IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1

Upgrade from ITCAM for Web Resources 6.2

ITCAM for Web Resources 6.2 monitors WebSphere application servers,. J2EE application servers, and HTTP Servers using IBM Tivoli Monitoring. You can upgrade all configurations of this product to ITCAM for Application Diagnostics 7.1.

An ITCAM for Web Resources 6.2 installation can include any of the following components:

To plan an upgrade from ITCAM for WebSphere 6.1 and ITCAM for J2EE 6.1 to ITCAM for Application Diagnostics 7.1 on Windows, Linux, and UNIX systems, determine the following information:

You must upgrade all the components that you are using. Before upgrading any of the other components, upgrade IBM Tivoli Monitoring to version 6.2.2 or later.

To upgrade monitoring for WebSphere servers:

  1. Upgrade IBM Tivoli Monitoring to version 6.2.2 or later. See IBM Tivoli Monitoring: Installation and Setup Guide.

  2. Install new support files for ITCAM Agent for WebSphere Applications 7.1 on the Tivoli Enterprise Monitoring Servers, on all Tivoli Enterprise Portal Servers, and on all Tivoli Enterprise Portal desktop clients. Monitoring with the older Tivoli Enterprise Monitoring Agents continues after this step.

  3. On all hosts where the WebSphere Tivoli Enterprise Monitoring Agent is installed, install ITCAM Agent for WebSphere Applications 7.1, using the same installation directory as the older Tivoli Enterprise Monitoring Agent. After installing version 7.1, immediately install version 7.1.0.1. This installation upgrades the monitoring agent to the new version. It communicates with the older data collectors if they were updated to 6.1 fix pack 4 or later; so, for such data collectors, monitoring is only interrupted briefly. However, for any data collectors that are not updated to 6.1 fix pack 4, Tivoli Monitoring stops at this point. Performance of the application servers is not affected. See IBM Tivoli Composite Application Manager: Agent for WebSphere Applications Installation Guide; follow the installation process described in the chapters on installing the agent on Windows or on Linux and UNIX systems, as appropriate.
  4. On all hosts where the ITCAM for WebSphere data collector is installed, install ITCAM Agent for WebSphere Applications 7.1. (Do not install it a second time if you have already installed it on the same host in Step 3). After installing version 7.1, immediately install version 7.1.0.1. This installation makes the new data collector available; however, all application server instances are still monitored by the old data collector at this point. See Agent for WebSphere Applications on Windows, Linux, and UNIX systems; follow the installation process described in the chapters on installing the agent on Windows or Linux and UNIX systems, as appropriate.

  5. Use ITCAM Agent for WebSphere Applications 7.1.0.1 configuration, upgrade the monitoring of each application server instance to the new data collector. For data collectors that were not updated to version 6.1 fix pack 4, this step is required to reenable Tivoli Monitoring. For version 6.1 fix pack 4 or later data collectors, monitoring is not interrupted, so you can perform the upgrade at a convenient time. The upgrade involves restarting the application server instance. See IBM Tivoli Composite Application Manager: Agent for WebSphere Applications Installation Guide; follow the upgrade procedure described in the chapters on configuring the agent on Windows or Linux and UNIX systems, as appropriate.

z/OS WebSphere monitoring can also be a part of an ITCAM for Web Resources installation. For the upgrade process for it, see Upgrade from ITCAM for WebSphere 6.1 on z/OS.

To upgrade monitoring for J2EE servers, update all ITCAM for J2EE Tivoli Enterprise Monitoring Servers, Tivoli Monitoring support files, and data collectors to the version that is part of ITCAM for Application Diagnostics 7.1. See ITCAM Agent for J2EE data collector Installation Guide and ITCAM Agent for J2EE Monitoring Agent Installation Guide.

If the Tivoli Enterprise Monitoring Agents and Tivoli Monitoring support files for J2EE support files are already updated to 6.2 fix pack 5 and the data collectors for J2EE are already updated to 6.1 fix pack 4 (also used for version 6.2), this step is not required because the version shipped with ITCAM for Application Diagnostics 7.1 is the same.

To upgrade monitoring for HTTP Servers (Web Servers):

  1. Install new support files for ITCAM Agent for HTTP Servers 7.1 on the Tivoli Enterprise Monitoring Servers, on all Tivoli Enterprise Portal Servers, and on all Tivoli Enterprise Portal desktop clients. Monitoring with the old Tivoli Enterprise Monitoring Agents continues after this step.
  2. On all hosts where the ITCAM for Web Resources Tivoli Enterprise Monitoring Agent for Web Servers is installed, install ITCAM Agent for HTTP Servers 7.1, using the same installation directory as the older Tivoli Enterprise Monitoring Agent. This installation upgrades the agent to the new version. You must restart the HTTP servers. Monitoring is not interrupted for any extended periods. See See ITCAM Agent for HTTP Servers Installation Guide.

ITCAM Agent for HTTP Servers 7.1 does not support Microsoft Internet Information Services (IIS). Do not upgrade any installations of ITCAM for Web Resources Tivoli Enterprise Monitoring Agent for Web Servers that monitor IIS. You can use these agents to monitor IIS and use ITCAM Agent for HTTP Servers 7.1 to monitor other HTTP servers in the same Tivoli Monitoring infrastructure, but typically not on the same host.
