Jamie goodyear updated FELIX-1752:
----------------------------------
Attachment: FELIX-1752.patch
File: FELIX-1752.patch
This patch introduces support for a MySQL database backend to Karaf locking
table.
Users of the MySQLJDBCLock would specify the following in their
system.properties file:
karaf.lock.class=org.apache.felix.karaf.main.MySQLJDBCLock
karaf.lock.jdbc.url=jdbc:mysql://address:port/dbname
karaf.lock.jdbc.driver=com.mysql.jdbc.Driver
Note:
A cleaner model for JDBC Lock support may be in order as additional database
support is added (similar to Apache ActiveMQ core JDBC Adaptors).
> [Karaf] Extend DefaultJDBCLock to support MySQL out of the box.

> This is to ensure that the DefaultJDBCLock implementation works with MySQL.
> The MySQL 'lock table' mechanism may be used to allow a master process to
> hold a locking table from slave instances. When the master instance losses
> connection with the DB the lock is broken allowing a slave instance to take
> over processing.
