> Key: AMQ-3304
> URL: https://issues.apache.org/jira/browse/AMQ-3304
> Project: ActiveMQ
> Issue Type: Improvement
> Components: Documentation
> Affects Versions: 5.5.0
> Reporter: Arnaud BRAND
> Priority: Minor
>
> When using the JDBCPersistenceAdapter with SQLServer the use of the lockDataSource property is mandatory, or else the transaction log will fill up (wether the db is in simple or full recovery mode doesn't change anything), and the broker will eventually crash.
> The page http://activemq.apache.org/sqlserver.html should clearly state that the lockDataSource should be used and should point to another database.
> Additionnaly, this page could give another configuration tweak for SQLServer which results in a sensible performance improvement when queues are quite full (>50000 messages in our configuration):
> {code:xml}
> <statements>
> <statements findNextMessagesStatement="SELECT TOP 5 ID, MSG FROM ACTIVEMQ_MSGS WHERE CONTAINER=? AND ID > ? ORDER BY ID"/>
> </statements>
> {code}
