Upload an appliance patch

By uploading an appliance patch, you can upgrade to the newest version of the CIOS and access the latest features.

Before you begin

Important: If you use SAP projects, you must ensure that you install the SAP 64-bit libraries. Remove any SAP 32-bit libraries before you upgrade to App Connect Hypervisor Edition. If there are any SAP 32-bit libraries that are installed, you cannot upgrade to App Connect Hypervisor Edition.

Before you upgrade, it is a good practice to make a snapshot of the current VM. Upgrade wipes out any manual modification of any script files. If applicable, engage IBM Support to reconfigure those settings after upgrade.

Memory allocation for 32GB VM in V7.5.3 is 16GB/4GB/4GB, for 16GB, 4GB/3GB/4GB on Maestro/WMC/Derby process. Before you upgrade, run command debug meminfo to keep record of current allocation. The -Xmx value in Heap ALLOCATION section indicates current memory distribution among the processes. Determine rebalance is needed after upgrade, and engage IBM Support if necessary.

About this task

Use the Web Management Console (WMC) to upgrade to the latest version of CIOS by uploading an upgrade image onto the appliance. This upgrade process only replaces or adds necessary files, it does not destroy any data. Note, the WMC forces any running projects to be undeployed and stops any active orchestration jobs currently running on the appliance during the upgrade procedure. After the appliance is upgraded, you cannot undo or roll back to the previous version.
Note: Upgrades can also be applied through the Command Line Interface (CLI). For more information, see the system update command in the CLI Reference Guide.

Procedure

  1. Download the App Connect Hypervisor firmware upgrade file (type = vcrypt2) from Fix Central: http://www.ibm.com/support/fixcentral/.
  2. Download the appliance upgrade image file to a location you can access from your Windows workstation, for example: C:\Desktop.
  3. Use the WMC to log into the appliance that is running the CIOS.
  4. In the WMC, select System > Upgrade.
  5. Click Upgrade operating system. The Upgrade Operating System panel is displayed.
  6. In the text field, either specify the path to the appliance upgrade image file or browse to locate the appliance upgrade image file.
  7. Click Upgrade.

    The upgrade file is uploaded. The Upgrade Operating System panel displays: "Uploading file..."

    When the file has uploaded, the Upgrade Operating System panel displays: "Upgrading operating system. please wait..."

    When the upgrade has completed, the Rebooting Appliance panel displays: "The appliance is rebooting. Please wait..."

    If a console window to the appliance is open, the rebooting messages are displayed.

  8. Use the WMC to log into the appliance. You might need to click the refresh button of the browser.

What to do next

Using the WMC, redeploy any projects that were undeployed by this upgrade procedure. Upgrade to a Studio version compatible with the installed CIOS. For more information about appliance and Studio compatibility, see the Compatibility section of the CIOS Release Notes® or the App Connect Studio Release Notes. For the procedure on upgrading Studio, see Installing Studio.
