INDEPENDENT OUTSPACE specification for IMPORT

You can preallocate the INDEP OUTSPACE data sets using the following guidelines:

• For VCAT-defined spaces, ensure that the volumes or space allocated is large enough to hold the data set.
• If the target space is defined using a STOGROUP, and if primary and secondary quantities are not defined for the source space, BMC AMI Recover uses a sliding-scale calculation for secondary extents, similar to the method Db2 uses.

For more information, see Primary space allocation and Secondary extents.

You can allow BMC AMI Recover to dynamically allocate the INDEP OUTSPACE data sets for STOGROUP-defined spaces. If the INDEP OUTSPACE data set does not exist, BMC AMI Recover uses the attributes of the source space to dynamically allocate the target INDEP OUTSPACE data set. If the INDEP OUTSPACE data set exists, BMC AMI Recover uses it as is (no DELETE or DEFINE executed).

BMC AMI Recover includes support for multi-data-set spaces. For example, BMC AMI Recover will dynamically allocate A002, and A003, to A00n INDEP OUTSPACE data sets as needed.

To have BMC AMI Recover dynamically allocate the INDEP OUTSPACE data set on a specific volume or volumes, pass a volume list by using the STOGROUP...USEORDER specification in the OPTIONS statement (see STOGROUP-specification-description). BMC AMI Recover statements that use STOGROUP... USEORDER are shown in the following example:

The default model name is identical to the Db2 name of the object being recovered, but with BMCDBC substituted for DSNDBC in the CLUSTER portion of the VSAM data set:

vcat.BMCDBC.databaseName. objectName.p0001.znnn

The variables are defined as follows:

• vcat is the ICF catalog name.
• databaseName.objectName is the name of the database and object containing the data set being recovered.
• p corresponds to the value that is used by Db2 for this node.

• znnn is the data set number.

  z represents the letter A, B, C, D, or E. These letters correspond to the first digit—0, 1, 2, 3, or 4—of the partition number. nnn represents the rest of the partition number. znnn represents the partitions numbers as follows:

  • A001 through A999 for partitions 1 through 999
  • B000 through B999 for partitions 1000 through 1999
  • C000 through C999 for partitions 2000 through 2999
  • D000 through D999 for partitions 3000 through 3999
  • E000 through E096 for partitions 4000 through 4096

When you want to specify a name of your own choosing, use the MODEL option to specify the name of the CLUSTER portion of the VSAM data set that you want to use. The data set name that you specify might include any of the symbolic variables that are listed in the description of the MODEL keyword in the following section.

When you use INDEP OUTSPACE, you must specify it after the object specification.
