Example 11: Recovering using a change accumulation file

This example illustrates the creation and use of change accumulation files in the recovery of a table space. An index on the table in the table space is also rebuilt.

Example 11A: Creating the change accumulation file

The JCL in the following figure creates the change accumulation file.

JCL using R+/CHANGE ACCUM to accumulate log records

//AFREX13A JOB (PAFR),'EXAMPLE 11A', 
//         class="Q",NOTIFY=&SYSUID, 
//         MSGCLASS=X 
//* 
//RECOVER EXEC PGM=AFRMAIN,REGION=0M, 
//             PARM='DEBA,EXAMPLE11A,NEW/RESTART,MSGLEVEL(2)' 
//STEPLIB  DD DISP=SHR,DSN=product.libraries
//          DD DISP=SHR,DSN=DB2.DSNEXIT
//          DD DISP=SHR,DSN=DB2.DSNLOAD
//SYSIN     DD * 
 ACCUM GROUP BMCSMPGP 
/* 
//

Example 11B: Using the change accumulation file

The JCL in the following figure recovers the table space using the change accumulation file created in Example 11A.
