[jira] Created: (FELIX-1752) [Karaf] Extend DefaultJDBCLock to
support MySQL out of the box.
[Karaf] Extend DefaultJDBCLock to support MySQL out of the box.
---------------------------------------------------------------
Key: FELIX-1752
URL: https://issues.apache.org/jira/browse/FELIX-1752
Project: Felix
Issue Type: Improvement
Components: Karaf
Reporter: Jamie goodyear
Fix For: karaf-1.0.2
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.

[jira] Updated: (FELIX-1752) [Karaf] Extend DefaultJDBCLock to
support MySQL out of the box.

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).
