Oracle LU6.2 Protocol Adapter Release Notes

Release Notes

Release 52288-01

March 1997

DESCRIPTION

The Logical Unit Type 6.2 (LU6.2) Protocol Adapter is part of IBM?s

Advanced Program-to-Program Communication (APPC) architecture.

APPC is the IBM peer-to-peer (program-to-program) protocol for a

System Network Architecture (SNA) network. SNA is an IBM reference

model similar to the Open Systems Interconnect (OSI) model of

the International Standards Organization (ISO).

Program-to-program communication protocols provide services for

programs on one computer to initiate processes on another

computer, thus establishing a dialogue. Peer-to-peer communication

is independent of the following:

-computer operating system

-programming language

-hardware interface environment

APPC architecture lets the client and host communicate over an SNA

network without forcing the client to emulate a terminal (as in

terminal-to-host protocols). APPC architecture allows peer-to-peer

communication; the client can initiate communication with the server.

An SNA network with the LU6.2 and Physical Unit Type 2.1 (PU2.1)

protocols provides APPC. The LU6.2 protocol defines a conversation

between two application programs; LU6.2 is a product-independent

LU-type.

The LU6.2 Protocol Adapter lets an Oracle application on a PC

communicate with an Oracle7 database. This communication is

over an SNA network with the Oracle7 database on a host system

that supports APPC.

In addition to these server platforms, LU6.2 is available on operating

systems that are client-only platforms.

PREREQUISITES

The LU6.2 Protocol Adapter requires:

-Microsoft SNA Server version 3.0 and above

-an established LU sessions between your client machines and server

machines

CONFIGURATION

LU6.2 Protocol Adapter for Windows NT must be configured manually

using a text editor to edit the TNSNAMES.ORA and the

LISTENER.ORA files.

Address Syntax

Specify the address of a TNS-based application as follows:

(ADDRESS =

(COMMUNITY= LU62.world)

(PROTOCOL=LU62)

(TPN= tpn_name)

(MODE=ORAPLU62)

(PARTNER_LU_NAME = "partner_lu_name")

(LLU_NAME = local_lu_name)

)

Parameter Descriptions

Below is a description of the address parameters that can be used:

LLU or LOCAL_LU:

Identifies the local LU alias. This parameter cannot be used with

LLU_NAME.

LLU_NAME or LOCAL_LU_NAME:

Specifies the local LU name; must be a fully qualified name. This

parameter cannot be used with LLU.

MODE or MDN:

Identifies the log mode entry of the LU6.2 session; the value is

typically ORAPLU62.

PLU or PARTNER_LU_NAME:

Identifies the Oracle7 Server; must be a fully qualified name. This

parameter cannot be used with PLU_LA.

PLU_LA or PARTNER_LU_LOCAL_ALIAS:

Identifies the partner LU alias of the Oracle7 Server. This parameter

cannot be used with PLU.

TP_NAME or TPN:

Identifies the transaction program name of the host machine. This

parameter is not required for a connection to an MVS host.

TNSNAMES.ORA Examples

Example to connect to IBM MVS instance:

mvs.world = (DESCRIPTION =

(ADDRESS =

(COMMUNITY= LU62.world)

(PROTOCOL=LU62)

(TPN=RECVTP)

(MODE=ORAPLU62)

(PARTNER_LU_NAME = "ORACLE.TNSORAK")

(LLU = SENDLU)

)

(CONNECT_DATA=(SID=ORCL)

)

)

Example to connect to Windows NT listener:

nt.world = (DESCRIPTION =

(ADDRESS =

(COMMUNITY= LU62.world)

(PROTOCOL=LU62)

(TPN=RECVTP)

(MODE=ORAPLU62)

(PARTNER_LU_NAME = "ORACLE.HQEW001")

(LLU = SENDLU)

)

(CONNECT_DATA=(SID=ORCL)

)

)
