Application architecture and Precise for Web configuration

When using Apache 2.0 and higher, or IIS, as a proxy to J2EE application servers, it is recommended to install client-side and server-side on the proxy tier and not on the J2EE application server. If you need to install Precise for Web on the J2EE application server, only install the server-side and not client-side collection on the J2EE tier.

Installing a Web cluster

This section describes the procedures that are needed to install a Web cluster. A Web cluster is defined as a set of WebLogic or WebSphere JVMs that share the same configuration and are started from a shared location. Installing a Web cluster has two parts. The first one, described below, consists of creating a repository for the cluster configuration based on the definition of any of the cluster's JVM and performing the action items on the shared location. Once the action items are performed and JVMs are restarted, the second part of the installation takes place and each JVM instance is installed automatically and Precise starts to monitor it.

When the Web Tier Collectors have been installed, post-installation action items may be required. There might be additional action items not listed below, that are required in each installation. Upon finishing your installation, verify that all action items have been completed by checking the list generated on the Action Items screen.

Post-installation tasks for WebLogic, WebSphere, Tomcat, and Sun One (J2EE stack)

To monitor the application(s), you need to register the Precise for Web agent(s) as Web application filters. This section describes how to add Precise for Web technology to the Web application(s) Web descriptor files.

...

• (Best practice) To add this script to you application redeployment script, so it will be done automatically.

• Change the central application file (if the application is clustered and there is a central location as opposed to a local location). This way the Precise filters will stay in the application in each redeployment.

  Info
  If you do so, you will need to redeploy the application instead of performing a mere JVM restart.

  Info
  If you are installing Precise for Web on a cluster (WebLogic or WebSphere) the option to change the central application file is the only option.

• Examples of application locations:
  
  • The WebLogic 10.3 console shows the .EAR file location under “deployments”. Then click on your application name to see the path.
  • The WebSphere 6.1 console displays the names of .EAR files, but not their location. The typical location of and .EAR file is:
    <install-dir>\profiles\[profile-name]\config\cells\[cell-name]\applications\PlantsByWebSphere.ear\PlantsByWebSphere.ear
  • For Tomcat 5.x & 6.x: <tomcat-dir>\webapps\<app-name>\web-inf\web.xml
  • For Sun One 6.x: <sunone-dir>\WebServer6.1\<domain-name>\webappsWeb.xml appears inside each application.

Modifying the Web descriptor file on a Web application with multiple instances

When installing a Web application with multiple instances, running the psww_web_desc_modify command will create multiple EAR files, with each EAR file containing a different instanceId and i3root value, corresponding to the instances in the Web application.

...

1. Run the web desc modifier without the -instanceId and -i3root parameters.
2. Add the following parameters to the JVM command line:
   • -DPssInstanceID=<instance_ID>
   • -DPssI3Root=<precise_root>

Adding Precise for Web filter(s) to the Web server classpath

To monitor the application, the Precise for Web agent(s) jar(s) must be loaded. Consult with your Web Administrator on where the right location is to do so. Examples:

...

1. Open WebSphere admin console (URL: ibm/console/login.do).
2. In the Integrated Solutions Console, click the Monitoring and Tuning tab.
3. From the drop-down menu, click on Performance Monitoring Infrastructure (PMI).
4. On the right pane, select the server upon which you want to enable statistics (for example, server1.)
5. In the next screen, click the Runtime tab.
6. On the Runtime tab, select either:
   • Basic
   • Extended
   • All

   • Custom

     Info
