Communication protocols supported
You can use any of the supported protocols for connecting from an IBM® data server client to a Db2® server. The type of protocol that you use is dependant on the configuration of your database environment.
- connecting from IBM data server client to midrange or mainframe hosts using Db2 Connect products.
- connecting from mid range or mainframe platforms to databases on Db2.
The TCP/IP protocol is supported on all platforms on which Db2 is available.
Both TCP/IPv4 and TCP/IPv6 are supported. IPv4 addresses have a four-part structure, for example,
22.214.171.1244. IPv6 addresses have an eight-part name, where each part consists of 4
hex digits delimited by a colon. Two colons (::) represents one or more sets of zeros. For example,
Db2 database products support the SSL protocol and accept SSL requests from applications that use the IBM Data Server Driver for JDBC and SQLJ (type 4 connectivity), IBM Data Server Driver for ODBC and CLI and IBM Data Server Driver Package. Refer to Configuring Secure Sockets Layer (SSL) support in a Db2 instance.
In addition, the Windows Named Pipes protocol is supported on Windows networks. To administer a Db2 database remotely, you must connect using TCP/IP.
