[wsas-java-dev] [jira] Assigned: (WSAS-625) data service hotupdate does not handle re-established db connections

Afkham Azeez reassigned WSAS-625:
---------------------------------

    Assignee: sumedha rubasinghe  (was: Afkham Azeez)

Here is how this should be fixed.

The dataservice deployer detects that the DB connection is unavailable.
Now it registers a TimerTask which periodically tries to connect to the DB
If successful, it removes the service from the faulty list, redeploys the service

Similarly, even if the service was successfully deployed, the DB connection can fail later. In this case, when a DB failure is detected, the service should be classified as a faulty services, and a TimerTask should try to re-establish the connection.
