(7.0.z) JBTM-2720 - Allow the setting of an initial delay in PeriodRecovery

    XMLWordPrintable

    Details

      Description

      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.
