how to search a dataset in all the volumes of storage using batch job,

as we do in 3.4 to list a dataset whether its present in the disk or not, similarly i need to do it in batch mode.

If you are familiar with ISPF services, LMDLIST can do what you need.

Sorry, you will have to write if by yourself...

hi Ofer,

Can you tell me how to get the listing of datasets in a flat file when we give some text like "test.dsds.*" in 3.4 of ispf.

Again, the LMDLIST service is the answer for you.

Hi ofer,

The link which you gave teaches how to do it using rexx, But i want it using only jcl.

why don't you give me the example jcl for it

enrico-sorichetti · Posted: Tue Sep 04, 2007 6:03 pm

Let' s straighten things up....

JCL itself does absolutely nothing, it is just a weird language to control/define the execution of "PROGRAMS"

Asking to do something with jcl has absolutely no meaning ...
trhu jcl You can invoke utilities, programs, and cause some side effects on datasets,
programs are the things which manipulate data.

One sample of such a task is to invoke IDCAMS to get a listing of catalogued datasets, or IEHLIST to get a listing of a disk VTOC.

Also...

asking on how to do something is a fair question, there are many ways of doing things,
asking on how to do something indicating the tool means that You have the skills to choose between different alternatives,
and You already used Your knowledge to choose the one which best suits Your needs.

It is just impossible to do what You ask for by using plain jcl.
You need to run/execute some kind of program ( an utility is just a program )...
it could be a system utility, some utility written by a third party
( fileaid for example -
I do not imply that fileaid might be used, it is just an example of a third party utility suite )

So please do not react strongly when somebody gives You a solution
which disagrees with Your expectations

Exploring The volume application of the ISMF main menu could be a good starting point
at least to get a volume list from where to proceed with further searches.

hi enrico-sorichetti,

As you have said that using IEHLIST we can retrieve the datasets, But i need only the dataset names which ever qualify the pattern which i give and nothing other than that.

not only listing on the screen i want to put it in a sequential file.

Can you give me the solution now.

enrico-sorichetti · Posted: Tue Sep 04, 2007 7:39 pm

if the datasets are cataloged, using the 3.4 and issuing a "save" command on the file list will save the dataset list into a sequiential file...

if the datasets are not cataloged, then You have to add to the 3.4 screen also the volume, and then same as before.

I do not have tso handy now but the ISMF dataset application will give You more freedom in selecting the dataset mask

Still if You want to run the process in batch Yo have to find some third party utility or write You own application

even better the DCOLLECT command will unload to a sequential file all the dataset info in one single shot, then with a simple application You can extract
all the info You need

the main point here is that if You want to collect info on uncataloged dataset, getting a list of the volumes might be a tedious task,
but if Your environment is full SMS then You should not have any uncataloged datasets, so the ISMF dataset application should give You whart You need

Hi enrico-sorichetti,

Press PF1 after SAVE to see the dataset name. More info can be found in the fine manual.

Hi all,

Thanks a lot for your valuable suggetions, Its working now.

But I couldn't make it using rexx code. I can give you what i wrote in my code

ofer71 · Posted: Wed Sep 05, 2007 3:13 pm

Have you read the fine manual carefully? There are some preceding services that need to be invoked prior to LMDLIST.

To see the actual ISPF messages, use SAY ZERRLM; SAY ZERRSM after the service call.

Hi ofer,

Its working fine now, I have changed the code

Also suggest looking at IGGCSIRX in SYS1.SAMPLIB, that would do it for you. But only for catalogued datasets.
