z/OS V1R6.0 DFSMS Access Method Services for Catalogs

BLDINDEXRECOVERYSPEEDWRITECHECK5. When all alternate index records are built and loaded into the alternate index,the alternate index and its base cluster are closed. Steps 1 through 4 arerepeated for each alternate index that is specified with the OUTFILE andOUTDATASET parameter. When all alternate indexes are built, any definedexternal sort work files are deleted. Access method services finishes processingand issues messages that show the results of the processing.DD Statements That Describe the Sort Work FilesVSAM data set space available for the sort routine can be identified by specifyingtwo ddnames with the WORKFILES parameter and supplying two DD statementsthat describe the work files to be defined. Each work file DD statement should becoded://ddname DD DSNAME=dsname,VOL=SER=volser,// UNIT=devtype,DISP=OLD,AMP=’AMORG’Exception: WORKFILES is ignored when DFSORT is available to do the sorting ofthe alternate index and you have not overridden the default by specifyingNOSORTCALL.ddnameas specified in the WORKFILES parameter. If you do not specify theWORKFILES parameter and you intend to provide VSAM data set space forexternal sort work files, identify the work file DD statements with the namesIDCUT1 and IDCUT2.dsnamea data set name. The scheduler generates a data set name for the work file ifnone is provided. The data set will be cataloged into the master catalog unlessa STEPCAT or JOBCAT is specified and deleted when BLDINDEX processinghas completed. A data set name must be specified if the user, or the user’sgroup, is defined to RACF with the automatic data set protection (ADSP)attribute. The first qualifier of the data set name must be a valid user or groupname.Restriction: JOBCAT and STEPCAT DD statements are disabled, by default,during installation. If you use JOBCAT or STEPCAT DD statements, see theinformation in “JCL JOBCAT and STEPCAT DD Statements” on page 4.VOL=SER=volserRequired. Identifies the volume owned by the STEPCAT, JOBCAT, or mastercatalog where the work file is cataloged. The work file’s space is allocated fromthe volume’s space. You can specify a maximum of five volumes for each workfile. For a description of how to calculate the amount of space to be allocatedfor each sort work file, see Chapter 8, “BLDINDEX,” on page 91. If yourBLDINDEX job requires external sort work files, this space must be availableon the volume(s) identified by volser or your job will fail.UNIT=devtypetype of direct access device on which the volume is mounted. You can specifya generic device type (for example, 3380) or a device number (for example121). You cannot specify SYSDA.DISP=OLDRequired.96 z/OS V1R6.0 DFSMS Access Method Services for Catalogs
