Can anybody tell how the background application works

Like HRECALL is an utility which will recall the migrated datasets. How it could be done

Thanks,

Hi Ugandar,

A background Job will be submitted if you type HRECALL against a dataset name, Correct me if i am wrong.

Thanks
Sai

No, a background job will not be submitted if you type HRECALL against a dataset. HRECALL is a HSM subsystem command which can be entered from any active TSO session, either at the terminal, in batch, or when a process detects that a dataset to be opened is migrated.

You can load your HRECALL statements into a dataset and either submit a batch TSO session to process them, or just type EX next to the dataset in 3.4

Hi,

Now, I'm bit confused here, according to expat 'no JOB'll be submitted when one use HR or EX' , while JCL posted by 'sai' is working for me.

JCL from 'sai' & commands 'HR & EX' have some relation in them or are they totally different altogther? If they have nothing to do with each other, then what happens at system level when one issue the command 'HR or EX' ?

Please advise.

Hello,

I believe HR and EX are extensions or aliases for HRECALL. They are site specific. They (as well as HRECALL) can run online.

The JCL provided is if someone wants to do the recall in batch and not from the terminal.

Anuj,

The example shown is a batch TSO session, PGM=IKJEFT01, so you will need to submit the job for it to run. This is just a batch version of issuing the HRECALL command in 3.4, but is useful when you have many recalls to process.

You could put all of your HRECALL commands into a dataset and in 3.4 just type EX (EXECUTE) against it, and that will be the same as you sitting there doing a HRECALL against each dataset individually.

I believe that EX is a universal command, which works against PDS members or PS datasets. It's worked at every shop that I have.

Thank you very much saiprasad...

Actually what iam going to do is I have to do string search in all the members of a pds

In normal mainframe itself we are having 3.14 option but this will do only for our personal datasets

Unauthorized or production datasets will not be opened...

so we are using one tool to do string search... but this will not work at the background... the production pds contains approximately 5000 members, so we have to wait till the process goes

I am planning to run this in batch... I think the jcl for HRECALL which is given by saiprasad will cause a root to start my job

Thanks,
Ugandar

Hi Mark & Welcome to the forums & thanks for the reply

Got some queris to ask:
1.

1) In the parameter member used in HSM start up, although the patch can also be applied dynamically, in which case you won't be able to see it.

2) EX tells the system to EXECUTE the selected dataset.

3) The contents of the EXecuted dataset can be IDCAMS statements, HRECALL statements, or any other type of executable statement.
