Using UTF-8 encoding

2010-04-21
QueueMetrics is a fully internationalized application: that is, it handles all user transaction with UTF-8 encodig, and therefore can display and accept any character for any language.

Unfortunately, MySQL does not natively use UTF-8 encoding for its tables and will try to use the "current encoding" whenever possible. So you may notice that if you e.g. enter an agent's name using not-Latin characters, when you read it back from disk it appears all garbled or a series of ??? signs.

To make QM fully able to process UTF-8 strings, you should follow the steps detailed here:

1. Run the following commands on all tables of the database but the queue_log table:
ALTER TABLE `agaw_alarms` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `agaw_dati` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `agaw_logs` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `agaw_runs` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `agenti_noti` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `arch_classes` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `arch_syslog` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `arch_users` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `broadcast_msg` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `call_status` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `code_possibili` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `dbversion` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `locations` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `oq_calls` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `oq_notes` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `oq_queues` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `pause_codes` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `qa_data` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `qa_forms` CONVERT TO CHARACTER SET utf8;
ALTER TABLE `qa_forms_items` CONVERT TO CHARACTER SET utf8;



If your system has other tables, please do the conversion on ALL tables.

2. Open the QueueMetrics web.xml and modify the connection string adding, before the </param-value> tag, the string:
&amp;useUnicode=true&amp;characterEncoding=utf8&amp;characterSetResults=utf8
After this modification you should have something that looks like:
<param-value>jdbc:mysql://127.0.0.1/queuemetrics?zeroDateTimeBehavior=convertToNull &amp;jdbcCompliantTruncation=false&amp;user=queuemetrics&amp;password=javadude &amp;useUnicode=true&amp;characterEncoding=utf8&amp;characterSetResults=utf8</param-value>


It must all be written on a single line.

3. Then download the latest MySQL java connector binary package you can find at the link:http://dev.mysql.com/downloads/connector/j/5.1.html
Extract the mysql-connector-java-5.1.7-bin.jar file and copy it on your QueueMetrics box, placing in the folder /usr/share/java.
Replace the symbolic link you can find in /usr/local/queuemetrics/webapps/queuemetrics-1.x.x/WEB-INF/lib in order to have it pointing to new connector.

4. Restart the QueueMetrics service issuing a /etc/init.d/queuemetrics restart

This will enable UTF8 support.
