Migrate 32-bit 10.2.0 to 64-bit 10.2.0

Hi,
Anyone did this before? I have a method which uses exp/imp utility to migrate and is successfully in my test environoment. But in production, the datasize is so large that I need more than 2 days to exp then imp to the 64-bit. Anyway that this can be done incrementally?
My new 64bit database name is the same as old 32bit database name, so for my previous method, I can up and down one database at a time.
But understand that database name and the server name can be changes also, will try it if there a incremental way of migrating from 32-bit to 64-bit.

I'm using windows 2003 for both database server.
Could not have Doc ID 403522.1. Try google in oracle.
Will try to understand this http://docs.oracle.com/cd/B19306_01/win.102/b15688/create.htm#NXQRF152. It mention about copy the configuration files? What are they?
Logfiles, Controlfiles, init.ora, tnsnames.ora, listener.ora? Is that all? My database installation is the basic, never change much configuration.
Sorry Not a DBA. Using datapump is it same as exp and imp? It works fine, just that it took too long to complete due to the size. I have around 50GB of datafiles.

MDT 2012 to Migrate from Windows 2003 32 Bit to Windows 2012 R2 64 Bit

I have used MDT for so long however only for client OS upgrade - XP to Windows 7/8.
We wish to use MDT to migrate from Windows 2003 32 Bit to Windows 2012 R2 64 Bit. All servers are virtual on HyperV or VMWare - plan is to use USMT hardlink Migration.
Is this supported? Has anyone used this for server migration?
Regards, Vik Singh "If this thread answered your question, please click on "Mark as Answer"

Thanks Keith for your reply.
Even is USMT does not work, we are ok. SMIGdeploy will be helpful.
Basically, want MDT to run some scripts on the Windows 2003 server, post which install Windows 2012 and join it to the existing domain with the same computer name.
Then hydration kit to help with the installation of features etc. Also, we would like to take a complete backup to a WIM before migrating.
I am sure this is workable.

Tuxedo Migration from Tuxedo 9.1 32 bit to Tuxedo 9.1 64 bit

Hi All,
Please tell me how to go for Tuxedo Migration from Tuxedo 9.1 32 bit to Tuxedo 9.1 64 bit. O.S. is IBM AIX 5.3 64 bit What are the prerequisite, and how to go for that. Please tell hoe to go for the same. Please mail at [email protected]

Ravi,
You will need to download 64-bit AIX binaries for Tuxedo 9.1.
Since 64-bit object files and libraries cannot be combined with 32-bit object files and libraries in the same executable, you will also need to obtain 64-bit versions of any database or other third party software that is linked with your Tuxedo application. (If you are using Oracle database, 64-bit and 32-bit support is combined in a single download, and you will just need to change $ORACLE_HOME/lib32 to $ORACLE_HOME/lib in your makefiles.)
Once this is done, you will need to rebuild your Tuxedo servers, clients, and TMS processes.
If you use buildclient and buildserver to compile all files, then you may not need to change anything else. If you call the compiler directly to compile source files into object files, then you will need to add additional flags for 64-bit compilation. If your makefiles are well-coded, you might just need to change CFLAGS in one place. Look at the output of "buildclient -v" for a simple client on the 32-bit system and on the 64-bit system to see which additional flags might be needed.
When your application is compiled in 64-bit mode, you just need to test it out to ensure that the application does not have any implicit 32-bit dependencies such as assuming that a "long" is the same as an "int".

Moving a 32 bit Oracle 9i database to 64 bit on a different server

Hello,
We have a 24 GB database with Oracle 9.2.0.7 (32 bit). As the hardware of this server is getting obsolete, it is planned to move this instance to another server, which has 64 bit Oracle software of same version (9.2.0.7). In this scenario what is the best way to move the instance?
Is it only the full export from 32 bit server and import into 64 bit server(after creating the instance there)?
Since this is a 24 GB database, and target server is 8 gb of ram, any pointers on how long the import process can take?
There is a documentation to change word size, I can run utlirp.sql as suggested here:
http://www.orafaq.com/forum/?t=rview&goto=258668#msg_258668
But I have some doubts as I mentioned in that post. Can you please share your suggestions?
Thanks,
Nirav

Hi
Is there some document or steps to follow when creating the instance on the new server The database move is easy, and here is one way to move the schema, fast:
http://www.dba-oracle.com/oracle_tips_db_copy.htm
And then, you just run the script to change the wordsize for 64-bit:
Also, after your migration, watch out for common performance issues:
http://www.dba-oracle.com/t_bad_poor_performance_upgrade_migration_32_64_bit.htm
Also, note that Oracle has changed the optimizer costing model from "IO" to CPU" in 10g, and shops that combine an upgrade to 64-bit servers with a 10g migration may want to look at changing the new default for _optimizer_cost_model.
Going 64-bit means that you can now allocate very large RAM data buffers and increase your shared_pool_size above two gigabytes. However, it is important to remember that there are downsides to having a super-large db_cache_size. While direct access to data is done with hashing, there are times when the database must examine all of the blocks in the RAM cache. These types of database may not always benefit from an upgrade to a 64 bit server:
Systems with high Invalidations: Whenever a program issues a truncated table, uses temporary tables, or runs a large data purge, Oracle must sweep all of the blocks in the db_cache_size to remove dirty blocks. This can cause excessive overhead for system with a db_cache_size greater than 10 gigabytes.
High Update Systems: The database writer (DBWR) process must sweep all of the blocks in db_cache_size when performing an asynchronous write. Having a huge db_cache_size can cause excessive work for the database writer. Some shops dedicate a separate, smaller data buffer (of a different blocksize) for high-update objects.
RAC systems: Oracle RAC and Grid does not perform optimally with super-large data buffer RAM, as available in 64-bit systems. You may experience high cross-instance calls when using a large db_cache_size in multiple RAC instances. This inter-instance "pinging" can cause excessive overhead, and that is why RAC DBA's try to segregate RAC instances to access specific areas of the database. This is why Oracle 10g grid server blades generally contain only 4-gig RAM.
Hope this helps. . .

Since Forms 6 was never certified on Vista, I will assume you don't care about using Oracle Support. If that's the case, getting Forms 6 to work on Win 7 would likey require similar steps as you took to getting it to work on Vista.
At minimum, you would need to do the following:
1. Start with Forms/Reports 6.0.8.11 (6i Release 2)
2. Install the latest (last) patch (#17), bring the version to 6.0.8.26
3. It may be necessary to relax or disable Windows UAC
4. To run the executables, you have to right click on them and select Run As Administrator in order for them to work properly.
THE ABOVE IS NOT A SUPPORTED CONFIGURATION
Forms 6.x was desupported years ago. If you have not already begun to do so, you should probably be working on a migration plan in order to get you to a supported version. The latest version is 11.1.1.3, so you are far behind. All versions newer than 6.x are entirely web based. This means that you will no longer be able to use the Forms runtime on the client machines. Client machines will require an Oracle certified browser and JRE in order to run Forms. Certification information for Fusion Middleware 11 (includes Forms 11) can be found here:
http://www.oracle.com/technetwork/middleware/downloads/fmw-11gr1certmatrix.xls

Install Oracle 10.2.0.1 (32 bit) on Windows Server 2012 (64 bit)

Hello
Can I install Migrate my database 10.2.0.1 (32 bit) to Windows Server 2012 (64 bit).
I would like to install Oracle 10.2 server (32 bit ) on Windows Server 2012 (64 bit).

It is not a supported combination (see the Certification tab in MOS) - so things may or may not work as advertised. Is there a reason to continue to use a desupported version of the database ?

Replacing a 32 bit primary server with a 64 bit

I have two zcm11 servers. Our first server is a 32 bit and the second is 64 bit.
The 32 bit server was our first server and the 64 bit was added later.
I would like to remove the 32 bit server and install a new ZCM server, preferably with sp3.
I'm not sure of the steps involved here or the best way to go.
Is this difficult? Can my second (ZCM2) take over and I just pull out zcm1?
Is this the way to go?
https://www.novell.com/documentation...a/bj1yh9t.html

Just restoring the CERTS and DB is not really the proper way to recover,
though I do understand sometimes you must do what you must do.
The disaster recovery guide has steps that cover everything to backup
and restore. One key is that many config files exist that contain
paths. If you restore to a server that has installed ZCM to a different
path, there will be lots of cleanup that needs to be done in those files.
Since the Default Path is ProgramFile, which varies on 32bit and 64bit
boxes it gets tricky. If you had installed to a Non-Default path such
as D:\ZENworks, then it really would not matter on the 32bit vs 64bit.

Cannot uninstall 32 bit iTunes on Windows 7 64 Bit

Just got a new computer with Windows 7 64 bit. I transferred my programs over included the 32 bit version of iTunes. I want to install the 64 bit version, but when I run the 64 bit installer it gives me an error message that I have the 32 bit version and that I need to download the 64 bit version. I tried to uninstall iTunes from the Control Panel, but I get the same error. Can anyone help?

Scraping a 32-bit iTunes out of a 64-bit system can be tricky.
Perhaps let's first try this. Download and install the Windows Installer CleanUp utility from Microsoft:
http://support.microsoft.com/kb/290301
Now run the utility ("Start > All programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove".
Quit out of CleanUp, restart the PC, and try another iTunes (64-bit) install. Does it go through properly this time?
(If you get another error message on the reinstall attempt, let us know what that one says too.)

Hi BIRam,
Based on the current information, the issue may be caused by the factor that the SQL Server Agent Service Account doesn’t have access to the MySQL server. Try to create a SQL Server Agent Proxy account that has sufficient permission on the MySQL server.
In addition, also pay attention to the package protection level setting.

I have Windows 7, but have only 32-bit ?...need 64-bit. How do I install 64-bit version? Am not computer savvy?

I am not computer savvy and do not understand 32-bit version of what they are talking about; nor, do I know how to update to the 64-bit version. Are they referring to my web browser, or what? And, how do I update to the 64-bit version. Do I have to buy different software, or what? Someone, please help me with this. It happened again today when I wanted to update my Java plug-in. Said I was using 32-bit, so would have to install both 32 and 64-bit version. I am confused.

Firefox is currently only as a 32 bit application available.<br />
A 64 bit Firefox version requires all plugins to be 64 bit as well and not many plugins have a 64 bit version.
You shouldn't have any problem with running that 32 bit Firefox version on a 64 bit Windows platform.

How do i download itunes on one computer (64-bit) for a different computer(32-bit)?

How do I download itunes on one computer (64-bit) for a different computer (32-bit)? The download page automatically detects my computer as 64-bit, but I want to download the installer for a different computer that is 32-bit.

I ended up changing the user agent reported by my web browser to fool the website into thinking I was using a different web browser. On Google Chrome, press Ctrl-Shift-I to open the Developer Tools, then click the gear in the lower-right corner of the window. Check "Override User Agent" then select "Internet Explorer 7" from the drop-down.
Once upon a time, you could download the 32-bit version of iTunes from http://www.apple.com/itunes/affiliates/download/, but the download link hasn't been updated recently and points to an old version of iTunes.
If, like me, you think Apple should provide a link to the 32-bit version from the main download page, I would recommend giving Apple your feedback.
