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

IMPORTImport a Catalog: Example 2In this example, a catalog, USERCAT4, that was previously exported, is imported.(See the EXPORT example, “Export a Catalog: Example 1” on page 253.) Theoriginal copy of USERCAT4 is replaced with the imported copy, from the portablefile copy in CATBACK. Access method services finds and deletes the duplicatename, USERCAT4. Any aliases in the master catalog for USERCAT4 are preserved.(A duplicate name exists because the catalog was exported with the TEMPORARYattribute.) Access method services then redefines USERCAT4, using the cataloginformation from the portable file, CATBACK. USERCAT4 is locked to preventaccess to anyone except authorized recovery personnel.Requirement: Before you can lock a catalog, you must have read authority to theprofile name, IGG.CATLOCK, with class type FACILITY.//IMPRTCAT JOB ...//STEP1 EXEC PGM=IDCAMS//SOURCE DD DSNAME=CATBACK,UNIT=3390,// VOL=SER=327409,DISP=OLD//SYSPRINT DD SYSOUT=A//SYSIN DD *IMPORT -INFILE(SOURCE) -OUTDATASET(USERCAT4) -ALIAS -LOCK -CATALOG(ICFMAST1)/*Job control language statement:vSOURCE DD describes the portable data set, CATBACK.The IMPORT command copies the portable data set, CATBACK, into the system.Access method services reorganizes the data records so that deleted records areremoved and control intervals and control areas contain the specified free spacepercentages. The original copy of the cluster is deleted and replaced with the datarecords from the CATBACK portable file. The IMPORT command’s parameters are:v INFILE points to the SOURCE DD statement.vvvvOUTDATASET gives the name of the catalog being imported. Access methodservices dynamically allocates the catalog.ALIAS specifies that aliases that already exist in the master catalog forUSERCAT4 are to be preserved and that the aliases on the portable file are to belisted. However, if USERCAT4 had not existed in the system when importing,the aliases on the portable file would have been defined for USERCAT4.LOCK specifies that the catalog being imported is locked.CATALOG identifies the master catalog, ICFMAST1.Import a Key-Sequenced Cluster: Example 3In this example, a key-sequenced cluster, BCN.EXAMPLE.KSDS1, that waspreviously exported, is imported. (See the EXPORT example, “Export aKey-Sequenced Cluster: Example 2” on page 254.) OUTFILE and its associated DDstatement are provided to allocate the data set.The original copy of BCN.EXAMPLE.KSDS1 is replaced with the imported copy,TAPE2. Access method services finds and deletes the duplicate name,BCN.EXAMPLE.KSDS1, in the catalog, VCBUCAT1. (A duplicate name existsbecause TEMPORARY was specified when the cluster was exported.)
