Following are the datasource configuration options:

url - The URL of the database.
Info
Default port for Microsoft SSQL is 1433.
username - The name of the database user.
password - The password of the database user.
driverClassName - The class name of the database driver.
maxActive - The maximum number of active connections that can be allocated from this pool at the same time, or enter a negative value for no limit.
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.
Info
For more information on other parameters that can be defined in the master-datasources.xml file, see Tomcat JDBC Connection Pool.

If you changed the databases used for identity, copy the WSO2_CARBON_DB datasource configuration for it in < PRODUCT_HOME>/repository/conf/datasources/master-datasources.xml file and replace its default values with your custom values.
