Oracle 64-bit and database connectivity toolkit

Hello- I am attempting to connect to an Oracle database by interfacing the databse connectivity toolkit with the Oracle 10.2.0.3 64-bit that my customer uses. I am running LV13 32-bit on their machine. I am unable to connect to the database. Are there any known issues with this type of setup?

There's some discussion about an unsupported method to use the Database Connectivity Toolkit with 64-bit Windows here: http://forums.ni.com/t5/LabVIEW-Idea-Exchange/64-bit-Database-Toolkit/idi-p/2170088
That may help with the problem you're seeing. Something else to consider is the manual (page 1-2):
The Microsoft ODBC driver for Oracle and the Microsoft OLE DB
Provider for Oracle do not support BLOB (binary) data types. You
cannot use Oracle with the Database Connectivity Toolkit for binary
data with these drivers. Instead, use the OLE DB Provider and ODBC
driver that Oracle provides. Refer to the Oracle Web site at
www.oracle.com for more information about the OLE DB Provider
and the ODBC driver that Oracle provides

LabView 5.1 and Database Connectivity Toolkit Compatibility?

I am looking to serve some data from a LabView 5.1 application up to an Oracle 8i database. I have looked at the current Database Connectivity Toolkit (which uses ADO technology), but am not sure if this will be compatible with LabView 5.1... is it? If not, what are my alternatives? Are older versions of this toolkit available?
Thanks!

Also, could someone touch on how forward compatible LabView applications are? In this scenario, I have the same 5.1 application which now requires some database connectivity. Since the SQL Toolkit is no longer supported, I would be left with upgrading LabView to 7.0 and using the Database Connectivity Toolkit. How well (in general) do earlier LabView applications convert to newer versions?
Thanks again!

Oracle service bus and database connectivity

Since currently OSB does not support Adapter Framework, what are currently options for using DB Adapter type functionality in Oracle Service Bus (ALSB).
It seems JMS and other transports are very well supported, but how do we use DB Services?
Please if someone can provide some insight into this.
thanks

Oracle Service Bus 10gR3 contains the JCA framework which will eventually allow us to exploit the whole set of JCA adapters currently in use in BPEL Process Manager. Over the next few months several JCA adapters will be certified to be used with Oracle Service Bus - the Database adapter is one of the first of these.
As for SOA Suite and WebLogic bundling, let me explain. SOA Suite contains the following products:
BPEL Process Manager
Business Activity Monitoring
Business Rules
Web Services Manager
Complex Event Processing
B2B
ESB (the old Oracle ESB product)
Service Bus (formerly AquaLogic Service Bus from BEA)
This does not come with an application server as the suite is hot-pluggable (i.e. can be used with a number of application servers). However, the preferred (and cheaper) approach is to purchase SOA Suite and WebLogic Suite (which contains iAS, WebLogic Enterprise Edition, Coherence, JRockit with 100ms deterministic garbage collection and WebLogic Operations Control). This is because some of the elements of the SOA Suite only currently run on iAS (B2B) and some only run on WebLogic Server (Oracle Service Bus) although in the future these will also become hot pluggable.
To find out more, check out the SOA Suite and WebLogic Suite pages below:
[SOA Suite|http://www.oracle.com/technologies/soa/soa-suite.html]
[WebLogic Suite|http://www.oracle.com/appserver/weblogic/weblogic-suite.html]
You will find the DataSheets are particularly useful for giving you an overview of the suite.
Hope that helps.

OLE Objects and Database Connectivity Toolkit

I am trying to insert and image (jpg) that is created in Labview into an Access database as an OLE object. How do I go about making this conversion, or are there any other suggestions?

Hello -
Have you tried any of the shipping examples for the database connectivity tookit? You can find them by navigating Help >> Find Examples >> Toolsets and Modules >> Database Connectivity. The Insert Example.vi may help you get started. Click here to access database examples posted on the Developer Zone.
Please let me know if any of these examples helped. If not, can you provide more information about the version of LabVIEW and Access you are using? Thanks! Have a great day!

Why do I get a class conflict between the Prepare SQL.vi and the Get Column Name.vi with the SQL Toolkit compatibility vis from the Database Connectivity Toolkit?

I have done extensive programming with the SQL Toolkit with LabVIEW versions through 6.1. My customer now wants to upgrade to Windows 7, so I am trying to upgrade to LabVIEW 2009 (my latest purchased version) using the Database Connectivity Toolkit, and the SQL Toolkit Compatibility vis. Everything seemed to be going okay with the higher level SQL operations, but I ran into trouble with the Get Column Name.vi.
The pictures below show the problem. The original SQL Toolkit connected the Prepare SQL.vi with the Get Column Name.vi with a cluster of two references, one for connection, and one for sql. The new compatibility vis have a class conflict in the wire because the Prepare SQL.vi contains a cluster with connection, and command references, but the Get Column Name.vi expects a cluster with connection and recordset references.
How do I resolve this conflict?
Thank You.
Dan

I've never worked with the old version of the toolkit, so I don't know how it did things, but looking inside the SQL prep VI, it only generates a command, and the the column name VI wants a recordset. I'm not super familiar with all the internals of ADO, but my understanding is that is standard - you only have the columns after you execute the command and get the recordset back. What you can apparently do here is insert the Execute Prepared SQL VI in the middle and that will return what you need.
I'm not sure why it worked before. Maybe the execute was hidden inside the prep VI or maybe you can get the column names out of the command object before execution. In general, I would recommend considering switching to the newer VIs.
Try to take over the world!

I run Dev 6i on Windows 2008 R2 64-bit,the forms are working fine after connection to the database but the reports continue to request for username, password and database connection string every time i try to open a report.

I receive REP-0501: Unable to connect to specified database. I run developer 6i application on windows 2008 r2. I have applied the nn60.dll and nnb60.dll files to the \BIN directory. The forms are working fine. The reports will only display after the correct user id (username, password and database connection string) is supplied. This is happening to all attempts to open already complied form. Pls, help.

If you are connecting to an Oracle 11g database, remember that by default the passwords are case sensitive. To disable that, run
ALTER SYSTEM SET SEC_CASE_SENSITIVE_LOGON = FALSE;

I am using the database connectivity toolkit to retrieve data using a SQL query. The database has 1 million records, I am retrieving 4000 records from the database and the results are taking too long to get, is there any way of speeding it up?

I am using the "fetch all" vi to do this, but it is retrieving one record at a time, (if you examine the block diagram) How can i retrieve all records in a faster more efficient manner?

If this isn't faster than your previous method, then I think you found the wrong example. If you have the Database Connectivity Toolkit installed, then go to the LabVIEW Help menu and select "Find Examples". It defaults to searching for tasks, so open the "Communicating with External Applications" and "Databases" and open the Read All Data. The List Column names just gives the correct header to the resulting table and is a fast operation. That's not what you are supposed to be looking at ... it's the DBTools Select All Data subVI that is the important one. If you open it and look at its diagram, you'll see that it uses a completely different set of ADO methods and properties to retrieve all the data.

Labview Database Connection Toolkit and decimal point

Hi,
on my system I use "," (comma) as decimal point.
In Labview Options I unflagged "Use localized decimal point", and numeric controls and indicators use "." (dot) as decimal point.
The problem is that Labview Database Connection Toolkit keeps returning floating point numbers as strings with comma as decimal point.
Has anyone experienced this issue?
Is this related to Labview or MySQL ODBC Connector (that I'm using to connect to a mySQL DB)?
Thanks in advance for any help,
Marco

You have two or three places to look. First there is the DCT. Second, there's a couple layers there that could cause problems (the mySQL drivers and ADO) and then there's even the posibility that the issue could be in the DBMS itself.
I would start by burrowing down through all the DCT layers and find the spot where the results are actually being read back fromt he database. If the resutls are read as variants and converted to LV datatypes, the problem is on the LV side. If the values are being read as strings and converted, the problem coiuld be on the other side.

Database connectivity toolkit problem with WINDOWS VISTA and Microsoft jet 4.0 provider

Hi again,
I'm experiencing a problem with Database connectivity toolkit and Microsoft Jet 4.0 provider (MS ACCESS mdb database).
I was able to get my application to work properly on my PC: WINDOWS XP PROFESSIONAL, VERSION 2002, SERVICE PACK 3 and Msjet40.dll ver. 4.0.9511.0 (Windows XP SP3 and Security Bullettin MS08-028).
The same connectivity toolkit seems to have problems (although I didn't get any error dialog) on a laptop with WINDOWS VISTA ULTIMATE, SERVICE PACK 2 and Msjet40.dll ver. 4.0.9755.0.
Does anyone have an idea whether it is a sort of compatibility issue or a different thing?
Would it be possible to include my DLLs into the installer in such a way LabVIEW application calls those DLLs instead of the ones it finds on the host PC?
Thanks a lot. Any suggestion or advice very welcome and appreciated.

I ran into this with Windows7 64 but, could not get the jet 4.0 to work. Endnd up dumping access and used sql server express, its free, and all my code worked fine, just used a different UDL to connect. I wasted lots of time trying to find a way of getting the jet4.0 to work with 64bit windows.

Problem with database connectivity toolkit

I have problem with Labview database connectivity toolkit. I build and deploy the real_web.vi (attached to the post) to the web server. It seems that the DB Tools Open Connect can not connect to the data base, and it issues the following error:
NI_Database_API.lvlib:DB Tools Open Connec (String).vi->real_web.vi->real_web.vi.ProxyCallerADO Error: 0x80004005 Exception occured in Microsoft OLE DB Provider for ODBC Drivers: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified in NI_Database_API.lvlib:DB Tools Open Connec (String).vi->real_web.vi->real_web.vi.ProxyCaller
But in highlight execution, I do not get this error! My program connects to the database and read the data. What is wrong ?
Moreover, when I connect to the vi using the web-browser, the cpu usage of ApplicationWebServer process goes up to 100% (The same problem as stated in this post).

Say what you will about the problems that the DCT can cause (and goodness knows I have) my suspicion is that this is not a toolkit ptoblem. When ever something only works with execution highlighting on, two words should immediately jump to mind: "race" "condition".
Execution highlighting will muck aound with the order in which things get done in your code. Can you post what your code looks like?

LabVIEW Database Connectivity Toolkit Parameterized Query Property Wildcard

Hi,
within my LabVIEW application I successfully implemented a SQL statement
like
SELECT *
FROM table_name
WHERE property 1 = 123
AND property2 = "abc"
with help of the Database Connectivity Toolkit. I first created a parameterized
query, then set each parameter and afterwards executed this query.
But now I want to use wildcards within this statement. Does anybody know
how to use wildcards with both integer properties and string properties?
Is this possible while using the normal parameterized query vi?
Thanks in advance for your help.
Regards
Michael

Hi Michael
You can use "LIKE":
SELECT * FROM table_name WHERE property 1 LIKE '12%'
% represents multiple characters (e.g. entries with property 1 123 but also 1240 would be selected)
_ represents one character
Hope this helps.

LabView database connectivity toolkit 1.0.1 compatibility with MS-ACCESS 2010 / Labview report generation toolkit for Office 1.1.3 compatibility with Office 2010

In the very near future we will be forced to upgrade to Office 2010 Company wide and I am a little concerned with some of our older test platforms that have applications built in LabView 8.2.1. These applications save data to MS-ACCESS 2000 databases using the LabView database connectivity toolkit 1.0.1. Office 2003 is also loaded on these test platforms with all test reports generated using the LabView report generation toolkit for Office 1.1.3.
I have not gotten my hands on a copy of Office 2010 yet to see if there will be any compatibility issues. Does anyone have any experience in this area?

The MS-Access part is fairly well isolated through the ADO interface LabVIEW uses. The only possible problems there IMHO are difficulties with possible Acess compatibilities itself such as an example, SQL statement you may have invoked directly through the ADO interface. Maybe you did use a depreciated command back then that has since been removed. As long as the only thing you do are simple INSERT and SELECT statements only, I would expect it to just keep working.
The Report Generation interface is a different beast. Microsoft manages to change the Automation interface with every version of office in a way that strongly binding applications like LabVIEW break on. There is no good way around that except not changing those methods, but that is a cause that has been lost already. You will certainly have to verify the version dependant Report Generation API VIs to still work with Office 2010 and most likely you will have to make some changes to those VIs to make them work again with the modified ActiveX interface of Office 2010. Note, that I have no experience with porting report generation to Office 2010 but I have had some headaches from porting that between Office 97, 2000, 2003, and 2007.

Error 3005 using Database Connectivity Toolkit

I'm using the LabVIEW Database Connectivity Toolkit, version 1.0.132 with LabVIEW 8.5. When it tries to create an ADODB.Recordset object in the Conn Execute.vi, the "Automation Open" function node throws error 3005, "The specified object can't be created".
I've read somewhere that this may be related to an unregistered DLL or ActiveX component. Is there a way to find out what DLL this function uses? Any suggestions on other things to look for?
Thanks,
Mike

Good Evening Mike,
This Knowledge Base article seems to show a solution to a similar issue. Let me know the results and if you see any errors in the process.

Database connectivity toolkit broken vi's

hello all,
I upgraded from LV 8.5 to 8.6 (windows XP platform) a couple of weeks ago and have had no issues until today when all of sudden my Database toolkit vi's are coming up broken, with: "One or more required inputs to this function are not wired or are wired incorrectly. Show the Context Help window to see what the connections to this function should be." errors however this is not happening on all my vi's using objects from the tool kit.
Actions taken to date with no success:
1. mass compile of all my vi's
2. mass compile of database toolkit
3. re install Database toolkit
4. mass compile the vi.lib directory
5. as per the old knowladge base article Document ID: 2RO7J544, ensured latest microsoft MDAC is installed.
Any help is appreciated as we use this toolkit extensivly.
thanks

Solved!

Hi Chris,
Thanks for the reply and I hope your well.
I need to try to understand something, when you say upgrade to LabVIEW 8.6 did you upgrade the toolkit?
LabVIEW Database Connectivity Toolkit 1.0.2 is for LabVIEW 8.6. If, on the other hand your trying to use LabVIEW 8.6 with DC Toolkit 1.0.1 then I beleive they are not offically compatible. However, these KnowledgeBase links maybe of interest: (after all they are just VIs). However, saying this - if you read the readme for the new toolkit several things have changed for LabVIEW 8.6 - so becareful.
You will have to manually copy all the files over from one version of LabVIEW to another. Use the following instructions to accomplish this:
Install the Database Connectivity Toolset to the lowest version of LabVIEW, say X.
Copy the following files/directories to the appropriate directories in the later version of LabVIEW, say Y.
Copy the database directory from \LabVIEW X\vi.lib\addons\ to \LabVIEW Y\vi.lib\addons\
Copy the database.llb file from \LabVIEW X\project\ to \LabVIEW Y\project\
Copy the database directory from \LabVIEW X\examples\ to \LabVIEW Y\examples\

I would also check that you Installed the tookit for LabVIEW 8.6 - toolkits are now specific for labVIEW 8.6. So maybe try re-installing and the toolkit for LV8.6.
Hope this helps and please let me know (please clarify a little more),

Database connectivity toolkit -- create table

Is it possible to implement the SQL command of AUTO_INCREMENT for the 1st column while creating table right at the start? ie making use of the "create table.vi" in the database connectivity toolkit?
I know this can be done if i execute the SQL Command via the "execute query.vi". Just asking if there might be a better way. Thanks.
Hope to achieve a similar output as shown below where the 1st column is set for auto-increment:
No | Name| Age
1   | John  | 25
2   | David | 28
3 | .....      | ....
4.....
5 .........

Hey HWJ,
I checked around and I think that the "execute query" method would be the best way to go about doing this. I couldn't find a VI that had the AUTO_INCREMENT option and checked the Database Connectivity Toolset Manual and didn't find any reference to that command. Please let me know if you have any further questions!
