IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Native 64 bit versions of IBM Tivoli Monitoring distributed infrastructure
IBM Tivoli Monitoring V6.3 offers native 64 bit versions of IBM Tivoli Monitoring infrastructure components for Windows, Linux on AMD64 and Intel EMT (x64), Linux on System z, and AIX systems.
On 64 bit systems, it is recommended to install components from the 64 bit version of the installation image. However, you can install components from the 32 bit installation image on 64 bit systems. On 32 bit systems, you can only install components from the 32 bit installation image.
The following conditions apply to upgrading the Tivoli Enterprise Monitoring Server and Tivoli Enterprise Portal Server:
- Automatically upgrading the Tivoli Enterprise Portal Server from 32 bit to 64 bit or from 64 bit to 32 bit is not permitted. For instructions on performing this conversion, see Upgrade a 32 bit portal server to 64 bit or Upgrade a 32 bit Windows portal server to a new system running 64 bit Windows.
- Upgrade the Tivoli Enterprise Monitoring Server from 64 bit to 32 bit is not permitted.
- Automatically upgrading the Tivoli Enterprise Monitoring Server from 32 bit to 64 bit is permitted.
Certain OMEGAMON agents are designed to run as shared libraries that load into the Tivoli Enterprise Monitoring Server process address space. These agents might not continue to function after you have upgraded the Tivoli Enterprise Monitoring Server from 32 bit to 64 bit on your system. The IBM Tivoli Monitoring installer will recognize this condition on your system and warn you of the possible problem.
If a bit version conflict is detected during the upgrade process, an error message is displayed identifying both the component and the conflict. The Tivoli Enterprise Portal Server, Tivoli Enterprise Monitoring Server, or both, are removed from the list of available features.
If you are upgrading all 32 bit components to IBM Tivoli Monitoring V6.3, and also want to upgrade a 32 bit Tivoli Enterprise Monitoring Server to a 64 bit version, upgrade the components in the following order:
- Use the 32 bit IBM Tivoli Monitoring installation image to upgrade the Tivoli Enterprise Portal Server first (and 32 bit agents if required).
- Use the 64 bit IBM Tivoli Monitoring installation image to upgrade the Tivoli Enterprise Monitoring Server to the 64 bit version (and 64 bit agents if required).
