Applying an emergency fix to a virtual application instance

Interim fixes are applied to virtual application instances as emergency fixes. Apply emergency fixes to your IBM® Business Process Manager virtual application instances that are running in your cloud.

Before you begin

For service to be scheduled or applied, ensure that the following prerequisites are met:

You have all access to the virtual application instance or the Appliance administration role with Full permissions.
The virtual application instance is started.
The emergency fix is added to the catalog.

Attention:

Create a backup before you apply an emergency fix. IBM PureApplication® System does not capture a snapshot when you apply an emergency fix to a virtual application instance.
The virtual application instance is unavailable while emergency fixes are being installed because IBM BPM runtime instances are restarted during the process.

About this task

When you add an emergency fix, you define the pattern types that the fix applies to. When you schedule a service request, the list of available fixes contains the fixes that are applicable to the pattern type that is used to create your virtual application instance.

Procedure

To apply an emergency fix, complete the following steps from the Virtual Application Instances window:

Select the virtual application instance that you want to apply the fix to.
Click Maintain to put the virtual application instance in maintenance mode.
Optional: Schedule a service request. By default, the fix is applied immediately. To schedule it to be applied later, click Schedule service and provide the necessary information.
Click Manage to open the Virtual Application Console window.
Click the Operations tab.
From the left panel of the Operations page, click the BPM_MAINTAINANCE operation.
From the Maintain Business Process Manager Instance section in the right panel, click Select beneath the Interim fixes URL field and select the emergency fix.
Click Submit.
After the emergency fix is successfully applied, click Maintenance mode to turn off maintenance mode.

Results

Important: If you apply a fix to a virtual application instance and then scale out custom nodes in that virtual application instance, the new custom nodes also contain the fix that you installed if the fix package remains on PureApplication System.
