zOS to zOS sfttp allocating output on lfile not rfile

Post by mklandrum »

Running the following job as first attempt using CoZ zOS to zOS. Using CERT authentication which is successful. Attempting to transfer a sequential file between LPAR's. Procedure opens the input lfile(MYDD) on source LPAR but then tries to open rfile(RMTDD) on same LPAR rather than target. Task fails with an open error. Obviously I'm doing something wrong. Running out of ideas, could use some help. Thanks

You can not reference a DD in the client job step from the remote server. If the remote server is CO:Z, you will have to references the dataset by dsname.

Is there a JCL example I can reference for transferring files between z/OS systems using a keyring. I've read the doc several times and just can't seem to get a successful run.

Please see:

https://dovetail.com/docs/sftp/client.html#client-batch

specifically, the second example JCL which uses a keyring CERT.
Also, Appendix F has more details.
