Return 102 - todsnÝE¨: CoZClient: Error: no exit code received from CoZServer

Post by zond2tmx » Thu Dec 17, 2015 4:48 pm

I am testing a Launcher/Dataset Pipes job that transmits a data set from one z/OS LPAR to another z/OS LPAR. Both LPARs are on the same physical machine. Depending on what changes I make the jobs ends with either a RC=102 or RC=103. The most recent series of tests have completed with 102. I've reached a point where I do not know what else to try. Can you help?

Here is the JCL:
//STEP0010 EXEC COZLNCH,ARGS='-LT,t PKSCM0@SYSC.DEVL.COM'
//STDOUT DD SYSOUT=*
//STDERR DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//COZCFG DD *
ssh-options=-oStrictHostKeyChecking=no
server-env-PASSWD_DSN=//PKSCM0.USS.CNTL($PW)
server-env-SSH_ASKPASS=/usr/local/bin/coz/bin/read_passwd_dsn.sh
server-env-DISPLAY=none
//STDIN DD *
fromdsn -l rdw //PKSCM0.TEST.SYSC.DATA |
todsn -ssh PKSCM0@SYSD.TEST.COM -l rdw //PKSCM0.TEST.FROM.SYSC

Re: Return 102 - todsnÝE¨: CoZClient: Error: no exit code received from CoZServer

The causative errors are these:

FSUM6764 logname: cannot get login name
- this probably means that your z/OS userid isn't setup properly to use z/OS Unix System services

EZYXW11E XtlibError: invalidDisplay xtInitialize XtToolkitError
Can't open display: 172.24.30.28:0.0
- your current z/OS OpenSSH client ssh options seem to be trying to forward an X display.

FOTS1346 Permission denied, please try again.
- This error is from z/OS OpenSSH, meaning that it cannot authentication with the target SSH server.

Here's my suggestion for how to debug this.

1) Log into a z/OS Unix shell using an SSH client (like PuTTY). Use the same z/OS userid that you are running this batch job from and log into the same LPAR.

2) from the z/OS Unix shell:
ssh -vvv PKSCM0@SYSC.DEVL.COM

capture the output, scrub any sensitive stuff from it and post it and we will review.

I’ve made some progress though I still cannot get the file to copy. I have been able to eliminate the following errors:
FSUM6764 logname: cannot get login name
EZYXW11E XtlibError: invalidDisplay xtInitialize XtToolkitError
Can't open display: 172.24.30.28:0.0
FOTS1346 Permission denied, please try again

I was able to eliminate the FSUM6764 message by removing the following from my .profile:
export USERID=$(logname)

The rest of the messages disappeared when I reversed the transmission. That is, instead of running the job on SYSC and ssh’ing to SYSD, I ran the job on SYSD and ssh’d to SYSC. I had forgotten that SYSC was not setup to ssh into SYSD.

As you requested I ran an ssh command with the –vvv option from the z/OS Unix shell. I logged onto SYSD and executed ssh -vvv pkscm0@sysc.ameritas.com. The output is as follows:

Re: Return 102 - todsnÝE¨: CoZClient: Error: no exit code received from CoZServer

Post by dovetail » Tue Dec 22, 2015 9:24 am

OK, so it looks like the SSH connection is working now.

BTW: if you just want to do something as simple as copy a file, you might just use Co:Z SFTP. Co:Z Launcher is intended for distributed processing, which can include file exchange.

Otherwise, try running your Co:Z Launcher job again, but with these tracing options:

//STEP1 EXEC PROC=COZPROC,
// ARGS='-LT,t myuid@linux1.myco.com'
//COZCFG DD *
server-env-COZ_LOG=T,t
agent-options=-LT,t
target-env-COZ_LOG=T,t
//STDIN DD *
set -x
# the rest of your shell script...
//

This will trace all of the components. Run a minimal test job that has these options and then download the entire job log and either attach it of if you prefer email it to info@dovetail.com and we will take a look.

I sent the output in an e/mail since it was large.

I'm not sure I understand what you are trying to do.

What do you have in your //STDIN DD; Is it this? -

//STDIN DD *
set -x
fromdsn -l rdw //PKSCM0.TEST.SYSD.DATA
todsn -ssh PKSCM0@SYSC.DEVL.COM -l rdw //PKSCM0.TEST.FROM.SYSD
//

If so, I don't think that this does what you intended: you probably don't want to start another ssh session from the target system.
If you are trying to read a dataset from the originating z/OS system and write it to the target z/OS system, you probably want this:

Code: Select all

//STDIN DD *
set -x
fromdsn -l rdw //PKSCM0.TEST.SYSD.DATA  |
todsn -local -l rdw //PKSCM0.TEST.FROM.SYSD
//
Also, you probably don't want to use Co:Z Launcher to just do a file transfer; normally it is used when you want to run a remote program and exchange data at the same time.

If you just wanted to do file transfer with Co:Z SFTP on both sides, you could do the above with:

Code: Select all

//SFTPPUT EXEC PROC=SFTPPROC 
//SFTPIN DD * 
pwdsn="COZUSER.COZ.SAMPJCL(PW)" 
user=myuser
host=myhost 
                                                           
. $script_dir/sftp_connect.sh <<EOB
# source z/OS settings:
lzopts mode=binary,linerule=rdw
# target z/OS settings:
zopts mode=binary,linerule=rdw
zopts recfm=vb,lrecl=222,space=cyl.3.3
put //hlq.source.dsn //hlq.target.dsn
EOB
//

I think I have been suffering from a gross misunderstanding as to the purpose of Data Set Pipes. You mentioned that what I am attempting to do is better suited for Co:Z SFTP. This is certainly the case as I got that working with no issues.

I did get launcher to work when I used the parameters you outlined. i.e. fromdsn -l rdw //PKSCM0.TEST.SYSD.DATA |
todsn -local -l rdw //PKSCM0.TEST.FROM.SYSD

Nevertheless I am going to use Co:Z SFTP.

Thanks for your help.

The "Dataset Pipes" frameworks are included in Co:Z SFTP. In other words, they share the same code base for being able to "stream" data sets with lots of options.

Here's a component overview:
http://dovetail.com/solutions.html

Co:Z SFTP is just file transfer that is compatible with the SSH2/SFTP RFCs.
See: http://dovetail.com/products/sftp.html

Co:Z Launcher / Dataset Pipes (aka "Hybrid batch) is an environment for running distributed work from z/OS while exchanging data.
For a little overview video, see:

"Introduction to z/OS Hybrid Batch Processing"
