Hi,

Can anyone suggest if there is any way by which the recall of migrated datasets can be made faster by writing a code in REXX.
We usually type hrecall to do the same.

Regards,

Hi,
You can summit a batch job to recall all the datasets.
//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.
You want to recall these four datasets.
abc.aaa
abc.abd
abc.ddd
abc.ttt

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

just submit this jcl & then get rid of writing HRECALL against each & every dataset.

But when i m using a series of gdg's latest version,how to recall it?
like
....
HRECALL 'HLQ1.HLQ2..*.TEST(-1)' NOWAIT gives error when jcl is submitted..
the error is in writing (-1)..for the latest version,..

Hi

There is an another way that we can recall the migrated datset faster by simply giving 'HRECALL / NOWAIT XXXXX.XXXXX.XXXX' In the comment line.
After that you can check the Recall status by giving 'TSO HQ' .

I think that you need the absolute generation number when specifying a GDS.

Oooooooooops, hit submit a bit quick there ................

What do you mean by faster ? Can you make HSM work faster ?
NO, it goes as fast as it goes.

What version of HSM are you running
Do you have CRQ installed and working
Are you using RLS for the CDS

Hello,

How long does a recall take that you are concerned about making it faster?

Things in MIGRAT1 typically recall faster than MIGRAT2 (by design).

At most of my sites, a recall only takes a short while (unless the data will fill multiple dasd volumes :) ).

If you are watching/waiting the recall may appear to "take forever" - start the recall and then go for some water or whatever.
