1.5 Implementation
When the gateway is installed on your host, it has some of the same components as an Oracle database instance on your host.
The gateway has the following components:
- A base file directory, similar to the one associated with an Oracle instance
ORACLE_HOME
environment variable. - A gateway system identifier (SID), comparable to an Oracle instance
ORACLE_SID
. - Oracle Net to support communication between the Oracle database and the Oracle Database Gateway for DRDA.
The gateway does not have:
- Control, redo log, or database files.
- The full set of subdirectories and ancillary files that are associated with an installed Oracle database.
Because the gateway does not have background processes and does not need a management utility, such as Oracle Enterprise Manager, you do not need to start the gateway product. Each Oracle database user session that accesses a particular gateway creates an independent process on the host. This process runs the gateway session and executes network operations to communicate with a DRDA server.
