Upgrade Oracle from Oracle9i to Oracle 10g

Hi,
We will be having a project on upgrading the existing version of Oracle 9i to 10g.
Our application uses Java as the front end and Oracle as the backend.
So if anyone has done similar kind of Oracle upgrade from 9i to 10g, could you please tell us –
1) What are the steps involved in upgrading Java drivers (if any).
2) Also any other changes to be made on Java front.
Thank you,
DNN

I have the following queries:
1. Does any third-party application running on Oracle 9i Enterprise Edition need to be changed when we migrate from 9i database server to Oracle Standard One Edition 10g?
2. What's the difference between Oracle 9i Enterprise and Oracle Standard One Edition 10g?
3. We are using Oracle 9i Database on a server with Oracle 9i Client on nodes with third-party software. When we upgrade our 9i server to 10g, can we connect to 10g from our existing 9i client nodes? Slowly we can upgrade all 9i clients to 10g clients. Otherwise, all the machines in the company need to be changed to 10g client and work will suffer a lot, as this upgrade job cannot be done in a single day.

Possible Upgrade Path from ALUI 6.1 to Webcenter Interaction 10gR3

We are in the planning stages of an upgrade. Currently we are using ALUI 6.1 MP1 and wish to upgrade to WebCenter Interaction 10gR3. I am wonderng if the upgrade path is ALUI 6.1 MP1 --> ALUI 6.5 MP1 --> WCI 10gr3?
Is it possible to go directly from ALUI 6.1 MP1 to WCI 10gR3?

I was told that I could install from 6.1 to 10G. Which I did...
what you need to remember is to run the upgrade scripts to your database from 6.1 to 6.5, and then upgrade scrip from 6.5 to 10G. thats all, but you do not have to run the install for 6.5, just go directly to 10G.

How to upgrade from OCS 904 to 10g but not upgrading Oracle Files

Hi All,
We have installed OCS 904 from where we only are using:
- Portal
- Oracle Files
Our idea is to upgrade this installation to OCS 10g but keeping the same version of Oracle Files (we don't want to migrate to content services for the moment).
Is this possible? or if we want to keep Oracle Files we need to do a fresh install of OCS 10g in another location?
Thanks in advance,
Harvey

>I want to upgrade it from RHEL 6 TO RHEL 7 and from ORACLE 11G TO ORACLE 12C. I wonder if anyone could suggest the best url for for upgrading accordingly.
which metric measures best? Fewest keystrokes?
BTW - you are actually doing 2 upgrades. You are upgrading OS & you are upgrading Oracle version.
So you can either over then up or up then over.
How much down down time is available?
How much risk do you want to include?

SQLException:Connection timed out- after upgrading from oracle9i to 10g

Hi,
Recently we upgraded from oracle 9i to 10g.
We are using Oracle JDBC Driver version - 10.1.0.5.0 .
In the application, when RMI server starts, the connectionpool (developed using stack) will be filled with 10 instances of fresh connections.
After keeping the RMI server idle for some time ( >24 hours ) , the first transaction sent to the Database (using the connection instance popped out from stack(connectionpool) ) terminates with following exception and from the second transaction onwards everything works normally.

If am connecting to oracle9i(with Oracle JDBC Driver version - 9.0.2.0.0) ,everything works fine.
Can anyone help me out to solve this issue?

I attempted several upgrades and we decided it was better to implement the content under 10g fresh rather than attempt an upgrade.
After 3-5 attempts through patching non of them provided us with re-produceable steps and we had different errors each time - mind you this was a few months back after initial release of upgrade patches.

Thanks in Advance.You can use manual or using exp/imp can upgrade your database.
1.Take cold backup from 9i database.
2.Install 10g software and create need directories and restore cold backup
3.Startup database with upgrade option
sqlplus "/as sysdba"
startup upgrade pfile='pfile_location'
@$ORACLE_HOME/rdbms/admin/catupgrd.sql;
shutdown immediate;

Need help in writing test cases while upgradin oracle from 10g to 11g

hi all
I want to write test cases for ugrading oracle 10g to 11g i have some idea but want your input.and at the same time some people taking upgrade testing as to ensure that everything works after the upgrade - stremas, jobs, procedures.but i think as 11g is backward compatible all the things should work properly.If not then how can we write a test cases for that,your help is most welcome.
Thanks in advance

Hi;
Please see below notes which could give you some idea to create your test case. By the way if your components are certified wiht 11g so there should be any bad issue for your upgrade

Upgrade from Oracle Web Server to Oracle 9ias(9.0.4).

Hi,
I want to upgrade Oracle Web Server to Oracle 9ias(9.0.4).
Can anybody please tell me what are the pre-requisites for this and where can I find the documentation for this?
Regards - Sachin

Hi Sachin,
If you are indeed running Oracle (Web) Application Server 4.0.8.2 or similar, the best way to upgrade will depend on what applications that you are running.
There are upgrade guides from Oracle (Web) Application Server to Oracle Internet Application Server 1.0 as well as guides from 8i to 9i and 10g avaliable under documentation here at OTN.
The latest version avaliable right now is 10.1.2.0.2. It might make sense to go to 10.1.2.0.2 than to 9.0.4 at this time.

Mathias
