Protocol addresses using the SPX or LU6.2 protocol must be replaced. Oracle Net provides support for the following network protocols:
1) TCP/IP, 2) TCP/IP with SSL, 3) Named Pipes, 4) SDP
The protocol.ora file is required when "unusual" protocols are introduced into the Oracle environment, rendering the default protocol settings inappropriate. The protocol.ora file also defines node-specific and protocol-specific addressing information for certain non-standard protocols.
The following protocols require parameters to be listed in protocol.ora:
- APPC/TCPIP
- ASYNC
- X.25
- OSI4
Following is a sample protocol.ora file for cross-protocol communications between LU6.2 and TCP/IP:
PROTOCOL.ORA
LOCAL_LOOKUP.dilbert=
(ADDRESS_LIST=
(ADDRESS=
(PROTOCOL=tcpip)
(CONNECT_PROFILE=hnl1)
(MODE=ORALU62)
(TPN_PROFILE=HSW)
))
For a unified protocol environment such as TCP/IP, the protocol.ora file is not used.
But there is one significant exception to this rule, which we will look at in the next lesson.
