Sample MERGECOPY control statements

Use the sample control statements as models for developing your own MERGECOPY control statements.

Example 1: Creating a merged incremental copy

The control statement in this example specifies that the MERGECOPY utility is to merge incremental image copies from table space DSN8S12C into a single incremental image copy. The NEWCOPY NO option indicates that these incremental copies are not to be merged with the full image copy. The COPYDDN option specifies that the output image copies are to be written to the data sets that are defined by the COPY1 and COPY2 DD statements.

//STEP1    EXEC DSNUPROC,UID='IUJMU107.MERGE1',
//          UTPROC='',SYSTEM='DSN'
//COPY1  DD DSN=IUJMU107.MERGE1.STEP1.COPY1,DISP=(MOD,CATLG,CATLG),
//          UNIT=SYSDA,SPACE=(4000,(20,20),,,ROUND)
//COPY2  DD DSN=IUJMU107.MERGE1.STEP1.COPY2,DISP=(MOD,CATLG,CATLG),
//          UNIT=SYSDA,SPACE=(4000,(20,20),,,ROUND)
//SYSUT1   DD DSN=IUJMU107.MERGE1.STEP1.SYSUT1,DISP=(MOD,DELETE,CATLG),
//          UNIT=SYSDA,SPACE=(4000,(20,20),,,ROUND)
//SYSIN    DD *
MERGECOPY TABLESPACE DSN8D12P.DSN8S12C
  COPYDDN      (COPY1,COPY2)
  NEWCOPY  NO

Example 2: Creating merged incremental copies and using template switching

Each MERGECOPY control statement in the following example specifies that MERGECOPY is to merge incremental image copies from the specified table space into a single incremental image copy for that table space. For each control statement, the COPYDDN option specifies that the output image copies are to be written to data sets that are defined by the T1 template. The T1 template has specified the LIMIT option. This means that the output image copies are to be written to DASD, if the output image copy size is less than 5 MB. If the limit is exceeded, template switching from template T1 to template T5 takes place and the output image copies are to be written to TAPE. This template is defined in the TEMPLATE utility control statement.

//STEP1    EXEC DSNUPROC,UID='JULTU224.MERGE',                            
//         UTPROC='',                                                     
//         SYSTEM='SSTR'                                                  
//SYSUT1   DD DSN=JULTU224.MERGE.STEP1.SYSUT1,DISP=(MOD,DELETE,CATLG),
//         UNIT=SYSDA,SPACE=(4000,(20,20),,,ROUND)
//SYSIN    DD *                                                           
  TEMPLATE T1 UNIT(SYSDA) SPACE CYL                                                 
              DSN(T1.&SN..T&TI..COPY&IC.&LOCREM.)			                 
              LIMIT(5 MB,T5)				                                      
  TEMPLATE T5 UNIT(3BO)                                      
              DSN(T5.&SN..T&TI..COPY&IC.&LOCREM.)			                 
  MERGECOPY TABLESPACE DBLT2401.TPLT2401 DSNUM ALL NEWCOPY NO             
          COPYDDN(T1)                                                     
  MERGECOPY TABLESPACE DBLT2401.TLLT24A1 DSNUM ALL NEWCOPY NO             
          COPYDDN(T1)                                                     
  MERGECOPY TABLESPACE DBLT2401.TLLT24A2 DSNUM ALL NEWCOPY NO
          COPYDDN(T1)                                                      
  MERGECOPY TABLESPACE DBLT2401.TLLT24A3 DSNUM ALL NEWCOPY NO              
          COPYDDN(T1)                                                      
  MERGECOPY TABLESPACE DBLT2401.TLLT24A4 DSNUM ALL NEWCOPY NO              
          COPYDDN(T1)

Example 3: Creating a merged full image copy

The following MERGECOPY statement example specifies that the utility is to merge all incremental image copies with the full image copy from table space DSN8S12C to create a new full image copy.

//STEP1    EXEC DSNUPROC,UID='IUJMU107.MERGE2',
//          UTPROC='',SYSTEM='DSN'
//COPY1  DD DSN=IUJMU107.MERGE2.STEP1.COPY1,DISP=(MOD,CATLG,CATLG),
//          UNIT=SYSDA,SPACE=(4000,(20,20),,,ROUND) 
//COPY2  DD DSN=IUJMU107.MERGE2.STEP1.COPY2,DISP=(MOD,CATLG,CATLG),
//          UNIT=SYSDA,SPACE=(4000,(20,20),,,ROUND) 
//SYSUT1   DD DSN=IUJMU107.MERGE2.STEP1.SYSUT1,DISP=(MOD,DELETE,CATLG),
//          UNIT=SYSDA,SPACE=(4000,(20,20),,,ROUND)
//SYSIN    DD *
MERGECOPY TABLESPACE DSN8D12P.DSN8S12C
  COPYDDN      (COPY1,COPY2)
  NEWCOPY  YES

Example 4: Using MERGECOPY with CLONE keyword

The following control statement specifies that MERGECOPY is to process only image copy data sets that were taken against clone objects.

MERGECOPY TABLESPACE DBIQUD01.TPIQUD01 DSNUM ALL CLONE NEWCOPY YES 
         COPYDDN(COPYTB1)
