Need help on FTPing a dataset of huge length 1

[deveshjogal]

Hi

I have a requirement. I need to pull a dataset from UNIX box to OS/390. This dataset has only one records but the size of this record is about 4 megabytes. Is it possible to pull it using FTP or I have to go for some differnt approach.

As far my understanding I need to preallocate the dataset on OS/390. But I am not able to define a dataset with this huge length. Any help is appreciated.

Thanks

You do not have to pre-allocate, this works:

ip-name
user-id
password
cd /home/truus            
locsite lr=100 ref=fb tr pri=5 sec=5    
get        +                                   
hello.world +                           
'MVSHLQ.HELLO.WORLD.MVSLLQ'       
quit

In the locsite card you specify the parameters you would normaly specify in the DD card.

If you want to make the data a little bit smaller you can perhaps ZIP it. PKZIP is also available on the mainframe.

Hi

I tried the solution but it looks like the max reord length which I can define on OS/390 is 32K.

So it fails since my record size is > 32K.

Is it possible to break the single record in multiple records while pulling the file?

If you must do it while FTPing, then see if your local or remote FTP has the record description subcommand. If it does, specify the file as unstructured and set an arbitrary fixed record length.

When I have more time, I'll look up the exact syntax.

(The easiest way to handle this is to break up the record on Unix, then move it to IBM.)

You should be able to define it on the mainframe as 128 32k records. Or break it down by the fields in the record.

Hi

Dimandja

I tried to search on net. But not able to find a syntax. If you remember even a bit of the syntax post it. I will try to find the rest.

so far I am not in position to break the file before FTP. R u saying I can define a file with a record length of 12832K. If yes then how? Because it doesnt allow me to define a file with record length > 32k using. the FTP provided syntax or using the ISPF.


Thanks for ur suggestion.

Can you help me understand WHY you are trying to FTP this file to the mainframe and more importantly WHAT you expect to do with it once it gets there? Depending on the answer to these, it might be easier to provide you with a "solution".

IBM has a 32K limit on QSAM files - on DASD. They did (relatively recently) increase this for tape files - but I doubt that is what you want as your "target" file.

No, I meant 128 records, each 32k in length.
