Accessing 64-bit Oracle from 32-bit ODBC

Hi
I am installing a software using 32-bit ODBC for connection to Oracle.
The server has been installed by our client and has the following specs:
- AMD Opteron Processor 280
- Windows server 2003 R2 Standard x64 Edition SP2
- Oracle 10g Release 10.2.0.3.0 - 64bit
- Both a 32-bit and a 64-bit client has been installed
Using the 32-bit ODBC administrator I can add the "Oracle in OraClient10g_home1" driver, but I can't find the right database, only lots of other databases our client has on other servers.
If I go to the 64-bit ODBC administrator I can find the right database and noting else, using the driver "Oracle in OraClient_home".
How can I get the 32-bit ODBC client to connect to the 64-bit database?
Regards
Leidulf

Hi
I did that, I entered the following into the tnsnames.ora, as this was how it was entered in the 64-bit client:
DKMVKK =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = krhsrvora02)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = DKMVKK)
Now I find this in the 32-bit ODBC administrator and the "Test Connection" is successful. And fails if I enter the wrong password, so I know it is correct.
But still I can't connect using the software that worked well on the previous server (32-bit), and using the same credentials and database name. I also have installed an independent SQL viewer that connects via ODBC, this does not work either, getting the ORA-12154.
I have also tried to change the HOST to the IP address with no luck.
The database and the client runs on the same machine.
What can be the problem?
Regards
Lediulf

32 bit oracle on 64 bit OS

Hi Everyone,
I just wanted to know whether is it possible to run 32 bit Oracle on 64 bit based Operating Systems.
Regards,
Bharath.

Hi Bharath;
I belive its beter way to download Linux (64-bit) stage and use this stage for installation.(Its not avaliable on edelivery,contact with your local oracle office or log SR for stage DVD)
If you want to test your stage on 64 bit please refer:

32 bit oracle in 64 bit OS and issues

Hi All,
Good morning, I installed windows 7 (64 bit) and installed oracle 10g 10.2.0.1.0 version. previously when I was used vista the ojdbc14.jar driver worked fine and able to access the DB using this driver. now I am getting the below error as:
=====

Difference between Oracle 10g 64 bit /Oracle 10g 32 Bit Windows

Hi all
We are using 10g Oracle 32 Bit windows as well as Oracle 10g 64 Windows at some installations.
Now we tested these two systems in our office for Testing purpose on two similar machines i.e
Intel i3 with 4 GB RAM. Database size approx 4GB
We had the feeling that :-
a) Oracle datafile Filesize limitation may be there in 32 Bit system but we saw that physically around 3.5 GB datafile size
is created in 32 Bit windows also
b) Data Fetching Speed -.We thought that data fetching speed would be higher in 64 Bit machine. But we proved to
be wrong. Our sample data had approx 7 Millions records (based on Client Live data for 3 years) total in around 20 transaction tables. Further there were other additional 100-150 tables but very smaller ones just master tables
We used the same client end machine and same Front end and same queries on both servers. To our surpriise - We got the almost similar results in terms of data fetching time in both the 32 Bit as well as 64 Bit windows with similar Oracle 10g 32 bit and Oracle 64 Bit respectively
Further we find that Anti Virus Programme which may be any say Symatentic or other - troubles much more in Windows 64 Bit environment as compared to Windows 32 Bit environment from settings point of view.
Kindly advise as to
a) Whether our above observations are correct
b) Now under what situations should we use Oracle 10g 64 Windows as compared to Oracle 10g 32 Bit windows

Installing 32 bit oracle on 64 bit windows 7

My oracle application works only with 32 bit oracle.Now I need to install the application on a 64 bit windows 7.I tried installing oracle 11g 32 bit database on this machine(64 bit windows 7).During the final stages,it gave an error that the listener service has not started.When I checked the Services status in Computer Management->Services,I found that the listener has already started.I closed the error message and continued with installation.The installation completed successfully.But when I login to sql plus with my oracle database(SYSTEM/SYSTEM@MYHOSTNAME),it is giving tns error ORA 12541-TNS NO LISTENER.I tried every possible ways like restarting the service, and deleting the listener and creating it again,but still it doesnt work.
If anyone has faced the same problem,please give me solution.
I cannot try installing 64 bit oracle because my application is not compatible with 64 bit oracle.

Edited by: 1001322 on Apr 20, 2013 7:23 AMIn addition to the other comments, you need to make the distinction between the oracle database and the oracle client.
the application interacts directly with the oracle client software. The application should not know or care about the word length of the database.

Can I install 32-bit Oracle on 64-bit os

Dear Gurus
I have installed windows-7 (64-bit) home basic OS.
Can I Install Oracle 10g (32-bit) software on above OS.
Thanking in advance
Sanjeev

Hello,
I have installed windows-7 (64-bit) home basic OS.
Can I Install Oracle 10g (32-bit) software on above OS.Why don't you try to install Oracle *10.2.0.5* for Windows 7 - 64 bit ?
I think it is safer and you could benefit fully of the 64 bit advantage (large SGA,...).
Anyway, you'll have to do this installation in 2 steps:
- Installation of Oracle 10.2.0.4
- Application of the Patch Set 10.2.0.5

Is it possible to use dataguard between 64 bit oracle and 32 bit oracle

primary db 64 bit oracle (10g r2)
standby db 32 bit oracle (10g r2)
is it possible to crate such a data protection solution with data guard that works
thanks for your reply

Hi,
Here is a related thread, with comments by the author of the Oracle Data Guard book:
http://dba.ipbhost.com/index.php?showtopic=1064
The main requirement is Oracle software and O/S should be exactly same on primary and standby hosts.
So you will need to install Linux 32 bit and same oracle software on both machines. I am not aware of any other modification that you will need.
The chipset can be different as long as the O/S is same on both the hosts as I/O calls are created by O/S and are not dependent on chipset.
Hope this help . . .

Bad cleardata performance on 64 bit (converted from 32 bit)

Hi All,
I've installed Essbase 64 bit (9.3.1) and copied an application directly from a 32 bit Essbase server (also 9.3.1).
All other components stayed the same.
Then i extracted all data and imported it into the new environment.
Calculating data takes a very long time in the new environment but the second time it goed a lot faster.
My issue is that when i execute a clear script it runs over 20 minutes. this was 2 minutes in the old environment.
All the settings are equal, servers are equal (except for the 32 64 bit difference), applications are equal etc.
Has anyone a suggestion why my clearscript is so slow?
The number of blocks are almost equal (due to some testing), the block size is equal but the .pag size differs a (16 vs 22 gb) and the .ind size differs a lot (1.5 vs 3.9 gb). the larger ones are the 64 bit environment.
I hope anyone has a clue where to look, because i'm lost.
Thanks,
Marc

cleardata is basically a read/write operation. I could be wrong but I think that performance is more closely tied to disk speed than bits or cpu. On the 32 bit system, was the data stored locally or on a sans? If it was local, were you using a raid array? How does the 64 bit system storage device differ?

Access UNIX-based Oracle from OS/390?

Hello. I'm having trouble finding information about the possibility of accessing an Oracle database (8.1.7) on AIX from an OS/390 mainframe. I have seen references to "Access Manager for CICS" but cannot locate it on the Oracle site. I have also looked at the Gateway information, but that seems focused on UNIX or AIX based Oracle looking at "files" or "databases" on other operating systems. Can someone clarify this for me?
thanks, Katie

I need help with the same question although I am coming at it from a different starting point.
I currently have a C++ application running in CICS & batch on OS/390 which is accessing an Oracle9i database also within the same OS/390.
I am considering moving the Oracle9i database from OS/390 to another OS (possibly Solaris). I understand that technically I can do this but I don't understand what software I need nor what the licencing situation is. I do not want to have Oracle9i database licenced for OS/390 but I obviously need have some sort of client software on OS/390.
Can someone tell me what is the client software product I need and how do I get it without needing to have a licence for the Oracle9i database for OS/390?
I have virtually no Oracle experience so excuse me if I am asking a silly question.
Thanks

64-bit vs 32-bit Oracle on Win2003

Background:
Ive been tasked to come up with the appropriate hardware/software solution for my company, an MMOLG (Massively Multiple On-Line Gaming) enterprise as it gets ramped up for two huge game releases. We use My SQL (4.x) for managing the Web Front-end, MS SQL 2000 Servers to manage the games, and Oracle to manage the billing application on the back-end. The billing application is also used for authentication (registration of new subscribers, credit card validations) and authorization (what games each subscriber can play, is their account up to date, etc.). We currently support our billing application using 32-bit Oracle (9.2.0.4) on 32-bit, clustered Win2k, using Failsafe (3.3.2) on MSCS (1.0). We have the first new game-to-be-released in Beta, and, to date, I have a similar setup except that the Oracle is 9.2.0.6, Failsafe is 3.3.3, and MSCS is 1.1. Originally, I was given to understand that each of the two new games were to be on separate Oracle instances, but now my management wants both games to be run from the same instance. Our Marketing team spit out the anticipated subscriber/subscription #s recently, and the size of the #s has given me pause I question whether or not our current system will be able to handle the # of logins (for authorization and authentication) during the so-called land-rush (the games 1st week/month of release) and that period of time immediately following an upgrade to the game (where huge #s of gamers rush to get back to playing). I also need to consider the peak # of logins during the heaviest play period times. The minimum # of gamer logins/hour I need to account for is 5-7k/hour, and the high end could be upwards of 30-45k/hour (for both games, post-upgrade case). To me, that number of logins/hour is asking a lot Windows 32-bit, perhaps the impossible.
What Ive done to date:
First I made sure that I understood what I can do with Windows, and then implemented a base test on the Beta environment by setting up Windows for VLM management. I have both the /PAE and /3GB switches enabled (I have 8GB of RAM, so the /3GB switch gets me the extra 1GB memory for shared_pool w/o being the hindrance it would be if I was using 16GB+), and I have the AWE tailored to 768MB (the minimum that, via trial and error, that I could bring Oracle up under). This has allowed me to have a shared_pool of 320MB, a java_pool and large_pool of 152MB (more on the large_pool later). To date, Ive sized the buffer_cache at 5000MB (just to prove that I could do it, and see the results). So SGA is 5362MB. Ive set the Aggregate PGA Target to 256MB.
Ive looked at 64-bit Oracle on 64-bit Win2003. 64-bit Oracle 9.2.0.7 is certified on Win2003 (Itanium only, no certification yet for the really spiffy EM64T chip set). If dedicated will not cut it for the max login load, I could consider Shared mode, knowing that I get some performance hit. Going to 64-bit Theres some test data out there (Larry Pedigo, of Performance Tuning Corp. had a nice white paper), but Ive found little else. This seems, at first blush, the best choice for a Windows shop, but who knows? Ive come across one gotcha to date, the Failsafe Manager is only 32-bit (while Failsafe is 64-bit, why Oracle did that, I do not know), so has to be installed on a separate home, on a separate 32-bit Windows machine. Ive gotten it from Oracle Support that 32-bit Oracle Client will connect w/o issue to the 64-bit Oracle server, so having the various 32-bit applications used (on separate 32-bit Win2k machines) connect to the database is not a problem.
Ive looked at putting 32-bit Oracle on a 64-bit Win2003, so if the initial load/stress tests fails (at 5-7k logins/hour) I could easily migrate Oracle to the 64-bit. From what Ive read, I would expect the 32-bit Oracle to be way too slow.
Ive looked at going to RAC as it would buy me twice the memory for the pools.
Im just starting to look at moving to Oracle on UNIX. I have yet to estimate the total cost for doing so (early guess-timate is $750k), and Id have to bring a Unix Sys Admin on-board. Up to now, Turbine has been 90% Windows, 10% Linux.
Questions for the group:
Has anyone out there had this problem to tackle?
Am I correct in thinking that Windows 32-bit would be swamped by the anticipated load?
Is anyone running 64-bit Oracle on 64-bit Win2003? If so, did you get what you expected with respect to performance? Any obstacles that you had to overcome?
Has anyone suggestions as to configuration/environment that would help me?
Any responses would be a God-send to this poor, beleaguered DBA. Thanks very much (in advance).

Wow, you have a big task at hand, and it looks very fun to build.
I say you should consider 10g r2, as it will soon (or maybe already released) run on the AMD Opteron and the EM64T now that windows 2003 is set up for these processors.
If you are not ready to go 10g, then I would seriously consider RAC for the 9i database.
and I wouldn't install 32 bit on 64bit machine. Its not supported and would give you less than desirable results

Oracle Client 64-bit and Oracle Client 32-bit on the same server

Hi,
I have a Windows 2008 server 64-bit with Oracle Client 64-bit and Oracle Client 32-bit installed on different directories (D:\Oracle and D:\Oracle32)
Is it possible to define for certain applications to use the TNSNAMES entry from the 64-bit Oracle Client
and for other applications to use the TNSNAMES entry from the 32-bit Oracle Client
Once I installed the Oracle Client 32-bit (Oracle Client 64-bit version was already installed) and restarted the server I performed a TNSPING and it defaulted to the Oracle Client 32-bit installation path
Thanks,
Barry

Hello,
When you install a new client on a server, it will update the PATH variable, and add the ORACLE_HOME\bin path to it, at the first place. That explains why the tnsping use the last installed ORACLE_HOME.
What you can do if you want only to change the default path to the tnsnames is to set the environment variable TNS_ADMIN to the path where the tnsnames you want to use is located. You can modify this variable in your application if you want to use another tnsnames.
If you want switch from 32 bits to 64 bits client, then you have to modify the PATH variable.
Hope this will help.
Best regards,
Sylvie

Switching back from 64 bit jvm process to 32 bit process

I have my customer, go-live on WLS 9.2 MP2 on Sun Solaris 10 on 64 -bit. We have faced several crashes related to different reasons. I had applied 3X4R patch from Weblogic as well. Now, because they are on production and server crash is unacceptable, I need to rollback to 32 bit version that is more stable. So, can anyone point me to documentation that states the steps to rolling back to 32 bit process from 64 bit. The concern here is to ensure that rolling back along with 64 bit patches from weblogic shouldn't create any new issue.
Please let me know.
Thanks.

First of all I am kind of surprised you've got a
speed gain of 20% using the 64 bit mode. I thought in
general there was not much speed gain and sometimes
even a loss of performance. My own reason for using
64bit mode is to be able to address more than 4gb of
memory.
Saying that, it seems you have the choice of either
run in 64bit mode and connect somehow (RMI???) to a
32bit JVM that will run your 32bit native libraries.
This seems to be a bit of a fragile and dingy
solution to me, which probably quickly loses any
speedgains you get from running in 64bit mode.
Or you just go for the 32bit mode all over, and hope
that some day in future your 3rd part libraries
become available in 64 bit mode.
Honestly, unless you're going to address lots of
memory, I think this last solution is the most viable
option.Good advice!

32 bit vs 64 bit oracle

Hi all,
I know 64 bit Processer has a an ablity to address larger memory than the 32 bit Processer.
My doubt is
1) What is the difference between 32 bit OS and a 64 bit OS.
2) What is the difference between 32 bit oracle and 64 bit oracle.
Can we install 32 bit on a 64 bit and vice versa.
Can someone throw some light on this.
