All, Currently I am looking into this type pf deployment to provide HA application. After couple of weeks of investigation I came up with a theory of how the deployment model would be. Before I go ahead and go on in my project, I would like to get your feedback on that matter (real experiance is far better than theories :-) )
- Database The plan is to use clustred MySQL with x no of nodes (blades) - AS Jboss 4.03 + ejb3, running in a clustred deployment on y number of nodes (blades) All the AS are conntectd to the same MySQL cluster Questions: - First. Is this deployment configuration possible? - To address the clusterd MySQL, I have to specify "," seprated host/port in the uri. Will jboss accept this in the -ds.xml? - In case of a filure in the active MySQL, MySQL will throw exception (switch over is not 100% transparent)... will this exception be treated as other "Transaction-Retry" exception? - (I know the answer of this one but I will ask it to be on the safe side) In case of datbase lock time-out, will the AS retry the transaction (ex. call my stateless session bean method AGAIN) - As a part of the appliction I have in-band JCA (converts socket requests into JMS to be processed later on by MDB), how can I make this part of the application HA ??? - MDB can be deployed in clustred mode but how can I make the JMS queue itself HA? Thanks in advance for your help Hamdy View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3915764#3915764 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3915764 ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
