DASDONLY

The DASDOLNLY communication method has the control file located on a shared DASD volume or a coupling facility list structure.

Benefits

• Requires no CTC devices
• Allows the MIMplex systems to be any combination of sysplexed and non-sysplexed images.
• Solid State DASD provides high performance equivalent to CTC communication options.
• Provides very high performance, if using a coupling facility

Requirements

• A 3380/3390-type DASD volume accessible by all systems participating in the MIMplex.
• A coupling facility list structure (optional).
• If using coupling facility structure control files are used, all MIMplex systems must be in the same parallel sysplex.
