Windows :: Cannot Load Oracle.DataAccess.dll
Mar 18, 2011
He has a Windows 7 64 bit laptop and wants to install Oracle Instant Client into it.
Hs has just installed the Oracle Client on his machine and after that he had installed the Oracle Data Access for 64 bits [URL] it still doesn't have the Oracle DataAccess assembly avalaibale. When we look into C:WindowsAssembly we only have the X86 version installed.
He already has Visual Studio 2010 installed on his machine.
Using a tool like Navicap the connection is made possible ...

I have a console application that needs to be scheduled in task manager. My system is 32-bit operating system and I’m using Oracle.DataAccess.dll in my application to establish connection to the oracle db. The version is 2.112.1.0 and the processor architecture of this dll in C:WindowsAssembly is x86. In my local m/c this dll works fine with all 3 build and target platforms – x64, x86 or AnyCPU. But when I copy the files to my staging server which is a 64-bit OS I’m getting the following exception. (Note: I’m also having Oracle.DataAccess version 10.2.0.100 which is also x86 available in C:WindowsAssembly)
System.BadImageFormatException: Could not load file or assembly 'Oracle.DataAccess, Version=2.112.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. An attempt was made to load a program with an incorrect format.
File name: 'Oracle.DataAccess, Version=2.112.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342' at
Assembly manager loaded from: C:WindowsMicrosoft.NETFramework64v4.0.30319clr.dll
Running under executable D:ProjectFolderMyExecutable.exe

I have tried to build the application to target AnyCPU / x64 / x86. It fails in all 3 scenarios. There are other applications in the staging server where Oracle connection can be established. So ODP.Net should be registered in the server. So looks like problem with my console app.

I'm using powershell for querying all our oracle instances and for this purpose I use Oracle.DataAccess. Before I upgraded to Windows 7 64bit from 32bit it had worked fine but now I get this message:
+[Reflection.Assembly]::LoadFile("c:oracleproduct11.2.0client_1ODP.NETin2.xOracle.DataAccess.dll")+
GAC Version Location
False v2.0.50727 c:oracleproduct11.2.0client_1ODP.NETin2.xOracle.DataAccess.dll
I have tried different versions of ODAC or Oracle clients but no success, still not properly loaded neccessary library or mismatch in versions.

We have a .NET application on windows server 2008 32bit using the stored procedures on an Oracle 10g environment. We are trying to deploy the .NET application onto a 64bit x86 Windows server 2008.
We face an error trying to install the x64 version of the Oracle 10g client on windows 2008. The error we get is Problem signature:
Problem Event Name: APPCRASH
Application Name: javaw.exe
Is the x64 version of the Oracle 10g client certified for Windows 2008? Has anyone successfully installed the 64bit version of the oracle client on win2008?
We have a workaround in place with 32 bit version of the client running with the 32 bit version of the .NET application on x64 win2008. However to maximize the infrastructure we need to use the 64 bit version or we would have to turn to MSSQL Server .

I'd like to talk about some interesting behaivor with Oracle RAC load balancer.We have Oracle RAC 11.1.0.6 - 2 nodes.
We noticed sometimes the number of sessions { select count(1) from v$session; } was not divided equally between nodes. Also load average was very different between node #1 and node #2.Now we define service explicitly.
srvctl add service -d MYORCL -s MYSERVICE -r MYORCL1,MYORCL2
srvctl config service -d MYORCL -a
MYSERVICE PREF: MYORCL1 MYORCL2 AVAIL: TAF: NONE
After we change connection string of corresponding application(s) the spread will be more equal:
select service_name,inst_id, count(*) the_qty
from gv$session
where service_name = 'MYSERVICE'
group by service_name, inst_id
SERVICE_NAME INST_ID THE_QTY
---------------------------------------------------------------- ---------- ----------
MYSERVICE 1 68
MYSERVICE 2 79
Although it's not round robin algorithm, the distribution looks more equal. It seems explicitly defined service of Oracle RAC has better load balancing approach comparing to the default service (created with db by default).
But there is some downside with more 'equally' distributed load balancing. Consider a client program that is running the following SQL once a 5 minutes:
select ...
from A
inner join B on ...
inner join C on ...
inner join D on ...
where the tables B, C and D data is changing all the time.Once load balancing is distributed more 'equally', the query above will arrive to node #1 and to node #2 more equally. It will cause more interconnect traffic, because Oracle RAC will need to synchronize requested blocks all the time, with much high rate.

i have a problem in my ODI 11g with the load into Oralce table of a fixed width file, i configured all the datasource in ODI and when i do view data i see all correct, the end of file is signed like "0D0A" but when i try my load interface i receive the message that my last field is more big than the one declared.
My file have an header of fields and the last field is a data-field of 2000 characters. I controlled and is really fixed the length cause is a COBOL file from a Mainframe. So it looks that ODI don't understand the end of that field and go ahead to the other, i just tryed to enlarge the limit but is always more big like if the file is shifting on the right.
Have i forgot some configuration in some place? The definition of the file present the end of file like Microsoft hexadecimal \u000D\u000A i try all the combination there but no way to avoid this problem.
