Optional control statements

Use the optional control statements of IMS Index Builder to control the behavior of an IMS Index Builder job.

CLASS control statement
IMS Index Builder uses data sets to pass data between the sort, scan, and master address spaces. These data sets exist only for the duration of the run. By default, they are allocated with the high-level qualifier IIU.STRIPE. The CLASS control statement can be used to specify a different high-level qualifier.
COMPAUTH control statement
The COMPAUTH control statement specifies whether the segment compression routine is called in supervisor state.
DBAUTH control statement
The DBAUTH control statement specifies whether IMS Index Builder issues the IMS DBRC authorization request for the prime database and the indexes to prevent transactions and programs from updating the database.
DFSDF control statement
The DFSDF control statement specifies the suffix of the DFSDFxxx member in the IMS.PROCLIB data set. The member with this suffix must exist in a data set specified in the PROCLIB DD statement. If the member contains the ACBMGMT=CATALOG parameter in the <CATALOG> section, IMS managed ACBs is enabled.
IIURSORT control statement
The IIURSORT control statement specifies the procedure name to start SORT and SCAN subordinate address spaces. By default, the IIUBSRT procedure is used.
ILDS control statement
The ILDS control statement specifies whether to build ILE records or to initialize the data set without building any ILE records in the ILDS build process.
INDEX control statement
The INDEX statement specifies the name of one or more secondary index databases to be recovered or built.
ITKBLOAD control statement
The ITKBLOAD control statement specifies the name of the load module library for IMS Tools Knowledge Base. This control statement is used only when ITKBSRVR control statement is specified.
ITKBSRVR control statement
The ITKBSRVR control statement specifies the XCF group name of the IMS Tools Knowledge Base server where the IMS Index Builder reports are to be stored and viewed.
JOBNSCAN control statement
The JOBNSCAN control statement specifies the job name of each SCAN subordinate address space, which is started when the sequential scan method is used for HALDB partitions. By default, the IIUSCANS is used for the job name.
JOBNSORT control statement
The JOBNSORT control statement specifies the job name of each SORT subordinate address space. By default, IIUSORTS is used for the job name.
MAXTASKS control statement
The MAXTASKS control statement is used to customize the IMS Index Builder run.
OUTPUT control statement
The OUTPUT control statement specifies the DD name that is used for output.
PARTNAME control statement
The PARTNAME control statement specifies one or more HALDB (PHDAM or PHIDAM) partitions to be processed.
PROGMON control statement
The PROGMON control statement specifies the interval for issuing WTO IIUB119I messages, which are messages to indicate the progress of the load process for each secondary index.
SIDXBUF control statement
The SIDXBUF control statement specifies the number of buffers that are to be used in the load process for each secondary index.
SORTFSZ control statement
The SORTFSZ control statement selects striped sort mode or specifies large sort volumes for sequential scan. SORTFSZ will trigger striped sort mode, the value that is entered will be used to determine the size of the sort stripes.
SORTOPT control statement
The SORTOPT statement specifies SORT parameters to be appended to the SORT OPTION statement of all the sorts that are started by an IMS Index Builder job.
STRIPE control statement
The STRIPE control statement specifies the UNIT value and the volume count for allocating stripe data sets.
SVCDUMP control statement
The SVCDUMP control statement specifies whether IMS Index Builder requests an SVC dump file after a system abend or a user abend.
TMRWAIT control statement
The TMRWAIT control statement specifies the IIUTMRXT timeout value in seconds.
TOSIDBD control statement
The TOSIDBD control statement issues the /DBDUMP (/DBD) command of IMS for the prime database before the scan process starts.
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.
TOSISTA control statement
The TOSISTA control statement issues the /START (/STA) command of IMS for the prime database and each index after the build process.
TOSIWAIT control statement
The TOSIWAIT control statement specifies the IMS Tools Online System Interface response timeout value.
TOSIXCFGRP control statement
The TOSIXCFGRP control statement specifies the XCF group name for the IMS Tools Online System Interface.
VIC control statement
The VIC control statement specifies whether IMS Index Builder issues the DBRC NOTIFY.UIC command to turn off the IC NEEDED flag.
WFPDEL control statement
The WFPDEL control statement specifies whether IMS Index Builder deletes the WFP data sets after loading indexes.
WFPHLQ control statement
The WFPHLQ control statement specifies the high-level qualifier of the WFP data sets that were generated by IMS High Performance Load.
ZIIPMODE control statement
The ZIIPMODE control statement specifies whether IMS Index Builder offloads eligible workloads to zIIP processors.
