Configure foreign cell name bindings to enable your applications
to access other applications in other cells. A foreign cell is
a cell other than the one in which an application resides. A foreign
cell name binding is a context binding that resolves to the Cell Root
context of a foreign cell. All applications in the local cell can
look up objects in the foreign cell through the foreign cell binding.
Before you begin
Configure server clusters for failover support as needed.
Migrate
any Version 5.x or 6.0.x bootstrap addresses to use Version 6.1 or
later foreign cell bindings. Version 6.1 or later foreign cell bindings
enable you to specify more than one bootstrap address and enhance
failover support.
About this task
If applications in the local cell access applications in
one or more foreign cells, configure a foreign cell binding for each
foreign cell.
Administrators typically configure a foreign cell
binding before they configure any applications with Java™ Naming
and Directory Interface (JNDI) names that resolve through the binding.
However, you can create a foreign cell binding any time before you
start an application that uses the binding.
The foreign cell
and the local cell must have different names.
To view or configure
a foreign cell binding, use the administrative console.
Procedure
- Go to the Foreign cell
bindings page.
In the administrative console,
click .
- Create a new foreign cell binding.
- Open the New Foreign Cell Binding wizard.
On
the Foreign cell bindings page,
click New.
- On the Specify
foreign cell name panel, specify the name of the
cell that applications in the local cell will access.
- On the Specify
bootstrap addresses panel, specify a host name
and port for a new bootstrap address, and then click Apply.
Repeat this step for each bootstrap address that you need.
The name of each new bootstrap address is displayed in
the collection table on the Bootstrap
addresses page.
- On the Summary panel, verify
the settings and click Finish.
The name of the new binding is displayed in the collection
table on the Foreign Cell Bindings page.
- Optional: Edit a previously created foreign
cell binding.
- From the collection table on the Foreign cell bindings page, click
the name of the binding that you want to edit.
- On the foreign
cell binding settings page, edit the foreign cell name as desired.
- Edit the list of bootstrap addresses used for the foreign
cell binding.
- From the collection table on the Foreign
cell bindings page, click .
- On the foreign cell binding settings page, click Bootstrap
addresses. The Bootstrap
addresses page opens.
To add a new bootstrap address, click New and
specify the host and port.
To delete a bootstrap address, click
the check box next to the cell name and click Delete.
To
edit an existing bootstrap address, click the address you want to
edit. On the bootstrap
address settings page, edit the host and port as desired and
click OK to register the change.
Results
Configurations for foreign cell bindings are created or changed
