Examples of com.arjuna.ats.arjuna.recovery.RecoveryModule

com.arjuna.ats.arjuna.recovery.RecoveryModule
Interface for Recovery manager plug-in module. RecoveryModules are registered via the properties mechanisms. The periodicWorkFirstPass of each module is called, then RecoveryManager waits for the time interval RECOVERY_BACKOFF_PERIOD (seconds), then the periodicWorkSecondPass of each module are called. The RecoveryManager then waits for period PERIODIC_RECOVERY_PERIOD (seconds) before starting the first pass again The backoff period between the first and second pass is intended to allow transactions that were in-flight during the first pass to be completed normally, without requiring the status of each one to be checked. The recovery period will typically be appreciably longer.
