Hello again, at the moment I am analysing and evaluating the different Active MQ HA possibilities.
At the Active MQ instance level I found * Shared Nothing Master/Slave > two separate instances * Shared Database Master/Slave > two instances, active-passive, sharing the same database * Shared File System Master/Slave > two instances, active-passive, sharing the same filesystem At the Active MQ client config level I found * failover protocol At the moment I favor using Shared Database Master/Slave using an Oracle RAC DB to eliminate the single point of failure on the message persistence layer. Under http://activemq.apache.org/jdbc-support.html Oracle DB is listed as supported database. Do you know - which versions are supported? - is a RAC failover transparent to the Active MQ instance? - how is the message persisted in Oracle DB? As BLOB? Can I configure the persistence (i.e. to SQL query by Message Id)? - which database is best supported? - how big is performance impact, if I locate Master, Slave and Oracle DB on different systems compared to a single broker instance using local file system? - Is special configuration of the broker instance needed due to the increased latency? - Is Shared Database faster than Shared Filesystem? Thanks for any help! -- View this message in context: http://activemq.2283324.n4.nabble.com/Choosing-the-right-HA-option-tp4383112p4383112.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
