Installation Planning for NetView Web Application

The NetView Web application is available on the following platforms:

• Windows^(R)
• AIX^(R)
• Linux^(R) for zSeries^(R)
• Linux on x86-32/x86-64

The NetView Web application consists of the following 4 components:

• WebSphere^(R) Enterprise Archive (EAR) file
• Web XML Editor Utility
• Readme Documentation (this file)
• Embedded version of the IBM^(R) WebSphere Application Server v7.0

Before installing the NetView Web application, you must decide if you want to use the Embedded version of the IBM WebSphere Application Server v7.0 or the IBM WebSphere Application Server as your web server. The Embedded version of the IBM WebSphere Application Server v7.0 image is installed as a 32-bit configuration. This embedded version of the WebSphere is integrated within the installation/package self-extracting image of NetView Web Application. The machine where the Embedded version of the IBM WebSphere Application Server v7.0 or IBM WebSphere Application Server is installed is referred to as the Web Application Server.

During the installation process, the InstallShield InstallAnywhere wizard will guide you through a series of short steps to determine your setup preferences. If you select "Yes, install embedded version of WebSphere", then all components (4) of the NetView Web app will be installed and configured. If you select "No, I already have WebSphere installed", then only 3 components will be be installed (installation and configuration of the Embedded version of the IBM WebSphere Application Server will not take place).

The specific level of the Embedded version of the IBM WebSphere Application Server v7.0 component which is shipped as part of the install image is v7.0.0.39.
Detailed version information is as follows:

Name:               IBM Embeddable WebSphere Application Server
Version:           7.0.0.39
ID:                    embeddedEXPRESS

Refer to the IBM Tivoli NetView for z/OS Installation: Configuring Additional Components manual for more information.

Prerequisites

Software Requirements

If you are using WebSphere as your web server, IBM WebSphere Application Server, v7.0 is required. The specific tested and supported level of WebSphere is v7.0.

If you decided to use the Embedded version of the IBM WebSphere Application Server v7.0 (which is an installable component of NetView Web application) as your web server, then there is no need for another or separate WebSphere Application Server.

The NetView Web application Japanese version is only supported when connected to the NetView for z/OS Japanese version. The NetView Web application English version is only supported when connected to the NetView for z/OS English version.

The final install footprint is about 800 MB of fixed disk space for Windows and 950 MB for UNIX systems.
Important Note: During installation and deployment of the NetView Web application, system temp (%TEMP%) space on Windows and /tmp filesystem on UNIX will increase the total disk space requirements. Also, the target installation directory will require more disk space during the deployment phase than what is noted for the final install footprint. Based on this, it is recommended that your system have at least 1.5 GB for temp space and an additional 1.5 GB for the target installation directory.

It is recommended for your Windows or UNIX system to have at least 2 GB of memory. It is very important to have at least 2 GB of virtual memory available for the NetView Web application when installing on the platform Linux on zSeries.

The NetView Web application is supported on the following operating systems:

Selecting the Correct files

The files to install are located in the Tivoli NetView for z/OS DVD distribution media under the directory "webapp".

The following files are distributed as part of the NetView Web application:

Installing/Uninstalling the NetView Web Application

General information concerning Installing and Uninstalling the NetView Web Application

• The wizard for the uninstall process will guide you through the uninstall by prompting you to provide information in each wizard panel.
• During uninstall processing, the InstallAnywhere wizard does not remove files that were not originally installed by InstallAnywhere.
• Before attempting the uninstall, make sure you save any customized files that you may want to keep (e.g., the web.xml file that you modified for your environment).
• If you have previously installed the Embedded version of the IBM WebSphere Application Server v7.0 component, you must first end the web application server (server1) if it is still active before continuing with the uninstall.

• For instructions to run the NetView Web application web server as a Windows service, see section below under "Hints and Tips" called Setting up Web Application webserver to run as a Windows service.
• For silent or unattended installation of NetView Web application component, see InstallAnywhere template file in the "doc" subdirectory under your installation location. The file is called "znetview_webapp_silent_install.rsp" and contains all the necessary instructions and information about running a silent install on any supported platform. This file is also available on the DVD media under "webapp" subdirectory.
• For console mode (non-GUI interface) installations, invoke the installer with "-i console" option. Example below is for AIX platform:

  ./znetview_webapp_aix.bin -i console
  

  (console mode invocation with "-i console" option can also be used with the uninstall launcher as well)

• The installation wizard, InstallShield InstallAnywhere will guide you through the install process by prompting you to provide information in each wizard panel.
• Notes concerning SECURE and NON-SECURE selections for configuring your CONNECTION:

The default choice for the installation wizard is SECURE CONNECTION when running the NetView Web application with the Embedded version of the IBM WebSphere Application Server v7.0.

• If SECURE CONNECTION is configured, then the HTTPS Transport Port value (specified in the previous panel: default is 9943) is the port number for the URL to run the Web application. See the section below entitled "Starting your Internet Browser" for details. Selecting SECURE CONNECTION will only allow HTTPS access since HTTP transport will be disabled.

  Sample URL   (notice the "s" with this protocol https !):
  https://hostname:9943/netview/NetView4zosDomain/      (secure connection)

• If NON-SECURE CONNECTION is configured, then both HTTP and HTTPS transports are enabled. This means that you can run the Web application using either HTTPS Transport Port value (default is 9943) or HTTP Transport Port value (default is 9980).

  Sample URL   (either one will provide access):
  http://hostname:9980/netview/NetView4zosDomain/        (non-secure connection) https://hostname:9943/netview/NetView4zosDomain/      (secure connection)

Note: If after installation of the Embedded version of the IBM WebSphere Application Server v7.0 component, you then decide that you want to change your CONNECTION from SECURE to NON-SECURE or NON-SECURE to SECURE, then use the "secure script" to make this change. See the section below labeled "Using the secure script:" under Configuring the Embedded version of the IBM WebSphere Application Server v7.0 for details.

• As a general rule for each of the installation sections below, uninstall the product before attempting any new installation.
• For installation debug purposes, there is a log file in the installation home directory named NetView_Web_Application_InstallLog.log.
  Also, an additional accumulative log file named webapp_installer.log can be located in c:\tmp for Windows and /tmp for Unix.

  It is possible that these files may need to be examined by the NetView service support team if any installation errors occur.

Note: You might want to first save any customizations made to the web.xml file before proceeding with the rest of these instructions.

• On the Administrator's Console, go to Applications -> Enterprise Applications.
• Select NetView Web Application and click Stop.
• Once the NetView Web Application has stopped, select it again, and click Uninstall.
• Save the changes.

Note: Uninstalling the zNetViewWebApp.ear file from WebSphere Application Server does not uninstall any of the NetView WebSphere application components previously installed. To uninstall the NetView WebSphere application, see the Installing/Uninstalling the NetView Web Application section for your platform.

• It will be necessary to modify the web.xml file in the WEB-INF directory before starting the NetView Web application. For a deployment within an application server, the full path to this file will be as follows:
  websphere_installation_path/profiles/profile/config/cells/Node/applications/NetView Web Application.ear/deployments/NetView Web Application/zNetViewWebApp.war/WEB-INF
  where:
  websphere_installation_path is the install location of WebSphere Application Server.
  profile is the profile of the WebSphere application server running on Node.
  Node is the Node name where the WebSphere application server resides.

• It is recommended that you use the Web XML Editor Utility to modify your web.xml file. See "Starting the Web XML Editor Utility" under the section Starting/Stopping the NetView Web Application for information regarding this utility.

• You must create a uniquely named servlet definition and url-pattern for each NetView for z/OS domain that you want to communicate with. The default domain used in the web.xml file is cnm01. Using the servlet definition section named cnm01_ZnvAccessServlet as your template, create a uniquely named section for each of your NetView domains. Only create a single servlet definition for each NetView domain; however, you can define multiple url-patterns that point to each servlet. The domain portion of the url-pattern cannot be mixed case. Note: If you are not using the Web XML Editor Utility, the url-pattern is part of the servlet-mapping element. Be sure to provide equivalent url-pattern tags creating the URL with the domain in lowercase and another with the domain in uppercase. The Web XML Editor Utility will automatically do this for you.

• Modify the value of the HOST parameter to be the fully qualified hostname of your NetView for z/OS domain (for example, netviewhost.subnet.company.com). Change the value of the ZNV_DOMAIN parameter to be the NetView for z/OS domain name. Modify PORT, INKEY and OUTKEY as appropriate for your installation.

• You must also create a uniquely named url-pattern for each z/NetView. Change the value of the url-pattern for the ZnvAccessServlet to the same value you assigned to ZNV_DOMAIN parameter.

For more information, refer to the IBM Tivoli NetView for z/OS Installation: Configuring Additional Components manual.

Post-Installation Customizations for the Embedded version of the IBM WebSphere Application Server v7.0

• It will be necessary to modify the web.xml file in the WEB-INF directory before starting the Web Application Server. If you have chosen the default target directory during installation, the full path to this file will be as follows:
  \usr\lpp\netview\v6r1\ewas\profiles\profile1\installedApps\DefaultNode\zNetViewWebApp.ear\zNetViewWebApp.war\WEB-INF

• It is recommended that you use the Web XML Editor Utility to modify your web.xml file. See "Starting the Web XML Editor Utility" under the section Starting/Stopping the NetView Web Application for information regarding this utility.

• You must create a uniquely named servlet definition and url-pattern for each NetView for z/OS domain that you want to communicate with. The default domain used in the web.xml file is cnm01. Using the servlet definition section named cnm01_ZnvAccessServlet as your template, create a uniquely named section for each of your NetView domains. Only create a single servlet definition for each NetView domain; however, you can define multiple url-patterns that point to each servlet. Note: If you are not using the Web XML Editor Utility, the url-pattern is part of the servlet-mapping element.

• Modify the value of the HOST parameter to be the fully qualified hostname of your NetView for z/OS domain (for example, netviewhost.subnet.company.com). Change the value of the ZNV_DOMAIN parameter to be the NetView for z/OS domain name. Modify PORT, INKEY and OUTKEY as appropriate for your installation.

• You must also create a uniquely named url-pattern for each z/NetView. Change the value of the url-pattern for the ZnvAccessServlet to the same value you assigned to ZNV_DOMAIN parameter.

For more information, refer to the IBM Tivoli NetView for z/OS Installation: Configuring Additional Components manual.

Security Enhancements

Securing logon to the NetView for z/OS host

The NetView Web application user logon security has been enhanced.

If a user cannot logon to the NetView host from the NetView Web application, it may be that their user ID has been locked out due to five consecutive unsuccessful logon attempts. This would be indicated by the user being redirected to the web site http://www.ibm.com upon attempting to logon to the NetView host. If a user gets locked out, the administrator can locate the following directory:

install_location/ewas/profiles/profile
and delete the file named userid_domain_settings.xml

Do not modify the userid_domain_settings.xml file manually as that can lead to unexpected results.

The browser instance, which was in use when the NetView user ID lock out occurred, must be closed and a new browser instance started.

Try the logon to the NetView host again with a new browser instance.

Starting/Stopping the NetView Web Application

The nvsrvc Command

nvsrvc start webserver OR, simply
nvsrvc start
This will start the Embedded version of the IBM WebSphere Application Server v7.0. The Web Application server is started when a message stating "Server open for e-business" is issued.
A log file will be created in \usr\lpp\netview\v6r1\ewas\logs when the z/NetView Web Application is accessed:

netviewservlets.log - This log contains information, warning and error messages generated during NetView Web application server initialization or processing.

The Embedded version of the IBM WebSphere Application Server v7.0 provides log files in the \usr\lpp\netview\v6r1\ewas\profiles\profile1\logs\server1 directory. The SystemOut.log file is the main log file for application server operations.

To display help for this command, issue the nvsrvc command without any parameters.

Configuring the Embedded version of the IBM WebSphere Application Server v7.0

• Using the secure script:

You can set the CONNECTION type to SECURE or NON-SECURE when running the NetView Web application within the Embedded version of the IBM WebSphere Application Server v7.0 component at any time by using a tool in the "bin" subdirectory of the NetView Web application installed location. For Windows, the script tool is called "secure.bat". For Unix it is "secure.sh".

Only options for the secure script are "y" or "n". Running the script without any parameters will display the available options with a brief description.

• y  option enables only https access and disables http access for the NetView Web application.
• n  option enables both https and http accesses for the NetView Web application.

For example, if you wanted to set the CONNECTION for the NetView Web application to NON-SECURE on AIX, then you would issue the following command from the ../bin subdirectory:

"./secure.sh  n"

Refer to "Notes concerning SECURE and NON-SECURE selections for configuring your CONNECTION" in the section above under Install - Important Information concerning the details that will affect your URL access (http vs. https) and port number.

• Session Timeout:
To set a new value for session timeout, edit the following file in installation_location\ewas\profiles\profile1\config\cells\DefaultNode\nodes\DefaultNode\servers\server1\server.xml
where installation_location is the install location previously specified (default is c:\usr\lpp\netview\v6r1 for windows and /usr/lpp/netview/v6r1 for unix)

In this server.xml file, look for string invalidationTimeout. Default value is 30. Change this value, save the file and then stop/start the web server to enable the change to take place.

(It is recommended that you make a backup of this file before saving any changes)

• Port Values:

Current values of ports values set during the installation can be queried by examining the portdef.props file in the installation_location\properties subdirectory.

Common port values to change are WC_defaulthost (default is 9980) and WC_defaulthost_secure (default is 9943).
You can modify these two values by editing the following three files, searching for their strings, saving your changes, and then stop/start the web server to enable the changes to take place.

The three files are:

installation_location\ewas\profiles\profile1\config\cells\DefaultNode\nodes\DefaultNode\serverindex.xml
installation_location\ewas\profiles\profile1\config\cells\DefaultNode\virtualhosts.xml
installation_location\ewas\profiles\profile1\config\templates\servertypes\APPLICATION_SERVER\serverindex.xml

(It is recommended that you make backups of all three files before saving any changes)

Starting the Embedded version of the IBM WebSphere Application Server v7.0

Windows Environment - execute the following:

cd D:\usr\lpp\netview\v6r1\bin
nvsrvc start webserver      (or just nvsrvc start)

UNIX Environment - execute the following:

cd /usr/lpp/netview/v6r1/bin
./nvsrvc.sh start webserver      (or just ./nvsrvc.sh start)

Starting the Web XML Editor Utility

Use the following command to start the utility.
   Note: D: drive is used as an example drive in the command below.

Windows Environment - execute the following:
cd D:\usr\lpp\netview\v6r1\wxe\bin
WxeEditor.bat

UNIX Environment - execute the following:

cd /usr/lpp/netview/v6r1/wxe/bin
./WxeEditor.sh

Important note: When running the Web XML Editor Utility (WxeEditor.sh) on UNIX systems, which may not have a common desktop environment (e.g. Linux on zSeries), it is important that the display be previously configured to handle X-Windows or X11 GUI applications. Any RPM package installations, tools, and configuration needed to export the display properly in this context is beyond the scope of IBM's responsibilities.

Starting your Internet Browser

To display the sign-on panel for the NetView Web application from your Internet Browser (Mozilla or Internet Explorer), task DSIWBTSK must be ACTIVE on the NetView for z/OS system.

If you are using the Embedded version of the IBM WebSphere Application Server v7.0, point your web browser to:

https://hostname:9943/netview/NetView4zosDomain/

If you are using WebSphere, point your web browser to http://hostname:portnumber/netview/NetView4zosDomain/
If you configure your HTTP web server and WebSphere Application Server to use a port other than the default of 80, then you will need to specify that port in the URL after the hostname. Note that hostname and port must be separated by a colon.

hostname is the hostname of the machine where your Web Application code is installed. If you are running everything locally, you can specify localhost as your hostname.

portnumber is the port number for the application server's internal HTTP or HTTPS transport connection.

NetView4zosDomain is the name that you specified in the servlet-mapping definition in the web.xml file (if you are using the Embedded version of the IBM WebSphere Application Server v7.0) or the value that you supplied when performing the pre-installation steps for WebSphere. If you have followed the customization steps above, this will be the NetView for z/OS domain name.

Sign on to NetView using a valid user name (NetView operator ID) and password.

Special Considerations for DBCS Japanese environment

The following items describe some situations that need to be considered when operating NetView Web application in a supported Japanese environment:

• Editing the web.xml file on a Japanese windows operating system:

Do not use wordpad since some Japanese characters will be incorrectly converted from UTF-8 format when saving the file. It is recommended to use another editor that can handle UTF-8 locale.

Hints and Tips

• Setting up Web Application webserver to run as a Windows service.

This section describes the information necessary for installing and starting NetView Web application webserver (WebSphere app server, server1) as a Windows service for the installed component "Embedded version of the IBM WebSphere Application Server v7.0".

Initial assumptions for the NetViewWebApp Windows service:

This first step is important since you want to make sure that the webserver is functioning properly in normal usage (not as a Windows service):
• It is assumed at this point that "nvsrvc start webserver" successfully starts the WebSphere app server, server1.
• Also, it is assumed that another system can access the webserver remotely and signon to the Web application via its browser. This means that all the setup work for web.xml has been completed correctly.

Installing the NetViewWebApp Windows service:

(Default installation location is used throught for the example. Run all commands from a command prompt windows)
• cd c:\usr\lpp\netview\v6r1\bin
• WASService_wrapper.bat

After running the batch file, you should see a final displayed message:
"IBM WebSphere Application Server v7.0 - NetViewWebApp service successfully added."

Our webserver is now a windows service called "NetViewWebApp". The name to look for in the windows "Services" panel is the full title:
"IBM WebSphere Application Server v7.0 - NetViewWebApp".

Starting the NetViewWebApp Windows service:

• cd c:\usr\lpp\netview\v6r1\ewas\bin
• WASService -start NetViewWebApp

Now you can start/stop/disable this "NetViewWebApp" service from the Services panel or change directory into C:\usr\lpp\netview\v6r1\ewas\bin and run "WASService.exe" and it'll display other options that can be run from the command prompt (like those in the Service panel).

Using the NetViewWebApp Windows service:

• Reboot, but do not logon to your system:
After reboot, let the system quiesce a bit at Windows logon prompt, but do not logon. Wait for disk activity to level off since the webserver is starting under the Windows service.
• Try accessing the Web App via browser from other system:

Problem Determination for the NetViewWebApp Windows service:

If the Web App fails to display the NetView signon panel in the browser, then
• Possibly give more time for the Windows service to complete the initialization of the webserver.
• Log onto the PC running the NetViewWebApp Windows service and examine the nvsrvc.log file in C:\usr\lpp\netview\v6r1\bin. Nvsrvc.log should show status: Server server1 open for e-business
• See points listed above under subtopic "Initial assumptions for the NetViewWebApp Windows service".

Removing the NetViewWebApp Windows service:

To uninstall this Windows service previously installed, issue the following command from the c:\usr\lpp\netview\v6r1\ewas\bin directory:
WASService -remove NetViewWebApp

Known Defects

• Problems with "Save as" in Web XML Editor Utility

  When using the "Save as" feature with the utility, there are some problems related to the Java runtime. You can only "save as" to the current directory as shown in the open file window or to a file that already exists.

• Hot links not working for Japanese help panel in Japanese web browser

  The resulting data is corrupt when using "Search" against a command in the field "Enter a command or message" in the secondary web browser panel. This panel displays when, from a Japanese web browser, the "NetView Help" option (under the "NetView Support" heading) is selected on the main Tivoli NetView Welcome panel.

  An alternative work-around is to issue this same command (as displayed from the "NetView Help" panel) from NCCF or NetView command line.

• Error message displayed in English language in Japanese web browser

  When using the Japanese web browser, and your credentials are removed (for example, you click on the Sign Off hot link) or expired, and you attempt to display another NetView web page, the error message "CNM1210E No credentials exists to access NetView for z/OS CNM01." will be displayed in English in the browser.
