Availability of cell-scoped and cell persistent JNDI data when the Deployment Manager is not running
 Technote (troubleshooting)
 
Problem(Abstract)
What happens with cell-scoped and cell persistent JNDI data when the Deployment Manager is not running?
 
Resolving the problem
When a resource is defined in a cell scope, the resource will be bound under the server
root for all application servers within the cell. So even with the dmgr down, the lookup on such a resource should still be successful.

In the case of a name space configured binding under "cell/persistent", the lookup on this binding should also be successful without the dmgr running since every application servers has the copy of cell persistent partition.

When a dmgr is down, all read operations in the cell persistent partition will still succeed, but for any write operation to the cell persistent partition, the dmgr and all nodeAgent servers have to be running in order for such write operation to be succeed. Write operations occur when new persistent data is added, or when resources, such as starting EJBs, are made available to be used.
