Hi,

Silly me, the whole feature exists in RHQ/JON. And as far as I can tell, it's even available in the UI, GroupOperationSchedulesDetailView.

GroupOperationSchedule has:

setHaltOnFailure(boolean) where you can set it to fail.

setExecutionOrder():

* The order to execute the operations - the first resource in the list is the first one to get its operation * invoked. If this is <code>null</code>, all operations can be invoked in any order and may even be done * concurrently.

So if you use setExecutionOrder() & setHaltOnFailure() with the GroupOperationSchedule before passing it to the ScheduleManager, you have the feature you requested.

Hi,

While you can't find this out of the box in the UI of RHQ/JON, this is easily doable with the RHQ-CLI interface. If you take a look at the samples directory and deploy-to-restart-JBAS.js (or jbossas.js), you can find function function _restartAS7(group) which uses _runOperationSequentially(group, operationName, operationConfig) method. This restarts in sequential order all the AS instances and waits for up to 60 seconds.

To modify the behavior to do one instance at a time and wait for it to finish and abort if it fails, create a loop around the group object (to find single instance ids) in the _runOperationSequantially, change GroupOperation to single reosurce operation and keep rest of the process intact. That should do all the things you need.

So using either of those scripts as a base provides you the functionality you're looking for. While it's not currently modified to work with Wildfly, that one also is quite simple to add (the resource names / groups are the only things that should need changing).

Hi all~,

Is there the feature to provide timegap between ripple restart of WildFly(JBoss EAP) cluster in Hawkular? If there is no feature, I'm curious there is a roadmap for this feature. Actually, this kind of feature is useful in a production environment.

I've already checked RHQ(JON) however there is no for ripple restart. RHQ(JON) provides below in restart operation page of Group menu. 1. "Execute: in the order specified below 2. "Halt on Failure?"

Thanks in advance.
