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:
=====

Actually I am facing this issue due to 64 bit. its not OS specific.Do you mean you had this working on 32 bit Windows 7?
many of the production support systems are running on 64 bit processors.My point was not related to 32 bit or 64 bit but running Oracle software on an unsupported platform.

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:

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

Hope this help.

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

Solaris 7 to 8 Upgrade with Oracle 8.1.5 (opinions and issues to note)

Hi all,
Think the subject says it all..
I have a Solaris 7 server running on Sparc E250 with Oracle8.1.5 on it. It shows that it s a 64bit system when booting up and it uses normal Solaris filesystem setup (no RAID on it) .
If I were to upgrade it to Solaris 8, what are the issues I need to take note.
Thanks.
Ld

This could be a big headache....but if there is a need to upgrade your OS from 7 to 8
then you should be ready for a good backup plan....meaning, if something goes wrong at any
point in the process, you could easily revert back to your old system environment.
If I were the one to do this, I will do the following.
1) I will make use of mirroring. It will be good if you could do it for the entire filesystem
of your OS and your DB.
2) Once I have a mirror, I will simply detach the other mirror and do my upgrade.
Anything goes wrong, I will simply make use of the other mirror to have my old system back.
When you upgrade your OS from 7 to 8, I had seen lots of problem where it could not complete the
process. And the reason is the size of the Filesystem for Solaris 8 specially the root requires
a big size as to any previous version. i usually just install from scratch. But the problem is if
your filesystem for the OS and Applications like your DB are crossing each other then you may have
to rebuilt your Applications too. Unless you had partition them such that they are totally separated.
When you had succesfully installed your Solaris 8, then your next headache is to make sure
all your applicatiions including your DB will be running fine with the new OS. Usually they
would not as they may need to be patched. So that means you have to check the Oracle websites
as for what are the patches needed to make your Oracle runs properlly in the new OS.
Most important is your backup plan, which is your mirrored-disk of your running environment.
Also you have to make a Plan of everything. Doing this will really take a lot of time.
Good luck. I have done this before.....I'm pretty sure you could do it.
just remember , your back-up plan should always be available anytime.

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

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

32-bit Oracle8i to 64-bit oracle 9i

Hi,
We have a 32-bit Oracle 8i running on AIX4.3,we are planning to shift to a new physical server which is supposed to run AIX5.3 & 64-bit oracle 9i.In this case if I do a database export from the current live machine( 32-bit Oracle 8i running on AIX4.3) whether i can import it on 64-bit oracle 9i @ AIX5.3 without any issues?
Regards,
Cherry

I think yes. I would like to listen from others.
While exporting use 8i exp utility. While Importing use 9i imp utility.

32 bit compiled Java Program not connecting to 64 bit Oracle 11g

Hi,
I am using one java program to connect to Oracle 11g (64 bit version) using Oracle10g 32 bit client libraries using OCI calls. Below is the program. If I compile it using 64 bit Oracle 10g libraries ($ORACLE_HOME/lib and $ORACLE_HOME/rdbms/lib) , it perfectly connects to Oracle11g but when i compile it using $ORACLE_HOME/lib32 and $ORACLE_HOME/rdbms/lib32, it hangs and keeps trying and takes 100% cpu usage. it does nothing. Please suggest what is going wrong in the environment.

The ojdbc14.jar file is for use with Java 1.4 VMs.
Are you still using Java 1.4? If so, why?
For Oracle 11g you should be using the latest JDBC jar file (ojdbc6.jar) and the latest version of Java 1.6.
You are not only using an old JDBC driver and Java version but are also trying to mix 32 bit and 64 bit operations.
I suggest you start using recommended practices and update your Java and JDBC versions and select EITHER 32 bit or 64 bit operations.
See the Official JDBC FAQ for the details on the support available for various combinations of Oracle DB, Java and the JDBC drivers:

Tutorial Oracle DB 64 bit

Hi,
Where I can find tutorial installing 64 bit Oracle DB 11g on Windows Server 2008 R2 64bit and then connecting to Data Mover using 32 bit Oracle client ?

Installing 64bit and 32bit Oracle is same. The downloaded software is different.
All in one box ?
1. Install Oracle database server 64bit in oracle home 1, create the db from there
2. Install Oracle client 32bit in oracle home 2, update the tnsnames.ora there to be able to connect on the database running from within the oracle home 1
3. During Peopletools installation, when prompted, give the 32bit client bin folder for AppDesigner and DMS.

64 bit oracle direver issue in SQLBindCol?

I have an issue with SQLBindCol when I connect to oracle though 64 bit 11gr1 oracle odbc driver.
SQLINTEGER nKey;
SQLLEN nInd = 0;
status = SQLBindCol(stmt, 1, SQL_C_SLONG, &nKey, 0, &nInd);
status = SQLFetch(stmt);
after call SQLFetch, I always get Run-Time Check Failure #2 - Stack around the variable 'nKey' was corrupted
I also noticed the return value of nInd is 8, but it should be 4. If I change the SQLINTEGER nKey to __int64 nKey, the error go away.
Why Oracle Odbc Driver required 8 byte for SQL_C_SLONG, and other odbc driver work fine(MSSQL, Sybase)? Is there a bug in Oracle odbc driver, or 64 bit oracle odbc dirver not follow the ODBC specification?
Thanks

You don't need reference on x64 version. You can add reference on x86 version. If you would like to run project from VS then you need x86 version Oracle Client because VS is x86 application.
Both ODAC DLL (x86 and x64) has same signature. If you build project with "any cpu" option then right version ODP.NET is used at the runtime.

SSIS Oracle 11g 64 bit client upgrade Issue

After the oracle client upgrade from 10g to 11g, the ssis jobs are getting failed for the BadImageFormatException. Attempt to load Oracle client libraries threw This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.
But the same package with same system requirements and same sql agent configuration is wroking fine in DIT. Please find below the system configuration in both environment.
DIT
Oracle Client - Oracle 11g 64 bit , Microsoft SQL Server - 32 and 64bit, Windows machine - 64 bt SP4, In job there is no configuration in command line to run in 32 bit mode since we are using the are using the .Net Provider/OracleClient Data Provider connection manager to the database .
UAT :

In UAT, Everything looks as DIT but the job is not working fine in DIT.
I have gone through all the thread related to 32 64 bit, .Net Oracle client provide but i haven't found any solution for this problem.
Can you please tell me the missed out configuration in DIT and UAT? the exact problem for this issue ? what is the oracle components required for this connection? Its urgent.
What is missing in the oracle end?
Thanks

Diffrence in running oracle on 32 bit OS and 64 bit OS ?

Hi ,
I am new to oracle , i would like to know what's the diffrence running oracle under 32 bit OS and 64 bit OS

i would like to know what's the diffrence running oracle under 32 bit OS and 64 bit OSWhat type of differences are you looking for? Basic one being you run 32 bit version of Oracle under 32 bit OS and 64 bit version under 64 bit OS.
Other being the availability of addressable memory in 32 and 64 bit versions (but that is more of an hardware level issue).
