The elements in the above configuration are described below:

Element Description

url

The URL of the database. The default port for a DB2 instance is 50000.

You need to add the following configuration when specifying the connection URL as shown in the example above:

Tip
Add the following configuration to the connection URL when specifying it as shown in the example above: `CLIENT_LOCALE=en_US.utf8;DB_LOCALE=en_us.utf8;IFX_USE_STRENC=true;`

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

This property is not applicable to the Carbon database in WSO2 products because auto committing is usually handled at the code level, i.e., the default auto commit configuration specified for the RDBMS driver will be effective instead of this property element. Typically, auto committing is enabled for RDBMS drivers by default.

When auto committing is When auto committing is enabled, each SQL statement will be committed to the database as an individual transactionstransaction, as opposed to committing multiple statements as a single transaction.

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