Optionally, you can update the configuration elements given below for your database connection.

Element	Description
url	The URL of the database. The default port for MySQL is 3306
username and password	The name and password of the database user
driverClassName	The class name of the database driver
maxActive	The maximum number of active connections that can be allocated at the same time from this pool. Enter any negative value to denote an unlimited number of active connections.
maxWait	The maximum number of milliseconds that the pool will wait (when there are no available connections) for a connection to be returned before throwing an exception. You can enter zero or a negative value to wait indefinitely.
minIdle	The minimum number of active connections that can remain idle in the pool without extra ones being created, or enter zero to create none.
testOnBorrow	The indication of whether objects will be validated before being borrowed from the pool. If the object fails to validate, it will be dropped from the pool, and another attempt will be made to borrow another.
validationQuery	The SQL query that will be used to validate connections from this pool before returning them to the caller.
validationInterval	The indication to avoid excess validation, and only run validation at the most, at this frequency (time in milliseconds). If a connection is due for validation but has been validated previously within this interval, it will not be validated again.
defaultAutoCommit	Specifies whether each SQL statement should be automatically committed when it is completed. It is recommended to disable auto committingby setting this property to `true`.

Info
For more information on other parameters that can be defined in the `<EI_HOME>/wso2/broker/conf/`datasources/ `master-datasources.xml` file, see Tomcat JDBC Connection Pool.
