Multiple Oracle Home support 9i and 10g

I have 9i and 10g clients installed in separate oracle homes.
When I switch to 9i home my application is still using 10g OLE DB.
Is there any way that I can activate 9i OLEDB when 9i home is active and vice-versa?
Thanks

Have you gone through the chapter on troubleshooting replication problems in the Advanced Replication manual? In particular, the sections on DML changes not being asynchronously propagated and diagnosing problems with materialized views?

Multiple oracle homes on Windows and the "Path" environment variable

Hi There,
We have a windows 2003 database server that has few databases running oracle 10.2.0.3. We are installing oracle 11.2.0.1 on the box as well, and we were wondering, which binaries should come 1st in the path environment variable? and how does this effect the working oracle environment?
Going to the oracle home selector and swapping the 2 oracle homes around will have the same effect on the windows path variable - which will treat the 1st oracle home to be the default home - are there any general rules reg. multiple oracle homes on a server and the default home?
Should the earlier version of oracle always proceed the newer one (i.e. c:\oracle\product\10.2.0.3\bin;c:\oracle\product\11.2.0.1\bin) or should the newer oracle version comes 1st as newer oracle versions are usually backward compatible?
Your thoughts are highly appreciated.
Thanks

That isn't going to happen.
If you install 11.2 last it will appear in the PATH variable first
If you don't want that you need to Oracle Home Selector utility in the Installer to change it.
Obviously, as usual, all of this is documented.

Guidelines regarding directory structure for multiple Oracle homes on Unix!

Hi All,
Are there any guidelines published regarding directory structures that should be defined while using multiple Oracle homes on Unix/Linux box?
I am looking for guidelines regarding admin and oradata folders so that we dont accidentally mess up with the DB contents with a wrong Oracle home.
Its a development server with 8i and 10g. 11g might also get loaded on the same server in future.
Thanks in advance...
Regards

Thanks Maran.
I have already checked many installation guides before posting here. All of them mention about creating folders like /admin or /oradata on various mount points but none of the naming conventions really indicate whether it is a 8i database or a 10g database.
This is required when you are having multiple Oracle installations under /opt and databases are running from different mount points.

Shared cluster with multiple oracle homes

Hi All,
I got to build a shared oracle RAC cluster with multiple oracle home installation ( 10g R1 , 10g R2 , and 11g R1 & 2).
Of course the cluster ware will be version 11.2, but I wondered if there is any dependency on how I install oracle software? Do I have to start with 10g installation first? can I do 11g and then 10g?
Is there anything I should be aware of ?

I installed Oracle Application Server Enterprise which includes AS, Database, OID, Web Cache, SSO etc. and OSES on the same machine. Everything works except I think the windows version of OSES and AS need some patches so the crawler isn't working right. Everything does, however, install and run. I think Oracle develops everything in Linux (rumors of them now using Solaris) so on Linux everything should go smoother.

Regarding Multiple Oracle Homes

Hello,
Does all of the Oracle products support multiple homes ?
Can oracle 8i and oracle 8 products be kept in same oracle home ?
thanks

Hi Raj,
To answer your first question, No, not all of Oracle products
support multiple homes. All Oracle7 products and all release
8.0.3 are non-multiple Oracle home products. Oracle 8i lite
cannot support multiple oracle homes either.
In regards to your second question, no Oracle8i and and Oracle
8.0 products cannot be kept in the same Oracle home. Releases
prior to 8.1.3 cannot be installed in an Oracle home that was
created by a release of 8.1.3, 8.1.4 or 8.1.5.
Hope that helps,
Thanks & Regards,

Multiple oracle homes problem

Hi!
I have multiple oracle homes on my machine: Oracle9DB, DevsuiteHome_1 and now as I have just installed Oracle Discoverer 10g....BIToolsHome_1.
The problem is ever since I installed Discoverer, nothing is working......
Can anyone help?
Best regards,
Aparna

Dear Rod,
What I mean by nothing is working is I cannot connect to the dataases. I get 'No listener' error message.
Oracle Hone selector gives the following message:
The is only one Oracle Home defined on this machine and so this tool cannot be used to change your primary Oracle home.
I tried to start the listener service, however, it says:
Listener service started and then stopped.
Is there any solution to this problem?
Thanks and best regards,
Aparna

Multiple Oracle home

Hi ,
I have some doubt which needs to be cleared.
If I will install multiple oracle home like ORACLE_HOME=/u01/app/oracle/product/10.1.0/asm
ORACLE_HOME=/u01/app/oracle/product/9.2.0
ORACLE_HOME=/u01/app/oracle/product/10.2.0
ORACLE_HOME=/u01/app/oracle/product/crs
Now in this when I will set export ORACLE_HOME then which version will be picked up.
Is ORAENV isgoing to come into picture.
Please throw some light on it.

Asif KabirAsif,
Your advice to hard code the Oracle environment directly into the profile is poorly thought out. And a direct carry over of 'worst practices' unfortunately taught in some Oracle related classes.
The OP did correctly identify oraenv (as described in the "Administrator's Reference for UNIX-Based Operating Systems" at http://www.oracle.com/pls/db102/portal.portal_db?selected=4) as the preferred solution. Putting THAT into the profile (using ORAENV_ASK as described in the manual) is OK.
I'll leave you to figure out why the difference - I've posted many times about that in these forums.

Multiple Oracle Homes

Hi everybody,
I have Oracle 9i installed on my Windows machine.
I installed Oracle Developer Suite, but could not login due to TNS errors.
I have a little idea of what the problem is. We need to edit TNSNAMES.ORA file so that it could resolve the service name.
Can u please help me out in configuring Developer Suite to work properly?
Thanks.

Not quite sure why your title is Multiple Oracle Homes. Can you connect to SQLPLUS or any other product in the suite? Is it just Designer you are having hassles with? Do you have the database on the same machine and can you connect to that? If you are successful at connecting to SQLPLUS, then take a look at the tnsnames file in the Database network /admin directories.
There was a bug at one point where the tnsnames would fail if the network connect string was between 184 and 192 characters in length. You may be running into this. In which case if your tnsnames.ora contains
(CONNECT_DATA =(SID = <SID>), you can change this to use (CONNECT_DATA =(SERVICE_NAME= <SID>)

Oracle XE (Windows) Multiple Oracle Homes

I have a question in regards to Oracle Express Edition and how it maintains Oracle Home.
I currently have multiple Oracle Homes on my machine. In order for apps like SQL Developer or PLSQL Developer to see the correct TNSNAMES entries, I usually have to use the Home Selector from the Installation tools to properly obtain the correct tnsnames entries in the dropdowns.
Now, I'm a Linux DBA, not to keen on Oracle environments for Windows. But, when I installed Oracle Express Edition, none of my Applications SQL Developer or PLSQL Developer recognize the tnsnames entries for my environment. From the 9i Home Selector I see that it is in the correct environment I want it to use. But it seems Express has overriden somehow.
Can anyone lead me into the right direction to switch between my XE Environment to my 9i environments?
Thanks.

I did it too, but the beta over beta software is just too dangerous.. you never know what is crashing your system :)

Multiple oracle homes installation

i have installed oracle 9i database on single sever where 8i is residing using multiple oracle homes.After installation some folders and files related to 9i created in 8i home directory(eg:9i admin related folder create in 8i admin folder).but i dont want to create like that.is there any way to create all files related to 9i should reside on that 9i home directory only?

You didn't specified the OS.
Assume that your OS is Unix-like (Solaris, Linux) and your user is oracle.
The answer is very simple. Use different enviroments.
create in home directory (oracle user) two files:
1. .ora_8i
2. .ora_9i
All enviroment variables related for 8i database (ORACLE_BASE, ORACLE_HOME, ORACLE_SID, LD_LIBRARY_PATH etc.) are defined in .ora _8i and all variables for 9i are defined in .ora_9i.
Now, you want working with 8i so you need apply 8i enviroment. To do that simply execute following from shell ". ~/.ora_8i". Now you decided working with 9i so simply execute the ". ~/.ora_9i" from shell.
For installation use the same way. So before you run ./runInstaller load the apropriate enviroment.

Oracle Production Support Roles and Responsibilities

Hi,
I am currently working in Application Support from past 4 years and I have applied for a opening in Oracle Production Support environment and it is different from DBA.
So far i have never worked in Oracle Production Support so i am curious to know what exactly the roles and Responsibilities for this position.
What kind of issues comes and how to troubleshoot them?
I actually need to understand the nature of this job in detail and few interview questions that can be asked for this position.
Any kind of help will be appreciated.
Thanks in Advance,

In addition to Joe's questions regarding if you don't know the answer, then how do you know you want the job .......
Regarding job titles:
"When I use a word," Humpty Dumpty said in rather a scornful tone, "it means just what I choose it to mean -- neither more nor less."
(Lewis Carroll - Through the Looking Glass)
And so it is with job titles. Any given job title means only and exactly what the organization chooses it to mean -- "neither more nor less".
Even though we work in a technical industry, not every term you see has a universal, fixed, immutable, technical meaning. Not even close.
My first two jobs in IT were in shops that had exactly the same set of job titles for Programmers --
- Programmer/Analyst I
- Programmer/Analyst II
- Programmer/Analyst III
In one shop, the Programmer/Analyst III was the most junior of the three.
In the other, the Programmer/Analyst III was the most senior of the three.
So, you tell me, what is a "Programmer/Analyst III"? What is a "development DBA"? What is a "production support DBA"?

OraOps.dll and Multiple Oracle Homes

Hi All,
I am writing a simple Windows Forms client app that is trying to connect to an Oracle 8.1.7 database. I am having a problem connecting with ODP.NET. The error I get is as follows:
"An unhandled exception of type 'System.DllNotFoundException' occurred in oracle.dataaccess.dll
Additional information: Unable to load DLL (OraOps.dll)."
I have gone through these forums and tried everything that the various people suggested:
1) I have made sure that process can access the OraOps.dll file (In my program I opened the dll and read a couple of bytes out of it.)
2) I have installed the 8.1 client into a seperate home from ODP.NET (8 client and OraOLEDB is in D:\Oracle\Ora81, 9 client and ODP.NET is in D:\Oracle\Ora92) I intalled the 8 client first, then the 9 client with ODP.NET.
3) I have used the Oracle Home Selector to ensure that the Oracle 9 home is current.
4) I have checked the path that the process is using to ensure that the Oracle 9 home is first in the path, which it is.
Can anyone think of any other things that might cause this problem? I'm out of ideas. :-(
Jeremy

Absolutely...make sure that you use OUI to install the additional Oracle_Homes so that the inventory would be updated (instead of copying over from the existing OHs).
We have a cluster, wherein we have about 6 different ORACLE_HOMEs (whether it's good idea to have so many OHs is a totally different question though)...and it works fine and it well supported by Oracle. As such, you can both NON-RAC and RAC OHs as well, if you prefer.
Thanks

RAC and multiple Oracle Homes

Here is my issue: We have a central RAC cluster that I'm being asked to run on. It is a two node cluster. I would like to have my own Oracle homes on the boxes so that I have more control over the environment and management (like patching etc...). So on the box I would have a home for ASM, a home for Clusterware, and two database homes. Is this certified so that the databases running out of my home are clustered and managed by the Clusterware?
Thanks!
