Virtual database shutdown without recovery log causes MBean unregister error
----------------------------------------------------------------------------
Key: SEQUOIA-867
URL: https://forge.continuent.org/jira/browse/SEQUOIA-867
Project: Sequoia
Type: Bug
Components: Core
Versions: Sequoia 3.0 beta1, Sequoia 2.10.2
Reporter: Emmanuel Cecchet
Assigned to: Emmanuel Cecchet
Fix For: Sequoia 3.0 beta 2
Reported by Waseem Taj <[EMAIL PROTECTED]> on the Sequoia mailing list:
We have a web based application running on tomcat (5.5.9). It uses hibernate
(3.0), MySQL database (4.10) and MySQL J/connector(5.0.4) for database
connectivity.
Currently we are investigating Sequoia to provide load balancing and
transparent failover features.
We have a controller with RAIDb-1 configuration with just one database
backend.When we shutdown the controller via console, we are getting the
following error:
" ERROR controller.virtualdatabase.db Failed to unregister the mbean of virtual
database db
javax.management.InstanceNotFoundException:
sequoia:type=VirtualDataBase.RecoveryLog,VirtualDataBase=db".
See the end of the email for detail error log. What can I do to fix this error?
Also we do not need to use the RecoveryLog (as we are using Mysql replication),
how do I get rid of the error message:
"ERROR controller.jmx.MBeanServer Register mbean of type
sequoia:VirtualDataBase=db,type=VirtualDataBase.RecoveryLog failed with error
sequoia:type=VirtualDataBase.RecoveryLog,VirtualDataBase=db ({2})"
Thanks for your help in advance.
