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. |
