Windows / .NET :: Multiple Oracle ODBC Drivers In Single Database
Jan 9, 2013
I work in a large bank in a department that produces reports for different areas of the bank. By and large, we use Microsoft Office products to interface with our Oracle databases.Recently, we had two new databases come online that use Oracle 11g - we were not using any 11g databases before this point. We have two other databases that we use that run on Oracle 10g.
Up until the two new databases were brought in, our reporting was done from systems that used 10g and 9I. We all ran the Oracle 9I driver to connect to them, and it worked very well without issue. With the addition of the 11g databases to our reporting pool, we have been forced to upgrade our ODBC connections to the 11g driver, and it has not gone well at all. I had one query that typically ran in 30 minutes take +13 hours+ to run yesterday. Speed is not the only issue, either; we have sporadic ODBC call fails, crashes, and other general failures to deal with.
Our Oracle DBAs have been trying to solve the issue, but have not yet found a solution, and each day that this goes on we fall further and further behind, as I have daily time-sensitive reports to send out that depend on this data.
One of our DBAs said she read somewhere that Oracle had not included MS Access support in the 11g driver, and that the errors were due to the imperfect connection that the driver created. I don't know of there's any truth to that, but it would provide an explanation for our troubles. We have to use Access for our reporting, as over 90% of our existing reports and processes use Access, and having to change over everything at once is just not feasible.
Is there any way to force the 9I and 11g ODBC connections to coexist, so that we don't have to use the 11g driver for our 10g databases? Or is there a better 11g driver available?
the need to use 9i Oracle ODBC drivers with 11g? What issues might be raised with this? Our application is using a very old technology and has issues, in certain functional areas, with 11g ODBC, and we found by reverting the driver to 9.0.0.2 it works.
I installed the Windows 7 64-bit ODBC drivers, but the install does not seem to have made the drivers available to all users, but rather only the installing user. This install is for an image that will be cloned as a virtual machine, so the drivers, client, settings, etc. will need to be available to anyone who logs in.
Is there a way to do the install so that all the settings and files put in by the installer will apply to all users? And if so, how do you do that?
I am attempting to connect to an Oracle 8i database via the Oracle 9.02 ODBC driver and I am receiving the following error message upon testing the connection in WinXp's ODBC Data Source Administrator dialog box: "Unable to connect SQLState=IM004 [[Microsoft]][[ODBC Driver Manager]] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed" .
I am running Oracle Client 9.2 on a P4 machine running winXP.
I'm using following connection string: +connectionString="Driver={Oracle ODBC Driver};Server=someDb;Uid=useruidr;Pwd=password"+
when I call method "Open" on "OdbConnection" I get following exception: +ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified+
"someDb" is specified correctly in tsnames.ora, "...client" and "...clientin" are added to PATH environmental variable ORACLE_HOME is set to "...client"
I have Oracle Client 11.2.0.3.0 installed Operating system is Windows 7 32 bit
When I change Driver to "Microsoft ODBC for Oracle" it works fine. However I want to use Oracle ODBC Driver.
But any of them contains install.exe or something like that...So I don't understand how to install instant client...I've found a doc on the web : " ... copy unzipped files into a folder ( ex.: C:OracleInstantClient ) and add Environment Variables TNS_ADMIN and PATH ) ... "I did it. But while adding ODBC driver with Windows admin tools , only SQL Server is available !!!.
We are running Oracle Enterprise software on various client and DB servers and we are experiencing a problem (outlined here [URL] .....) where the apparent mismatch between the oracle drivers are causing the errors.
Our db servers are using 10.2.0.4 and 10.2.0.5 drivers and the clients are using 10.2.0.1.
Firstly, are the drivers the same on the Express and Enterprise editions so that if I update a development server using Express version (I don't have the authority to upgrade the Enterprise version nor the time to commission that) and it is successful, can I reasonably expect an upgrade to the Enterprise client versions on other servers to be safe/error free, baring environmental factors of course ?
Secondly, can I upgrade to version 10.2.0.5 now or do I have to go to the 11g version only ?
I am developing an 64bit And-In software. My OS is windows7 64bit Ultimate. Developer tool is Microsoft Visual Studio 2010 Ultimate 64bit any-CUP.Server is SUN server and Oracle database 10.2.0.5 64bit enterprise edition.I have installed instantclient-odbc-win64-10.2.0.5 on my computer.I am able to connect through the command line sqlplus user/pass@server.In date source(c:windowssystem32odbcad32.exe), ODBC Driver connection successful.But in VS2010 C#, use Tools -> Connect Database,I get an error 193 (Oracle in instantclient10_2,c:ora10_64SQORA32.dll) cann't be loaded.SQORA32.dll is 32bit ODBC Driver or 64bit ODBC Driver?How can I connect database with vs2010 64bit?
Database: oracle 9i sitting on a 32 bit machine. Client: windows7 64 bit computer installed oracle 11gr2 client
Is there a way to connect to oracle 9i database from C:WindowsSysWow64odbcad32.exe on windows 7 machine? or what is the possible way to connect to Oracle 9i database?What we need is to run crystal reports from windows 7.
I'm trying to setup ODBC connection for my Oracle client while installing BO. Following are the steps I followed.
1. Downloaded the Oracle Client from the link [URL] . From that downloaded two zip files. “Instant Client Package – Basic Lite" and “Instant Client Package – ODBC”. Extracted the Zip Files to the folder I created under C: as C:Oracleinstantclient_11_2.
2. Since I'm setting up in ODBC in windows 2008 64-bit R2. I was advised to install 32 bit . So in cmd prompt, from the location C:Oracleinstantclient_11_2, ran odbc_install.
3.Created the Environment variables as i) *TNS_ADMIN - C:Oracleinstantclient_11_2* ii) *Oracle_Home - C:Oracleinstantclient_11_2* iii) *Edited the PATH variable with ;C:Oracleinstantclient_11_2*
4. Created the tnsnames.ora file in C:Oracleinstantclient_11_2. Its content are as follows. clarity_dev = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = claritydev.vip.its.ebay.com )(PORT = 1521)) ) (CONNECT_DATA = (SID = clarity) ) )
5. From the folder %windir%sysWOW64odbacd32.exe, Opens ODBC Data Source Adminsitartor. In that I found my Oracle in instantclient_11_2 and added following details.
Data Source Name : claritydev.vip.its.com TNS Service Name : clarity_dev User Id: clarity1
When I test connect it, I get error *ORA-12154:* * TNS:could not resolve the connect identifier specified*
I've seen FAQs for this error, but couldn't find anything which solves. Is there any steps I'm missing? I've checked in DB properties. It uses SID not the Service Name.
From Windows, I can successfully create and connect with a system data source using an user Oracle account.But when doing then same configuration process I can not create or connect using the 'SYS' account.
i get the error 'ORA-2009: connection as SYS should be as SYSDBA or SYSOPER'.
What is the solution to creating an ODBC DSN for the user 'SYS'?
I am creating a cross platform database application using Mono. It uses oracle database as back end. I used ODBC drive to connecting database. I can connect to database using this following connection string in my windows machine
Driver={Oracle in OraDb11g_home1};Server=localhost;Uid=system;Pwd=manager
For Linux I uses Linux Oracle OS for Database server. I installed oracle client in my fedora OS. and cofigure the client using net cofiguration assistant tool with oracle client. client connection working OK. Then I try to connect with my mono application using the following connection string
I am using DataBase Express 11g as a development site.I have developed a Delphi GUI to run with it. (32bit). All runs as expected!My associate has a Windows 7 (64bit) machine. Express installation does not supply an ODBC driver. DataBase Express installs without problem, but it is the connectivity that is the problem
I understand that 11g(full) supplies both 32 & 64 OBDC drivers.I do not want to install the full 11g database if it can be avoided.
This is going to be more of a problem the more 64bit machines get into the workplace.Is there an alternative connection method available?
Using Server 2008 Standard Edition 64 bit. We have been running full client (admin) version 10.2.0 and just installed full client (admin) 11.2.0. Both homes are in my path variable with 11.2 first.
From ODBC Administrator, I can can create new system data sources using the 11.2 client driver and the testing widget built into the data source creator says my connection is good to both 10.2 dbs and 11.2 dbs. So the 11.2 odbc driver would seem to be working.
However, from MS Access, I can only see 10.2 drivers and 10.2 data sources, which fail unless I put the 10.2 home in first place in my path.
I cannot find a way to "access" the 11.2 drivers from MS Access. If I try to create a new data source from inside MS Access, I only see the old 10.2 driver.
I installed the Oracle instant client version 10.2.0.3 and the corresponding ODBC driver. When I try to add a DSN in ODBC Manager using the Oracle driver, it crashes and I get this message:
"ODBC Administrator has stopped working" "Windows is checking for a solution to the problem..."
Trying to isolate this problem, I ran odbcad32.exe under DependencyWalker and it worked correctly without crashing. According to the Dependency Walker FAQ, this can be due to a "buffer overrun, stray/bad/freed pointer, etc.". They have a switch to set SET NODEBUG_HEAP=1 to check for this. When I did this, it crashes insider DependencyWalker also.
its possible to have multiple LGWR processes for a single database.If its possible how does the multiple processes write from redo log buffer to online redo log file.

A DB server (Oracle 11g) on Linux will support a Web Application Server (Java based) for hosting a public web site.For sending multiple INSERT statements over from the Java Server to Oracle Server, I have two ways to do it:
1) Wrap those insert statements together and send it over with one connection to Oracle
2) Send each insert statement separately to Oracle. As the result, multiple insert statements are sent and accordingly multiple connections to Oracle are needed.
Advantage of option 1 is just using one Connection. Disadvantages are that Oracle will then need to parse the statement string into multiple separate insert statements, and then loop through them to execute each. This may be costly in CPU sense.
While the option 2 may have quicker execute of each insert statement, but will need to create multiple connections.If the number of users is known and stable (such as intranet), I would prefer option 1; while for the internet there could hundreds concurrent users at the peak, I lean towards the option 2.
The best way to structure my schemas within a single Oracle instance to support multiple project development. At the moment, within an Oracle instance I have Area_Dev and Area1_Test schemas, with the intention that Project Xv1.0 would use Dev schema for development and Test schema for testing.
Lets say I want to start on Project Xv2.0 development while I am still finalizing Project Xv.10 development what is the best way of accommodating that, without creating individual schemas for each project?
How to merge multiple rows into single row (but multiple columns) efficiently.
For example
IDVal IDDesc IdNum Id_Information_Type Attribute_1 Attribute_2 Attribute_3 Attribute_4 Attribute_5 23 asdc 1 Location USA NM ABQ Four Seasons 87106 23 asdc 1 Stats 2300 91.7 8.2 85432 23 asdc 1 Audit 1996 June 17 1200 65 affc 2 Location USA TX AUS Hilton 92305 65 affc 2 Stats 5510 42.7 46 9999 65 affc 2 Audit 1996 July 172 1100
where different attributes mean different thing for each Information_type. For example for Information_Type=Location
Attribute_1 means Country Attribute_2 means State and so on.
For example for Information_Type=Stats
Attribute_1 means Population Attribute_2 means American Ethnicity percentage and so on.
I want to create a view that shows like below:
IDVal IDDesc IDNum Country State City Hotel ZipCode Population American% Other% Area Audit Year AuditMonth Audit Type AuditTime 23 asdc 1 USA NM ABQ FourSeasons 87106 2300 91.7 46 85432 1996 June 17 1200 65 affc 2 USA TX AUS Hilton 92305 5510 42.7 46 9999 1996 July 172 1100
I have database in single server. I already have ORACLE_SID=stagedb. So i want to create new sid and named as proddb.Is it possible have multiple db in single server? This server not running as RAC. It run as single only.
I have recently installed the latest Oracle 32bit client 10.2.0.3.0 on a Windows 2008 server. Installation was successful and I was able to create the required service names and test them to the Oracle database server. Now when I try to create an ODBC connection with Oracle in OraClient10g_home1, I get the following error: SQORAS32
An unsupported operation was attempted
If I install Oracle client 10.2.0.1.0, I don't get this error. It happens with the latest client. Is there any was to solve this error?
