Oracle 8i compatibility with Oracle 10g server

We are upgrading our server from Oracle 8.1.7.4 to 10.2.0.4. I have many users who would be connecting to 10g server using 8i client. Is 8i client compatible to 10g server ?

You should have no problems except some operations may not work properly.
I think you should refer to this document:
Upgrade Guide at http://download.oracle.com/docs/cd/B19306_01/server.102/b14238/toc.htm
It does mention 8i to work properly.
Oracle itself does not certify that that upgrading from 8i to 10g would work the same. They expect upgrading from 8i to 9i to work, and 9i to 10g.
Connecting to the DB will work seamlessly , it is other things you might want to worry about. Such as Java thin clients (version for 8i) to connect to 10g that may be at fault, so you'd have to upgrade those as well.
Same goes for .NET libraries if you use that.

Oracle 11g compatibility with oracle 10g and 9i?

Hi All
I have some queries on 11g compatibility.
Is oracle 11g client compatible with oracle 10g client which is already installed on desktop?
If yes any changes to be done and where?
Is oracle 11g compatible with oracle 10g/9i on the same server where 10g/9i are installed?
Regards

Thanks Justin Thats right ...
Problem elaboration is as follows
We currently have an application which requires oracle 10g(10.2.0.3) client to connect to database from user desktops. As
part of new application development the oracle 11g clients need to be installed on all the user deskotps.
The complete application software along with oracle client 11g has to be roled out on these desktop as part of
implementaion of new application besides the existing application(The application software is packaged along with oracle
10g client).
We would like to understand if there is any software provided by oracle using which we can switch between different oracle
versions while accessing the respective applications simultaneously. Also are there any known bugs/issues in running
oracle 10g client and oracle 11g client together on the same user desktops with different oracle homes?

How does Oracle client communicate with a database server

Looking to idenify how Oracle Database Client for OpenVMS communicates with database server and whether the protocol used is secure. Realize that it is using whatever the configured network protocol is (ie. tcpip) but is languauge it uses ( ie. SQL, etc..) secured/encrypted and if not what steps can be taken to encypt

I have installed oracle client 10g on client pc for getting connection to Oracle databse 10g (runng on windows server) usng ODBC through SAGE ACC PAC (ERP). Working fine earlier. Now all of a suddent user starts complaining about database connection. When checked his pc registry values. Two values of ODBC keys are reset to null. Those are DSN and DRIVER values. How come this values reset to null? What is causing this to reset?Nothing in this has anything to do with the sever. You need to check what the client did on his machine that caused registry to get modified?
How does oracle ODBC works with Oracle database? Need to know all the steps involved?The connectoin from any client is initiated by a client process. This client process is supposed to get a server process to do his work. So if this is done, the client can work now with oracle . Please see the concepts guide for the gory details of the entire process.

Advantages and Disadvantages of Using Oracle 7 Client with Oracle 9 Server

Hello,
I was wondering what are the advanatges of using Oracle 7 client with Oracle 9 Server versus using Oracle 9 Client with Oracle 9 server.

Some years ago I used 7.3 Client with 9i DB, and I don't remember of particular problems, but I'm speaking of Sql*Plus only. Are there specific problems ?
Of course the best thing is to install one 9i Client (did you already do it ?) : if there are same problems, then that's not compatibility issue.
And what are advantages of using 9 Client with 9 server other than 7 is no longer supported.You're sure you won't have compatibility problems.

Does Oracle OLAP comes with Oracle Database 10g ?

1.Does Oracle OLAP comes with Oracle Database 10g or do we need seperate software to have this ?.
2.If I create a Cube with Analytic work space manager the cube is going to be stored in the Database ( meaning the in the table space where OLAP is Stored).
3. What is the difference between Analtyic work space manager and discoverer For Olap.
Help is higly appreciated ..
Thanks, Prasad

One thing to point out : The OLAP option is a costed database option, so while this is automatically installed and part of your database you do have to purchase additional licenses to use this feature. You will need to check with your Oracle account manager to see if you are actually licensed to use this feature.
If you have existing 9i OLAP cubes these can be quickly and easily migrated to 10g OLAP and the documentation explains how to do this. However, there are many new features that are part of 10g OLAP that will improve the performance of your data model that will not be enabled as part of a migration process. Based on my experiences it would be quicker and easier (depending on the size of your existing 9i OLAP cubes) to consider rebuilding your data model using these new 10g features. You should be able to export all the dimensions to XML templates from 9i OLAP and import the templates into the 10g schema and reload your dimensions.
For the cubes you will probably want to consider using partitioning, composites and compression to provide maximum flexibility and performance for your new data model. There is more information on these features within the OLAP documentation and in the many whitepapers and presentations on the OLAP home page on OTN.
For moving data from SQL Server to 10g OLAP much depends on the nature of the data transfer. If it is a one-off bulk data load then you could consider using the normal MS command line tools to dump the data out and transfer it to Oracle. Alternatively, you could consider using Oracle Data Integrator to manage the extraction of the SQL Server data and the data load process into Oracle 10g relational tables. If you decide to use Data Integrator this will require additional licenses.
If you can extract the data from SQL Server to flat files you can use Oracle Warehouse Builder (basic ETL is free as part of the 10g database license) to load that flat file data via external tables. Warehouse Builder can also be used to define your OLAP data model (think of Warehouse Builder as a more powerful version of Analytic Workspace Manager) and provides tools to load the data directly into your OLAP dimensions and cubes. You can get more information on managing OLAP data models with Warehouse Builder the Warehouse Builder home page on OTN.
There are no facilities to modify Discoverer Viewer to add customisations. You can add company logos, modify certain colors and/or hide certain features but it is not possible to add additional features. You may want to consider using BI Beans to provide this type of environment. BI Beans is the development framework used to create Discoverer Viewer. You can create customised JSP pages that look identical to Discoverer Viewer pages with the added benefit of providing your own specific features. You can get more information on the BI Beans home page on OTN.

Query on Driver Compatibility with Oracle 9i & Oracle 11g

Technical query on Driver Compatibility with Oracle 9i & Oracle 11g of our client scenario
1. There are 2 databases, FCDB and FCR DB. Both the databases are running on Oracle 9i. FCDB Application present is using the same version of JDBC driver (classes12.jar) to communicate with FCDB Local and FCR Host Database. And it is JDK 1.4 compliant.
2. We require upgrading the FCDB alone to 11g Release 1 and FCR DB with same Oracle 9i.
3. In this case, if the application is using the same version of JDBC driver (classes12.jar) to communicate with FCDB Local and FCR Host Database, will there be any issues.
4. Need to check if there is any issues related to the classes12.jar with 11g Release 1 DB whether oracle will extend their support to us and how and when they can they provide it.
5. If there are any issues, can that be resolved by Oracle Support?

Hi Boris,
Looks like you have not run the post upgrade script for 10.1.3.4.
You need to install SOA 10.1.3.4 Basic Installation. Then start following : http://download.oracle.com/docs/cd/E12524_01/core.1013/e13058/weblogic.htm#BHCIIBFB
You basically, first install 10.1.3.4 basic SOA install, Apply the Opatch 7337034 (HOTPLUG: SOASUITE 10.1.3.4 ON WEBLOGIC 9.2 - CHANGES FOR HOTPLUGGABILITY). Install WLS 9.2 MP3.
Now, Download the Oracle SOA Suite 10.1.3.4 WebLogic Server 9.2 : patch : 7490612.
Then , Modify the following mandatory installation properties in the Weblogic_SOA10134_Base\SOADomain.properties file as per the documentation above.
Cheers

Does ORACLE functions work with Oracle Database 10G

Hi,
I am wondering if ORACLE functions work with Oracle Database 10G or is it mandatory to use OCI functions?
Thanks in advance!

I was able to run a simple query with ora_* functions using 10g on Windows.
The Oracle OCI calls used by PHP's ora extension still exist in the Oracle 10g libraries
But I cannot recommend this obsolete extension.
