CICS® VR provides group restore capabilities for backup products which create backups containing data for several data sets.
Some backup products can create a backup for a number of data sets. For example, ABARS can create a backup for an aggregate group, containing data for hundreds data sets. Also, a DFSMSdss DUMP backup can include backups of several data sets.
Variable name | Format | Length (Bytes) | Description | Source |
---|---|---|---|---|
CBUDSN | Char | 44 | Backup data set name. | RCDS |
CBPROD | Char | 3 | Backup product identifier as specified in the backup_product parameter during notification. | RCDS |
CBTYPE | Char | 2 | Backup type identifier as specified in the backup_type parameter during notification. | RCDS |
CBVOLTBL | Char | 8 | Table that contains the volumes on which the backup resides, as entered in the optional volume_list_area parameter during notification. This table can be used to reference each volume using the CBVOL variable. | Generated by CICS VR |
CBVOLNUM | Char | 3 | Number of volumes on which the backup resides, as specified in the optional number_of_volumes parameter during notification. | RCDS |
CBVOL | Char | 6 | Volume on which the backup resides, as specified in the optional volume_list_area parameter during notification. Use this variable with the CBVOLTBL variable to reference each volume name individually. | RCDS |
CBUNIT | Char | 8 | Unit (device type) of the volume(s) on which the backup resides, as specified in the optional device_type parameter during notification. | RCDS |
CBSEQNUM | Char | 4 | Sequence number of the backup, as specified in the optional sequence_number variable during notification. | RCDS |
CBOPTTBL | Char | 8 | Table that contains the value specified for the optional optional_information parameter during notification. The specified optional information can contain a maximum of 256 bytes that CICS VR divides into four rows of 64 bytes in this table. This table can be used to reference each 64 bytes of optional information with the CBINFO variable. | Generated by CICS VR |
CBINFO | Char | 64 | Use this variable with the CBOPTTBL variable to reference each row of 64 bytes of the value specified for the optional optional_information parameter during notification. | RCDS |
CBKSPH | Char | 8 | Table that contains values for dialog variables relating to the VSAM spheres backed up in this backup data set. Each row of the table relates to a specific VSAM sphere and contains all variables listed in Table 1. | Generated by CICS VR |
CNEWN | Char | 3 | Indicates if a new target data set name was entered
through the "CICS VR
panel interface" at least for one VSAM sphere backed in the backup data
set. This variable contains one of the following values:
|
Panel interface |
CNEWV | Char | 3 | Indicates if a new volume and unit was specified
for restore through the CICS VR panel interface for at least one VSAM sphere
backed in the backup data set. This variable contains one of thefollowing
values:
|
Panel interface |
)DOT &CBKSPH
additional statements
)ENDDOT
Any statements between the )DOT and )ENDDOT statements
are processed for each row in the specified table. For example; the following
fragment generates a list of VSAM spheres backed up in the backup data set: )DOT &CBKSPH
&CSPH
)ENDDOT
CICS VR ships two group restore skeletons in the SDWWSENU
data set. These are DWWDS0LD and DWWAB0RS intended for group restoring from DFSMSdss DUMP
or DFSMShsm ABARS
backups accordingly. These skeletons can be used as samples for creating user-written
restore skeletons.
