9.6.5 DB adapter

The service platform allows you to execute SQL on a database from a DB (database) adapter. The following figure shows an overview of an SQL execution request for a database from the DB adapter.

Figure 9-12 Execution of SQL from the DB adapter

[Figure]

The service requester (application that sends execution requests (request messages) for services to the HCSC server) receives an execution request for a service component, and then sends a request message to the DB adapter.

The DB adapter sends a message that requests execution of SQL on a database defined in the adapter, and then executes the SQL.

After execution of the SQL finishes, a response message is sent to the DB adapter as the execution result. The person responsible for the business operation is notified of the response message via the service requester.

Note
Only the following databases can be used as execution targets when you use the DB adapter to execute a service component (database operation):
  • HiRDB/Single Server (Version 8)
  • HiRDB/Parallel Server (Version 8)
  • HiRDB Server (Version 9)
  • Oracle 11g
  • Oracle 12c
