Oracle database upgrade from 10.2.0.1(32bit) to 10.2.0.4(64bit)

We are planning a Database Server upgrade. The current configuration is Red Hat Linux 4 (32Bit) and Oracle Database Enterprise 10.2.0.1 (32Bit). The proposed configuration is Red Hat Linux 5 (64Bit) and Oracle Database Enterprise 10.2.0.4 (64Bit).
No plans to change the middle-tier servers:
O/S- Windows 2003
OAS- Oracle Application Server Lite [Forms and Reports Service]- Version 10.1.2.0.2 .
No plans to change the development tools:
O/S- Windows XP SP2
Oracle Forms and Reports - (32Bit) Version 10.1.2.0.2 .
Has anyone encountered any gotchas/compatibility issues we should be aware of ?
Many thanks in advance for any advice.

You can check metalink doc
Changing between 32-bit and 64-bit Word Sizes
Doc ID: 62290.1
You'd better patch your 32 bit version to 10.2.0.4 first.

How big is the database ? How much downtime can you afford ? One option is to install 10.2.0.1 on the target, apply the 10.2.0.4 patch, create an empty instance on target, then export the database from the source and import into target.
Pl be aware that 10.2.0.1 thru 10.2.0.4 are on sustaining support and 10.2.0.5 is on extended support (if you have paid the extended support fees). Why not upgrade to 11gR2 ?

Oracle database upgrade from express edition to standard edition

We purchased Oracle database 11g to upgrade our current primavera oracle database express edition (10g).When we are trying to upgrade through DBUA it getting error message
Please provide us a proper advise to solve this issue.

11gR2 DBUA States "The CEP File does not provide the version directive" [ID 980693.1]
As noted by orafad, the easiest approach would be to perform a full export from 10gR2, install 11gR2 into a new ORACLE_HOME, create an empty 11gR2 database, then perform a full import into 11gR2. As also noted, you will have to follow any special directions related to Primavera.

Effects of Oracle Upgrade from 10.2.0.1(32bit) to 10.2.0.4(64bit)

Has anyone encountered any gotchas/compatibility issues we should be aware of ? Do we need to upgrade the middle-tier and Developer Tools at the same time ?
Many thanks in advance for any advice.

Our forms application runs against a databases runnung on lot of platforms, like
HP-UX, AIX, WinServer 2k3, RedHat, Suse,...32 and 64 bit from 9.2.0.8 up to 10.2.0.4...
our development database is a 9.2.0.6 Windows Server 2003 32bit, and I haven't faced any problems on other platforms after moving to them (except the platform specific database bugs).
Only thing I can remember would be, if you make use of the utl_file package on the database - I'm sure you know the dos2unix and unix2dos fileformat problem.
so if you don't plan to change the middle-tier servers you should not run into serious problems (except a recompile of your forms against the new database could be necessary) to my mind. No need for changing middle tier and developer toos.

Oracle Database upgrade from 10g R2 to 11g R2

Dear Oracle Experts,
Currently we I have three database on Oracle 10g(10.2.0.5) in same oracle home and want to upgrade only one database out of three.
Can you please advise if I can upgrade only one database instance(out of three database, same oracle home) and my two other database will run on 10g ? and can you please share steps also for the same
Best Regards
Farookh

Hi,
As Harry pointed out already, it's definitely possible and a good idea actually. By installing a new Oracle home you can easily revert back to the 10g one if you need to. It keeps everything separate and makes it cleaner.
I would recommend reading the Oracle docs. DK2010 has written them down here:
upgrade the database version 10.2.0.1.0
I made some notes on how to upgrade your database from 10g to 11g over on my site, they are the exact steps I used. It might help you to have a read through them but you should definitely read the Oracle docs and make sure everything you need for your environment is covered before upgrading. [url http://www.ora00600.com/wordpress/articles/oracle-10g-to-11g-upgrade-guide/]Here are my notes.
Hope that helps,
Rob

Testing while doing the database upgrade from 9.2.0.6 to 11.2.0.2 apps ?

Dear Experts,
Please note that we are in process of doing database upgrade from 9.2.0.6 to 11.2.0.2 ?
We have gone through the interoperablity note id for 11i 11gr2 ?
Step 1
upgrading the database from 9.2.0.6 to 9.2.0.8 ?
Step 2-
Upgrading the Forms patchset to 19 ?
Step-3
Applying the Rollup-6 patch ?
Step -4
Upgrading the database from 9.2.0.8 to 11.2.0.2 ?
We would like to know whether after each step do we have to do any kind of testing on the Oracle Application Instance and the database?
Please advise.
Regards
Mohammed.

We would like to know whether after each step do we have to do any kind of testing on the Oracle Application Instance and the database?There is no such a list. However, you can refer to the documents referenced in each task above and it should cover if any testing need to be done or not (for example, the Developer Patchset doc). For the rest of the docs you will have to do your regular testing (test the application/database and make sure it is working properly).
Also, make sure you review (Known issues on Top of 11i.ATG_PF.H. delta.6 (RUP6) - 5903765 [ID 459353.1]).
ATG RUP 7 is the latest 11i.ATG_PF patch.

Database upgradation from 10.2.0.3 to 11 R2

Hi
I am planning to upgrade my production database from 10.2.0.3 to 11.2. Before doing into production am testing it into our Test server in Linux OS. I got manual procedure of database upgradation from metalink. I installed Oracle 11g as software only into my test server. Now in step 2 , they describe as under
$ sqlplus '/ as sysdba'
SQL> spool upgrade_info.log
SQL> @utlu112i.sql
SQL> spool off
SQL>
My query is : I will run the script utlu112i.sql from which home ? Oracle 10g ? oracle 11g?
Please give me your wise suggestion.
Regards
Rabi

Hi Rabi,
First of all go to location (Oracle 11g) $ORACLE_HOME/rdbms/admin and
copy the utlu112i.sql script to /tmp directory.
Now login to 10g database “/ as sysdba” and startup the 10g database, then:
SQL> spool /tmp/upgrade_info.log
SQL> @/tmp/utlu112i.sql
SQL> spool off
Hope this will help you.

Database upgrade from 10.2.0.3.0 to 11.1.0.7

Hi All,
OS:linux 86x64 Red Hat linux
We would like to perform Database upgrade from 10.2.0.3.0 to 11.1.0.7.
I do have quick questions regarding the upgrade.
1. When we upgrade the Database to version 11, do we need to update the client also? What is Oracle recommendation?
2. Do we need to take any DB backup before the upgrade?
3. How will the OBIEE windows box ODBC connect to the upgraded 11 g instance? Will the version 10 driver work to connect to version 11 databases?
4. We have Informatica,DAC in the existing instance. Will the DB upgrade have any impact on them?
Could anyone please share their experience/thoughts on the above like the steps to perform the upgrade.
Thanks for your time!

I do have quick questions regarding the upgrade.
1. When we upgrade the Database to version 11, do we need to update the client also? What is Oracle recommendation?Just 11g upgrade will include all cient/Server tools on you Linux Box. On client side its recommended to upgrade client version 11.1.0.7.
Please refer MOS tech note:
*Oracle 10g Client Connecting To Oracle 11g Database Gets ORA-01017 invalid username/password [ID 888432.1]*
2. Do we need to take any DB backup before the upgrade?Yes, perform full cold backup of Database as well as 10G $ORACLE_HOME binaries including inventories.
3. How will the OBIEE windows box ODBC connect to the upgraded 11 g instance? Will the version 10 driver work to connect to version 11 databases?AFAIK, it should work. What is the version of OBIEE?
4. We have Informatica,DAC in the existing instance. Will the DB upgrade have any impact on them?Again AFAIK, there should not be any effect. I would recommend you to log a S.R and verify the same from support.

Oracle database upgrade

urrently we are running Oracle Server 7.3.4 Under Unix (SunOS5.7) with access
to a Sybase 12.5.0.1 via Oracle-Sybase Transparent Gateway 4.1.1.0.0. For the
web services, we use OAS 4.0.8.1. Our web applications are based on Javascript
and Oracle PL/SQL to generate HTML via the PL/SQL cartridge.
We plan to upgrade the Oracle database Server from 7.3.4 to Oracle 9.2.0.1.
Q1 - Will OAS4.0.8.1 and our applications continue to work with an Oracle 9.2
database or do we have to upgrade OAS4.0.8.1 to something like 9IAS?
Q2 - If we had to upgrade OAS4.0.8.1 to 9IAS:
a) what version?
b)will our applications (Javascript, HTML and PL/SQL-generated HTML) continue
to work uder 9IAS or do we have to make changes?
c)If we have to make changes to our application, what kind of chnges? Any
relevant articles from other users who have made the upgrade?
Please confirm that Oracle9.2 has a Gateway to Sybase 12.5.0.1 that will
support the features of 7.3.4 gateway (i.e it is downward compatible to 7.3.4
gateway).

You can do this without a problem.
(But make sure to be safe and backup your database.)

Oracle Database Upgradation 10g to 11g in HP unix

Oracle Database Upgradation 10g to 11g (standalone DB & ASM is implemented) in HP unix ?
Kindly furnish the good links and screen shot documents.
Edited by: user11937849 on Apr 9, 2012 4:04 AM

As part of the upgrade, you might research how new Oracle 11g features can help your system run better.
Your upgraded system can effectively start using extended statistics, a very powerful new 11g feature, immediately after the upgrade. I have a detailed blog post on how to do this with OEM - http://iiotzov.wordpress.com/2011/11/01/get-the-max-of-oracle-11gr2-right-from-the-start-create-relevant-extended-statistics-as-a-part-of-the-upgrade

Any Oracle database personal edition certified for Windows 7/32bit?

Is any Oracle database Personal edition certified for Windows 7/32bit? I spent an hour at least searching for this but no chance.
Thank you.

Currently, only 11gR2 and 10.2.0.5 are certified on Win 7 Professional or higher - Home versions are not supported.
