The CiscoWorks Blue mainframe application acts solely as a server to provide Systems Network Architecture (SNA) resource information to the CiscoWorks Blue Maps and SNA View applications on workstations. There are no end-user functions provided. For information about how the SNA information is used at the workstation, see the CiscoWorks Blue Maps and SNA View Workstation Installation and Administration Guide or the CiscoWorks Blue Maps and SNA View User Guide.
The mainframe component provides the SNA PU and LU information to the workstation program. It runs as a started task under OS/390 (MVS/Enterprise Systems Architecture).
The workstation component obtains the PU and LU information from the mainframe and stores it in a database at the workstation.
Note PUs connected using the remote source route bridging (RSRB) protocol and a CIP or 3172 connection to the mainframe will not benefit from the correlation feature. This means that the Maps and SNA View applications will not be able to determine which routers these PUs are dependent on for connectivity to the mainframe.
The workstation program provides the user with PU and LU information. To provide these services to the workstation user, the mainframe application uses the interfaces described in the following sections.
When you install the mainframe application, you get a fully functional Virtual Telecommunications Access Method (VTAM) exchange identification (XID) configuration services exit routine. For more information, read the section "Updating MVS and VTAM"in the "Updating the Mainframe Application Software" chapter.
The mainframe application provides a set of mainframe commands with which you configure and monitor the mainframe environment. You can start, stop, and display status for the mainframe subtasks. For more information, read the section "Issuing Mainframe Commands"in the "Using the Mainframe Application" chapter.
The mainframe application includes a series of subtasks that run on the mainframe. These subtasks provide connections to the workstations and PU/LU discovery and monitoring. For more information, read the section "Mainframe Subtasks"in the "Using the Mainframe Application" chapter.
This section lists the major changes for CiscoWorks Blue Maps and SNA View 2.0.
The features of the Maps 1.2 and SNA View 1. 2 applications are combined into one application called CiscoWorks Blue Maps 2.0. The SNA host functions are incorporated into the Maps application and the old SNA View task manager is gone.
The CiscoWorks Blue Maps 2.0 applications include the original DLSw, APPN, and RSRB Motif and web-based applications and the following new applications:
The Administration application lets you discover the network, add, delete, and modify devices in the database, and select DLSw key devices using a Motif interface independent of the protocol maps.
The Process Manager application starts and stops all Maps and SNA View processes.
The Message Log Viewer displays messages generated by the Maps and SNA View processes.
A new, separately licensed program, CiscoWorks Blue SNA View 2.0 provides a web-based method for displaying session lists and session paths for all SNA PUs and LUs, including traditional subarea SNA, DLSw, RSRB, APPN, APPN/DLUR with DLSw, and TN3270. The CiscoWorks Blue SNA View release 2.0 application uses the same discovery and polling processes and SNA host connection to keep the common database current, whether you are running Maps, SNA View, or both.
A new cwb command interface lets you start and stop processes, servers, and user interfaces.
You can now install and use CiscoWorks Blue Maps and SNA View without CiscoWorks, CiscoWorks 2000, or a Network Management System.
The CiscoWorks Blue 2.0 applications now use the SQL Anywhere database.
CiscoWorks Blue SNA View will integrate with the Device Center component of CiscoWorks 2000, if installed on the system.
CiscoWorks Blue SNA View will integrate with the UNIX-based version of CiscoView, if installed on the system.
Some Maps 1.2 interfaces are no longer applicable in release 2.0. Table 1-1 shows you how the interfaces from release 1.2 are used in release 2.0:
The Maps and SNA View applications no longer provide their own operator interface to the mainframe. The message and command clients no longer exist. Instead, you can use the NetView operator console or the NetView for OS/390 or SOLVE:NetMaster web pages.
A new command, cwb tac, collects and compresses the files and database information when you need to call Cisco TAC for service.
A new command, cwb verify, checks that you have completely installed the product, completed the configuration files, and started the appropriate servers and processes before your users start their applications.
The APPN Poller process has been removed. APPN polling is now done by the cwbsnamapsd daemon and the AppnPollerServer.
The cwbsyncd, cwbdlswdiscoverd, and cwbrsrbdiscoverd daemons are removed. To implement automatic discovery, use the cwb start command to start the discover processes as a UNIX cron job in the cron table (crontab).
