When shared memory is initialized. The sqlhosts file or registry of each database server that communicates with this database server might need to be updated. In addition, the INFORMIXSERVER environment variable for all users might need to be changed.

DBSERVERNAME configuration parameter in the chapter on client/server communications in the IBM Informix: Administrator's Guide

When you install the database server, specify the dbservername. DBSERVERNAME specifies a unique name associated with this specific occurrence of the database server. The value of DBSERVERNAME is called the dbservername. Each dbservername is associated with a communication protocol in the sqlhosts file or registry. If the database server uses multiple communication protocols, additional values for dbservername must be defined with the DBSERVERALIASES configuration parameter.

Client applications use dbservername in the INFORMIXSERVER environment variable and in SQL statements such as CONNECT and DATABASE, which establish a connection to a database server.

Client applications can connect to any coserver in Extended Parallel Server. The database server appends the number of the coserver to the dbservername to form a coserver name (unless the dbservername is a dbserver group name). You associate each coserver name with a communication protocol in the sqlhosts file. If the database server uses multiple communication protocols, additional values for coserver name must be defined with the DBSERVERALIASES configuration parameter.

For more information on coserver names, see preparing the connectivity information in the chapter on configuring the database server in the IBM Informix: Administrator's Guide.
