Communications Server

Network Administration Guide

Chapter 16. System Management Facilities

This chapter provides an overview of the Communications Server system management facilities and describes the capabilities that are common to each facility. Each facility also has some functions that are unique, and those functions are described for each facility.

The system management facilities enable you to monitor and control the communications resources of Communications Server. They also enable you to adjust these resources to improve the efficiency of SNA communication services or to monitor and test these services during problem determination.

Refer to Quick Beginnings for a list of resources that you can manage.

You can manage Communications Server with the following facilities:

You can use any combination of these facilities for Communications Server management.

Common Capabilities of System Management Facilities

Each system management facility can perform the following actions for resources:

You can perform a subset of these actions for each resource, as shown in Table 34.

SNA Node Operations

SNA Node Operations is an online facility for monitoring and controlling communications resources maintained by Communications Server. SNA Node Operations allows you to modify, delete, and monitor resources in your network.

You can use SNA Node Operations to help manage the resources in your network. The systems management programming capabilities of Communications Server enable you to configure and manage the nodes within your SNA network. SNA Node Operations provides a tree-view diagram of your configuration that enables you to select and modify resources in a hierarchical graphic interface.

You can manage multiple windows within the SNA Node Operations main window.

You can define more than one Communications Server configuration and switch between configurations as your needs require. When you start Communications Server, the default configuration is offered as the first choice for node configuration or node operation unless you specify another configuration. Once you have completed a new configuration, you can replace the default configuration with your new one. Use SNA Node Operations to apply your new configuration and ensure that the relevant part of the product runs as you have configured it.

SNA Node Operations enables you to launch other Communications Server programs, such as Log Viewer, Trace Facility, or SNA Node Configuration.

Remote Administration

SNA Node Operations can also be used to connect to a remote Communications Server and directly administer its resources. The user is able to remotely manage the resources for a Communications Server anywhere in the network.

A remote administration client installs only the administrative applications on a client, including SNA Node Operations. From this client, a user is able to fully administer any Communications Server in the network.

Windows 95, Windows 98, Windows NT, and Windows 2000 remote administration clients use Windows NT or Windows 2000 domain security to authenticate the client connection to the server without reentering the userid and password. The client must be part of a Windows NT domain, either by participation in a Communications Server domain or logging in locally with a synchronized userid and password.

Remote administration client users outside of the Windows NT domain are required to provide the userid and password, either through a prompt or by storing these values in the client configuration file.

The authorized users for remote administration clients are maintained in the IBMCSADMIN local group, which is located either directly on the Communications Server or on the domain controller where Communications Server participates. This user group is created during installation and can be administered using the Windows NT or Windows 2000 User Manager application. Remote administration client users must be given user rights in the IBMCSADMIN group to log on locally to the server.

Command Line Programs

Command line programs enable you to issue commands from a Windows NT or Windows 2000 prompt window. The output of commands is displayed on the screen, but the output can be redirected to a file.

Refer to Quick Beginnings for a list of command line programs you can use.

Web Administration

The Web Administration function of Communications Server is used to manage your server using a Web browser. This requires a Web server running on the same machine as Communications Server. The Web server, if installed prior to installing Communications Server, will be configured with the necessary virtual directories by the installation program. If you plan to use Web Administration, you should install the function when you install Communications Server by selecting "Web Administration" during the installation process. Refer to Appendix B of Quick Beginnings for information about security requirements for specific Web servers.

Most of the SNA Node Operations functions are available through a Web browser. You can query node status, start or stop the node, obtain information about resources, modify the resource state, display and edit configuration files, display the message log, and perform other administrative tasks.

SNA Node Operations ActiveX Control

There is an ActiveX control version of SNA Node Operations. This control allows you to imbed SNA Node Operations into any application that allows embedded controls such as the Microsoft Management Console (MMC). The name of the control is CSNTACTX and it is located in the product installation directory. This control has all of the SNA Node Operations functions and provides the benefit of embedding SNA Node Operations into other applications, enabling cross product management.

Tivoli Plus Module

If you use the Tivoli Management Environment (TME) to centrally manage the devices and applications in your network, the Communications Server Tivoli Plus module enables you to manage Communications Server from TME also. The Communications Server Tivoli Plus module can be installed on the TME server. A TME installable image is in the TME directory of the Communications Server CD-ROM. To access installed TME Plus functions, double click on the TivoliPlus icon that was added to the TME Desktop for Administrator panel. When you double click on the IBMCSNTPlus icon, you can use the icons in the panel to perform the following actions:

When you double click on any icon in the IBMCSNTPlus panel, enter information in the fields of the dialog box presented. Help is available for the fields in the dialog box.

APPN MIB Support

Communications Server supports simple network management protocol (SNMP) requests for APPN management information from any SNMP management system.

The SNMP Service is installed from the Services tab under the Network pulldown of the Windows NT control panel. After the SNMP Service software is installed on your computer, you must configure it with valid information for SNMP to operate.

You must be logged on as a member of the Administrator group for the local computer to configure SNMP.

The SNMP configuration information identifies communities and trap destinations.

S/390 Remote Operations Support (ROPS) for the NetView Program

When RUNCMD is issued from NetView, the value for the APPL parameter must be specified as APPL=CSRCMDS.

When the RUNCMD command is issued, all information, including the ID and password, is transmitted in the clear and is not secured in any way, unless the NetView suppression character is used when the RUNCMD command is issued. This information is displayed on the screen and entered in the NetView log. If passwords are transmitted to the ROPS service, the user is responsible for securing the NetView terminal and its NetView logs so that sensitive data is not compromised.
