ODXSRVR

Mapped Memory Transport

In a single-tier, Windows NT client/server environment, ODXSRVR can use mapped memory to enable thread safeness with the OA API and to increase connection speed. This is ideal for web applications that run on the same server as the database.

Each connection (instance) that uses mapped memory is thread safe in relation to other connections. However, each thread must have is own separate connection to be thread safe.

Setup

• Enable Mapped Memory in the ODXSRVR configuration file. In the GENERAL section, add the option UseMappedMemory=1.
• Add MappedMemory=1 to the [Server servername] section of the client datasource file.

A client request to use preconnected processes can use mapped memory only when mapped memory is enabled within the client datasource file. Client requests that do not have mapped memory enabled will not use a preconnected process or mapped memory. Instead, a new process will be spawned through sockets.
