I have tried creating the alias name for a dataset by using
"DEFINE ALIAS( NAME("aliasds") RELATE ('"realds')" . It works fine. But I am not able to view the aliasds using 3.4. Is this possible? can u provide me sample algorithm to create and view the alias name for a dataset.

Thanks,
Sailaja

sailaja,

Alias can be created using IDCAMS - DEFINE ALIAS. You can open the ALIAS in 3.4 and the dataset mentioned in RELATE would be opened.

Let me know if i have misunderstood your question.

It has worked OK for me in the past. ANd have just tested again, and it works perfectly.

Please post your code qand output.

Hi,
address TSO
aliasds = 'cfb1.srcedat1'
"DEFINE ALIAS( NAME("aliasds") RELATE('"NUNAS66.PRIME.QBBBF.SOURCE.DATA"'))"
exit

This creates the alias ds as 'NUNAS66.cfb1.srcedat1'. It is appending my UserID as the high qual for the dataset. I was also able to view the ds 'NUNAS66.cfb1.srcedat1'. But my intention is to create the dataset without that higher qual. So i ran the rexx by insrting the quotes for the aliasds variable as such
"DEFINE ALIAS( NAME('"aliasds"') RELATE('"NUNAS66.PRIME.QBBBF.SOURCE.DATA"'))" . Now it is saying that the alias is created but when I am trying to virw the cfb1.srcedat1 in 3.4 , it is saying that the 'Dataset Not Cataloged'.

So could me please assist me in solving the issue.

Thanks & regards,
Sailaja

Have you tried running with TRACE I to see exactly what is happeneing.

My code works perfectly.

I noticed that the alias files are created as VSAM files for the datasets having the higher qual as 'CFB1' eventhough the base dataset is a non VSAM ds. So I was not bale to view them at my env. Is there any other alternative way by which I can create alias datasets as non VSAM files.

My alias shows up as Code:
xx.JCL.SECOND *ALIAS
when I use 3.4

You can define an alias via IDCAMS in batch.

TSO HELP DEFALIAS indicates the syntax is ALIAS(NAME('name') and from what you've posted it's hard to tell if you've used single quotes or double quotes in your command. If double quotes were used, that would explain the user id prefix -- normally TSO will prefix a dataset name with your user id UNLESS you use single quotes around the name.

And depending on how your site is set up, you may be required to use a user catalog with the CATALOG option of the DEFINE ALIAS. If not used when needed, the alias may be defined in the wrong catalog and access attempts could fail when the high level qualifier's catalog is searched and the dataset not found.
