Using shared memory access (SMA) with IBM InfoSphere CDC replication
To use SMA with IBM InfoSphere CDC replication, you need to start an SMA server and enable a local SMA connection between the IBM InfoSphere CDC replication for solidDB® instance and the SMA server.
Before you begin
For SMA connections, the solidDB® server and the IBM InfoSphere CDC replication engine must be located on the same node.
Procedure
1 Check that the location of the SMA driver library is included in the LD_LIBRARY_PATH or LIBPATH (Linux and UNIX) or PATH (Windows) environment variable.
For details, see “Configuring your environment for SMA use with Java” in the solidDB® Shared Memory Access and Linked Library Access User Guide.
2 Create a symbolic link for the SMA driver library (ssolidsma70), without the file type extension, in the <solidDB installation directory>/bin directory.
For example in Linux operating systems, use the following command:
ln -s ssolidsma70.so ssolidsma70
3 Start the SMA server by entering the command solidsma at the command prompt.
4 Configure the IBM InfoSphere CDC for solidDB® instance to use an SMA connection when connecting to the solidDB® server.
Use the IBM InfoSphere CDC for solidDB® configuration tool (dmconfigurets) to enable the SMA connection.
Operating system
To enable SMA connections with dmconfigurets
Linux and UNIX
Select the Single server configuration type.
For the Enable SMA option, type y and press Enter.
Windows
In the Server area of the New instance or Edit instance dialog, select the Enable SMA check box.
When you select Enable SMA, the solidDB® connection propertysolid_shared_memory=yes is added to the connect string.
