The following must be done to allow an application requester to use TCP/IP.
To indicate that TCP/IP is to be used to establish a connection from the online application requester, the SQLGLOB file is used. If T is specified as the communication protocol for the referencing application, TCP/IP communication protocol will be used. In this case, the DBNAME Directory remote entry of the database that is the target of the SQL CONNECT statement of the application must be set up with the necessary TCP/IP related information to be used to establish a TCP/IP connection. Refer to Setting Up the DBNAME Directory for details. For more information about the SQLGLOB file, refer to the DB2 Server for VSE & VM Database Administration manual.
Note that batch applications accessing remote servers will always use TCP/IP protocol and the SQLGLOB file communications protocol parameter is ignored.
