Automatic message recovery in the BPEL Service Engine
The next logical thing for you to do as an administrator would be to automate the
fault recovery process. The BPEL Engine has some auto-recovery features that
are buried in an MBean property allowing recovery of messages either at the
time of restarting the SOA server or scheduling a recovery during off-peak hours.
Messages being recovered can be throttled by limiting the number of messages
picked up on each run. The
RecoveryConfig
configuration dashboard in
Sys-
tem MBean Browser
along with the property settings to schedule automatic re-
covery is shown in the next screenshot and the steps to configure the MBean
are as follows:
1.
Log in to Oracle Enterprise Manager Fusion Middleware Control.

MBean.

The
RecurringScheduleConfig
MBean allows configuring a time window,
preferably non-peak production hours, wherein automatic recovery through
retry can be scheduled. The
maxMessageRaiseSize
property controls the
number of messages recovered in one go.
5.
StartupScheduleConfig
on the other hand instructs the engine to recover
faulted messages on server startup. The amount of time allocated by the en-
gine for recovery is determined by the
startupRecoveryDuration
property.
However, it is not always possible to recover everything automatically. Auto-re-
covery is subject to some conditions. Consider the following two scenarios:
