If message
IPNS0809 UNIX shell initialization failed, CALL=760 RC=129 RSN=0594-003D
appears in response to any NETSTAT command. This is caused by the OMVS segment of the SSI started task user ID having not the correct definitions for Parameters HOME= and PROGRAM= in the security definition of the OMVS-Segment. Most likely they are not written in lower case and therefore do not match the directory names in OMVS. After having changed that the message IPNS0809 does not appear.
