Downgrading Oracle database ( Version 9.2.0.8.0 to 9.2.0.6.0)

Hi All,
I am working as development Dbs. I had upgraded Oracle DB 9.2.0.1.0 to version 9.2.0.8.0 for some testing purpose in Windows XP(32bit). I didnt take the backup before applying patch. Now they want to downgrade the db to 9.2.0.6.0. How can i do that? Is there any patch for that? or Is there any patch for downgrading to 9.2.0.1.0? Please let me know a solution.
Thanks,
Manikandan

I meant if the COMPATIBLE parameter has been set to something greater than 9.2.0.1 or 9.2.0.6 (depending on which you want to downgrade to). If it is still 9.2.0.0 that is fine.
Check the patch documentation for rolling back the 9.2.0.8 patch.

Hi, I don't know how to find a specific security patch to apply to my Oracle database version to fix a vulnerability

Hi, I don't know how to find a specific security patch to apply to my Oracle database version 11.2.0.2.0 (on windows server 2003 32 bits) to fix the following vulnerability:
Risk: High
Application: oracle_tnslsnr
Port: 1521
Protocol: tcp
Synopsis:
It is possible to register with a remote Oracle TNS listener.
Description:
The remote Oracle TNS listener allows service registration from a remote host. An attacker can exploit this issue to divert data from a
legitimate database server or client to an attacker-specified system.
Successful exploits will allow the attacker to manipulate database instances, potentially facilitating man-in-the-middle, sessionhijacking,
or denial of service attacks on a legitimate database server.
Solution:
Apply the work-around in Oracle's advisory.
Thank you for your help

that sounds like the "tns poison" vulnerability. CVE 2012-1675 - Oracle Security Alert CVE-2012-1675

Is there any incompatibility in using different JDBC and Oracle database versions?

Hi everybody,
I hope you can answer me ASAP.
Which version of JDBC driver for Oracle could I use to access an Oracle database version 8.0.4.3.0 running on a SUN machine?
Is it necessary to use the specific driver concerning to that version or could we use the JDBC version 8.1.6?
If we decide to use JDBC 8.1.6 to work against the 8.0.4.3.0 database, will we find any incompatibility or problem?
Thanks.

I don't know the answer to your question, but while looking for something else, I found a table listing "requirements and compatibilities for oracle jdbc drivers" that might answer your question:
http://technet.oracle.com/docs/products/oracle8i/doc_library/817_doc/java.817/a83724/getsta1.htm#1008206
(My aologies if that URL gets broken apart by this posting software and you have to piece it together.)
Hope this helps.

Downgrading Oracle database 12.1.0 to 11R2

Hi everyone,
I'm very new to the oracle products and databases as well, so obviuosly my question might look like a bit simple for someone, but I do really need an answer to it.
I'm using OTN Developer Day VM, which comes with the preinstalled Oracle DB 12cR1. I'm wondering if its possible to dowgrade it to 11R2? Maybe in order to do the downgrade it must have been previously upgraded from 11R2 to 12cR1 ?

Your 'guess' is correct. You can only 'downgrade' IF you have previously 'upgraded' AND you have not modified the COMPATIBLE parameter.
See The Database Upgrade Guide
Downgrading Oracle Database to an Earlier Release
For supported releases of Oracle Database, you can downgrade a database to the release from which you last upgraded. For example, if you recently upgraded from release 11.2.0.4 to Oracle Database 12c, and you did not change the compatible initialization parameter to 12.1 or higher, then you can downgrade to release 11.2.0.4. If your Oracle Database 12c is release 12.1.0.2, and you did not change the compatible initialization parameter to 12.1.0.2, then you can downgrade to release 12.1.0.1 and so forth.

Ojdbc14.jar API and Oracle Database Version

Hi
Im using ojdbc14.jar for accessing an oracle 10G database.
Im trying to troubleshoot an exception -
java.sql.SQLException: Parameter Type Conflict
that seems to get thrown by the method -
OraclePreparedStatament.processCompletedBindRow
I have a couple of questions:
1. Is the documentation/source available for ojdbc14.jar in order that I can try and find out what this method is supposed to be doing?
2. Also, can anyone confirm if the jar Im using is the correct version of drivers for accessing a 10G database?
3. When I go to the JDBC support center at Oracle(http://www.oracle.com/technology/docs/tech/java/sqlj_jdbc/index.html) any support documentation/APIs refer only to the Oracle db version and dont mention Java versions. Im using ojdbc14.jar which I guess is for use with Java version 1.4 onwards - how does this relate to the Oracle database versions?
Thnaks very much in advance to anyone who can give me any suggestions on the above. This issue has stumped me for days now. Ive checked and double checked my code, and the Oracle Java types I have generated from the database, and they all seem to be fine.
Jon

unzip it, and look at the MANIFEST.MF file in META-INF
If you do not know the version, you can just download appropriate one from oracle site.

Oracle Database version support

My manager was asking about our plans to upgrade our current Oracle database version (10.1.0.4). We're currently humming along nicely, so I thought that I'd use an Obsolescence Policy as a guide to push us forward. I looked all over Metalink, but this was the only document I could find, which was a hyperlink from another Metalink document, which advertised it as a 10g Product RoadMap:
https://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=312470.1
It's not very helpful in that regard, plus it's from Nov 2007. Does anyone have a link to some more current documentation? I really appraciate your help.

Proxy User - Forms 11.1.2 and Oracle Database (version 10.1.0.5) ??

Hi,
we are migrating from Forms 6i to 11.1.2. Our database version is very old (Enterprise Edition, version 10.1.0.5) because this is the latest version of the DB that Forms 6i runs, and we will migrating to 11g in phases. So 6i and 11g will co-exists for a while (accesing the same DB).
I am trying to use proxy users feature to login to database.
So I did this:
- I created a user PROXY_USR to be the proxy user:
SQL> create user PROXY_USR identified by PROXY_PASW;*
- I grant create session for the user:
SQL> grant create session to PROXY_USR;*
- I changed the application users (eg APPUSER01), to connect via proxy user:
SQL> alter user APPUSER01 grant connect through PROXY_USR;*
The comand in Forms module to login is:
+LOGON('PROXY_USR[APPUSER01]','PROXY_PASW@DB01');+*
The logon built is being performed and the connection being made, without erros.
But when I verify in what user the application is logged on, the result is not
what was expected:
I did the follwing PL/SQL inside Form module:
begin*
select user into v_user_DB from dual;*
MESSAGE('User Connected: '||v_user_DB,ACKNOWLEDGE);*
exception*
when others then*
MESSAGE('ERR: '||SQLERRM,ACKNOWLEDGE);*
end;*
The result from this select, is PROXY_USR and not APPUSER01 (that would be the correct):
*>>Result: "User Connected: PROXY_USR"*
Some more commands that were also performed inside Forms module:
begin+
select sys_context('userenv','current_user') v_current_usr from dual+
MESSAGE('Current User: '||v_current_usr,ACKNOWLEDGE);+
exception+
when others then+
MESSAGE('ERR: '||SQLERRM,ACKNOWLEDGE);+
*>>Result: "User Connected: PROXY_USR"*
begin+
select sys_context('userenv','proxy_user') v_proxy_user from dual;+
MESSAGE('Current User: '||v_proxy_user,ACKNOWLEDGE);+
exception+
when others then+
MESSAGE('ERR: '||SQLERRM,ACKNOWLEDGE);+
*>>Result: "Proxy User: "*
OBS: when a connect via SQL*Plus, in a 11g database (Express), and run the commands above, the results are OK. The
APPUSER01 is returned.
Any ideas ?? I will open a SR in Metalink, but I think they will first request a database upgrade,
which is not feasible for us at the moment ...
Thanks in Advance.
Franco

Unfortunately besides trying on a certified combination (maybe use the Developer Database VM and import the required schemas for trial) and going through the documentation at http://docs.oracle.com/cd/E24269_01/doc.11120/e24477/sso.htm I can't offer more. I don't have a 10gR1 database anymore and also I don't have OID to play with.

OWB 10gR2 and 11gR2 integrate which with oracle database versions

I request a clear definite reply as I need to suggest the client to upgrade their production databases. I did try searching on the oracle sites, but did not get any sure answer.
Question:
The client has databases on 8i, 9i & 10g. Will OWB 10gR2 support these data sources?
If not, either I will have to ask clients to upgrate 8i & 9i to oracle 10g or have them upgrade the same and also have them upgrade to OWB 11gR2.
So, please confirm support of database versions for both OWB 10gR2 & OWB 11gR2.
Thanks much!

I already had the 'Release notes' link for both 10g and 11g which you provided.
The issue is when I launch the URL, I am taken to https://support.oracle.com/CSP/ui/flash.html.
Here I've to submit and register Sun Contract Number or Oracle Support Identifier. I don't have these details.
Isn't there a simple way to get the valid information on platform-specific requirements?
I mean this should be given easily on Oracle site.
Thanks much!

How to check the Oracle database version

Hi,
How can i check, what type of database am using and which version?
Can anyone help me to know?

I am not sure what exactly you mean by "what type of database am using " but you can try this:
select from v$version;*
This will give you detailed version number of the database components. You can also use
select from PRODUCT_COMPONENT_VERSION;*
to get various components of the DB with their version.

Which version of Oracle database is certified on Windows 2008 R2 ( 64-bit)

We have a Microsoft Windows 2008 R2 (64-bit) server.
I wanted to know which Oracle database version is 100% certified on the above OS.

Hi Sirini;
10.2.0.5 is supported - see MOS Doc 1061272.1 (Statement of Direction: Oracle Database 10g Release 2 Client (10.2.0.5) with Microsoft Windows 7 and Windows Server 2008 R2)Correct;
11gR2 is also supported - see MOS Doc 867040.1 (Statement of Direction: Oracle Database 11g Release 2 – Microsoft Windows 7 and Windows Server 2008 R2)There is a setup on this link:
Oracle Database 11g Release 2
(11.2.0.1.0)
Microsoft Windows (x64) File 1, File 2 (2GB) See All
I am little bit confused for this, as you mention note and also certification matrix says 11gr2 certfied with Win2008-64 bit. But there is no specific setup like win2008-64 bit, there is only Microsoft Windows (x64) setup
By the way for 10gR2 on win 2008 64 bit platform there are 2 setups. Those are:
Oracle Database 10g Release 2
Oracle Database 10g Release 2 (10.2.0.4) for Microsoft Windows Vista x64 and Microsoft Windows Server 2008 x64
Oracle Database 10g Release 2 (10.2.0.1.0) for Microsoft Windows (x64)
So i had issue for my client and oracle worker support me to use 10.2.0.4 for my issue, not second setup. So for 11gR2 could be work for Microsoft Windows (x64) but i am not sure %100 coz never tried before.
i appreciate, If someone share their experience to make installation 11gR2 on win2008-64 bit wiht Microsoft Windows (x64) setup
All those upper setups can be found at:
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
I do not believe 11gR1 is currently certified with Win 2008 R2.Please check below link:
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html

Which version of Oracle database is best for Windows 7 Home Premium?

Any input as to which version of Oracle database is best for Windows Home premium? Is there a major difference between the express edition and 10g itself as far as the interface/learning purposes goes?

EssbaseApprentice wrote:
Any input as to which version of Oracle database is best for Windows Home premium?That's easy to answer, none . No oracle database version was released for Home(Premimum) series. There are several blog posts/articles which do mention that they have installed oracle releases over Home(Premium) platforms but whether it would work or not, it would be just a lottery and help regarding troubleshooting would not be there.
Is there a major difference between the express edition and 10g itself as far as the interface/learning purposes goes?You mean 10g Express Edition and 10g Enterprise, Standard Editions? If yes, then there is indeed difference. The Express edition is more like a developer's playground with a good looking GUI even there to administer it. EE or SE are the production releases , meant for being used in a very busy, highly concurrent environments. There would be additional features like RAC and Dataguard that would come with EE and wont be there in the XE. So if you are learning to become a production DBA, you should right away use EE or SE IMO .

Can Oracle Grid support multiple database versions simultaneously?

Hi,
Quick question that likely has large ramifications - can a single Oracle Grid deployment host multiple Oracle database versions? e.g. from Version 7 through Version 11?
Thanks

Ok, you might be able to manage it but you will have to use a 3rd party clusterware for 9i rac. I was looking at ml note 220970.1 and it says
Oracle Clusterware (CRS) will not support a 9i RAC database so you will have to leave the current configuration in place. You can install Oracle Clusterware and RAC 10g into the same cluster. On Windows and Linux, you must run the 9i Cluster Manager for the 9i Database and the Oracle Clusterware for the 10g Database. When you install Oracle Clusterware, your 9i srvconfig file will be converted to the OCR. Both 9i RAC and 10g will use the OCR. Do not restart the 9i gsd after you have installed Oracle Clusterware. Remember to check certify for details of what vendor clusterware can be run with Oracle Clusterware.
For example on Solaris, your 9i RAC will be using Sun Cluster. You can install Oracle Clusterware and RAC 10g in the same cluster that is running Sun Cluster and 9i RAC.
