What to do next
Use the Application Manager deployment to verify that SSL is functioning between Application Manager and
the Connector. If an SSL problem exists, when you use the Connector Web interface and provide the activation
code, the Connector displays an error message indicating that the Connector cannot connect to a specified
URL.
Configuring Clustering for Application Manager
To configure Application Manager instances in a cluster, you must connect each Application Manager instance
to a shared external database server.
By default, Application Manager uses its internal database server. You can use the internal database server if
you deploy a single Application Manager instance. However, if you use multiple Application Manager
instances you must use an external database server and point each Application Manager instance to that
external database server.
Application Manager employs encryption to secure the Application Manager data. The Application Manager
instances in your deployment must all have a copy of the same master key. When you first configure an
Application Manager instance, a new master key is generated automatically and stored in the master keystore
of that Application Manager instance. You can then add additional Application Manager instances to the
cluster. However, in order to access the encrypted data of the shared database server, each Application
Manager instance in the cluster must have a copy of the same master key.
To ensure that each Application Manager instance has a copy of the same master key, you can perform one of
two procedures.
Table 7-3. Methods for Copying a Master Key Among Application Manager Instances
Clone an Existing Application Manager Instance
Configure a New Application Manager Instance and
Fetch an Existing Master Keystore
This method is simpler and less prone to error. After you
have configured an Application Manager instance, you use
the Application Manager virtual appliance Interface to
configure a connection to an external database server, which
disables the internal database and creates a master key.
To create additional Application Manager instances, you can
clone a previously configured Application Manager virtual
appliance. The cloned Application Manager instance
matches the original. Therefore, it is configured with a copy
of the master key and it is connected to the external database.
IMPORTANT After you clone a virtual machine, you must
assign the cloned virtual machine a new IP address and
hostname. Other actions might be required. Search
http://kb.vmware.com/kb/ for related VMware Knowledge
Base articles.
If you do not clone a previously configured Application
Manager virtual appliance, you must install and configure a
new Application Manager instance to point to the same
external database server as the first Application Manager
instance. Then you must fetch the master keystore from a
previously created Application Manager instance. This
action copies the master key to the current Application
Manager instance, allowing that instance to read the
encrypted data in the external database. For each Application
Manager instance you add to the cluster, you must fetch the
master keystore from a previous instance.
Configure an External Database Connection
To configure clustering for Application Manager, for each Application Manager instance, you must connect
the Application Manager instance to an external database server. You can then add additional Application
Manager instances to the deployment.
The action of configuring a connection from an Application Manager instance to an external database server
automatically disables the internal database server. You must configure an external database connection for
the first Application Manager instance that you connect to the external database server.
NOTE If you make a clone of a previously configured Application Manager instance, the cloned Application
Manager instance automatically connects to the external database server. You do not need to configure an
external database connection for the additional instance.
