Quick Beginnings for DB2 Extended Enterprise Edition for UNIX
This section describes the steps and conditions required to set up a
connection between a DB2 Universal Database DRDA Application Server and a DRDA
Before you begin, you must determine whether your connection will use the
APPC communication protocol, or the TCP/IP communication protocol.
- Supported Protocols
- APPC or TCP/IP
- APPC or TCP/IP
- The protocol you choose may depend on the application requester:
- APPC is supported by all application requesters
- TCP/IP is supported by only DB2 for OS/390 V5.1 and DB Connect
- APPC supports both one-phase and two-phase commit; TCP/IP currently
supports only one-phase commit.
- To use APPC on AIX, the optional communication support component for SNA
(db2_05_00.cs.sna) must also be installed.
- To use APPC on Solaris, the optional communication support component for
SNA (db2cssna) must also be installed.
This section gives an overview of the steps required to set
up DRDA-AS functionality. The example shows how to set up a connection
between the DRDA AS on your DB2 server and a DB2 for MVS/ESA or DB2 for OS/390
- Ensure DB2 for MVS/ESA or DB2 for OS/390 is installed and operational on
Refer to the DB2 Connectivity Supplement for information on the configuration required for the DB2 for MVS/ESA or DB2
for OS/390 AR.
- If you use APPC, ensure VTAM is installed and operational on the
Refer to the DB2 Connect Enterprise Edition Quick
Beginnings and the DB2 for OS/390 V5 Installation Guide (GC26-8970) manual
for information on configuring the DB2 for DB2 for MVS/ESA or DB2 for OS/390
- Set up the DB2 server communications, if required. (Typically, DB2
server communications are set up as part of the DB2 installation.
However, complete details are provided in Chapter 23. "Setting up Communications on the Server Using the Command Line Processor". If you want to use two-phase commit, refer to the Release
Notes for more information.)
- Update the tables at the DB2 for MVS/ESA or DB2 for OS/390 host.
Refer to the DB2 Connectivity Supplement for more information.
- Stop and restart the DB2 Universal Database instance named in
DB2SERVICETPINSTANCE (that is, the instance you updated TPName in).
Enter the following commands:
- Test the host-server DRDA connection by logging onto TSO and using
