z/OS UNIX REXEC trace example and explanation

The z/OS UNIX REXEC can be invoked using either rexec or orexec. Enter one of the following commands with either an IP address or a host name.

IPv4

    orexec -d -l debfox -p mypwd -s 1512 197.22.190.1 ls -al

IPv6

    orexec -d -l debfox -p mypwd -s 1512 fec0:0:0:12BE::1 ls -al

The following are examples of the trace output:

IPv4

EZYRC02I Host: 197.22.190.1, user debfox, cmd ls -al, port 1512

IPv6

EZYRC02I Host: fec0:0:0:12BE::1, user debfox, cmd ls -al, port 1512

     EZYRC01I  Calling function rexec_af with the following:
     EZYRC02I  Host: fec0:0:0:12BE::1, user debfox, cmd ls -al, port 1512
     EZYRC19I Data socket = 4, Control socket = 6.

EZYRC01I shows that the z/OS UNIX REXEC function has been called in the runtime libraries. EZYRC02I shows the parameters that have been passed to the REXEC() function in the runtime library. EZYRC191 shows the socket descriptor being used for the data connection and the control (or standard error) connection.
