Create users and schemas in the database
After we have created a database, you create the schema in which all tables in the data store are held. Depending on which database you are using, you create one or more database user IDs to enable the messaging engine to access the data store tables. Before you begin this task, first create the database for your messaging engine.
To connect to WAS, create at least one messaging engine user ID. The number of user IDs you need depends on the database you use:
- If you are using Derby, DB2, or Oracle, the messaging engine can be configured to create any additional schemas that might be required for other data stores. That is, if you only create one user, it can have one to many relationships with the schemas in the database. See Configure a messaging engine data store to use a data source for details.
- For all other types of databases, the schemas must be created before starting the messaging engines that depend on them.
If a database user ID can be configured to use multiple schemas, then only that user ID is needed for all messaging engines. Otherwise the user ID is restricted to using tables in its own schema. In this case there can be only one user ID per schema.
Procedure
- Create the users and schema in accordance with the documentation for your chosen relational database management system (RDBMS). With DB2 databases, you create users and schema in separate steps. With the other databases, there is a one-to-one relationship between a schema and a user.
- Ensure that the messaging engine user ID has the privileges required to enable the messaging engine to access the data store tables and, if required, create the data store tables automatically. See Database privileges.
