The downtime is limited to the time taken for switching databases when in the production environment.
Upgrading the database/registry
There are no registry and user database schema changes between AS 5.2.1 and 5.3.0. Therefore, you do not need to do any database schema migration.
- Create a new database for AS 5.3.0 and restore the backup of the old database in this new database.
- To connect AS 5.3.0 to the upgraded database, configure the following files:
<AS_HOME_5.3.0>/repository/conf/datasources/masterdatasources.xmlfile as shown in the following example:
<datasource> user manager</description> <name>WSO2_CARBON_DB</name> <description>The datasource used for registry and <jndiConfig> <name>jdbc/WSO2CarbonDB</name> </jndiConfig> <definition type="RDBMS"> <configuration> <url>jdbc:mysql://localhost:3306/<new_database></url> <username>username</username> <password>password</password> <driverClassName>com.mysql.jdbc.Driver</driverClassName> <maxActive>80</maxActive> <maxWait>60000</maxWait> <minIdle>5</minIdle> <testOnBorrow>true</testOnBorrow> <validationQuery>SELECT 1</validationQuery> <validationInterval>30000</validationInterval> </configuration> </definition> </datasource>
Go to the
<AS _HOME_5.3.0>/repository/conf/directory and update the datasource references in the
registry.xmlfiles to match the updated configurations in the
masterdatasources.xmlfile. The following are sample configurations if the datasource is “jdbc/WSO2CarbonDB”:
<dbConfig name="wso2registry"> <dataSource>jdbc/WSO2CarbonDB</dataSource> </dbConfig>
<UserManager> <Realm> <Configuration> ... <Property name="dataSource">jdbc/WSO2CarbonDB</Property> </Configuration> ... </Realm> </UserManager>
- Data Services features are no longer shipped with WSO2 Application Server. If you need to use data services hosting feature, you have two options:
Install the Data Services hosting feature from the public p2-repo. <link to p2-repo>
Use the WSO2 Data Services Server product which can be downloaded from http://wso2.com/products/data-services-server/.
- The configurations for SaaS web applications has changed in AS 5.3.0. In previous releases, SaaS configurations were enabled in the
web.xmlfile of web application by adding a context-param called
carbon.enable.saas. In AS 5.3.0, SaaS is configured via the
context.xmlfile that needs to be placed under the
META-INF/folder of the web application. See the more details about configuring SaaS applications in AS 5.3.0 from here.
Prior to AS 5.3.0, the primary keystore configured in the
carbon.xmlfile was used for securing transports. In AS 5.3.0, the keystore used for transports should be separately configured in the
The “RegistryKeyStore” configuration in
carbon.xmlis removed. See the section on configuring keystores for more information.
- Check for any other configurations that were done for AS 5.2.1 (based on your solutions), and update the configuration files in AS 5.3.0 accordingly. For example, external user stores, caching, mounting, etc.
