IZUG1063E The SSH proxy command is not valid. Enter a valid SSH proxy command.

Explanation

When transferring files, z/OSMF adds the SSH proxy command to the SFTP jobs it generates, as follows: 

-oProxyCommand="proxy-command"
where proxy-command is a placeholder for the command you entered.
If the resulting JCL statement exceeds 80 characters, z/OSMF locates blanks within the proxy command and splits the command into multiple lines. For example, if you enter the following proxy command: 
ssh systemAB.xyz.1234.56789.abcdefg.pok.ibm.com exec /u/case/nc %h %p
z/OSMF uses the blanks to split the command into multiple lines and adds them to the SFTP jobs, as follows: 

-oProxyCommand="ssh systemAB.xyz.1234.56789.abcdefg.pok.ibm.com exec /u/case/nc 
%h %p"

This error is displayed if z/OSMF cannot create lines that contain 80 or fewer characters. It is also displayed if the SSH proxy command is missing or contains more than 500 characters.

System programmer response

No action is required.

User response

Enter a valid SSH proxy command, and ensure that z/OSMF can add the command to a JCL job and not exceed 80 characters per line. If necessary, add blanks to the proxy command so z/OSMF can break it into multiple lines in the JCL.
