Explanation: FASTREPLICATION is an optional parameter that
indicates whether the use of fast replication for data set recovery
is required, preferred, or not desired.
The following are parameters of the FASTREPLICATION parameter:
- PREFERRED
- Indicates that fast replication should be used when possible.
If fast replication cannot be used, the data set is recovered through
traditional copy methods.
- REQUIRED
- Indicates that if fast replication cannot be used, the recovery
is to fail.
- NONE
- Indicates that only traditional copy methods are to be used.
Defaults: None.
Notes: - Using the FASTREPLICATION parameter overrides the FASTREPLICATION
value specified using the SETSYS FASTREPLICATION command. If not specified,
the value of SETSYS FASTREPLICATION is used.
- FASTREPLICATION is valid only for recovery from disk. If the recovery
is from tape, the parameter is ignored.
- FASTREPLICATION is valid with DSNAME only. It is not valid with
the COPYPOOL or TOVOLUME parameters.
- To recover data sets only when fast replication can be used, specify
FROMDASD with FASTREPLICATION(REQUIRED).
