Minor changes to “Operating System Messages”
Based on customer requirements, minor changes have been made to the “Operating System
Messages” screens:
The command line appears on the first page.
The Send and Receive push buttons have been removed.
There is now a check box for indicating that the command typed is a reply to a “Priority
Message”.
SNA Operations Management for Operations Automation
With the industry move to TCP/IP networks, Systems Network Architecture (SNA) Operations
Management commands will no longer be supported on z990 servers. These commands
were previously used by the System Automation for OS/390 product, as well as NetView®.
The recommendation is to now use the Simple Network Management Protocol (SNMP)
Application Programming Interfaces (APIs) for automation needs.
If the System Automation for OS/390 product is used, it must now be at Version 2.2 or
later. This will allow you to define an automation policy for SNMP APIs, rather than a policy
for SNA Operations Management commands.
If the SNA Operations Management commands on NetView are used directly, now an
SNMP agent and the SNMP APIs for systems automation management should be used.
For detailed information on the SNMP APIs commands and environment requirements, see
