Logging In After Upgrading

If the Login Manager dialog box on the CiscoWorks2000 desktop does not appear correctly when you try to log in for the first time after upgrading, clear your browser cache as follows, then reenter the server URL in your browser.

Note Wait for a few seconds after the server starts before logging in. If you have trouble logging in, use the Reload button on your browser.

For Microsoft Internet Explorer:

Step 1 Select View > Internet Options. The Internet Options dialog box appears.

Step 2 Select the General tab.

Step 3 Click Delete Files.

For Netscape Navigator:

Step 1 Select Edit > Preferences. The Preferences dialog box appears.

Step 2 Select Advanced > Cache.

Step 3 Click Clear Memory Cache, then click OK in the Memory Cache dialog box.

Step 4 Click Clear Disk Cache, then click OK in the Disk Cache dialog box.

Understanding Installation Messages

The messages that might appear during installation are:

•Information messages, which give you important details

•Warning messages, which tell you that something might be wrong with a particular process, but the process will complete

•Error messages, which tell you that a particular process could not complete

All messages that appear during installation are logged in the /var/tmp/ciscoinstall.log file.

Table A-1 shows messages that might occur during installation and describes their reasons.

User `bin' appears in `/var/adm/cron/at.deny'. Software Image Manager requires `bin' to be able to run `at'. Contact your local technical support representative to edit the file /var/adm/cron/at.deny and remove the entry for bin.

User `bin' appears in `/var/adm/cron/cron.deny'. Software Image Manager requires `bin' to be able to run `crontab'. Contact your local technical support representative to edit the file /var/adm/cron/cron.deny and remove the entry for bin.

Wrong OS.

Operating system is not HP-UX or not a supported version of HP-UX.

Make sure that you are running HP-UX 11.0.


Installing Syslog Analysis

If the Essentials installation fails during Syslog Analysis installation, make sure you do not have the Cisco DNS/DHCP Manager (CDDM) installed on the same machine as Essentials. CDDM, which can be downloaded from CCO, provides syslog and TFTP daemons as part of its product. You cannot run CDDM Syslog or TFTP on the same machine as Essentials because they are not compatible. Make sure the server on which you install Essentials is not running CDDM Syslog or TFTP. The following message is displayed: 

WARNING: The tftp directory `/usr/tftpdir' appears to be NFS mounted.

Using NFS directories often increases the software transfer time and 
may cause a failure during distribution of the software to the device.

Contact your local technical support representative to make 
`/usr/tftpdir' a local directory.

Failure to Delete a Package During Uninstallation

If you try to remove Essentials but the uninstallation program fails to delete a package, try running the uninstall program again. Several circumstances can cause a package to remain after uninstallation. Usually, running the uninstall program again removes the package.

Accessing the CiscoWorks2000 Server

The CiscoWorks2000 Server uses port 80 by default. This port is normally used by web servers. If you receive an error message that an existing web server is already configured to run on port 80, and the alternative port 1741 is used instead, verify that you entered the correct URL for the server: 

http://server_name:1741

where server_name is the name of the machine where CiscoWorks2000 was installed, and 1741 is the alternative port on which CiscoWorks2000 is installed if port 80 is in use.

Verify the Server Is Running

To make sure your server is running, enter: 

ping server_name

Proxy Server Problems

If you get a message that the server is "alive," and get a proxy error when you try to connect to the server, make sure the proxy is set up correctly. If your server is configured to use a proxy server outside the firewall (specified in Netscape Navigator under Options > Network Preferences > Proxies), you will get proxy errors if you configured the proxy to ignore requests to a certain machine, set of machines, or domain.

Your proxy is set up incorrectly if:

•You receive an error message that you are using a proxy outside the firewall.

•The proxy server recognizes www-int as an internal server, so it does not proxy requests to that server.

•You set up a new internal server, www-nms, but when you make a request to the proxy server, it does not recognize www-nms as an internal server and proxies the request.

•The proxy server outside the firewall tries to request data from a server inside the firewall, and the request is blocked.

•You get a "Connection Refused" error from the proxy server.

Daemon Manager Not Running

If the Daemon Manager is not running, CiscoWorks2000 cannot run. When you install or uninstall CiscoWorks2000, the Daemon Manager is temporarily stopped and then restarted. If the install or uninstall process is interrupted, the Daemon Manager might remain in the stopped state.

Note Wait a few seconds after the server starts before logging in. If you have trouble logging in, use the Reload button on your browser.

To start or stop the Daemon Manager:

Step 1 Log in as root.

Step 2 Open a shell window.

Step 3 Start the server by entering: 

# /sbin/init.d/dmgtd start

Step 4 Stop the server by entering: 

# /sbin/init.d/dmgtd stop

Viewing Process Status

You can check back-end server process failures by selecting Server Configuration > Administration > Process Management > Process Status. Only users with administrator privileges can start and stop processes. For details, refer to Getting Started with the CiscoWorks2000 Server.

Browser Problems

If the desktop buttons do not work, Java and JavaScript are not enabled. Make sure you enable Java and JavaScript.

Make sure the browser cache is not set to zero.

Do not resize the browser window while the desktop main page is loading. This can cause a Java error.

For more information about setting up browsers, refer to Installing and Setting Up CD One on HP-UX.

Improving Server Performance

To improve system performance for Essentials:

•Reduce the number of managed devices polled by Availability.

•Increase the interval used by Availability to poll managed devices.

•Reduce the number of syslog messages saved to the CiscoWorks2000 database.

•Increase the interval used by Configuration Management to collect information about managed devices.
