I'd like to connect from any Linux machine to the DB2 on a Linux server
via an IP adddress (or any available method that allows us to connect
to DB2 from another machine). I know we can do it in Java via JDBC in
the following fashion (suppose my IP address is xx.x.x.xxx):
sun.jdbc.odbc.J dbcOdbcDriver=c om.ibm.db2.jcc. DB2Driver
sun.jdbc.odbc.C onnectionUrl=jd bc:db2://xx.x.x.xxx:5000 0/mydb
sun.jdbc.odbc.U serId=db2inst1
sun.jdbc.odbc.P assword=mypassw d
Is there a similar way for an application in C++ on Linux? Currently
the application has to be on the same machine as the DB2 server.
I'm using DB2 UDB Express Edition V8.2 for Linux.
Thanks. 5 3571

Install a DB2 client on the, well, client. Then you catalog the database on
the server at your client and go ahead happily accessing the database as if
it were a local one.

Hi Knut, thanks for the timely info! Is that the only way?
You always have to have a DB2 client installed on the client machine.
However, (and this is a little known tidbit of information) you can
skip the "catalog the database on the server at your client" step by
using a direct TCP/IP connection string with the SQLDriverConnec t()
API. We made use of this option to the ibm_db2 extension in PHP to
enable you to connect to arbitrary DB2 databases on any machine
(assuming you have the user ID and password).
/* Substitute database, hostname, port number, user ID, and password
values */
SQLCHAR *conn = "DRIVER={IB M DB2 ODBC
DRIVER};DATABAS E=myDb;HOSTNAME =hostname;PORT= 50000;PROTOCOL= TCPIP;UID=db2in st1;PWD=passwor d;";
rc = SQLDriverConnec t((SQLHDBC)conn _res->hdbc, (SQLHWND)NULL,
conn, SQL_NTS, NULL, 0, NULL, SQL_DRIVER_NOPR OMPT );

Please keep in mind that in V8 there is no AUTHENTICATION= keyword in
SQLDriverConnec t() connection string.
Consequently - for DSN-less connections AUTHENTICATION= CLIENT is assumed causing
- on Windows - a trip to domain controller and possible slowdown before
shipping connection to remote server.

Hello,
Is it right to tell that DB2 Connect has the same function that Oracle
Net ?
If I have an ODBC application is it also right to tell that I have 2
possibilities on my client workstation to acces a remote UDB database
on a Sun machine :
a) with a run-time client
b) with DB2 Connect Personnal Edition
Thank you

Can't we connect by just having IBM DB2 driver which is just a single

Hi All,
One programming technique to connect from one system to other is through socket programming.
Socket programming can be done using programming languages like Java,C,C++.
Are there any other programming techniques though which can be used to
1) Connect from local machine to remote machines AND
2) Transfer data from local machine to remote machines AND
3) Execute a process on the remote machines.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
