Allow the setting of an initial delay in PeriodRecovery ------------------------------------------------------- Key: JBTM-2632 URL: https://issues.jboss.org/browse/JBTM-2632 Project: JBoss Transaction Manager Issue Type: Enhancement Components: Recovery Reporter: Matthew Robson Assignee: Tom Jenkinson Fix For: 5.next Currently Periodic Recovery kicks off at the same interval on every server. As a domain mode cluster grows in size, this leads to significant contention in the DB, especially for RAC implementations. Completion time goes from milliseconds with 1 server to 20+ seconds with 20+ servers. In an effort to avoid this, an offset the initial start of Periodic Recovery could be provided for the nodes in the cluster. Periodic Recovery currently leverages 2 properties: <system-properties> <property name="RecoveryEnvironmentBean.periodicRecoveryPeriod" value="120"/> <property name="RecoveryEnvironmentBean.recoveryBackoffPeriod" value="10"/> </system-properties> The proposal would be to add a 3rd property, 'RecoveryEnvironmentBean.periodicRecoveryInitilizationOffset' which, when set, would be used for each node. If not set, it would default to current behavior.
