Required Parameter Group

Qualified user space name

INPUT; CHAR(20)

The user space that is to hold all the information for the save operation. The first 10 characters contain the user space name. The second 10 characters contain the name of the library where the user space is located. See User Space Format for the format of the information in the user space.

You can use the following special values for the library name. However, it should be noted that the library name that is actually used is not passed back to the user. Care should be taken when you use these special values to avoid unexpected results.

*CURLIB	The job's current library is used to locate the user space. If no library is specified as the current library for the job, the QGPL library is used.
*LIBL	The library list is used to locate the user space.

Error code

I/O; CHAR(*)

The structure in which to return error information. For the format of the structure, see Error Code Parameter.

User Space Format

The following defines the format for the information in the user space. For detailed descriptions of the fields in the user space format, see Field Descriptions.

Offset		Type	Field
Dec	Hex	Type	Field
0	0	BINARY(4)	Number of variable length records
4	4	BINARY(4)	Offset to first record
8	8	CHAR(8)	Reserved
Note: These fields repeat for each variable length record.
		BINARY(4)	Key
		BINARY(4)	Offset to next record
		CHAR(8)	Reserved
		CHAR(*)	Data

If the length of the data is longer than the key identifier's data length, the data will be truncated at the right. No message will be issued.

If the specified data length is shorter than the key field's defined data length, an error message is returned for binary fields. If the field is a character field, the data is padded with blanks and an error message will not be returned.

Note: This does not apply to keys that allow a list of values to be specified. In these cases, the amount of data read is based on the specified number of entries in the list.

If keys are duplicated in the user space, only the last value for a given key is used for the save operation.

Each variable length record must be 4-byte aligned. If not, unpredictable results may occur.

Field Descriptions

Data. The data used to specify the value for the given key.

Key. The parameter of the Save Object (SAV) command to specify. See Valid Keys for the list of valid keys.

Offset to first record. The offset from the beginning of the user space to the first variable length record.

Offset to next record. The offset from the beginning of the user space to the next variable length record.

Number of variable length records. The number of variable length records that are passed in the user space. The valid range is from 2 through 25.

Reserved. Reserved. The possible value is:

x'00'

This field should contain x'00's.

Valid Keys

The following table lists the valid keys for the key field area of the variable length record. For detailed descriptions of the keys, see the Field Descriptions.

Some messages for this API refer to parameters and values of the Save Object (SAV) command. This table can also be used to locate the key names that correspond to the SAV command parameters. The field descriptions contain, in addition to detailed descriptions, the corresponding parameter values.

Clear. Whether active data on the media is cleared or replaced automatically. Active data is any file on the media that has not expired. Clearing active data removes all files from the volume, starting at the specified sequence number for the tape. Replacing active data on optical media replaces only the optical files created by this operation. The default is 0.

Notes:

Clearing a tape does not initialize it. Before the save command is issued, you should initialize the tape to a standard label format by using the Initialize Tape (INZTAP) command and specifying a value on 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.

The possible values are:

0	None of the media is cleared automatically. If the save operation encounters active data on a tape or 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. (*NONE)
1	All of the media is cleared automatically. (*ALL) If tapes are used and a sequence number is specified for the sequence number key, the first tape is cleared beginning at that sequence number. All tapes following the first tape are completely cleared. To clear the entire first tape, 1 must be specified for the sequence number key.
2	All media after the first volume is cleared automatically. If the save operation encounters active data on the first tape, 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. (AFTER) Note:* This value is not valid for save files.
3	Active data on the media is replaced automatically. Optical volumes are not initialized. Tapes and save files are cleared automatically in the same way as the value 1. (*REPLACE)

Data compaction. Whether device data compaction is performed. The default is 1. The possible values are:

Device data compaction is not performed. (*NO)

Device data compaction is performed if the data is saved to tape and all tape devices specified for the device key support the compaction feature. (*DEV)

Note: If 1 is specified for the data compaction key and 2 is specified for the data compression key, only device data compaction is performed if compaction is supported on the device. Otherwise, data compression is performed if supported on the device.

If 1 is specified for the data compaction key and 1 is specified for the data compression key, both device data compaction and device data compression are performed if supported on the device.

Data compression. Whether data compression is performed. If the save operation is being done while other jobs on the system are active and software data compression is used, the overall system performance may be affected. The default is 2. The possible values are:

0	No data compression is performed. (*NO)
1	If the save operation is to tape and the target device has the hardware compression feature, hardware compression is done. If the feature is not present, or if the save data is written to optical or save file, software data compression is done. Low (SNA) software compression is used for all devices except optical DVD, which uses medium (TERSE) software compression. (YES) Note:* If 1 is specified for the data compression key and 1 is specified for the data compaction key, both device data compaction and device data compression are performed if supported on the device.
2	If the tape device has the hardware compression feature installed, processing proceeds as if 1 were specified for the data compression key. If the compression feature is not installed or if save data is written to optical or save file, processing proceeds as if 0 were specified for the data compression key. (DEV) Note:* If 2 is specified for the data compression key and 1 is specified for the data compaction key, only device data compaction is performed if compaction is supported on the device. Otherwise, data compression is performed if supported on the device.
3	If the save operation is to a save file or optical, low (SNA) software data compression is done. If the save operation is being done while other jobs on the system are active and software data compression is used, the overall system performance may be affected. Low compression is usually faster than medium or high compression. The compressed data is usually larger than if medium or high compression is used. (*LOW)
4	If the save operation is to a save file or optical, medium (TERSE) software data compression is done. If the save operation is being done while other jobs on the system are active and software data compression is used, the overall system performance may be affected. Medium compression is usually slower than low compression but faster than high compression. The compressed data is usually smaller than if low compression is used and larger than if high compression is used. (*MEDIUM)
5	If the save operation is to a save file or optical, high (LZ1) software data compression is done. If the save operation is being done while other jobs on the system are active and software data compression is used, the overall system performance may be affected. High compression is usually slower than low and medium compression.The compressed data is usually smaller than if low or medium compression is used. (*HIGH)

3	The PC save history is updated. The PC archive attribute is set to No. (*SYS)

Use optimum block size. Whether the optimum block size is used for the save operation. The default is 1. The possible values are:

The optimum block size supported by the device is not used. Save uses the default block size supported by all device types. The tape volume can be duplicated to any media format by using the Duplicate Tape (DUPTAP) command. (*NO)

The optimum block size supported by all devices is used. If the optimum block size is used, the following can occur:

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 that supports the same block size that was used.
The value for the data compression key is ignored.

Volume identifier. The volume identifiers of the volumes, or the cartridge identifier of a tape in a tape media library device, on which data is saved. The volumes must be placed in the device in the order specified on this key. After all specified volumes are filled, the save operation continues on whatever volumes are mounted on the device.

Offset		Type	Field
Dec	Hex	Type	Field
		BINARY(4)	Number in array
		BINARY(4)	Length of each volume identifier
		BINARY(4)	Offset to first volume identifier
Note: These fields repeat for each volume identifier.
		BINARY(4)	Offset to next volume identifier
		CHAR(*)	Volume identifier

Length of each volume identifier. The character length of each of the volume identifiers. The possible value follows:

n	The size of a single volume identifier. The maximum size of a tape volume identifier is 6 characters. The maximum size of an optical volume identifier is 32 characters. If a volume identifier larger than the maximum size is entered for this key, it is truncated to the maximum size.

Number in array. The number of volume identifiers that are used during the save operation. The default is 0. The possible values are:

0	The volume currently placed in the device is used. If 0 is specified for a tape media library device, volume identifiers must be supplied by using the Tape Management exit program during the save or restore operation. If 0 is specified, the length of each volume identifier value is ignored. (MOUNTED) Note:* This value cannot be specified for an optical media library device.
1-75	The number of volume identifiers used during the save operation.

Offset to first volume identifier. The offset from the beginning of the user space to the first volume identifier in the list. The possible value is:

n	The offset from the beginning of the user space to the first volume identifier in the list.

Offset to next volume identifier. The offset from the beginning of the user space to the next object volume identifier in the list. The possible value is:

n	The offset from the beginning of the user space to the next volume identifier in the list. If the current volume identifier is the last volume identifier in the array, this value should be 0.

Volume identifier. The volume identifiers of one or more volumes to be used. The possible value is:

Volume identifier

The volume identifiers of one or more volumes to be used.

Dependencies between Keys

The following two tables list the dependencies between the different keys. If the dependency pertains only to a certain value, then that value is also shown (key = n, where n is the value). Otherwise, if the dependency is true for all values of the key, then only the name of the key is given.

The following table lists the conditions where specifying a certain key forces the use of another key.

If you specify...	...must be specified
Device = optical library device	Volume identifier

The following table lists the conditions where specifying a certain key excludes the user from using another key or a particular value of that key.

If you specify...	...cannot be specified
Device = media definition	Optical file Sequence number Volume identifier
Device = optical device	Label Sequence number Use optimum block size
Device = save file	Clear = 2 End of media option Expiration date Label Optical file Sequence number Use optimum block size Volume identifier
Device = tape device	Optical file
Save while active = 0	Save-while-active message queue Save-while-active option

Relationship to SAV Command

Because of the relationship between the QsrSave API and the SAV command, the following situations should be noted:

Message text: Several messages produced by this API refer to parameters or values of the SAV command (for example, *AFTER). To determine which key a given parameter corresponds to, see Valid Keys. To determine which key value a given parameter value corresponds to, see Field Descriptions.
Command type: The command type listed for the API on headings of displays and print files is QsrSave for integrated file system objects. If QsrSave is used to save objects in libraries or document library objects (DLOs), the generated output indicates that the corresponding library or document library objects (DLO) command generated the media.
