Save Save File Data (SAVSAVFDTA)

The Save Save File Data (SAVSAVFDTA) command saves the contents of a save file to tape or optical media. This command saves the save data in the save file to the device in a way that allows you to restore objects directly from the device.

A save file containing data created by the Save Licensed Program (SAVLICPGM) command cannot be saved by this command.

The information written on media by this command is similar to the data that was previously written to the save file by the save command that originally created the save file data. This includes the object descriptions, and object contents that existed when the original save operation was done.

This command uses only the save file and device description objects; it does not refer to or modify the description or contents of the objects included in the file save data. Thus, objects included in the save file are not locked during the running of this command, and the save history information (date, place, and time when each object was last saved) is not updated by this command for each object in the save file.

The description of the save file is not included in the save operation (unless it was included with the objects that were saved to create the save data in the file). In addition, this command does not update the save history information for the save file object, so the last save operation date, time, and place always identify the last save operation of the save file object description, not its contents.

Note: This command ignores all file overrides currently in effect for the job, except for the output file.

Restrictions:

You must have use (*USE) authority for the save file and *USE authority for the tape or optical device description.
If a tape is used, it must have a standard label.
The save file cannot be in use by a job running at the time the save operation occurs.

Save file (SAVF)

Specifies the save file whose contents are to be saved.

Note: The save file must contain data written by a previous save command or an error message is sent, and its contents are not saved to media.

This is a required parameter.

Qualifier 1: Save file

name: Specify the name of the save file whose contents are to be saved.

Qualifier 2: Library

*LIBL: All libraries in the library list for the current thread are searched until the first match is found.

*CURLIB: The current library for the thread is used to locate the save file. If no current library entry exists in the library list, the QGPL library is used.
name: Specify the name of the library where the save file is located.

Device (DEV)

Specifies the name of the device used for the save operation. The device name must already be known on the system by a device description.

This is a required parameter.

optical-device-name: Specify the name of the optical device used for the save operation.

tape-media-library-device-name: Specify the name of the tape media library device used for the save operation.

tape-device-name: Specify the names of one or more tape devices used for the save operation. If a virtual tape device is used, it must be the only device specified. If multiple tape devices are used, they must have compatible media formats and their names must be specified in the order in which they are used. Using more than one tape device permits one tape volume to be rewound and unloaded while another tape device processes the next tape volume.

Volume identifier (VOL)

Specifies the volume identifiers of the volumes, or the cartridge identifiers of tapes in a tape media library device, on which the data is saved. The volumes must be placed in the device in the same order as specified for this parameter.

Single values

*MOUNTED: The data is saved on the volumes placed in the device. For a media library device, the volume to be used is the next cartridge in the category mounted by the Set Tape Category (SETTAPCGY) command.
Note: This value cannot be specified when using an optical media library device.

Other values (up to 75 repetitions)

character-value: Specify the identifiers of one or more volumes in the order in which they are placed in a device and used to save the data.

End of media option (ENDOPT)

Specifies the operation that is automatically done on the tape or optical volume after the save operation ends. If more than one volume is used, this parameter applies only to the last volume used; all other volumes are unloaded when the end of the volume is reached.

Note: This parameter is valid only if a tape or optical device name is specified for the DEV parameter. For optical devices, *UNLOAD is the only special value supported, *REWIND and *LEAVE will be ignored.

*REWIND: The tape is automatically rewound, but not unloaded, after the operation has ended.

*LEAVE: The tape does not rewind or unload after the operation ends. It remains at the current position on the tape drive.

*UNLOAD: The tape is automatically rewound and unloaded after the operation ends. Some optical devices will eject the volume after the operation ends.

Optical file (OPTFILE)

Specifies the path name of the optical file that is used for the save operation, beginning with the root directory of the volume.

For more information on specifying path names, refer to "Object naming rules" in the CL concepts and reference topic in the iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter.

*: The system generates an optical file name in the root directory of the optical volume.
'optical-directory-path-name/*': The system generates an optical file name in the specified directory of the optical volume.

Use optimum block (USEOPTBLK)

Specifies whether or not the optimum block size is used for the save operation.

Note: Specifying USEOPTBLK(*YES) may result in a tape that can be duplicated only to a device that supports the same block size.

*YES

The optimum block size supported by the device is used for Save commands. If the block size that is used is larger than a block size that is supported by all device types, then:

Performance may improve.
The tape file that is created is only compatible with a device that supports the block size used. Commands such as Duplicate Tape (DUPTAP) do not duplicate files unless the files are being duplicated to a device which supports the same block size that was used.
The value for the DTACPR parameter is ignored.

*NO

The optimum block size supported by the device is not used. Save commands use the default block size supported by all device types. The tape volume can be duplicated to any media format using the Duplicate Tape (DUPTAP) command.

Clear (CLEAR)

Specifies whether active data on the media is automatically cleared or replaced. Active data is any file on the media that has not expired. For saves to tape, clearing active data will make any files on the tape volume beyond the last file written by the save operation no longer accessible. For saves to optical, the files written by the save operation can be automatically replaced while other files on the volume remain active, or all active files can be automatically cleared. Clearing does not erase the data, it just makes the files no longer accessible.

Notes:

Clearing a tape does not initialize it. You should initialize tapes to a standard label format before the save command is issued by using the Initialize Tape (INZTAP) command and specifying a value for the NEWVOL parameter.
Clearing an optical volume does initialize it.
If a volume that is not initialized is encountered during the save operation, an inquiry message is sent and an operator can initialize the volume.

*NONE: None of the media is automatically cleared. If the save operation encounters active data on a tape volume or in a save file, an inquiry message is sent, allowing the operator to either end the save operation or clear the media. If the save operation encounters the specified optical file, an inquiry message is sent, allowing the operator to either end the save operation or replace the file.

*ALL: All of the media is automatically cleared.

If tapes are used and a sequence number is specified for the SEQNBR parameter, the first tape is cleared beginning at that sequence number. All tapes following that first tape are completely cleared. To clear the entire first tape, SEQNBR(1) must be specified.

*AFTER: All media after the first volume is automatically cleared. If the save operation encounters active data on the first tape volume, an inquiry message is sent, allowing the operator to either end the save operation or clear the media. If the save operation encounters the specified optical file on the first volume, an inquiry message is sent, allowing the operator to either end the save operation or replace the file.

*REPLACE: Active data on the media is automatically replaced. Optical volumes are not initialized. Other media is automatically cleared in the same way as the *ALL value.

File expiration date (EXPDATE)

Specifies the expiration date of the file created by the save operation. If a date is specified, the file is protected and cannot be overwritten until the specified expiration date.

Notes:

This parameter is valid for tape and optical files.
Specifying this parameter does not protect against a later save operation specifying CLEAR(*ALL).

*PERM: The file is protected permanently.
date: Specify the date when protection for the file ends.

Output (OUTPUT)

Specifies whether a list with information about the saved objects is created. The information can be printed with the job's spooled output or directed to a database file.

*NONE: No output listing is created.

*PRINT: The output is printed with the job's spooled output.

*OUTFILE: The output is directed to the database file specified for the File to receive output (OUTFILE) parameter.

: Note: You must specify a database file name for the File to receive output (OUTFILE) parameter when OUTPUT(*OUTFILE) is specified.

File to receive output (OUTFILE)

Specifies the database file to which the information is directed when *OUTFILE is specified for the Output (OUTPUT) parameter. If the file does not exist, this command creates a database file in the specified library. If a new file is created, the system uses QASAVOBJ in QSYS with the format name QSRSAV as a model.

Qualifier 1: File to receive output

name: Specify the name of the database file to which output from the command is directed. If this file does not exist, it is created in the specified library.

Qualifier 2: Library

*LIBL: All libraries in the library list for the current thread are searched until the first match is found.

*CURLIB: The current library for the thread is used to locate the file. If no library is specified as the current library for the job, the QGPL library is used.

name: Specify the name of the library to be searched.

Output member options (OUTMBR)

Specifies the name of the database file member to which the output is directed when *OUTFILE is specified for the Output (OUTPUT) parameter.

Element 1: Member to receive output

*FIRST: The first member in the file receives the output. If OUTMBR(*FIRST) is specified and the member does not exist, the system creates a member with the name of the file specified for the File to receive output (OUTFILE) parameter.
name: Specify the name of the file member that receives the output. If OUTMBR(member-name) is specified and the member does not exist, the system creates it.
If the member exists, you can add records to the end of the existing member or clear the existing member and add the records.

Element 2: Replace or add records

*REPLACE: The existing records in the specified database file member are replaced by the new records.
*ADD: The new records are added to the existing information in the specified database file member.

Examples

SAVSAVFDTA   SAVF(ONLINE)  DEV(TAP01)  SEQNBR(1)  CLEAR(*ALL)

This command saves the contents of save file ONLINE to the first file on the tape volume on device TAP01. Files that have not ended on either the first tape volume or on subsequent volumes are overwritten without an inquiry message because CLEAR(*ALL) is specified.
