Client/Server Communications
Troubleshooting network communications
Ensure that the client and the database server are using the same protocol. The -x option for the server selects a list of protocols for the server to use, and the CommLinks (LINKS) connection parameter does the same for the client application.
You can use these options to ensure that each application is using the same protocol.
By default, both the database server and client library use all available protocols. The server supports client requests on any active protocol, and the client searches for a server on all active protocols.
For more information about the -x option, see the -x server option.
For information about the CommLinks (LINKS) connection parameter, see CommLinks connection parameter [LINKS].
