[jboss-jira] [JBoss JIRA] (JGRP-1543) RELAY2: provide SITE-UNREACHABLE notifications
[
https://issues.jboss.org/browse/JGRP-1543?page=com.atlassian.jira.plugin....
]
Bela Ban commented on JGRP-1543:
--------------------------------
RELAY2 on the *original sender* of a message to an unreachable site X gets an event
SITE_UNREACHABLE sent up the stack. This can be caught in a JChannel setting an UpHandler,
or using an RpcDispatcher by creating a subclass and overriding handleUpEvent().
The latter case is relevant for Infinispan: CommandAwareRpcDispatcher extends
RpcDispatcher and it should now override handleUpEvent():
{code}
protected Object handleUpEvent(Event evt) {
switch(evt.getType) {
case Event.SITE_UNREACHABLE:
SiteMaster unreachable_sm=(SiteMaster)evt.getArg();
short site=unreachable_sm.getSite();
String site_name=SiteUUID.getSiteName(site); // "SFO"
// do something with the site
break;
}
return super.handleUpEvent();
}
{code}
RELAY2: provide SITE-UNREACHABLE notifications
----------------------------------------------
Key: JGRP-1543
URL: https://issues.jboss.org/browse/JGRP-1543
Project: JGroups
Issue Type: Feature Request
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 3.2.3, 3.3
Provide notifications when a site is down, every time a message is sent to a
SiterMaster(X) and X is down, a notification SITE-UNREACHABLE should be emitted.
This can be:
- A SITE_UNREACHABLE event being sent up the stack of the message sender
- A callback being invoked on registered listeners in RELAY2
