DCMT VARY DATA SHARING Usage

Specifying a Default Cache

Changes to the default shared cache remain in effect until the system terminates or until another DCMT VARY DATA SHARING command is issued. When a system is restarted after dynamically changing the default shared cache, the default shared cache in effect is that specified in the DMCL used by the system.

The default shared cache affects only files that have not been explicitly assigned a shared cache and for which at least one associated area is shared. The default shared cache has no affect on files that are not associated with a shared area.

Specifying on Connectivity Loss Behavior

If NOABEND was specified, processing continues normally as long as no data sharing requests are done. This is advisable if it is important to keep areas that are not data shared online.

Note: Normal shutdown is not possible because of the connectivity loss orstructure failure.
