This chapter describes how to prepare and run the ACMS Remote Manager web agent.

3.1 Overview of the Remote Manager Web Agent

With the Remote Manager web agent, system managers can use their web browser to monitor and tune remote ACMS systems. The ACMS for OpenVMS Alpha Development and Run-time kits include the Remote Manager Hyper-Media Management Object (HMMO), which is integrated into the Compaq web-based enterprise management (WBEM) environment. Known as the Remote Manager web agent, this object functions as a Remote Manager client through the ONC RPC interface.

The Remote Manager web agent environment consists of the following host systems:

• Web client -- One or more local systems running a web browser that supports Java plug-ins, JavaScript, and Cascading Style Sheets (CSS).
• Web server -- An OpenVMS Alpha system where the web agent (ACMS$MGMT_HMMO) and WBEM management server (WBEM$SERVER) processes are running. This system serves the ACMS Remote Management web page and handles all communication between the web client and Remote Manager server systems.
• Remote Manager server -- One or more OpenVMS Alpha or VAX systems where Remote Manager server processes (ACMS$MGMT_SVR) are running. The ACMS information displayed on the web agent home page is a result of executing ACMSMGR commands on the Remote Manager servers.

As shown in Figure 1-1, the Remote Manager web agent (ACMS$MGMT_HMMO) relies on the WBEM management server (WBEM$SERVER) to relay data to and from the web browser. The web agent uses its internal web server to connect to the ACMS Remote Management page. All command input is then relayed to Remote Manager server through the HMMO.

3.2 Remote Manager Web Agent Setup

Before you begin, you must have already installed OpenVMS Alpha Version 7.2--1 or higher on the web server system. Also, ensure that all web client systems are running one of the currently supported web browsers. See the Compaq ACMS for OpenVMS Software Product Description (SPD 25.50.xx) for a list of the currently supported web browsers.

Once the OpenVMS Alpha software is installed, perform the following steps to set up the Remote Manager web agent on the web server system:

1. Install the Remote Manager web agent software ( Section 3.2.1)
2. Install the Compaq Management Agents for OpenVMS software ( Section 3.2.2)
3. Assign additional rights identifiers ( Section 3.2.3)
4. Start the web agent ( Section 3.2.4)
5. Enable access to Remote Manager hosts ( Section 3.2.5)

The Remote Manager web agent software is bundled with the ACMS for OpenVMS Alpha Run-time and Development kits. To install the web agent software, choose to install the WBEM-related files component of either kit.

This section contains excerpts from an ACMS Development kit installation. Refer to the Compaq ACMS for OpenVMS Version 4.4 Installation Guide for detailed information about the entire ACMS installation procedure.

1. Run the Compaq ACMS for OpenVMS Alpha 4.4 installation procedure for either the ACMS Run-time or Development kit, in as described in Section 3.2.1 of the Compaq ACMS for OpenVMS Version 4.4 Installation Guide. For example:

   $ @SYS$UPDATE:VMSINSTAL ACMSDEVA_044 MTA0: OPTIONS N,AWD=DISK1 OpenVMS AXP Software Product Installation Procedure V7.3 It is 22-JUN-2001 at 11:00. Enter a question mark (?) at any time for help.

2. A series of product-specific questions are displayed that prompt you to choose the appropriate installation options. Answer the following prompts accordingly:

   * Do you want the full ACMS installation [NO]? N * Do you want to install the ACMS component software [YES]? N * Do you want to install the WBEM-related files for ACMS [YES]? Y * Do you want to update the LSE environment for ACMS [YES]? N

   
   The installation procedure then checks for prerequisite software and adequate disk space and lists a summary of the components to be installed, as follows:

   CHECKING INSTALLATION PREREQUISITES ----------------------------------- (required and optional software checked) (product licenses checked) (disk space checked) ACMS PREVIOUS INSTALLATION -------------------------- (previous installation of ACMS is compatible with current installation) ACMS WBEM CHECK -------------- SUMMARY OF THIS ACMS INSTALLATION --------------------------------- The following steps will be taken to complete this installation: o WBEM environment will be updated for ACMS The rest of the installation will take approximately 7 minutes. Note that this time is heavily dependent your system load, hardware and kit media. The time mentioned was measured on a stand-alone DEC 3000 (Alpha) system with a disk-resident kit. Your time may vary.

3. When prompted to continue the installation, answer YES. The procedure enters the ACMS WBEM Setup phase.
4. The WBEM setup procedure (SYS$STARTUP:ACMS$WBEM_SETUP.COM) is then invoked, which creates or updates the ACMS$WBEM account and creates the necessary directories and web agent files.
   Do one of the following:
   • If the account does not exist, you are prompted to supply a UIC and password for the account, as follows:

     The ACMS$WBEM account used to execute ACMSMGR WBEM commands is not available. You must supply a UIC and password for this account so that it can be created. Please enter the UIC for the ACMS$WBEM account, in the form [ggggg,nnnnnn] UIC: [320,525] Please enter a password of at least 8 characters, using only the following characters: ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789$_ Password: Verification:

     
     Enter the appropriate UIC and password. The ACMS$WBEM account is then created and assigned the ACMS$MGMT_READ rights identifier.
   • If the account already exists, a list of the rights identifiers currently assigned to the account are displayed, as follows:

     ****************************************************************** * ACMS WBEM Setup * ****************************************************************** Checking for user account ACMS$WBEM Identifier for ACMS$MGMT_READ exists in RIGHTSLIST Identifier for ACMS$MGMT_WRITE exists in RIGHTSLIST Identifier for ACMS$MGMT_OPER exists in RIGHTSLIST Identifier for ACMS$MGMT_SYSUPD exists in RIGHTSLIST The account ACMS$WBEM exists. The identifiers on the account ACMS$WBEM are Identifier Value Attributes ACMS$MGMT_READ %X8001012E ACMS$MGMT_WRITE %X8001012F ACMS$MGMT_OPER %X80010130 ACMS$MGMT_SYSUPD %X800101DB Do you wish to reset the account ACMS$WBEM to the default values [N] ? y

     
     You can choose to reset the identifiers at this time by answering YES.
   
   The setup procedure then completes by creating the following directories and files on the web server system:

   The ACMS WBEM setup has completed. The following files were copied: To SYS$SYSROOT:[WBEM] ACMS$MGMT_HMMO.EXE RUN_ACMS_HMMO.COM STOP_ACMS_HMMO.COM To SYS$SYSROOT:[WBEM.WEB.IM.ACMSHMMO.ENG] ACMS.CSS ACMSHMMO.JS ACMSMENUTREE.JAR ACMS_BANNER.HTML ACMS_INDEX.HTML ACMS_MENU.HTML ACMS_OUTPUT.HTML To SYS$SYSROOT:[WBEM.WEB.IM.ACMSHMMO.IMAGES] ACMSHMMO.GIF COMPAQLOGO.GIF WEBBUM.GIF To SYS$COMMON:[SYSLIB] ACMS$TRACE_SHR.EXE You may wish to purge these directories.

Once the ACMS installation is complete, download and install the Compaq Management Agent for OpenVMS software, as described in Section 3.2.2.

3.2.2 Install the Compaq Management Agents for OpenVMS Software

If you have not already installed the Compaq Management Agents for OpenVMS software, do so now. You can download this software from the web page listed in Section 3.1.

Follow the associated instructions to copy, unpack, and install the appropriate Compaq Management Agents for OpenVMS PCSI kit. Once the software is installed, issue the following command to start the management agent process:

$  SET DEFAULT SYS$SPECIFIC:[WBEM]
$  @WBEM$RUN_WEBSERVER.COM

Note that the WBEM server (WBEM$SERVER) is the only process started by this procedure. None of the other Management Information Base (MIB) processes included in the WBEM kit (such as, WBEM$CPQHOST) are used by the Remote Manager agent. If you plan to use software on this system that relies on the MIB processes, run the WBEM$STARTUP.COM procedure, as described in the WBEM installation material.

3.2.3 Assign Additional Rights Identifiers

The installation procedure automatically grants the ACMS$MGMT_READ rights identifier to the ACMS$WBEM account when it is created. This enables all SHOW commands to be executed from the web agent. In order to enable all other non-read operations (such as SAVE, SET, START, STOP, RESET, ADD, and DELETE), grant one or more of the following rights identifiers to the ACMS$WBEM account:

• ACMS$MGMT_WRITE
• ACMS$MGMT_OPER
• ACMS$MGMT_SYSUPD

See Section 4.4.2 for more information on the use of rights identifiers.

3.2.4 Start the Remote Manager Web Agent Process

Enter the following command to start the Remote Manager web agent process:

$  SUBMIT/NOTIFY/LOG=SYS$SYSROOT:[WBEM]/QUEUE=queue-name -
_$ /USER=ACMS$WBEM SYS$SPECIFIC:[WBEM]RUN_ACMS_HMMO.COM

where queue-name is a valid OpenVMS batch queue. If the process is already running, this command restarts the process.

3.2.5 Enable Access to Remote Manager Hosts

In order for the Remote Manager web agent to access a Remote Manager server system, the logical ACMS$MGMT_ALLOW_PROXY_ACCESS on the host system must be set to a value of 1, which enables proxy access.

Also, an ACMS proxy entry for the ACMS$WBEM account is required. For example, the following proxy entry grants the user ACMS$WBEM access to the local host from any known system:

$ MCR ACMSUDU

UDU>SHOW /PROXY *::ACMS$WBEM
Remote User: *::ACMS$WBEM               Local User: ACMS$WBEM

The rights identifiers on the local ACMS$WBEM account control the level of access allowed on the host system.

Use the following command to stop the web agent process:

$  @SYS$SPECIFIC:[WBEM]STOP_ACMS_HMMO.COM

If you also want to stop the WBEM server process, enter the following command:

$  @SYS$SPECIFIC:[WBEM]WBEM$STOP_WEBSERVER.COM

The following sections describe how to access and use the Remote Manager web agent interface.

3.3.1 Accessing the ACMS Remote Management Web Page

From a browser on the web client system, enter the following URL to connect to the web server system:

http://server-host:2301/acmshmmo/eng/acms_index.html

   node (node name)
   node.company.com (URL)
   165.112.94.78 (IP address)

The ACMS Remote Management page is displayed, similar to Figure 3-1.

Figure 3-1 Remote Manager Web Agent Page

This page consists of the following frames:

• Banner frame
  Displays the application name as well as the name of the web server system. This frame also contains a link that you can use to send feedback about the web agent directly to Compaq.
• Command Selection frame
  Displays a tree that contains selections representing the various ACMSMGR commands. The items in this tree are grouped by common command verbs (such as, SHOW and SET) or by object (such, as Remote Manager). This frame also contains a series of links to pertinent Compaq WBEM and ACMS information, such as to the HTML version of this guide.
• Output frame
  Displays the results of the selected command. Brief instructions on how to interact with the data in this frame are displayed along with the related output and status messages (if any).

The web agent uses color and font highlighting to indicate the different states and types of data displayed in the output frame. The default conventions are described in Table 3-1. Note, however, that you can change these conventions as described in the following section.

The Remote Management web page relies on a cascading style sheet (CSS) to manage its formatting. Based on the CSS level 2 specification (CSS2) from the World Wide Web Consortium (W3C), the ACMS.CSS file functions as a template for information displayed in the output frame.

If you are familiar with CSS files, you can customize the formatting of information in the output frame by editing the file ACMS.CSS located in SYS$SYSROOT:[WBEM.WEB.IM.ACMSHMMO.ENG].

For example, to remove the background image in the output frame, open the CSS file and search for the following statement:

BODY {background-color: white; background-image:
url(/acmshmmo/images/webbum.gif); color: black;}

Replace this statement with the following:

BODY {background-color: white;  color: black;}

To learn more about CSS files or the CSS2 specification, visit the W3C web site for the latest information and resource listings:

http://www.w3.org/Style/CSS

When you first access the ACMS Remote Management web page, the name of the web server is displayed as the Remote Manager host.

To choose a different Remote Manager host, click the Change button in the command selection frame. The Select Host popup window is displayed, similar to Figure 3-2.

Figure 3-2 Select Host

Enter the name of the Remote Manager host, and click OK. Note that if you enter a URL or IP address, only the short form of the name is displayed in the command selection frame.

3.4 Issuing Remote Manager Commands

The Remote Manager web agent interface provides detailed usage instructions on each page displayed within the output frame. Therefore, the following sections are only intended to provide a brief overview of issuing the most common Remote Manager commands with the web agent.

The Remote Manager web agent interface provides you with much of the same capability as ACMSMGR in managing ACMS systems. The main functional differences are that with the web agent:

• You cannot view TRAP information.
• There is no equivalent to the SHOW LOG/LOCAL and SHOW ERROR/LOCAL commands.
• You can only connect to one Remote Manager host system per window.

You can quickly reissue any web agent command using the Refresh (or Reload) option of your browser to reload the page in the output frame. To save frequently issued commands, bookmark the page in the output frame.

For detailed information about the function of each command, see Chapter 11.

3.4.1 Using Show Commands

To display information about an ACMS entity or object:

1. In the command selection frame, click Show to expand the list of valid entities and Remote Manager objects.
2. Click on the appropriate entity (such as, TSC) or object (such as, Process). If you selected an entity, click on the appropriate type of information to display (such as, Config), and choose the scope of display (such as, Brief/Stored).
   The results of the command are displayed in the output frame, similar to Figure 3-3. Note that all dynamic data is displayed in italics.

Figure 3-3 Show TSC

To change information related to an ACMS entity or Remote Manager object:

1. In the command selection frame, click Set to expand the list of valid entities and Remote Manager objects.
2. Click on the appropriate entity (such as, ACC) or object (such as, Remote Manager > Collection). If you selected an entity, click on the appropriate type of information you want to change (such as, ACMSGEN).
   The available values are displayed in the output frame, similar to Figure 3-4. Note that any active and stored data that can be changed is displayed reverse highlight.

3. Move the cursor over the value you want to change until the link cursor appears, and then click on the value. A popup window is displayed prompting you for a new value.
4. Enter the new value in the popup window, and click OK.

Note that you can update the values displayed in the output frame at any time by clicking the Refresh button.

3.4.3 Using Start and Stop Commands

To start or stop an ACMS object, such as an application (EXC):

1. In the command selection frame, click Start or Stop to expand the list of objects.
2. Click on the appropriate object (such as, Remote Manager > Collection).
   Except for System, the command is executed as soon as it is selected. If you chose Start or Stop System, additional choices are displayed in the output frame.
3. Click on the appropriate check boxes to set or unset one or more values, and click the Start SYSTEM or Stop SYSTEM button.

To add or delete a Remote Manager object, such as an error filter:

1. In the command selection frame, click on the appropriate entry, either Error Management or Remote Manager.
2. Click on the subentries until you reach the item you want to add or delete (such as, Add Filter).
   A form with related parameter information is displayed, similar to Figure 3-5.

   Figure 3-5 Add Error Filter

   ---

   
3. Complete form and click Add or Delete.

3.5 Troubleshooting the Remote Manager Web Agent

• WBEM Home Page does not display the ACMS Icon
  ACMS HMMO is not registered with the WBEM$SERVER process. After starting the WBEM server with the following command:

  $ @SYS$SPECIFIC:[WBEM]WBEM$RUN_WEBSERVER.COM

  
  You may need to delay starting the ACMS HMMO until the WBEM$SERVER process is in the HIB state. If the ACMS HMMO is started too soon it may not register with the WBEM$SERVER. The SYS$SPECIFIC:[WBEM]WBEM$RUN_WEBSERVER.COM must be run prior to running SYS$SPECIFIC:[WBEM]RUN_ACMS_HMMO.COM.
• WBEM Home Page does not display
  If you access the WBEM Home Page at http://host_name:2301/, and the page does not display, it may be that the WBEM$SERVER is not started. Another possibility is that the ACMS$MGMT_HMMO process was started prior to the WBEM$SERVER process. To ensure proper startup, stop both processes and then restart them in the correct order.
• Remote Manager web page displays, but remote commands fail.
  This indicates that the Remote Manager web agent cannot connect to the specified Remote Manager server host. If all commands fail, ensure that the Remote Manager server process is running on the host system and that access to it has been properly setup (as described in Section 3.2.5. If some commands work and others fail, the ACMS$WBEM account may not have the required rights identifier; see Section 3.2.3.
• Page Refresh or Reload does not update the output frame.
  This behavior is browser dependent. To refresh the information displayed in the output frame, move the cursor inside the frame to specifically refresh or reload the information within it.
