5 Error code I/O Char(*)

  Default Public Authority: *USE

  Threadsafe: No

The Retrieve Backup Options (QEZRTBKO) API returns in a receiver variable the backup options for the requested backup type. If you request all options, the receiver variable contains the header, which is followed by three RBKO0100 formats, one for each backup type.

Required Parameter Group

Receiver variable
OUTPUT; CHAR(*)

The receiver variable that receives the information requested. You can specify the size of the area to be smaller than the format requested as long as you specify the length parameter correctly. As a result, the API returns only the data that the area can hold.

Length of receiver variable
INPUT; BINARY(4)

The length of the receiver variable provided. The length of receiver variable parameter may be specified up to the size of the receiver variable specified in the user program. If the length of receiver variable parameter specified is larger than the allocated size of the receiver variable specified in the user program, the results are not predictable. The minimum length is 8 bytes.

Format name
INPUT; CHAR(8)

The format of the backup option descriptions to be returned. The valid format names are RBKO0100 and RBKO0200.

RBKO0100 This format returns information about what the user has selected to be saved on the next backup for that type (*DAILY, *WEEKLY, or *MONTHLY).
RBKO0200 This format returns information on the last backup date and time, and when the next backup date and time for that backup option are scheduled to occur.

Backup option
INPUT; CHAR(10)

The backup options to retrieve. Possible values follow:

*DAILY Daily backup options.
*WEEKLY Weekly backup options.
*MONTHLY Monthly backup options.
*ALL The backup options for all types of backup (*DAILY, *WEEKLY, and *MONTHLY).
Error code
I/O; CHAR(*)

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