Is there any option to verify size at destination end after NDM?
Hi,

I am using ndmcli to send files from one solaris server to another one.

I use the below one in script and verify the status.

Code:
select stat det=yes pnum="$PNUM"

Is there any option to automate in script in verifying destination size with source after doing NDM? Smilie

Well, NDM became Sterling Connect:Direct and is now IBM Connect:Direct. It is a very comprehensive file transfer system, and if it succeeds, the length and every byte are almost certainly all correct.

Determining the status of a transfer is more complex that with scp, and they provide many ways, of varing complexity, to determine this: ftp://public.dhe.ibm.com/software/co..._UserGuide.pdf

Yes, it may be accurate.

But we are sending files to external application. If suppose its delayed from normal time, they just wanted to confirm the size at our end.

Since its a manual process and number of files are quite high, we just wanted to automate the process.

Any thoughts?Smilie

If you bother to use, and pay for, Connect:Direct, you should trust it. What do you fear? This is not dumb old ftp/rcp. The file is probably transferred to a temp name until it is validated, probably with a polynomial checksum so they never get sued, so if it is present under the target name, it is good. I would not be surprised if the input file is either write locked or re-checksummed at the end, to ensure it was not modified during transmission! If you want to look at the remote file, you need another tool, as I do not expect it has ls like ftp/rsh/ssh, being very batch oriented and autonomous. There are probably warnings you can configure so if it fails to be successfully transferred by a certain time, you are notified. It is smart enough to recover from network and host glitches, but for a undetected outage it is not acceptable to wait and retry forever.

Currently we are using ndmcli. We can not change it to some other option.

Since external application asks us to confirm the file size, we can not tell them that you should trust the ndm. For safer side, we have to verify.

Since number of files are quite high, we would like to automate it.Smilie

What if you run md5sum on each file pair to verify they are the same? If so, there should be some way to automate that.

I am not sure what is md5sum.

Could you explain with an example?Smilie
