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

BLDINDEXnames for the work file DD statements, you must identify those DDstatements with the WORKFILES parameter.Abbreviation: ESORTINTERNALSORTrequires access method services to sort the key-pointer pairs entirely withinthe user-provided virtual storage, if possible. If you do not have enoughvirtual storage available when you use INTERNALSORT, two external-sortwork files are built and the key-pointer pairs are sorted externally. Youmust provide DD statements as for EXTERNALSORT. If the minimumamount of virtual storage is not provided the BLDINDEX processing endswith an error message. See z/OS DFSMS: Using Data Sets for moreinformation about alternate indexes.Abbreviation: ISORT{SORTCALL|NOSORTCALL}use this parameter to choose whether or not to call DFSORT to sort thealternate index.SORTCALLspecifies that you want DFSORT to sort the alternate index.EXTERNALSORT, INTERNALSORT, WORKFILES, CATALOG, IDCUT1,and IDCUT2 are ignored when DFSORT is called. If DFSORT is notavailable, BLDINDEX uses the IDCAMS internal sort. SORTCALL is thedefault.NOSORTCALLtells BLDINDEX to use the IDCAMS internal sort (or external sort ifspecified) instead of DFSORT to sort the alternate index. When theIDCAMS internal or external sort is used, SORTMESSAGELEVEL,SORTDEVICETYPE, SORTMESSAGEDD and SORTFILENUMBERspecifications are prohibited.SORTDEVICETYPE(device type)specifies the DASD device type passed to DFSORT in the DYNALLOCparameter in the OPTION control statement. Use this parameter only if youwish to override the default device type for DFSORT work data sets. See z/OSDFSORT Application Programming Guide for further details on the DYNALLOCparameter. This parameter is not allowed if you use NOSORTCALL.Abbreviation: SORTDVT SDVTSORTFILENUMBER(number)the maximum number of work data sets passed to DFSORT in theDYNALLOC parameter in the OPTION control statement. Use this parameterto override the number of work data sets that BLDINDEX determines areneeded. See z/OS DFSORT Application Programming Guide for further details onthe DYNALLOC parameter. This parameter is not allowed if you useNOSORTCALL.Abbreviation: SORTFN SFNSORTMESSAGEDD(ddname)is the ddname that describes the DFSORT message data set. If there is no DDstatement for this ddname, a message data set with this ddname is allocateddynamically as a SYSOUT=* data set. SYSOUT is the default for ddname. Donot use any ddname reserved for use by IDCAMS (SYSPRINT or SYSIN) orChapter 8. BLDINDEX 93
