For information about the communication protocols and interactions between the Database Module and network components, see Figure 2, “SQL over JDBC,” on page 11.

Each database includes replicated objects and non-replicated objects. Tables are the only objects that are replicated. Non-replicated objects include stored procedures, functions, and views.

Minimal, redundant, and variable server configurations are supported in enterprise deployments. Redundant and variable configurations have replicated databases. Minimal configurations have a single database.

Data replication

During normal operation, applications send data to the primary database, which is then stored in tables. The Oracle Server uses a process called master-master data replication to constantly transfer changed data from the primary database to the secondary database. See “Data transfer” on page 7.

Consequently, in the unlikely event of failure of the primary database, the secondary database should always contain a copy of the data. See “Fault management” on page 8.

For applications, the secondary database operates in limited write mode only, which means that it is read only except for registrations. See Table 1, “Database operational states,” on page 6 and “Fault management” on page 17.

ATTENTION

Database Module deployment creates or updates both replicated objects (database tables) and non-replicated objects (stored procedures, functions, and views) on both databases.

The Database Module replication environment has the states of operation identified in Table 1, “Database operational states,” on page 6. The primary database ordinarily operates in the normal state,
