Hi,
I am to take the bkup of a PDS in to another PDS,for this i am using following JCL:

After execution,when we try to open the o/p, it says "invalid record format".
Please advice.
The attributes of i/p pds is as follows:
General Data Current Allocation
Allocated tracks . : 12
Allocated extents . : 1
Maximum dir. blocks : 50


Organization . . . : PO Current Utilization
Record format . . . : FB Used tracks . . . . : 12
Record length . . . : 80 Used extents . . . : 1
Block size . . . . : 27920 Used dir. blocks . : 12
1st extent tracks . : 12 Number of members . : 68
Secondary tracks . : 10
Data set name type : PDS

If MYDD2 is supposed to be a PDS, then you failed to provide a value in the SPACE parameter for the directory blocks. It should look something like this:



SPACE Syntax.

If your input is 12 tracks then 30 cylinders seems like overkill!

Thanks MrSpock ,
Its working now !!!

I have that same situation. I did not define directory blocks either but thought that either they would be provided by SMS or take the attributes of the file that was being copied? Is this a wrong assumption?

Hello,

How would SMS know before the process begins that the output is to be a pds?

Not all utilities automatically copy the input dcb info when it is not wpecified in the output definition.

I would assume it would inherit the attributes of the infile. When you copy a dataset in ISPF, it will ask you if you want to carry over the attributes. Of course, I'm new to this and it may be a falicious assumption.

Hello,

When you copy a dataset in ISPF, it will ask you if you want to carry over the attributes.

Yes, it will. As long as you are using ispf/copy. Some batch utilities also copy dcb info unless told otherwise.

Of course, I'm new to this and it may be a falicious assumption.

Yes, it is. . . Unfortunately, things work as they work - not necessarily as something else works. . .
