JDBC exception when sending and receiving a lot of messages (MySQL 5 in use for
persistence)
--------------------------------------------------------------------------------------------
Key: AMQ-1870
URL: https://issues.apache.org/activemq/browse/AMQ-1870
Project: ActiveMQ
Issue Type: Bug
Components: JMS client
Environment: Active MQ 5.1, Windows XP, MySQL 5.0.45, MySQL
Connector/J 5.1.5
Reporter: PJ Fanning
Fix For: 5.1.0
The number of messages that were on the queue was approx 3 million when this
exception happened. Would it be possible to modify the code so that the
setMaxRows value is kept to a much lower number?
java.sql.SQLException: setMaxRows() out of range. 50871918 > 50000000.
