Preparing to Install NerveCenter on UNIX

Before you install NerveCenter, you must set up the environment by backing up existing NerveCenter files, stopping processes, creating users and groups, and configuring services.

Note You cannot install multiple versions of NerveCenter on the same machine. Only one version can be installed on a machine.

Before you prepare the machine, make sure you meet the prerequisites in the following table:

Prerequisites for Installing NerveCenter on UNIX

If you are installing...	You must...
Over an existing 3.5 or 3.6 version of NerveCenter	See Upgrading to NerveCenter 3.7 for more information about upgrading from version 3.5 and later to version v3.7.
Any NerveCenter component	The computers where you'll install NerveCenter must meet the system requirements for your environment, as described in the Release Notes. Have X-Windows software with Motif or CDE to run the following NerveCenter components: Server, Client, Administrator, ipsweep, serializedb, importutil, and nccmd. For the utilities (ipsweep, serializedb, and importutil), an X server does not have to be running, but the DISPLAY variable must point to a valid X display. Have root privileges to run the installation script.
The OpenView Platform Adapter	Install and start the HP trap service (ovtrapd). Have HP OpenView running on this machine. If HP OpenView is running on a Windows system, you will need to install the OpenView Platform Adapter on that system. PlatformPath and PlatformBinPath refer to the fully qualified path names of the network management platform installation directory and the directory containing all the platform executables, respectively (for example, `/opt/OV` and `/opt/OV/bin`).
The Universal Platform Adapter	Have either Micromuse Netcool/Omnibus (including the NerveCenter probe) or Tivoli TME 10 installed on this machine. Note You must get the NerveCenter probe, which is a Micromuse product, from Micromuse.
Web server	If you are installing Web support, you don't have to install any NerveCenter components on the Web server itself. However, you do need to be familiar with the Web server, its location, and its configuration files.
CD-ROM drive	Make sure that the workstation that will be the OPEN NerveCenter Client or Server host is the same type of workstation as the one connected to the CD-ROM drive you'll use during installation. For example, if you're installing OPEN NerveCenter on an HP workstation, make sure the CD-ROM drive is attached to an HP workstation.

To set up your machine:

On the system where you plan to install OPEN NerveCenter, log in as root.
If NerveCenter is already installed on this machine, stop all NerveCenter and Wind/U processes. See Upgrading to NerveCenter 3.7.

If any of these processes are still running when you start the installation script, the script will quit and display a list of the processes you must stop. Once you have stopped the processes, you can rerun the script.

If NerveCenter is already installed on this machine, back up any files that you have customized for your business or your environment. See Upgrading to NerveCenter 3.7.

During the installation, if the install script detects existing copies of nervectr.mib, mibcomp.txt, ncexport.asc, or nervecenter.ncdb, the install script will not overwrite them. It will install 3.6 versions of these files (filename36.ext) for you to use later if you want to.

If you want to remove the NerveCenter application before installing the new version, do so now. See Removing OPEN NerveCenter or Upgrading to NerveCenter 3.7.
If the following two groups don't already exist, create them: ncadmins and ncusers.

Caution Do not create these groups on the NIS client machine. If you do, you will not be able to log in to the NerveCenter Server on that machine.

Create a new user, nervectr, that is a member of ncadmins.

Note Create the nervectr user in the NIS database if the machine running the NerveCenter Server is using NIS for user authentication.

If you are installing NerveCenter on HP-UX, make sure that HP Services is configured to search both /etc/services and NIS by doing the following:

a. Run sam and choose Network and Communications.

b. Then choose Name Service Switch.

c. Make sure the services line includes entries for NIS and /etc/services.

d. Select the services line.

e. Then, use the right mouse button to select Configure Name Service Switch.

f. In the window displayed, set If Information is Not Found to Try Next Source.

If you are installing NerveCenter on HP-UX, make sure the kernel parameter, nfile, is set to at least 1000 to allow more open files:

. Run sam and choose Kernel configuration.

a. Then choose Configuration parameters.

b. Set nfile to at least 1000.

If you are installing NerveCenter on HP-UX, make sure the kernel parameter, maxfiles, is set to at least 200:

. Run sam and choose Kernel configuration.

a. Then choose Configuration parameters.

b. Set maxfiles to at least 200.

Once you have finished configuring the system, you can install NerveCenter.
