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

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

This was a great information for me to know about.

Hi Ugandar,

The JCL to execute the HRECALL command in Batch

Code:
//RECALL EXEC PGM=IKJEFT01,DYNAMNBR=20,TIME=(9)
//SYSTSPRT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSUDUMP DD SYSOUT=*
//SYSTSIN DD *
HRECALL 'mention the dataset name's common part ' NOWAIT
/*


For e.g.
Code:
You want to recall these four datasets.
abc.aaa
abc.abd
abc.ddd
abc.ttt


then against SYSTSIN, you can mention
HRECALL 'abc.**'


Thanks
Sai

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

I tried to use 'EX' command at my site, got the follwoing messages:
Code:
ARC1020I DFSMSHSM IS RECALLING FROM DASD DSN=HLQ.EP.BBAL.TOEP600.C.G2621V.J
UN14, YOU MAY CONTINUE THE RECALL IN THE BACKGROUND AND FREE YOUR TSO SESSION BY PRESSING THE ATTENTION KEY

Pressed enter, next message shwon is:
Code:
A command entered or contained in a CLIST has invalid syntax.

Whilst when I used 'HR' command on some other migrated dataset, first message was:
Code:
ARC1007I  RECALL REQUEST 00110335 SENT TO DFSMSHSM
Pressed enter, message shown was:
Code:
ARC1000I HLQ.EP.EPD615.PGINV.SRT.F.NOV29.C128I  RECALL PROCESSING ENDED***


What should I conclude ! icon_confused.gif

P.S.: Above DSNs are of nature PS (QSAM).

From where you come to know about this? & I think 3.14 option is:
Code:
14 Search-For  Search data sets for strings of data          (Standard Dialog)
& used for search & not for recalling migrated datasets.

You need to have a proper access of production datasets before you recall them.

By the way, is there something known as abnormal mainframe ? icon_wink.gif

Hi Anuj - HSM appears to be set to run in the foreground at your site, which will wait until the dataset is recalled before processing the command against it, in this case EX (for EXECUTE).

Some sites will have a patch in the HSM parms (ARCCMDxx) to release control back to the user. This means you will get a similar message to above but you will be informed to try again when the dataset has been recalled.

By typing in EX the system will first process the HRECALL command, then the EX command.

The reason that you received the above message is that the second part of the process (the EXecute) is being carried out against the dataset recalled. EXecute can only generally be used with PS datasets or PDS members that contain CLIST or REXX code. I suspect that the dataset that you issued the EX against was probably JCL.

HR or HRECALL is a sub-command to HSM itself and purely instructs HSM to recall the dataset and doesn't process it any further.

To summarize -
to purely recall a dataset - use HR or HRECALL
to carry out additional actions against a dataset issue the relevant command: E, B, V, M, EX etc

Hope this helps.

Mark

Hi Mark & Welcome to the forums & thanks for the reply icon_smile.gif

Got some queris to ask:
1.
Quote:

From where can I know about this?

2.
Quote:

Ok, but what 'EX' tells the system to do?

3.
Quote:

Din't get this, why such a discrimination ?

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.

When I submit the job..it sends the RECALL results to TSO as messages.
How can it be directed to SYSOUT or a dataset. I want to implement this is a job that can be executed via CA7

Hello,

Why does someone believe a job needs to be scheduled to recall migrated data?

For the same reason that it is thought appropriate to revive a thread after three years?

I have a requirement where we are migrating from mainframes to another technology. But we still need to keep some datasets for 10 years for audit purpose. We need a batch process to touch these datasets every month to keep them from rolling off.

I thought of having IEFBR14 step with DISP=SHR. But we have limitations to this. IKJEFT01 will help us have the list of datasets in a PARM file. We can add or remove datasets from this list whenever we want it. IEFBR14 will require PROC changes ( have to go through installation procedures every time I want to add or remove the datasets)

Hello,

Why not simply back these datasets up to cart twice (prefereably "fat carts" - 3590) and hold them for the required amount of time.

If/when they are actually to be read, copy the needed data back to dasd and delete when done with the special request.
