RESTDSN - Required parameters
Parameter | Description |
|---|---|
dsname | A specific data set name, which may be enclosed in apostrophes The user must have READ authorization for the specified data set. |
RESTDSN - Optional Parameters
Option[Short option] | Description | Format | Examples |
|---|---|---|---|
VOLUME[VOL] | The volume on which the data set resides | Full name or using a pattern | SYSRES PROD* SYS%RS |
DATE | Requests a backup copy that was created on a specific date only DATE and DATERANGE are mutually exclusive. | yyyy/mm/dd | 2019/08/15 |
DATERANGE[DATER] | Requests a backup copy that was created within a specific date range DATERANGE and DATE are mutually exclusive. | yyyy/mm/dd-yyyy/mm/dd | 2019/01/01-2019/08/15 |
ENTRY[ENT] | A positive sequential number from 0, 1, 2, and so on, representing the available entries of a backup copy, according to the specified criteria | <integer> | 0—The latest copy (default) 1—The copy prior to the latest, and so on. |
UNIQueid[UNIQ] | An 8-byte ID that when combined with the data set name identifies each backup copy Use UNIQueid to refer to a specific copy of a data set without having to specify any additional filters. UNIQueid and ENTRY are mutually exclusive. | 8 characters | UNIQueid can be taken from a previous LISTDSN command’s output, to be used in RESTDSN. |
NEWVOL[NEWV] | The command will attempt to restore the data set to the specified volume For SMS-managed data sets, the decision whether to honor the request is done by ACS routines. For non-SMS managed data sets, the decision whether to honor the request is made by the operating system according to the availability of the volume. | volume | PROD01 |
NEWNAME[NEWN] | Restore the data set with a new name. The user must have ALTER authorization for the new data set name. The new name may be enclosed in apostrophes. | dsName | M9.P.JOBS |
NEWMCLASS[NEWMC] | Restore the data set with the specified management class as input to the ACS routines instead of the management class the data set originally had when it was archived. NEWMCLASS and NULLMC are mutually exclusive. | management-class | M9APPLMC |
NULLMC | Restore the data set with null management class as input to the ACS routines instead of the management class the data set originally had when it was archived. NEWMCLASS and NULLMC are mutually exclusive. | - | - |
NEWSCLASS[NEWSC] | Restore the data set with the specified storage class as input to the ACS routines instead of the storage class the data set originally had when it was backed up. NEWSCLASS and NULLSC are mutually exclusive. | <storage-class> | M9APPLSC |
NULLSC | Restore the data set with null storage class as input to the ACS routines instead of the storage class the data set originally had when it was backed up. NEWSCLASS and NULLSC are mutually exclusive. | - | - |
BYPASSACS | Restore the data set with bypassing the ACS routines option. The user must have READ access to the BMC AMI Cloud Resource M9.CLI.RESTDSN.BYPASSACS | - | - |
NODUMP | Requesting that RESTDSN select backup copies only, without considering data set copies found in a volume full dump. The default is to allow selection of backups from a volume full dump. | - | - |
NOCAT | Allow restore without cataloging If the parameter is not specified, the default is to catalog the data set upon restore. | - | |
REPLACE | Restore the backup copy onto the target data set and replace it. If the parameter is not specified, the default is not to replace the current data set | - | - |
RESTDSN - Output
The output displays the given RESTDSN command and parameters, followed by the requested information:
DATA SET <dsname> WAS RESTORED FROM A FULL VOLUME DUMP MADE ON <yyyy/mm/dd> at <hh:mm:ss>
If the request fails, the complete log will be displayed. If the requesting user is not available, the first 100 records of the output will be printed in the executing agent's log.
RESTDSN - Examples
The following examples demonstrate various ways to use the command.
Restoring the latest copy of a data set with a new name
Restoring the latest copy of a data set with replace
Restoring the latest copy of a data set, requesting to use only incremental backup as the input
Restoring the latest copy of a data set with the same name, on a new volume, without cataloging
Restoring the latest copy of a data set with specific management class and storage class as input to the ACS routines
Restoring a non-cataloged data set within a date range using ENTRY or UNIQUEID
When restoring a data set other than the latest, LISTDSN the volume first for the available copies:
The restore can be executed using the same search criteria specified on the LIST command, where the specific copy is selected using ENTRY:
There is no need to specify any additional search criteria when using the UNIQUEID parameter:
