Troubleshooting Tips

System Requirements for Browsing to a Device

The system requirements for the Management Agents for OpenVMS are the following:
  • A supported web browser

Browser Recommendations

  • Microsoft Internet Explorer 4.01 or above

    NOTE:Internet Explorer 4.01 requires service pack 3 on Windows NT 4.0.
  • Netscape Navigator 4.50 or above

    NOTE:Netscape Navigator also requires the Java Development Kit (JDK) 1.1 patch available at:     http://help.netscape.com/filelib.html?#smartupdate.

    To update Netscape Navigator on line with the JDK 1.1 patch:

    1. Run Netscape Navigator and go to the above URL.
    2. Click on the JDK Update button.

    • Additional browsers, or the browsers mentioned, used with different operating systems, might or might not work correctly, depending upon their specific implementations of the required browser technologies.

Browser Requirements

The browser must have the following features supported and enabled:
  • HTML tables
  • HTML frames
  • JavaScript
  • Accept all cookies
  • Full Java Development Kit 1.1 (JDK 1.1) support
  • Dynamic HTML

Known Browser Issues

  • If you are unable to access a machine that has web-enabled agents installed with a URL such as http://127.0.0.1:2301/, or or http://125.12.18.36:2301/, try adding the address to the No Proxy list in the browser.
  • Internet Explorer does not print background colors and images by default.
  • When switching from a web agent browser window to another application, you may see the colors in the browser window change/flash. This is not specific to the web agent window but may happen when looking at other pages with a browser under the same conditions.
  • When the browser window is resized with Netscape Communicator 4.03, the window or frames within the window may go blank. This is due to the JavaScript in the page not being evaluated. To view the page, right-click in the frame, and select Reload Frame.
  • Frame sizes are optimized for "medium" fonts. If you switch your browser to use larger or smaller fonts, you must manually adjust the frame layout using the mouse.
  • A JavaScript error can occur when resizing the browser window in Netscape Navigator.
  • A JavaScript error can occur when trying to print certain pages in Netscape Navigator.

Troubleshooting Questions and Answers

Q: One of my subagents (MIBs) is not running.
A: Define a foreign command, and use trace to give an indication of failure. For example:

    $ SCSI   :== $SYS$SPECIFIC:[WBEM.AGENTS]CPQSCSI_MIB.EXE    $ SCSI -TRACE

If this does not assist you in debugging the subagent, save the output of these commands and mail it to us. (The address is at the end of this section.)

Q: I was able to see the Device Home page, but there are no links for agents on the page. Why?
A: This occurs if JavaScript is not supported or enabled. If you are using a recommended browser, ensure that JavaScript is enabled.

Q: When I try to log in, I get a Java error and I am not prompted for Account and Password. Why?
A: This will occur if the browser does not fully support JDK 1.1 Java applets or if Java support has been disabled. Ensure that Java support is enabled in the browser. If not, upgrade to a browser that fully supports JDK 1.1 Java applets. If you are using Netscape Navigator, update the browser with the JDK 1.1 patch as shown under Browser Recommendations above.

Q: Is there an easier way to access the local device with my browser without having to find out its IP address?
A: Yes. You may access the local device at http://host:2301; for example, http://127.0.0.1:2301. Also, if you have a proxy server configured in your browser, you may need to add the host (for example, 127.0.0.1) to the list of addresses that should NOT be proxied.

Q: I can successfully access some web-enabled devices, but I cannot access others. Why?
A: If your browser has a proxy server configured, you must enter the address of the web-enabled device in the list of addresses that should NOT be proxied.

Q: When I access a device, I am prompted many times to accept cookies. Why?
A: Browser cookies are required to keep track of user state and security. Cookies must be enabled in the browser, and prompting for acceptance of cookies should be disabled.

Q: I entered a valid Account and Password to change my access level. It was accepted, but the web page still indicates that I only have Anonymous access. Why?
A: This can occur if browser cookies are disabled. Enable Cookies in the browser. They are required for security.

Q: I entered a valid account and password to change my access level, but it reports "Incorrect, try again."
A: Click on the browser Refresh button, and reenter the account and password.

Q: How do I add my own username and password to the device?
A: Only three account names can be used for login access: administrator, operator and user. Passwords for these accounts can be changed by providing the administrator password. Anonymous access to some information is available without logging in. There is no support for individual user accounts. word.

Q: How do I add my own username and password to the device?
A: Only three account names can be used for login access: administrator, operator and user. Passwords for these accounts can be changed by providing the administrator password. Anonymous access to some information is available without logging in. There is no support for individual user accounts.

Note: These user accounts are not connected to OpenVMS accounts in any way.

Q: The Management Agents appear to hang on the Summary page or sometimeson the Device Home page; at other times, I keep getting a login prompt even after I enter login information.
A: You must have a public read community defined.Here is how to do that:

First determine your SNMP settings:

TCPIP> SHOW CONFIGURATION SNMP
or

UCX> SHOW CONFIGURATION SNMP


SNMP Configuration
Flags:
Contact:  test
Location  not defined
Community           Type
public              Read

If you do not see a Community public with type Read, set one up by doing the following:

$TCPIP (or UCX) set configuration snmp/community="public"/type=read

Q: Sometimes I cannot get the agents to run; at other times, I get a login prompt even after I enter login information.
A: If you had our Version 1.0 product installed and you entered a POLYCENTER Software Installation (PCSI) PRODUCT REMOVE command,PCSI does not remove all of the files that the V1.0 productcreated.You must delete the files andreinstall the V2.0 kit:

  1. Stop any running agents from the account in which they were started:

    $ @sys$specific:[wbem]stop_webagents

    Use the DCL command $ SHOW SYSTEM to make sure the agents are stopped.

  2. Delete everything in the SYS$SPECIFIC:[WBEM...] directory.

  3. Reinstall Version 2.0 (refer to the Installation Guide).
Q: I keep getting Java errors or other display errors even after I makethe suggested fixes.
A: Follow these steps:
  1. Clear the cache in your browser. Do this by selecting the Settings option in Internet Explorer (View or Tools, Internet Options, Settings, General, and View Files) and deleting any files that might have been saved.
  2. Delete the references from thebrowser. This is especially necessary if other changes in your environmentwere made and you have not exited from your browser since those changes were made.
  3. Verify that you are running a current or supported browser, or both, that supports dynamicHTML. Compaq Management Agents work with Microsoft Internet Explorer Version 4.01 or later and with Netscape Version 4.5 or later.

Q: I am getting a PCSI error part-way through my installation.

The following product will be installed to destination:    COMPAQ AXPVMS V72_MGMTAGENTS V2.0-16   DISK$ALPHASYS-72:[VMS$COMMON.]Portion done: 0%...10%...20%...30%...40%%PCSI-E-READERR, error reading $6$DKA300:[SYS0.][SYSUPD]COMPAQ-AXPVMS-V72_MGMTAGENTS-V0200-16-1.PCSI;1-DDIS-E-TNF, invalid element syntax%PCSI-E-OPFAILED, operation failedTerminating is strongly recommended.  Do you want to terminate? [YES]%PCSI-E-CANCEL_WIP, termination resulted in an incomplete modification to the system%PCSI-E-S_OPCAN, operation cancelled by request%PCSIUI-E-ABORT, operation terminated due to an unrecoverable error condition

A: You probably have a corrupt kit. The PCSI kit must be infixed-length, 8192-byte CR format. Please verify the file attributes and copy a new kit to your target machine.

Q: I enter everything to start the Management Agents for OpenVMS, but it does not run.
A: Make sure that SNMP is running.

NOTE:

When you enter a problem report, the development engineers will needthe output of some of the following commands for your configuration:

$ PRODUCT SHOW HISTORY/FULL$ SHOW SYSTEM$ SHOW PROCESS QUOTA/ID=(the id for the WBEM$SERVER process)$ SHOW PROCESS ACCOUNT/ID=(the id for the WBEM$SERVER process)$ TCPIP (or $ UCX) SHOW CONFIGURATION SNMP/ALL$ INSTALL LIST SYS$SHARE:PCSI$SHR.EXE$ DIR/PROT SYS$SPECIFIC:[WBEM...]*.HTM$ DIR/PROT SYS$SPECIFIC:[000000]WBEM.DIR$ DIR/PROT SYS$SPECIFIC:[WBEM]*.DIR$ TCPIP (or $ UCX) SHOW VERSION/ALL
