MAXDUMPTASKS=dtasks, ADSTART=(time1d time2d time3d), DUMPIO=(n,m), VOLUMEDUMP(CC={STANDARD | PREFERRED | REQUIRED | VIRTUALREQUIRED | VIRTUALPREFERRED | CACHEREQUIRED | CACHEPREFERRED}), MAXDUMPRECOVERTASKS=rdtasks

Explanation

A QUERY command was issued with the SETSYS or BACKUP parameter.

The maximum number of full volume dump tasks allowed for concurrent processing is dtasks. The earliest time automatic dump can start is time1d, expressed as hh:mm (hours, minutes). The latest time automatic dump is allowed to start is time2d, expressed as hh:mm (hours, minutes). The time after which no more full volume dumps are started is time3d, expressed as hh:mm (hours, minutes). The DFSMSdss input/output optimization options for full volume dump, n, and for the DFSMSdss datamover function, m, are given for DUMPIO.

These values of n and m are the same as specified for the DFSMSdss OPTIMIZE keyword:
Value
Meaning
1
DFSMSdss reads one track at a time.
2
DFSMSdss reads two tracks at a time.
3
DFSMSdss reads five tracks at a time.
4
DFSMSdss reads one cylinder at a time.

VOLUMEDUMP(CC=) indicates the concurrent copy technique that is specified for dump volumes.

STANDARD indicates that concurrent copy is not used to back up the volume. Normal backup processing is used.

PREFERRED indicates that either virtual or cache based concurrent copy is preferred for processing dump volumes. If a concurrent copy session cannot be established, then normal processing is used.

REQUIRED indicates that either virtual or cache based concurrent copy is required for processing dump volumes. If a concurrent copy session cannot be established, then processing fails.

VIRTUALREQUIRED indicates that virtual concurrent copy is required to process dump volumes. If a virtual concurrent copy session cannot be established, then processing fails.

VIRTUALPREFERRED indicates that virtual concurrent copy is preferred for processing dump volumes. If a virtual concurrent copy session cannot be established, then normal processing is used.

CACHEREQUIRED indicates that cache based concurrent copy is required to process dump volumes. If a cache based concurrent copy session cannot be established, then processing fails.

CACHEPREFERRED indicates that cache based concurrent copy is preferred for processing dump volumes. If a cache based concurrent copy session cannot be established, then normal processing is used.

MAXDUMPRECOVERTASKS indicates that the maximum number of full volume recovery from dump tasks allowed for concurrent processing is rdtasks.
