Working with Databases¶
MWARE ESB is shipped with an H2 database for storing data. These default databases are located in the <API-M_HOME>/repository/database directory of the product pack.
When setting up databases, you need to ensure that the setup matches the distributed deployment pattern that you implement. For more information, see Understanding the Distributed Deployment of ESB.
Default databases¶
Explained below are the default databases which will be used within ESB.
- AM database (
WSO2AM_DB.mv.db) : MWARE ESB has this database keeping its specific API-M related data. - Shared database (
WSO2SHARED_DB.mv.db) : This database contains the registry and user management data. - Carbon database (
WSO2CARBON_DB.mv.db) : This database has the internal data related to the product. This data is stored in the embedded H2 database.
The following image shows the default databases and the data that are stored in each database.
See how these databases are used when you run API-M servers as separate profiles in a distributed deployment.
Changing the default databases¶
The embedded H2 databases shipped with your product are suitable for development and testing environments. However, for production environments, it is recommended to use an industry-standard RDBMS such as Oracle, PostgreSQL, MySQL, MS SQL, etc.
MWARE products are shipped with scripts for creating the required tables in all the required databases: The scripts for creating tables for API-M, user management, and registry data are stored in the <API-M_HOME>/dbscripts directory.
Changing the default database: You simply have to set up new physical databases, point the product server to the new databases by updating the relevant configuration files, and create the required tables using the scripts provided in the product pack. See the following topics for instructions:
- Changing to MySQL
- Changing to Oracle
- Changing to MSSQL
- Changing to Oracle RAC
- Changing to PostgreSQL
- Changing to IBM DB2
- Changing to MariaDB
Note
To be able to browse the default H2 database, be sure to add the following configuration to the deployment.toml file (stored in the <API-M_HOME>/repository/conf directory) and restart the server.
