IBM DB2 Connector throws exception with .Connect() in .net

C.E.O. Gargantua

I am using the IBM DB2 Connector class of the Redistributable DB2
Run-Time Client Lite in a c# .net application using Visual Studio.

Running the code:

string myConnString = "DATABASE=192.1 68.1.43;UID=XXX X;PWD=XXXX";
DB2Connection myConnection = new DB2Connection(m yConnString);
myConnection.Op en();

Throws this error on the .Open() method:

IBM.Data.DB2.DB 2Exception: ERROR [HY009] [IBM] CLI0124E Invalid
argument value. SQLSTATE=HY009
at IBM.Data.DB2.d. a(String A_0, Int32 A_1, IsolationLevel A_2,
DB2Connection A_3)
at IBM.Data.DB2.DB 2ConnPool.a(DB2 Connection A_0, String A_1, a& A_2,
Object& A_3)

at dot400.Form1.pr ocessSqlRequest (String qs, Int32 q) in
c:\documents and settings\jbailo \my documents\visua l studio
projects\dot400 \form1.cs:line 205
How can I diagnose this?

Does my connection string look right?

The machine name on our network is AS400. If I use that as the
DATABASE name, it throws another error:

this isn't correct.
Use something like:
"Database=SAMPL E;Server=192.16 8.1.43;UID=XXXX ;PWD=YYYY;"
or with portnumber:
"Database=SAMPL E;Server=192.16 8.1.43:1533;UID =XXXX;PWD=YYYY; "

At least that's how I construct the connection strings, which do work.
I had similar issues like the ones you describe. Also if usernames
apparently don't match you get this kind of error.

The God's Awful Truth

I now see a new class of error. Are there additonal parameters I should
use in my Connection String? I am still not sure what a Database
is...MARDRPALL is a File in the $HAWLIB. Should I use the Library name?

Using the connection string:

try {

string myConnString =
"Database=MARDR PALL;Server=192 .168.1.43;UID=J BAILO;PWD=TOOTH PICK1;";

DB2Connection myConnection =
new DB2Connection(m yConnString);

myConnection.Op en();

} catch (Exception e) {Debug.WriteLin e(e.ToString()) ;}
The error is:

IBM.Data.DB2.DB 2Exception: ERROR [HY009] [IBM] CLI0124E Invalid
argument value. SQLSTATE=HY009
at IBM.Data.DB2.d. a(String A_0, Int32 A_1, IsolationLevel A_2,
DB2Connection A_3)

at dot400.Form1.pr ocessSqlRequest (String qs, Int32 q) in
c:\documents and settings\jbailo \my documents\visua l studio
projects\dot400 \form1.cs:line 205

If I use Database=Sample , or Database=$HAWLI B, the error is:

IBM.Data.DB2.DB 2Exception: ERROR [08001] [IBM] SQL30081N A
communication error has been detected. Communication protocol being
used: "TCP/IP". Communication API being used: "SOCKETS". Location
where the error was detected: "192.168.1. 43". Communication function
detecting the error: "connect". Protocol specific error code(s):
"10061", "*", "*". SQLSTATE=08001

So it seems like MARDRPALL is a database...

I'm not sure, but what I do know is that with an AS/400 you get DB2
client software, with which you can administrate the DB2 instance on the
AS/400. With that one you could browse teh DB2 instance and see which
catalogs there are..
Using the connection string:

try {

string myConnString =
"Database=MARDR PALL;Server=192 .168.1.43;UID=J BAILO;PWD=TOOTH PICK1;";

Your AS/400 is on TCP/IP or does it use IBM net? Also, did you try the
local dns name for 192.168.1.43?

Ok, so someone told me that the whole machine is a database, so I used
this connection string:

string myConnString =
"Database=as400 ;Server=192.168 .1.43;UID=JBAIL O;PWD=TOOTHPICK 1;";

That generated a new error which seems to indicate a problem with the
protocol specification.. .

IBM.Data.DB2.DB 2Exception: ERROR [08001] [IBM] SQL30081N A
communication error has been detected. Communication protocol being
used: "TCP/IP". Communication API being used: "SOCKETS". Location
where the error was detected: "192.168.1. 43". Communication function
detecting the error: "connect". Protocol specific error code(s):
"10061", "*", "*". SQLSTATE=08001

I wonder if I need to specify tcp/ip. I tried using the Net
Library=TCPIP but it threw an Invalid argument.

yes, because on an AS/400 you work inside the DB2 instance (not
entirely true, but lets say you do for simplicity).

However, what you did is not correct. Btw, The DB2 UDB .net provider
works with AS/400 if DB Connect is installed on the AS/400. Is that the
case?

How can I confirm whether it's installed or not? What command?

I have been able to use OleDb to connect...does this imply that DB
Connect is installed ?
