The DWWRUNBL job

The DWWRUNBL job updates the sample VSAM cluster created by the DWWVRDEF IVP job.

Before running the DWWRUNBL job, enter this command D SMS,CICSVR to ensure that the CICS VR server address space is activated successfully. The output from the D,SMS,CICSVR command is similar to this:

DWW020I DISPLAY SMS,CICSVR

Run the DWWRUNBL job from your customized SDWWCNTL.OUT data set. If you have not performed customization, copy member DWWRUNBL from data set SDWWCNTL and only modify the SETPARM statement using the THLQ DWWUSER.V610. This example shows the first part of the JCL used to submit the job:


//*-------------------------------------------
//SETPARM  SET THLQ=DWWUSER.V610                       
//*-------------------------------------------
//* Load Vsam data sets                       
//*-------------------------------------------
//LOAD     EXEC PGM=IDCAMS                    
//OUTFILE1 DD  DISP=SHR,                      
//             DSN=&THLQ..CUSTOMER            
//OUTFILE2 DD  DISP=SHR,                      
//             DSN=&THLQ..CUSTOMER.NEW        
//SYSPRINT DD  SYSOUT=*

When you submit the DWWRUNBL job the output, which is similar to the screen shot below, is saved in the JES2 job log. Look for message DWW264I in the output to confirm that VSAM batch REDO logging completed successfully.

Make a note of the time that the DWWRUNBL job is started because this time must be specified as the forward recovery start time during the CICS VR ISPF dialog interface as described in DWWCLIST - ISPF dialog interface.

Note: The VSAM dataset has to be SMS managed for batch logging to work.
