> 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.

[JBoss JIRA] (JBTM-2719) tpcall get three seconds delay in the fooapp quickstart

> Project: JBoss Transaction Manager
> Issue Type: Bug
> Components: BlackTie, Demonstrator
> Reporter: Amos Feng
> Assignee: Amos Feng
> Fix For: 5.next
>
>
> The apr_pollset_poll in HybridSocketEndpointQueue.cxx Line 392 is blocking and timing out after 3 second. It is the root cause for the tpcall delaying.
> So it should try to wake up the polling in non-conversation session while disconnect
