    Multiple Release Co-existence Support

    IBM Parallel Environment Runtime Edition for AIX 1.1.0.9 (PTF9) and earlier levels do not support the infrastructure for multiple release level coexistence, when PE 1.2 is also installed. If customers want to install both PE 1.1 and PE 1.2 on the system, it is recommended that PE 1.1.0.10 (or later) is installed, plus PE 1.2.0.2 (or later), is required.

    PE 1.1.0.10 (or later) and PE 1.2.0.2 (or later) are required to coexist and switch back and forth between PE 1.1 and PE 1.2 for rolling upgrade support.

    PE 1.2 and PE 1.1.0.10 introduces a new directory structure that simplifies the symbolic links that PE Runtime Edition creates and maintains. The 'pelinks' script has been updated in these levels of PE. As a result, customers wanting to do a "rolling upgrade" (upgrading subsections of the cluster with newer levels of software) must install PE 1.1.0.10 (or later) as the default level on all nodes. This will enable multiple PTF and release levels to coexist, and provides the ability to uninstall cleanly.

    If the whole cluster is not updated with the same levels of PE on all the nodes, then the scheduler should be used to create resource pools to separate the nodes.

Installation information

  • - Installing a PE update for AIX
    1. Download a PPE RTE for AIX update package into any directory on your system.
    2. Unzip and extract the BFF image(s) from the *.tar.gz file.
    3. Install the PPE RTE updates on your system using the smit update_all command.
