1. Edit the default datasource configuration in the <PRODUCT_HOME>/repository/conf/datasources/master -datasources.xml file as shown below.

   Tip
   Make sure to set the following elements: validationQuery - SELECT 1; COMMIT defaultAutoCommit - false testOnBorrow - true

   Note
   Note: If you are using WSO2 Identity Server 5.7.0 or a later version, set the <defaultAutoCommit> property to true.

   Code Block
   language xml
   <datasource> <name>WSO2_CARBON_DB</name> <description>The datasource used for registry and user manager</description> <jndiConfig> <name>jdbc/WSO2CarbonDB</name> </jndiConfig> <definition type="RDBMS"> <configuration> <url>jdbc:postgresql://localhost:5432/gregdb</url> <username>regadmin</username> <password>regadmin</password> <driverClassName>org.postgresql.Driver</driverClassName> <maxActive>80</maxActive> <maxWait>60000</maxWait> <minIdle>5</minIdle> <testOnBorrow>true</testOnBorrow> <validationQuery>SELECT 1; COMMIT</validationQuery> <defaultAutoCommit>false</defaultAutoCommit> <validationInterval>30000</validationInterval> </configuration> </definition> </datasource>

   The elements in the above configuration are described below:

   Element	Description
   url	The URL of the database. The default port for a PostgreSQL instance is 5432.
   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	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.
   defaultAutoCommit	Whether to commit database changes automatically or not.
   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 enabled, each SQL statement will be committed to the database as an individual transaction, as opposed to committing multiple statements as a single transaction. Note Note: Set this property to true if you are using WSO2 Identity Server 5.7.0 or a later version.

   You can create database tables automatically when starting the product for the first time by using the -Dsetup parameter as follows: For Windows: <PRODUCT_HOME>/bin/wso2server.bat -Dsetup run For Linux: <PRODUCT_HOME>/bin/wso2server.sh -Dsetup Multiexcerpt include MultiExcerptName Dsetup-dep PageWithExcerpt Changing to Embedded Derby
