Output data set option descriptions

You can specify the parameters required for making image copies immediately after an object set has been recovered.

The choices are presented once for each copy type (local site primary, local site backup, recovery site primary, recovery site backup).

The fields are listed alphabetically in the following table along with the corresponding BMC AMI Recovery Manager defaults.

Field

Default

Description

Allocation type

Cylinder

Specifies whether the primary and secondary allocations quantities are expressed in cylinders or tracks

This option does not apply to tape units.

Catalog

Yes

Catalogs the data sets in the operating system catalog

Data set name

BMC AMI Recover by part

&USERID.&DB.&TS.&TYPE&DATE.T&TIME

&USERID.&DB.&TS.&TYPE&DATE

Specifies the name of the disk or tape data set for the current copy type

You can use symbolic variables to construct this name (see Subsystem-toolbox). Generation data object sets are not allowed.

The data set specification is in two parts. The first part is applicable to all recover utilities. The second part is used only when BMC AMI Recover is the recovery utility.

The specified data set name is used as a prefix to which is appended the partition number in the form Ann (the number at the end of the data set name in the VSAM catalog).

Important

The data set specified in the BMC Recover by part field is only used when making copies by partition after a recovery using the BMC AMI Recover OUTCOPY feature when the object set is defined as DSNUM=0. All other output is sent to the data set specified in the Data set name field.

EATTR for EAV

Keyword:

EATTR

Not specified

Specifies whether a data set supports extended attributes or not. Specifying no value for EATTR allows the value for EATTR to be set by an SMS DATACLAS. Valid values are:

  • OPT—specifies that extended attributes are optional for the data set.

You must set OPT to allocate an extended format sequential data set. By using OPT, BMC AMI Recover supports sequential data sets in the cylinder-managed portion of EAVs.

Extended format sequential data sets must be allocated on SMS-managed volumes and the size of the data set must be greater than the EAV break point, which is typically 10 cylinders.

  • NO—specifies that the data set cannot have extended attributes.

Expiration date

1999/000

Specifies the expiration date for a tape copy data set

The date must be in the format yyyy/ddd. The BMC AMI Recovery Manager default is 1999/000, which indicates no expiration.

Max primary allocation

0

Limits the amount of primary allocation space to be used for the output copy data sets made to DASD using DSNUTILB COPY or BMC AMI Copy

Valid values are 0 - 9999, where 0 indicates no limit.

BMC AMI Recovery Manager compares the maximum primary allocation to the calculated primary allocation value and selects the smaller of the two. If the maximum primary value is selected, the primary space allocation is set to that value and the secondary space allocation is set to 1/15 of that value.

Max primary allocation (continued)


Max primary allocation affects the following values:

  • Primary Allocation, Dynamic Sortworks, and WORKDDN Sizing

    BMC AMI Recover compares the maximum primary allocation to the calculated primary allocation value and selects the smaller of the two. If the maximum primary value is selected, the primary space allocation is set to that value, and the secondary space allocation is set to 1/15 of that value. The same calculations are used for the sort work files.

  • Unit Count (for DSNUTILB COPY)

    The unit count for DSNUTILB COPY is based on the maximum primary value. If the space required for the copy is greater than the maximum primary allocation, BMC AMI Recovery Manager calculates the required unit count. The unit parameter is UNIT=(workUnit,n) where n is the calculated number of units up to a maximum of 59. If the maximum primary value is 0, no unit count is calculated. (See BMC-AMI-Copy-backup-options.)

    You must ensure that you use a maximum primary value that fits on your DASD devices. If the maximum primary value exceeds the capacity of a volume, the job will fail. See Work-file-option-descriptions for the capacity of typical DASD devices.

Model data set name (DCB)

None

Specifies the fully qualified name of a cataloged data set to define the model data control block (DCB)

Primary allocation

10

Specifies the primary allocation quantity (disk only)

Use this option only when BMC AMI Recovery Manager is unable to estimate the quantity or when the Data Set Sizing option is set to Default.

Important

This value is used when you make copies using DSNUTILB COPY or when you use BMC AMI Copy to make CABINET copies to disk. It is ignored when you use BMC AMI Copy to make any other type of copy because BMC AMI Copy performs its own data set sizing.

Retention period

0

Specifies the tape copy data set retention period in days

The valid range is 1 through 999. Retention period and Expiration date are mutually exclusive.

Secondary allocation

20

Specifies the secondary allocation quantity (disk only)

Use this option only when BMC AMI Recovery Manager is unable to estimate the quantity or when the Data Set Sizing option is set to Default.

Important

This value is used when you make copies using DSNUTILB COPY or when you use BMC AMI Copy to make CABINET copies to disk. It is ignored when you use BMC AMI Copy to make any other type of copy because BMC AMI Copy performs its own data set sizing.

SMS data class

Null

Specifies a valid SMS data class name for disk data sets

The name must not exceed 8 characters. BMC AMI Recovery Manager forces Catalog Yes when this option is specified.

SMS management class

Null

Specifies a valid SMS management class name for disk data sets

The name must not exceed 8 characters. BMC AMI Recovery Manager forces Catalog Yes when this option is specified.

SMS storage class

Null

Specifies a valid SMS storage class name for disk data sets

The name must not exceed 8 characters. BMC AMI Recovery Manager forces Catalog Yes when this option is specified.

Stack (copies on tape)

No

Specifies whether to stack image copies of the same type contiguously on the same tape

Used in conjunction with the Tape option.

For Recovery Management for Db2 solution only - you can specify Cabinet to create cabinet copies. Cabinet copies can be made to either disk or tape. For more information, see the Recovery Management for Db2 documentation

Tape

No

Specifies that the unit is a tape when you respond Yes and when you also provide the name of the tape unit at the Unit prompt. Responding No specifies a disk.

Important

If you provide a unit name and leave Tape blank, you will receive an INVALID COMBINATION message.

Unit

SYSALLDA

Specifies the name of the disk or tape unit to which the image copy data sets will be written

Vol count

0

Specifies the largest number of tape volumes that are expected to be created

The valid range is 1 through 255. This option applies only to tape data sets. You can leave this field blank if you expect not more than five tape volumes will be created.
