TOSIDBR control statement

The TOSIDBR control statement issues the /DBRECOVERY (/DBR) command of IMS™ for each index to be built before the build process starts.

Requirement: The command is issued by using the IMS Tools Online System Interface. To specify the TOSIDBR control statement, you must also specify the TOSIXCFGRP control statement.

TOSIDBR: Specifies that this is a TOSIDBR statement.
NO: IMS Index Builder does not issue /DBR commands.
YES: IMS Index Builder issues /DBR commands.

The following keywords specify the parameters that are issued with the /DBR commands.

LOCAL: The /DBR command is issued to each IMS subsystem that belongs to the XCF group of the IMS Tools Online System Interface.
GLOBAL: The /DBR command is issued with the GLOBAL keyword to one of the IMS subsystems that belongs to the XCF group.
NOPFA: The NOPFA parameter is specified on all /DBR commands, which means that the Prohibit Authorization flag in the RECON data set is not set.
NOFEOV: The NOFEOV parameter is specified on all /DBR commands.
LASTFEOV: The NOFEOV parameter is specified on all /DBR commands except for the last one.
FEOV: The NOFEOV parameter is not specified on the /DBR commands.

For more information about the /DBR command and its parameters, see the topic "/DBRECOVERY command" in IMS Commands.

If this statement is not specified, NO is the default. If only TOSIDBR YES is specified, TOSIDBR YES,LOCAL,NOFEOV is used.

For a HALDB, if the BLD_PRIMARY, BLD_ILDS, or BLD_ALL keyword is specified on the PROC control statement and TOSIDBR YES is specified, the /DBR command is issued for the HALDB master database. If a list of partition names is provided on the PARTNAME control statement, the /DBR command is issued for each HALDB partition in the list instead of the HALDB master database.

For each PSINDEX to be built, the /DBR command is issued for the PSINDEX master database. If a list of partition names is provided on the INDEX control statement, the /DBR command is issued for each PSINDEX partition in the list instead of the PSINDEX master database.

Tip: You can override the default value in the runtime parameters module. See the explanation of the IIURDFLT TOSIDBR entry in Defining runtime parameters.
