Hi
I am trying to define a RRDS file through file aid with record length 18437. However it's giving error. I am able to define the same with record length 18000 though. Error code is return code 208. Please help.
Thanks

Well, you got something wrong and have given little to go on.

You should look up any messages you have been shown, and find out what they mean, and consider any suggestions for what to do.

Best guess, your bufferspace is too small.

You really should show the DEFINE CLUSTER statement. Not the data set name, volume / storage group or anything else that might be restricted, but the other parameters. You also should show the complete error message set, with restricted information redacted.

It's your business, but why such a large record length? It's my prejudice, of course, but I've always though data like this demands a relatively small record size. I will admit my prejudice in this was formed 30 or 40 years ago, and transfer rates and other DASD attributes are much faster now.

I've a feeling that particular record-length is almost the worst possible. 18432 is the closest CISIZE, which means a lot of wasted space per track.

Thank you everyone especially Bill. This was indeed a low bufferspace problem. I just changed the execution from online to batch, removed the bufferspace parameters from idcams and let system choose default, which resolved the issue.

Thanks again
Amit
