Installation Planning for NetView Web Application
The NetView Web application is available on the following three platforms:
The NetView Web application consists of the following four features:
If you choose to do a full installation, all three of these features will be installed. If you choose to do a custom installation, you can specify which features you want to install.
Before installing the NetView Web application, you must decide if you want to use Jetty or WebSphere as your web server. The machine where Jetty or WebSphere is installed is referred to as the Web Application Server.
Once you have determined which web server to use, you must decide if you want to install the SNMP Server on the Web Application Server or a separate machine. Refer to the Installation: Configuring Additional Components manual for more information regarding this.

Installing the NetView Web Application/Uninstalling the NetView Web Application
Note 1: As a general rule for each of the installation sections below, uninstall the product before attempting any new installation.
Note 2: Before attempting the uninstall, make sure you save any customized files that you may want to keep (for example, the web.xml file that you modified for your environment).
Note 3: Important information for installing on Unix systems:
To install the NetView Web application on Windows Server, follow these steps:
Installation Tips:
---- or ----
Note:
When you run zNetViewWebAppWin32_en.exe for Windows, you get an initial InstallShield panel
that prepares a JVM (Java Virtual Machine) to be used for the installation.
Depending upon your machine's speed and memory and other processes currently running
and competing for machine resources, this preparation could take 30 - 40 seconds or
longer. The "status" indicator may freeze for a moment, but give it a chance and
you should get to the next panel which starts the InstallShield Wizard initialization.
It is recommended, but not necessary, to use the default directory name of the target
folder. The default path is "c:\usr\lpp\netview\v5r1". It is important not to use
special characters like &, *, or # as part of the target folder path name.
To uninstall the NetView Web application from Windows Server, follow these steps:
Note:
DO NOT remove any installed files or folders (subdirectories) without first completing
the "Add/Remove Program" process described in step #1 above.
Also, if you have made any important updates to the web.xml file, you might want to save this file before uninstalling the product.
To install the NetView Web application on AIX, follow these steps:
Installation Tips:
If the NetView Web application is installed, then the command should return the following:
"nv.web.app.prod 5.1.0.x C NetView Web Application Prod"
AIX uses the /tmp area for its temp JVM (Java Virtual Machine) area and NetView Web application files during installation so you should plan for at least an extra 77 MB of additional free space in the /tmp file system for a Full Installation. The /tmp space will be released after the installation completes successfully. As for your target directory, you'll need at least 62 MB for a Full Installation.
---- or ----
Note:
When you invoke zNetViewWebAppAIX_en.bin, AIX will display the following status messages:
Initializing InstallShield Wizard Installer...
Preparing Java(tm) Virtual Machine...
...................................
...................................
.........................
Running InstallShield Wizard Installer...
The InstallShield panels that follow with the AIX installation are
similar to the Window's version.
It is recommended, but not required, to use the default directory name of the target folder. The default path is "/usr/lpp/netview/v5r1".
To uninstall the NetView Web application from AIX, follow these steps:
InstallShield will run the uninstall program which will present you with panel information that will let you select the feature(s) that you want uninstalled.
Note:
DO NOT remove any installed files or subdirectories without first running the
InstallShield's uninstaller file zNetViewWebAppUninstall.bin as described in step #1 above.
Do not attempt to uninstall the NetView Web application product via "installp -u" or through the SMIT/SMITTY interface.
Also, if you have made any important updates to the web.xml file, you might want to save this file before uninstalling the product.
To install the NetView Web application on your Linux system follow these steps:
First see important Note #3 in the above section "Important information for installing on Unix systems".
Linux uses the /tmp area for its temp JVM (Java Virtual Machine) area and NetView Web application files during installation so you should plan for at least an extra 77 MB of additional free space in the /tmp file system for a Full Installation. The /tmp space will be released after the installation completes successfully. As for your target directory, you'll need at least 62 MB for a Full Installation.
Note:
When you invoke zNetViewWebAppzLinux_en.bin, Linux will display the following status messages:
Initializing InstallShield Wizard Installer...
Preparing Java(tm) Virtual Machine...
...................................
...................................
.........................
Running InstallShield Wizard Installer...
The InstallShield panels that follow with this installation are
similar to the Window's version.
It is recommended, but not required, to use the default directory name of the target folder. The default path is "/usr/lpp/netview/v5r1".
To uninstall the NetView Web application on from your Linux system follow the these steps:
Note:
During the uninstall process, you may notice several messages similar to:
"cannot remove /usr/lpp/netview/v5r1/log - directory not empty"
This is not a problem since the post-uninstall processing within RedHat Package
Manager will complete the removal of all NetView Web application files and subdirectories.
InstallShield will run the uninstall program which will present you with panel information that will let you select the feature(s) that you want uninstalled.
Note:
DO NOT remove any installed files or subdirectories without first running the
InstallShield's uninstaller file zNetViewWebAppUninstall.bin as described in step #1 above.
Also, if you have made any important updates to the web.xml file, you might want to save this file before uninstalling the product.
Post-Installation Customization for NetView Web Application
If you are using the Jetty Web Server, it will be necessary to modify the web.xml file in the WEB-INF directory before starting Jetty. If you have chosen the default target directory during installation, the full path to this file will be usr\lpp\netview\v5r1\www\webapps\netview\WEB-INF. Although it is recommended to use the Web XML Editor Utility, you can use any ASCII editor to modify the web.xml file. Sections that need to be modified have been preceded with comments so they can be located easily.
It is recommended that you use the Web XML Editor Utility to modify your web.xml file. See "Modify the web.xml File" under the section Using the Web XML Editor Utility to edit the web.xml file for information regarding this utility.
If you are using WebSphere, it will be necessary to modify the web.xml file that is imbedded in the zNetViewWebApp.ear file. If you have chosen the default target directory during installation, the full path to this file will be usr\lpp\netview\v5r1\ears. Although it is recommended to used Web XML Editor Utility, you can use the WebSphere Application Assembly Tool to modify the web.xml file for use with WebSphere. If you plan to use the Web XML Editor Utility, skip to the section titled Installing the Enterprise Application (.ear file) with the WebSphere Enterprise Application Wizard. Otherwise, continue to the next section.
If you need to have access to more than one NetView host, you will need to add additional access servlet definitions under the Web Components portion of the tree on the left in the Application Assembly tool. Only create a single servlet definition for each NetView domain; however, you can define multiple servlet-mappings that point to each servlet. Following are instructions for doing so after starting the Application Assembly Tool.
Starting/Stopping the NetView Web Application
This will start the Jetty Web Server and the SNMP Server.
To display help for this command, issue the nvsrvc command without any parameters.
Windows Environment - execute the following:
D:\usr\lpp\netview\v5r1\bin\nvsrvc start
-- OR --
cd D:\usr\lpp\netview\v5r1\bin
nvsrvc start webserver
UNIX Environment - execute the following:
/usr/lpp/netview/v5r1/bin/nvsrvc.sh start
-- OR --
cd /usr/lpp/netview/v5r1/bin
nvsrvc.sh start webserver
UNIX Environment - execute the following:
/usr/lpp/netview/v5r1/bin\nvsrvc.sh start
-- OR --
cd /usr/lpp/netview/v5r1/bin
nvsrvc.sh start snmpserver
Use the following command to start the utility.
Note: D: drive is used as an example drive in the command below.
UNIX Environment - execute the following:
cd /usr/lpp/netview/v5r1/wxe/bin
WxeEditor.sh
To display the 'Welcome to NetView' screen from your Internet Browser (Netscape or Internet Explorer), task DSIWBTSK must be ACTIVE on the NetView for z/OS system.
If you are using Jetty, point your web browser to http://hostname:8080/netview/servletMappingName/
Note that port 8080 is the default port specified in the jetty.xml file. If you have modified this file to use
a different port you must specify that port in the URL.
If you are using WebSphere, point your web browser to http://hostname/netview/servletMappingName/
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.
servletMappingName is the name that you specified in the servlet-mapping definition in the web.xml file (if you are using Jetty) 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. NOTE that the SLASH ('/') at the end of the URL is REQUIRED.
Sign on to NetView using a valid user name (NetView operator ID) and password.
Modifying the Default MIB Definitions
The NetView Web application is shipped with a default set of MIB definitions which are included when you start the SNMP Server. MIB definitions are specified in a file named mibserver.def which resides in the usr\lpp\netview\v5r1\mibs directory. The mibserver.def file can be modified to include additional MIB definitions or exclude existing MIB definitions. Refer to the mibserver.def file for the complete list of MIBs shipped with the NetView Web Application.
Hints and Tips for the NetView Web Application
The log file for servlet processing is named netviewservlets.log and it resides in /usr/lpp/netview/v5r1/www/logs. If you wish to enable debugging for classes under com.tivoli.netview.snmp you need to change the word 'INFO' to 'DEBUG' in the following line in the log4j.properties file in /usr/lpp/netview/v5r1/www/classes.
log4j.category.com.tivoli.netview.snmp=INFO
The log file for the SNMP Server is named snmpserver.log and it resides in /usr/lpp/netview/v5r1/jars/logs. If you wish to enable debugging for classes under com.tivoli.netview.snmp and under ibm.nways.jdm you need to change the word 'INFO' to 'DEBUG' in the following two lines in the snmpserver-log4j.properties file in /usr/lpp/netview/v5r1/jars/logs.
log4j.category.com.tivoli.netview.snmp=INFO
log4j.category.ibm.nways.jdm=INFO
The default size for netviewservlets.log and snmpserver.log is 100KB. Once a log is full, it is renamed with a '.1' suffix and a new '.log' file is created.
The log4j.properties file in /usr/lpp/netview/v5r1/www/classes and the snmpserver-log4j.properties file in /usr/lpp/netview/v5r1/jars/logs can be modified to change the maximum size of these logs. Modify the value specified on the MaxFileSize statement in the properties file if you want to change the log size.
If you want to increase the number of saved log files, modify the value specified on the MaxBackupIndex statement.
NetView includes a non-supported application that translates native 3270 panels into HTML and displays them in the web browser. You can enable this application by adding it to the web portfolio. For details and help for the application, see the online help file FKXY3270.HTML. This file can be found in the usr/lpp/netview/v5r1/www/webapps/netview directory.
The NetView Web application and the Integrated TCP/IP Services Component utilize certain similar components. If both the NetView Web application services and the Integrated TCP/IP Services Component are to be active on the same Linux for zSeries LPAR, the jetty component of one of these must be configured to use a unique port number.
If the NetView Web application is to be modified, edit the file /usr/lpp/netview/v5r1/www/conf/jetty.xml.
If the Integrated TCP/IP Services Component is to be modified, edit the file /usr/OV/www/conf/jetty.xml.
In either file, look for the line:
<Set name="Port">8080</Set>
And change the port number from 8080 to a unique number (for example 8081) for that machine.
Operating System Environment Information
For AIX 4.3.3, the Recommended Maintenance Level is 09. This maintenance package is intended for customers who already have AIX 4.3.3 installed. The AIX 4330-09 maintenance package can be downloaded from http://techsupport.services.ibm.com/rs6000/fixes/, using APAR number IY22024. If you are a licensee of AIX 4.3.3, you can obtain an Update CD by contacting your point of sale and requesting feature code 0838.
For AIX 5.1, the Recommended Maintenance Level is 01. This maintenance package is intended for customers who already have AIX 5.1.0 installed. The AIX 5100-01 maintenance package can be downloaded from http://techsupport.services.ibm.com/rs6000/fixes/, using APAR number IY21957. If you are a licensee of AIX 5.1, you can obtain an Update CD by contacting your point of sale.
Note: Before updating your AIX 5.1.0 system to the AIX 5100-01 maintenance level, you must first apply and commit APAR IY19375 (which includes bos.mp64 5.1.0.1, bos.mp 5.1.0.1, and bos.up 5.1.0.1). Run smitty update
and pick IY19375 to install. When the installation completes you must reboot your system. After the system has rebooted, you can then install the AIX 5100-01 maintenance level. After the maintenance level has been installed, you must again reboot. See the AIX 5L for POWER Version 5.1 Release Notes for more information. APAR IY19375 can be obtained from the AIX Electronic Fix Distribution site: http://techsupport.services.ibm.com/rs6000/fixes/.
If you are using one of the supported non-UTF8 CKJ locales, the following fileset (available on both AIX 4.3.3 and AIX 5.1 base CDs) is required:
For Japanese users, if you are using Japanese Input Method, you may apply the following PTFs to avoid some Input Method related problems.
We refer to Linux on zSeries as zLinux. In the context of NetView Web application product, zLinux can generically refer to either SuSE Linux Enterprise Server for S/390 version 7.0 which is a SuSE 7.0 source base or SuSE Linux Enterprise Server 7 for S/390 and zSeries which is a 7.2 source base. Specifically, the formers abbreviated title is 31-bit SLES 7.0 or just SLES 7.0 while the latter is referred to as 31-bit SLES 7 or just SLES 7.
If you are using the Netscape browser on the AIX platform, and you launch the MIB Browser or Real Time Poller applet, a message is displayed stating that you are not authenticated. This problem occurs when using cookies to manage session tracking. The problem exists in the Java plugin, and a permanent fix will be available in the near future. A temporary workaround is to use URL re-writing for session tracking. See the NetView for z/OS Security Reference for more information on authenticating access to NetView by a web browser and session tracking.
When using the "Save as" feature with the utility, there are some problems that are 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.
This problem occurs during both English and Japanese installs on AIX 5.1 and 4.3.3.As you move forward during install, selecting each InstallShield panel, a warning message is displayed on the terminal session:
Warning: 2054-901
Name: scrollbar
Class: XmScrollBar
2054-448 The scrollbar page increment is less than 1.
This anomaly will not affect the installation of any of the features you select to install. You can ignore these warning messages.
The initial InstallShield panel (Splash panel) that displays the product title will appear blank when attempting to install on AIX with Japanese locale ja_JP. This problem does not affect the rest of the installation. All of the subsequent panels will be displayed correctly.
English characters are being displayed at the terminal session during the beginning of the AIX install for locale ja_JP only. These characters can be ignored. The installation process is not affected.
During AIX Japanese installation, one of the InstallShield panels displays only part of each pushbutton. Resizing the panel will properly display these pushbuttons so you can continue with the installation process. This occurs with ja_JP and Ja_JP locales.
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.
Text in the title field of the Netscape browser may be truncated horizontally using the Japanese version of NetView Web application on AIX. A display resolution of 1024x768 is recommended.
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.
