Brand new management and monitoring capabilities using JMX were starting to be added to Derby in the first calendar quarter of 2008. This issue tracks efforts documenting this functionality.
A JMX M&M functional specification document (funcSpec.html) is attached to
DERBY-1387. More information may be available on the wiki - http://wiki.apache.org/db-derby/DerbyJMX - and in JMX-related Javadocs ("published API") (packages org.apache.derby.mbeans and org.apache.derby.mbeans.drda).
