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

EXPORTOUTFILE(ddname)Specifies the name of the DD statement of the target data set.Only the block size for the DCB parameter should be specified in the DDstatement. The default for block size for EXPORT is 2048. Block size can begiven in the DD statement to override this default and improveperformance.Exception: For a nonlabeled tape, the LRECL should be specified if any ofthe input records are greater in size than the block size. Maximum recordsize is determined by the value specified with the maximum subparameterof the RECORDSIZE parameter of the DEFINE CLUSTER or DEFINEALTERNATEINDEX command when the data set was defined.Abbreviation: OFILEOUTDATASET(entryname)Specifies the name of the target data set. If OUTDATASET is specified, anattempt is made to dynamically allocate the target data set. Thecharacteristics of the target data set are described in “JCL DD Statement fora Target Data Set” on page 4.If OUTDATASET specifies an SMS-managed data set, the exported data setmust either be an SMS-managed data set, or a non-SMS-managed data setcataloged in the catalog determined by the catalog search order. Forinformation about this search order see “Order of Catalog Use” on page 9.Abbreviation: ODSOptional ParametersCIMODE|RECORDMODESpecifies whether control interval processing (CIMODE) or logical recordprocessing (RECORDMODE) is to be used to export the records of the data setcluster. RECORDMODE is the default for ESDS, KSDS, and RRDS clusters.CIMODE is the default for LDS clusters.250 z/OS V1R6.0 DFSMS Access Method Services for CatalogsCIMODESpecifies that the cluster data records written to the portable data set areprocessed as one VSAM control interval. You can use CIMODE processingto export data sets more quickly. Each control interval is processed as onelogical record.If control interval processing is used, the target data set’s catalog entry willnot have correct statistics. These statistics are correctly updated the firsttime the data set is opened for output.When you use control interval processing to export an ESDS cluster thatcontains an alternate index, logical record processing is used, and awarning message is issued.IMPORT will determine the type of processing (control interval or logicalrecord) used by EXPORT to process the cluster data records, and use thesame processing type for loading. Thus, a data set that was exported incontrol intervals is loaded in control intervals. Similarly, a data setexported in logical records is loaded by IMPORT as VSAM logical records.The CIMODE portable data set created by the EXPORT command is notcompatible with a CIMODE portable data set created on a VSE system.Therefore, any attempt to import an object exported on a VSE system withcontrol interval processing support is not detected by IMPORT and givesunpredictable results.
