I have a lot of files that we have to capture for 10 days. The total space required would be around 1500 GB of data. The storage managment are not very comfortable in giving so much of space together. Hence I was advised that I store some of the files to tapes. But everytime I need these files I need to get them back from TAPE. I am not sure how does this work. Do I have to create new Jobs to get all the files from TAPE or do I ask the storage management to restore all the the files from a particular volume.
Thanks,
Megana

Megana,

You may not have to do any changes to your JCL.

1. If the dataset information (volume serial....) is updated in Catalog then You don't have to worry about changing any of your JCLs. Just read the dataset as if it is in DASD. The only difference would be that the job will take longer time to complete. (To check the catalog entry, just see if you are able to find the tape dataset in 3.4 with volume serial).

2. If you don't see the dataset in 3.4 panel that means that the tape volume information is not in catalog. In this case, you must change your JCL as shown below.

Code:

//STEPxx   EXEC  ......
//ddname1    DD  DSN=my.tape.input.file1,
//                DISP=SHR,VOL=SER=(volume1, volume2, volume3....)
//ddname2    DD  DSN=my.tape.input.file2,
//                DISP=SHR,VOL=SER=(volume11,volume12,volume13....)
.....


Thanks,
Phantom
