Issue/Introduction

Ways to control execution of the View Interim backup process.

Resolution

A) The SARINIT parameters that control the interim backup are:

NBACKUP and INTERVAL

Where...

NBACKUP
This parameter specifies the number of interim backups done during the time specified with the INTERVAL initialization parameter. These backups do not cause the generation number to be incremented. The backups are executed at equal intervals within this time.

Syntax:
NBACKUP=nnnnn
The default is 0. Valid values are 0-32767.
To determine the time spacing between interim backups, add 1 to the NBACKUP number and then divide that number into the INTERVAL number.

Note: You can perform interim backups by specifying the NBACKUP initialization parameter. Automatic interim backups are dependent on the standard backup. If no standard backup is performed, TBACKUP=NO, or DAYS=NNNNNN, no interim backups are performed.

INTERVAL
This parameter specifies the time interval in hours and minutes after which the backup cycle is automatically initiated. A value of 0000 is converted to the default of 2400, which is the maximum value for this parameter.

Syntax:
INTERVAL=hhmm
The default is 2400.
Values are as follows:
hh The hour, based on a 24-hour clock.
mm The minutes.
Valid values for hh are 00-24. Valid values for mm are 00-59.
The maximum value that can be specified is 2400 (the default):

Note: For more information about this parameter, see the TIME command later in this chapter.

B) You can optionally issue MODIFY and/or START operator commands to initiate/force the interim backup.

- Modify command to initiate an interim backup:

/F SARSTC,?????   (specify INEW or IDUMP)

or

- Start command to initiate an interim backup:

S SARSTC,OPT=?????

Where...

OPT=IDUMP
Specifies that an interim backup cycle is initiated immediately following initialization and before archiving any SYSOUT
This backup resides on the same tape as the previous backup, provided the tape has room, because the archival generation number is not incremented. (Also, an initialization parameter, MAXGENT, specifies the maximum number of generations that are written to one tape.)

OPT=INEW
Specifies that the archival task initiates an interim backup cycle immediately following initialization and before archiving any SYSOUT
The archival generation number is not incremented; however, this backup resides on a new tape.
