Optionally, you can update the configuration elements given below for your database connection.
Element Description 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.
defaultAutoCommitAnchor default_auto_commit default_auto_commit Specifies whether each SQL statement should be automatically committed when it is completed. It is recommended required to disable auto committing by setting this property to
false
false
for the MB database. This means that multiple SQL statements will be committed to the database as one transaction, as opposed to committing each SQL statement as an individual transaction.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.
