Multiple instance support

Multiple instances of InfoSphere® MDM is supported by installing the application in a clustered environment.

All InfoSphere MDM application instances in the clustered nodes within a WebSphere® Application Server cell must be deployed with the same version of InfoSphere MDM product code and must have the same version of the InfoSphere MDM customization code.

If you want to use the same physical machine (or LPAR) to deploy a second InfoSphere MDM application instance that is running a different version of InfoSphere MDM product code, you must create a second WebSphere Application Server cell, deployment manager, and node profile.

If you want to configure a simple functional test environment, you can use the same WebSphere Application Server cell and node to deploy multiple instances of InfoSphere MDM with the same version of InfoSphere MDM product code and different version of the InfoSphere MDM customization code. However, some limitations do apply. Once you uninstall any one of InfoSphere MDM instances in the WebSphere Application Servercell, the other InfoSphere MDM instances are no longer functional. Do not attempt this configuration in a production environment.
