C# VS2010 Win7 64-bit iSeries Access ODBC Driver Communication link failure - windows

I'm having a problem upgrading a c# app from WinXP to Win7 64 bit. The app queries data from our iSeries. I've set up a 64 bit ODBC DSN, which works if I try from within MS Access. But, when I try to establish a connection in the C# code, I'm getting the following error:
ERROR [08S01] [IBM][iSeries Access ODBC Driver]Communication link failure. comm rc=10022 - CWBCO1003 - Sockets error, function returned 10022
My connection code is as follows:
cn = new OdbcConnection("dsn=as400data;UID=user;PWD=password;");
cmd = new OdbcCommand(sql, cn);
cn.Open();
Anyone have any ideas as to what may be raising this error?

I'll put this here in case someone else has this problem one day.
The resolution to this problem was to put the code under development directly on the C:\ drive of the development machine. Typically, I keep my code out on a network drive, so that it gets backed up. There's some kind of issue with doing that in Win7, however.

Oracle ODBC connection failure (using oracle's stock ODBC drivers)

Want to use an Oracle-ODBC connection in Visual Studio 2017/ SSIS as it's much faster than OLE DB during tests.
Problem:
I follow Oracle's steps to the letter.
Install instant client (v18, also tried v12).
Download/ extract ODBC download in same library. Run odbc_install.exe.
See the Driver in 'ODBC Data Sources/ Admin' in Windows 10.
Add new User Data Source. TNS Service names pull up fine. Test
Connection (User/ Pass) -- it works!! The Connection works!!
I tried this with 64 bit in Oracle, their instant client v18.3 or 12.2 both. All works in Window's "Oracle Source Administrator" via test connections.
I tried this with 32 bit downloads as well. All is good.
Now, open Visual Studio. First tried 64 bit (my Windows OS is 64 bit, but Visual Studio Data Tools is only 32 bit). Had a hunch it wouldn't work.
Error message "system architecture and client is not the same" or such. Gotcha.
Tried the 32 bit Oracle ODBC driver (User Source). I keep getting the same message (tried 18_3 and 12_2 versions).
Now .... SQLORA32.dll is in the very file path it named. It's right there! Why can't it be found? The test connection in ODBC Source Admin works! What is going on here?
And I'm unsure if I have to "register" something via the command line, I had to do that once before, maybe it was an unrelated issue.
To boot, when I tried a 3rd party "Devart Oracle ODBC connector" -- it's a simple 5-second install wizard that works flawlessly instantly. Problem is it's a 30-day trial and costs $150 at least. How can I can get an Oracle-created ODBC connector (Oracle being world-renowned for janky-azz products) to actually work?
Devart, and probably Attunity Oracle ODBC: 5 second installs
Oracle's own: Harder to install than breaking into Fort Knox/ learning Mandarin Chinese. Please advise.
I am answering my own question.
Unfortunately some of us ETL/ BI guys need to go so wide on problems that there's no time to figure out every little detail/ glitch of Oracle's ... whatever they're doing now.
But here's a fix. In Visual Studio 2017/ Data Tools/ the SSIS IDE .... if you want an Oracle ODBC connection (Faster than OLE Db for some reason) --- when you're setting it up, instead of selecting a NAMED "user or system data source" that you created in ODBC Source Administrator, simply using the "Builder" option (to the left of Use Connection String) for a connection string. It does the exact same steps as the ODBC Source Admin, but within Visual Studio. I don't know what the difference is here, but some wizardry/// who knows what is different, and the connection somehow, suddenly, for some reason, works.

Reporting services Data Source to Oracle

We have set up Data Source to Oracle on our SSRS 2008 reporting manager as simply:
Data Source: Oracle (from drop down list) Connection string: Data
Source=SERVERNAME;Unicode=True
And it all works fine until something happens - we assumed after windows updates.
This connection doesn't work. The error is:
"Attempt to load Oracle client libraries threw
BadImageFormatException. This problem will occur when running in 64
bit mode with the 32 bit Oracle client components installed."
We do have 32bit Oracle driver on this server. I don't know if there is a 64bit one already.
Then we have created another one to ORacle but is ODBC:
Data Source: ODBC (from drop down list) Connection string:
DSN=SERVERNAME;
After this one is tested for connection (with the button in the properties window) the first one starts working.
And then we continue with the Oracle Data Source as usual and until the next failure. It happened couple of times so far and the solution is just to open the ODBC connection, hit "Test Connection", that works fine. Then go back to Oracle data source and that one works.
It is very unreliable to operate reporting service for the users and also annoying for staff as we don't have a solution.
Any ideas for what we might be looking on that server to have it working 100% of time?
You are running your SSIS package in 64 bit mode but attempting to access a 32 bit driver.
Either (a) switch to 32 bit mode or (b) uninstall your 32 bit driver and install the 64 bit one. You really do not want both 32 and 64 bit on the same server :-)
As to why it is happening infrequently? Hard to tell because there is insufficient information in your question.
If your windows is is 64 bit, and oracle client is 32 bit,
install both clients (32 and 64 bit) in separate folder path with same tnsname file and restart SQL Server Reporting Server service. It get solved for me.

deployed pb App transaction not connected

I have deployed a PB App created with PB12.5 Classic. Its a PB winform app. I have managed to deployed it on a test unit to test its performance. I have created a custom runtime packager.
this runtime packager that i have created consists of basic PB runtime DLL, which is the PBDWE125.dll, PBSHR125.dll PBSNC125.dll, PBVM125.dll as per sybase's instruction in infocenter.sybase.com.
i have also packaged microsoft dlls which is the atl71.dll, libjcc.dll, libjtml.dll, msvcp71.dll, msvcp100.dll, msvcr71.dll, msvcr100.dll and nlwnsck.dll.
all of these dlls are installed in C:\Program Files\Sybase\Shared\PowerBuilder.
my problem is, my PB app is running BUT WHEN I TRY TO ESTABLISH CONNECTION my database server it prompt "Transaction not Connected"
is it the PBSNC problem? i tried registering it using regsvr32 and it didnt work. i have used PB runtime packager but still no luck. i have tried the app path registry and link it to the directory stated above and still no luck...
my question is
is there anything that i can do to make this work?
win 7 has c++ runtime libraries installed already right?
what can be the cause of "transaction not connected" error
what can i do to make it work?
note:
i have user access to the database server
i can access the database server
the app is working when the PB IDE is installed
please enlighten me! thank you :D
Does the computer that the app is deployed to have the SQL Server Native Client runtime installed? (I'm assuming you're using SQL Server because you mention PBSNC125.dll.) Here's some info from a blog post I wrote a while back (I was using PB 12 and SQL Server 2008, so things may be different for you.)
Files Required
On your client machines, in addition to the PB runtimes (including PBSNC120.dll, which is for SQL Server), you also need to install the SQL Server Native Client runtime. These come as an msi installer package from Microsoft. When you install the SQL Server client, you'll need to do so as an administrator. Otherwise you'll get a cryptic error message along the lines of "0: -1".
There's a 32-bit and a 64-bit version of the runtime. The 64-bit version won't run on a 32-bit version of Windows and vice versa.
Footnote: My project used PowerBuilder Classic version 12.1 and SQL Server 2008
"Transaction not connected" usually comes from a DataWindow being given a transaction object that isn't connected to the database. It sounds like there isn't much error trapping when you connect to the database, and you're getting a down stream symptom. You need to add error checking to your CONNECT routine, and that will give you more clues as to what is going on.
One of the more common problems with connections on deployment is when programs try to read connection parameters from an INI file, and on deployment the app can't find the INI file, so with no error checking on reading the INI, the program is trying to connect with an empty transaction object and fails. However, the information you've given us is too late to have any clues whether that is the problem or not.

Error occurs while install Oracle BIEE

I'm trying to install Oracle BIEE 11g on my computer, but something wiered happend.
I've tried on a x86 computer with 2GB memory and a x64 computer with 4GB memory. Both of them are running Windows OS. I want to connect a MS-SQLSERVER database, and I've finished creating related DEV_ tables using RCU.
I followed the tutorial from the doc.oracle.com, but then I stopped at the 14th step, it says "设置数据库连接失败". I can continue install, but another error occurs, service obisch1 cannot start. I can open localhost:9704 after installation, but it will return a 500-error after I restart my computer.
I searched the internet, it says I should set my database source using "Net Manager" Tool, but I don't know how. And after install I got a database source using driver "MERANT OEM 5.3 32-BIT SQL Server Wired Protocol", but I can't make change to it, cause the system says can't find the driver...
I don't know what to do now... Anybody can help me? Thanks very much.
Well, I've kind of solved it.
I still don't know why my computer cannot find the odbc drier "MERANT OEM 5.3 32-BIT SQL Server Wired Protocol", which seems to be the reason why I can't connect to the database at the 14th step while I install OBIEE.
However, I add an odbc-connect through the system's function, I found it in the control panel.
On the other hand, the url http://localhost:7001/em and http://localhost:7001/analytics can be still accessed(after a long time, it can be accessed).
So, then I create a rpd file use my own odbc-connect, and it seems work fine.
Thanks everybody, anyway, and hopes can help

adhoc queries using opendatasource microsoft.ace.olebd.12.0 reading excel file

adhoc queries using opendatasource microsoft.ace.olebd.12.0 reading excel file
Everthing was working fine on my local even on production for a long time already "months". As long as the user is a sysad.
And then, just all of a sudden the script using OpenDataSource using microsoft.ace.olebd.12.0 raised an error
OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "(null)" returned message "Unspecified error".
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "(null)".
No one is altering the script
No one has updated the server nor my local.
All of the servers for different apps that uses the script encoutered the error.
I'm really confused already on what happened on the driver? Is this some kind of a expiration on the ace driver??
Hope someone could help me.
Do you still have this issue?
Is it a x32 or a x64 server?
Did you install any windows update?
I get this error using AccessDatabaseEngine_x64 driver, and then just installed the x32 driver (no x64 removal) and it worked just fine. The might be a dll dependency or something. Check if you had any windows update regarding these drivers.
Hope you fixed your problem :D
Regards
