMAPP support recovers access paths after an abnormal system end rather than rebuilding them while restarting the system or varying on an independent ASP.

The SMAPP support is turned on with the shipped system.

The system determines which access paths to protect based on target access path recovery times provided by the user or by using a system-provided default time. The target access path recovery times can be specified as a system-wide value or on an ASP basis. Access paths that are being journaled to a user-defined journal are not eligible for SMAPP protection because they are already protected.
