CA MII Data Sharing

CA MII Data Sharing (CA MII) protects z/OS data integrity automatically, speeds resolution of resource conflicts in shared DASD environments, and adds additional integrity at a local system level.

CA MII consists of the following facilities:

Global Data Integrity Facility (GDIF)

Prevents simultaneous updates that occur when requests for resources are not communicated to all systems.

Enqueue Conflict Management Facility (ECMF)

Helps Time-Sharing Option (TSO) users and system operators identify and resolve conflicting requests for resources

Enhanced Data Set Integrity Facility (EDIF)

Prevents the most common sources of data set damage, such as damage to attributes or due to DISP=SHR updates
