Does NetMaster require the VTAM start option OSIMGMT=YES?

Products

• NetMaster Network Management for TCP/IP
• NetMaster Network Management for SNA

Issue/Introduction

We will be upgrading from z/OS 2.4 to zOS 2.5.

The IBM Planning doc for upgrading to z/OS 2.5 states that because the VTAM topology agent and the  VTAM Common Management Information Protocol (CMIP) services on z/OS will no longer be supported after z/OS V2R4, an alternate method of obtaining SNA topology data must be used. IBM recommends using the SNA network monitoring network management interface (NMI) to monitor SNA Enterprise Extender and High  Performance Routing data. 

 

Environment

Netmaster for TCP/IP Release : 12.2

Resolution

NetMaster never used the OSIMGMT option and thus there's no need for that parm.  

NetMaster SNA Automation has always done its discovery via a multitude of VTAM display commands.

Netmaster already uses the IBM NMI interface for EE/HPR data, so that is also not a concern.  
The IBM NMI was available in 12.1 with PTFs, and in 12.2 as the default. 

Additional Information

To verify whether the IBM NMI is active, check the SOLVESSI STC output for this message.
