Figure 4-1: Single System Architecture

Manually Installing Cisco Info Center Components

This section describes the installation and configuration of components used to enhance the installed and configured multi or single system, or to install Cisco Info Center and manually configure the components.

Communication Protocol

Cisco Info Center uses client/server technology, therefore, all of the components can be installed either on one workstation or on separate workstations and platforms, communicating over a TCP/IP network.

Components installed on different workstations use the Cisco Info Center communications protocol to communicate with the Cisco Info Center software. This relationship is configured in the interfaces file.

Installation on Solaris 2.x Platform

This section describes how to install the Cisco Info Center system on a Solaris 2.x platform. The following assumptions are made:

the installer is logged in as root
the system is loaded with all of the components for the architecture of the target workstation
licensing will be installed
the CD-ROM drive is attached to the local system.

When the installer does not have root access (or at least write access to /opt), other users can run the Cisco Info Admin Desktop. (When only the Cisco Info Admin Desktop is being installed, root access is not necessary.)

The installation procedure covers the following steps:

1. Mount the CD-ROM.

2. Start the installation.

3. Select the target directory.

4. Select the components for the system.

5. Set the environment variables.

6. Install licensing.

Manual Installation - Mounting the CD-ROM

This section describes how to mount the CD-ROM on a Solaris 2.x platform.

Before you begin, you must have write access to /opt installation directory.

The CD-ROM should mount automatically when running the Solaris Volume daemon (vold) as /cdrom/infocenter. When this daemon is not running, mount the CD-ROM with the following command:

: host$ mount -o ro -F hsfs </dev/dsk/device> /cdrom

where </dev/dsk/device> is the CD-ROM drive device entry.

Manual Installation - Starting the Installation Program

When the CD-ROM is mounted, change directory to that location. For example, when the CD-ROM is mounted in the /cdrom/omnibus directory, specify the following command:

: host$ cd /cdrom/infocenter

To run the install program, specify:

: host$ ./oinstall

Manual Installation - Selecting the Target Directory

The installation program prompts you for the source directory. Press Return to select the default directory for the current platform. The default directory for Cisco Info Center is /opt/Omnibus.

To install in a different directory, specify another directory name.

When Cisco Info Center is not installed in the default directory, you must set the LD_LIBRARY_PATH environment variable so the dynamic loader can find the required shared library. See Section, "Manual Installation - Shared Libraries", for more information about this environment variable.

The install program now prompts for the required components.

Manual Installation - Selecting the Components for Your System

The installation program displays the available platforms. To the right is an installation status indicator. When the message SELECTED is displayed, all components for that platform are selected for installation. When PARTIAL is displayed, only some of the components for that platform are selected for installation. By default, no selections are made.

The Platform selection menu is displayed:

Cisco Info Center Version 1.0 Installation
 
Platform selection:

Option:

When any component on the platform is selected for installation, SELECTED is displayed to the right of the component.

To select a single component, specify the number displayed to the left of the component. You may repeat this process to select the components required for the installation.

When you want to select all components for the platform, specify option S (Select All). When you want to clear all the current selections, specify option U (Unselect All).

When you have selected the required components, specify option M to return to the Platform selection menu.

When you want to change the installation directory, specify option C in the Platform selection menu.

To display online Help, specify option H. To exit the install program, specify option Q.

When you have selected all the required components on all the required platforms, specify option I in the Platform selection menu to start the installation process.

Before the installation process continues, the selected platforms and components are displayed. When you want to change any of the platforms and components, specify N. Specify Y to confirm and the installation continues.

When you confirm the list, the install program checks that there is enough disk space available for the installation of the selected components. When the install program is unable to check the disk space, for example, with NFS mounted file systems or similar, it displays the message: "Unable to determine disk space. Do you want to try and install anyway?". Specify Y to install the required components without checking disk space.

When there is insufficient disk space, an error message is displayed along with the option to return to the Platform selection menu. When there is enough disk space, the installation starts.

At the end of the installation, depending upon the components picked in the component selection process, a Configuration menu is displayed.

Select option Q to quit the configuration process and proceed with the manual configuration as described below.

Manual Installation - Defining Environment Variables

Manual Installation - Set OMNIHOME

From this point on in the installation, the OMNIHOME environment variable must be set. This variable should point to the directory (/opt/Omnibus) in which you installed Cisco Info Center.

For C-shell users, specify the following command in the $HOME/.login file for each user:

: setenv OMNIHOME /opt/Omnibus

For Korn and Bourne shell users, specify the following command in the $HOME/.profile file for each user:

: OMNIHOME=/opt/Omnibus;export OMNIHOME

The PATH environment variable must be defined as follows:

: host% PATH=$PATH:$OMNIHOME/bin; export PATH

Manual Installation - Shared Libraries

The Cisco Info Center directory layout uses shared libraries, which contain rationalized common executables providing smaller executables and a smaller total distribution.

The run-time dynamic loader module automatically looks for shared libraries within the default /lib and /usr/lib directories. The libraries are installed in the default location specific to the platform. For example, the installation default location of the shared libraries for Solaris 2 is /opt/Omnibus/platform/solaris2/lib. When Cisco Info Center is started, the run-time dynamic loader searches this directory for the shared libraries, due to the default path being encoded within the header of the program.

When Cisco Info Center is not installed in the default directory, you must set a system environment variable in order for the dynamic loader to find the required shared library.

The environment variable is platform specific:

LD_LIBRARY_PATH on Solaris 2.x

For csh users, when you installed Cisco Info Center in the /opt/Apps/Omnibus directory, specify the following command:

: setenv LD_LIBRARY_PATH /opt/Apps/Omnibus/platform/solaris2/lib

For ksh and sh users, specify the following command:

: LD_LIBRARY_PATH=/opt/Apps/Omnibus/platform/solaris2/lib;
export LD_LIBRARY_PATH

Manual Installation - Licensing

You must set the NCO_ELMHOST environment variable to the host where the license daemon is located. For example, when the licenses are installed on the host muppet, using csh, specify:

: host$ setenv NCO_ELMHOST=@muppet

When you are using sh or ksh, specify the following command:

: host$ NCO_ELMHOST=muppet; export NCO_ELMHOST

This command ensures that components search for licenses on the host muppet before issuing a network broadcast. To search for licenses on multiple sources, prefix the host name with a @. For example, the following command (csh) ensures that components search for licenses on muppet, then on boomerang, before doing a network broadcast:

: host$ setenv NCO_ELMHOST=@muppet:boomerang:BROADCAST

When you are using sh or ksh, the command is as follows:

: host$ NCO_ELMHOST=@mupput:boomerang:BROADCAST; export NCO_ELMHOST

When you do not set the NCO_ELMHOST environment variable, components search for licenses by network broadcast only.

Manual Installation - Install License Keys

The Cisco Info Center system is licensed on a component basis. Before you can bring up the system, you must supply license keys, on the NCO_ELMHOST workstation. These licenses are installed in the Cisco Info Center license manager. To start the license manager, specify:

: host$ $OMNIHOME/install/nco_license

Accept all the default options and you are then supplied with a server code, which is generated from unique host information. Send the server code to support@MicroMuse.com (800-637-2665) to obtain your license keys.

When you receive your license keys, run the license manager again and specify the keys when prompted to do so, or press Return to skip a key. The nco_license command automatically starts the license daemon. To run it manually, specify the command:

: host$ $OMNIHOME/bin/nco_start_license

Manual Installation - Configuring the System

This section describes how to configure the Cisco Info Center system.

The configuration procedure covers the following steps:

1. Create the interfaces file for Cisco Info Center communications.

2. Run a Cisco Info Server using the nco_objserv command. For details, see Chapter 1, "Cisco Info Server" in the Cisco Info Center Administrator Reference guide.

3. Configure the system to run under process control. For details, see Chapter 2, "Process Control" in the Cisco Info Center Administrator Reference guide.

4. Define users and groups (for Cisco Info Center, not UNIX).

Interfaces File

For communications to be established between the components of Cisco Info Center, you must create an interfaces file.

The interfaces file contains information about:

which hosts run Cisco Info Server and how to connect to these hosts
which hosts run Info Gateways and how to connect to those hosts
entries for each host being managed by the Process Control system.

When Cisco Info Center components are started, they search for the $OMNIHOME/etc/interfaces.solaris2 file.

You can also use the nco_igen command's -java parameter to generate the interfaces file used specifically for Java support.

Without an appropriate interfaces file, the software looks for a file named $OMNIHOME/etc/interfaces and uses that as the interfaces file.

When that file does not exist, the programs are unable to contact any Cisco Info Servers and fail to run.

Figure 4-2: Server Editor Window

To create the interfaces file, use the Server Editor window, shown in Figure 4-2. To open the Server Editor window, specify:

: host$ $OMNIHOME/bin/nco_xigen

The Server Editor window may display an empty list or display the list of Cisco Info Servers, Info Gateways, or Process Control that may have been configured, along with the host name and the TCP port to which they are allocated. The list of servers is stored in the $OMNIHOME/etc/omni.dat file and any changes you make in the Server Editor window are saved in this file.

Note, although it is possible to edit the $OMNIHOME/etc/omni.dat file directly, it is recommended you use the Server Editor window to edit the list of servers. However, there may be occasions when you want to edit the connections data file. For more information about how to edit this file, see Section, "Editing the Connections Data File", in
Appendix B, in the Cisco Info Center Administrator Reference guide.

To change the host name:

1. Click on the server name to select it.

2. Specify the name of the host machine in the Host field.

3. Click on the Update button. The server is displayed in the list of servers.

4. Click on the Apply button. The interfaces file for the local platform is generated. A separate interfaces file for Java support is also generated automatically.

Add a Backup Server

Cisco Info Center allows you to specify back up hosts for each server defined. This ensures that when a server, for example, NCOMS, fails on the first host, Cisco Info Center attempts to connect to NCOMS on the backup host.

For example, to specify a backup host for NCOMS:

1. Click on the CISCO server in the main list.

2. Specify a different host name in the Host field.

3. Click on the Add button.

In Figure 4-3, the NCOMS server shows two backup hosts: muppet and darkstar.

Figure 4-3: Backup Servers in the Server Editor Window

Change the Priority of the Servers

To change the priority of the server in the list:

1. Click on the server name to select it.

2. Click on either the Raise or Lower buttons to move the server up or down the list, respectively.

Add a New Server

To add a new server to the interfaces file:

1. Specify the name of the server into the Name field.

2. Specify the name of the host machine in the Host field.

3. Specify the port number into the Port field.

4. Click on the Add button to add the new server.

5. Click on the Apply button to apply the changes.

Change the Server Details

To change a primary server:

1. Click on the server name to select it, or specify the server name in the Name field.

2. Edit the Name, Host, or Port fields, as required.

3. Click on the Update button.

4. Click on the Apply button to apply the changes.

Delete a Server

To delete a primary server:

1. Click on the server name to select it.

2. Click on the Remove button.

3. Click on the Apply button to apply the changes.

Test the Server

To test the server, click the Test button. A window is displayed providing the results of the test command.

Distributing Interfaces Information to Multiple Platforms

By default, the Server Editor window generates the interfaces file for use on Solaris 2.

: $OMNIHOME/etc/interfaces.solaris2

You can then copy this interfaces file to the $OMNIHOME/etc directory on each of the participating Cisco Info Center machines.

Starting the Cisco Info Center Components

This section describes how to install the startup scripts and configure the login procedure.

The Multisystem and Single System installation processes automatically add the automatic start-up procedures to the /etc/init.d/nco file.

To manually start the installed Cisco Info Center components, execute the following command:

: host$ /etc/init.d/nco start

To manually shut down the running Cisco Info Center components, execute the following command:

: host$ /etc/init.d/nco stop

Recommended Path Entries

Each Cisco Info Center user must have the OMNIHOME environment variable set and the $OMNIHOME/bin directory added to the PATH environment variable. For more information, see Section, "Manual Installation - Defining Environment Variables".

Default Event List Configuration

When you start the Event List, the default Event List configuration is displayed. The Event List displays one Monitor box.

You can, however, create a new Event List configuration and save it as default.elc. You should then copy this file to the /opt/Omnibus/desktop directory. (You must be logged in as root to write to this directory.)

Configuring the Login Window

The Login window is displayed when you start the Desktop tools. To modify the Server button on the Login window, use a skip filter file. This filter is an external file that comprises regular expression statements to define the servers that will not appear in the Login window.

To use this skip file, create a file called:

: $OMNIHOME/etc/skip-filter
