Removing a MVS file from CozBatch.

Post by chaky » Mon Sep 12, 2016 3:13 pm

Hi,

Currently we are placing a mainframe file on remote server. We want to make sure that as soon as the file is sent out, it is deleted. Is it possible?

Code: Select all

cd remotedir
pwd
ls -l
put //HLQLF.MIDQLF.LOWQLF.XXXXXX                 report.txt
Is it possible to delete the HLQLF.MIDQLF.LOWQLF.XXXXXX right after the put command?

Thank You.

OpenSSH sftp (on which co:z sftp is based) doesn't have a "lrm" subcommand.

Here are a couple of options:

1) have a following jobstep that deletes the dataset; make the step conditional on a zero CC from the Co:Z SFTP step
2) use the "!" subcommand in sftp to execute the tso shell command:

!tso delete "'HLQ.DSN'"

(unless a relative DSN, this requires a literal single quote enclosed in double quotes)

Unfortunately TSO DELETE didn't work as the way suggested in step 2.

and Step 1 I can't try, reason being is this. One of the SFTP failed with UNKNOWN reason. We can't determine what was the issue and Cozbatch didn't give RC 1 or 255. It completed with RC 0 with doing nothing. So I was thinking that whenever a successful connect happens and the file is sent, if I delete the file right away, I would be knowing that everything happened successfully.

Code: Select all

debug3: input_userauth_banner

Not enough information to tell what is going on.
You will have to attach your complete JCL and input script in order for someone to look at.

These errors:

lzopts: FSUM7351 not found
lzopts: FSUM7351 not found

are probably because the SSH connection failed but you have your subcommands in general STDIN vs a "here" document stdin to the cozsftp command.

I am passing below to STDIN

Code: Select all

cozsftp -F /export/home/prod/.ssh/ssh_config -vvv user_name@prod-server
lzopts mode=text,loglevel=I
lzopts -a
cd serverdircet
cd folder
pwd
put //HLQLF.MIDQLF.LOWQLF.XXXXXX                 report.txt
ls -l
pwd
And below is the output in STDOUT. If we see that connection gets closed by UNKNOWN and Yes, I agree that "FSUM7351 not found" would have come when the connection failed.

You need to use a << "here document" to properly input the subcommands into cozsftp command.

See the sample JCL:

SFTPSAMP (preferred)
RUNSFTP (old version)

I am sorry, I may be asking a very dumb question. But where I can see these sample JCLs you are taking about?

The Co:Z SAMPJCL dataset is part of the installation.
