ALTER DATAVOLS
ZTMF-MAP-Alter-DataVols
is an extensible structured token specifying the data volume attributes to be
altered. This token is required; only one occurrence is allowed. This token
contains the following field:
ZRecoveryMode
specifies whether audit trail files are held on disk until they are no longer
required for volume recovery. The following values are valid:
ZTMF-VAL-RecovMode-Online
directs TMF to retain sufficient audit trail files on disk so that volume
recovery does not need to restore audit information from an archived audit
dump. Retaining audit trail files on disk can affect audit trail management
and transaction processing; transaction processing, for example, is
disabled if it causes the audit trail to exceed a capacity threshold. If this
field is null, the value is ZTMF-VAL-RecovMode-Online.
ZTMF-VAL-RecovMode-Archive
directs TMF to release audit trail files so that they are not retained on disk
solely for the purpose of volume recovery. If volume recovery becomes
necessary, one or more audit dumps might need to be restored. This value
is valid only if audit dumping is configured for the associated audit trail.
