Using Data Compression
Data compression over the network is enabled with a connection attribute "compress=on".
Compression occurs between the JDBC client and Data Access Server (DAS), and between the GCC client and the GCC server, so compression should be enabled on the network link as follows:
• If the DAS is local to the client and a vnode is used to reach the server then enable compression in the vnode.
• If the DAS is in the server installation then enable compression in JDBC.
• For pure Ingres Net clients, enable compression in the vnode.
An error is returned if compression cannot be enabled.
