1.Review your TCP/IP profile data set for the NETACCESS statement definition and determine if the security zones are defined correctly. You can use the NETSTAT CONFIG (TSO) or netstat -x f (USS) command to display the current TCP/IP configuration, including the NETACCESS rules. Both of the commands in the example below display the current configuration for the TCP/IP stack named TCPIP2: (TSO) NETSTAT CONFIG TCP TCPIP2 (USS) netstat -f -p tcpip2 2.Issue the RACF RLIST command to display the list of users or groups that have access to the corresponding ...
