Job variable for backup volumes

During the save, FDDRL stores the VSNs of the backup volumes in a job variable. This job variable can then be used to specify the volumes of the last backup when restoration takes place.

You can use this function if you create a job variable with a particular name before the save run. You can also utilize this function without using MAREN.

With one exception, the name of the job variable corresponds to the MAREN file name:

• In the //DUMP-DISK statement you specify the MAREN file name explicitly in the FILE-NAME operand, or when FILE-NAME=*STD is specified FDDRL forms a standard file name.

• In the case of the //DUMP-PUBSET statement, FDDRL forms a standard file name.

If standard names are assigned for the save (see also the chapter "MAREN tape set"), FDDRL expects the job variable under the following name:

• For the single disk save entity

  • FDDRL.D.<vsn_1..6> in //DUMP-DISK

  • FDDRL.P.<catid_1..4>.<vsn_6..6> in the case of //DUMP-PUBSET

• For the disk set save entity

  • FDDRL.D.<vsn_1..6>-1 with the first VSN specified in //DUMP-DISK

  • FDDRL.P.<catid_1..4>-<disk-set-no> in //DUMP-PUBSET
    As an exception to the rule, here the name is not the same as the MAREN file name because the date and time of the backup are not known when the job variable is created.

At the start of the backup, FDDRL deleted the job variable value. The first character in the job variable is “#” if the backup has not been completed or is aborted.
