Install WebSphere Commerce interim fixes
Each WebSphere Commerce interim fix (ifix) contains fixes for one or more APARs.
Each WebSphere Commerce interim fix package contains a readme file, which contains instructions for installing the interim fix.
When you install an interim fix, ensure that the custom assets are properly deployed. If the interim fix applies to one of the WebSphere Commerce EAR files (Commerce EAR, Payments EAR, or Social Commerce EAR) then the install will deploy the fixes using standard WebSphere Application Server deployment tools.
- Use the roll out update process for installing interim fixes
Roll out update is a means to achieve high availability when applying interim fixes to the WebSphere Commerce application which is deployed to a clustered environment. Not all nodes in the cluster need to be shut down during the process. The deployment manager chooses one node and stops the server only on that specific node. After synchronizing the updates for the node, the server is started again. The process is repeated for each node in the cluster.
