Configuring Informix® Warehouse Accelerator
You must configure the Informix® Warehouse Accelerator before you can enable query acceleration and set up the connection between the accelerator server and the database server.
About this task
Configure the accelerator server by identifying the network interface, creating a storage directory, and editing the dwainst.conf configuration file:
Procedure
- On the computer where the accelerator server is installed, log on as user root.
- Determine the correct network interface value to use for
the connection from the Informix® database
server to the accelerator server:
- Create a directory to use as the accelerator server
storage directory. Create this directory with enough space
to store the accelerator server catalog, data marts, logs, traces,
and so on.Because the amount of data in the accelerator server storage directory might increase significantly, do not create the accelerator server storage directory in the accelerator server installation directory. You will specify the file path for this directory in the value for the DWADIR parameter in the dwainst.conf file.
- Open the $IWA_INSTALL_DIR/dwa/etc/dwainst.conf configuration
file. Review and edit the values in the dwainst.conf configuration file.
Important: Specify the network interface value for the DRDA_INTERFACE parameter in the dwainst.conf file.
- Run the ondwa setup command to create the files and subdirectories that are required to run the accelerator server.
- Run the ondwa start command to start all of the accelerator server nodes.
