Oracle Homes (Mess up folders)

Hi i have do a little readup about installing oracle database of different versions. People say that they must be installed in 2 different oracle homes.
I am running Oracle 9i and Oracle 10g now.
and i put both of them in the C:\oracle\products
9i in C:\oracle\products\9i
10g in C:\oracle\products\10g
however inside C:\oracle, there seems to be files that belong to oracle 9i database including c:\oracle\admin and c:\oracle\oradata . Now i feel that if this goes on, my oracle folder will get a littlebit more and more mess up. so am i doing the right thing ?
1) what is oracle home ? i read it on the web and it say oracle home is the whole set of oracle objects/programs/tools that a oracle version belongs to. does that means that oracle10g R1 is different from oracle 10g R2 ? and must be put in different oracle homes ?
does it means that for different oracle home, i must put them in different folder inside c:\oracle. ..
like
c:\oracle\ora9iHome
c:\oracle\ora10gR1Home
c:\oracle\ora10gR2Home
am i right ? pls advise

What you can have is several versions sharing ORACLE_BASE, probably c:\oracle\products in your case. Below that, the version is specified, and that is where an ORACLE_HOME starts on your PC. You have three ORACLE_HOMEs because you installed three different versions, and yes, you cannot mix homes anymore (there were a few products/versions where you could, but those have long since expired).

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.

Forms installation problem - how do I create a new default Oracle home?

I am new to Oracle so please forgive my utter ignorance. My impression of Oracle because of how an installation
has to be done is taking a nosedive. I thought Microsoft was bad with all the re-booting but the explanation that I
read in Anubhav Seth's post about installing Dev 6i before 8i and the suggestion (not a requirement) to format the
harddisk and reinstall Windows just leaves me with my jaw hanging open. I'm having a little trouble swallowing that
one.
Here's my situation... I'm running 8i at home and I am using it for the Oracle courses that I am taking at a local
university. So 8i with its SQL*Plus has been all I have needed to date. Now we have a project to do that involves forms.
So I go to the OTN page for downloads and downloaded file 6irel2nt.exe which is 264 MB in size. This file, I assume,
has forms in it -- what else I don't know because things are not explained all that well on the web site or I don't know
where to look (which implies poor organization of the web pages).
I run the 6irel2nt.exe file and end up with 11,128 new files on my computer. That's nice. I run the setup file and a step or
two into it it complains that my 'Ora81' home is already being used and that I need to install it into another Oracle Home.
Now I'm trying to find out how I create another Oracle Home. I perform a search in GOOGLE on "creat default Oracle
home" and basically get nowhere. My $50+ "Oracle 8i A Beginner's Guide" from Oracle Press mentions Oracle Home
on one page (pg. 170) but is completely useless in this case. My $184 worth of Oracle University manuals (which
are really PowerPoint slides) is useless too. My next step will be to comb through the FAQs. All this because I cannot
believe that I have to totally uninstall one product to get another to install and then reinstall the first one. That is INSANE!
If I have gone way off track please feel free to blast me but if this is true then all I can say is that the folks at Oracle need
a lesson in KISS (Keep It Simple Stupid)! Computers and computer software are supposed to make our lives simpler
not complicate the holy hell out of them. I'll get off my soapbox now. Sorry about the whining.

I ended up uninstalling 8i and then I installed Dev 6i (Forms) and then I reinstalled 8i. I had some problems
installing Dev 6i because of this error "path.vrf(86): Unbound variable 'path_too_long_prompt'". Right after this error
appears I get a dialog that states, "The Oracle Installer cannot update the system path variable to %new_path%
because it is too long. Please restrict your system path to 127 characters and make sure D:\Oracle\OraWin95\bin
is included in your path."
The path D:\Oracle\OraWin95 was what I set up for this installation.
What I did to work around this problem was this...
(1) Go to Start - Accessories - System Tools - System Information.
(2) Click on the Tools menu
(3) Select System Configuration Utility
(4) Select the Autoexec.bat tab
(5) I added D:\Oracle\OraWin95\bin to my PATH variable and unchecked the checkbox next to one of the several
lines that I have that build my PATH variable. (I have several PATH lines that simply add a path to the system
variable %path%). After the installation is complete you can go back and turn back on the paths that you had disabled.
After installing 8i I did have a problem connecting to the database. I got this error:
Error: ORA-01034 Oracle not available
I believe this happened because I had forgotten to turn back on some of my PATH information that I mentioned
earlier. After checking one of my PATH variables and rebooting, this problem disappeared.
When reinstalling 8i and when the installation asks for an SID and you enter the SID you had used in the original
installation you may get a notice that says the SID already exists. I think this happens because the uninstall does not
clean up the registry totally, so I entered a different one. Later on, after the installation has been completed and you
are connecting to your database, you will be prompted to select an SID -- just make sure that you select the SID from
the latest installation.
I should've mentioned first that in preparing for this whole ridiculous exercise I created a directory under my Oracle
directory that I was going to use as the new 'Oracle home.' So I guess that's all one has to do to create a new Oracle
home -- just have another directory ready to install 'stuff' into.
All in all, this a pretty asinine exercise. Oracle really needs to fix this mess. I honestly thought Microsoft was bad but
this takes the cake. I wonder if SQL Server is this screwed up.

ODI installation out of Oracle home

Hi,
I have to install Oracle Data Integrator on a development server where EPM 11.1.2 is already installed. I encounter the following error after setting the install folder (I leave it to default: D:\Oracle\Middleware\EPMSystem11R1):
OUI-10044: The selected Oracle Home location already contains an Oracle Home
or APPL_TOP created while running a different OS
I've done some research and found [ that post|http://gerardnico.com/wiki/database/oracle/oui-10044], which didn't help much.
Basically my ODI file shiphomeproperties.xml shows an OS id 233, which is good.
The problem might be that I have two Oracle folders under C:/. One under "Program Files(x86)" that shows an OS id of 912 and another under "Program Files" which shows an OS id 233. Now I'm guessing that the Oracle installer looks into the wrong file...
Now I might have a workaround, if I change the default install folder, for example to Oracle1, I can access the next step.
My question is to know if it's ok to installl ODI in another Oracle home, is it ok to have two oracle home ?
thanks for your help.

Clean up Oracle Home (11.1.0.6)

Hi,
One of my Oracle Home (11.1.0.6) on HPUnix IA64, is 10GB.
As far as I understand, an Oracle Home should not be more than 5-6GB isnt it? Correct me if I am wrong.
And also please let me know how to free up the space in the Oracle Home. Which directory should I search for cleaning up the space in the Oracle Home?
Thanks!

Thanks!From my experience:
1. Too many trace files in background_dump_dest (as you have 11g, you should check DIAGNOSTIC_DEST)
2. Too many audit files
3. Core dump files/folders in above destinations or in $ORACLE_HOME/dbs

Running multiple instances from same oracle home

Hi Gurus,
I am preparing for OCA 11g examination. I had a question about running multiple instances from same oracle home. While reading the book I came across a statement about database control which says "If there are several database instances running off the same Oracle home, then each will have its own Database Control instance".
Now I assume that this statement implies multiple instances accessing the same physical database (which as per my knowledge can happen only in case of a RAC).
I am not able to understand how exactly can you have multiple database instances in a single oracle home. I have installed Oracle 11g on my computer whose oracle home is +"D:\oracle\product\10.2.0\db_1"+; now this directory houses all the binaries (executables and folders like admin,bin, etc) for the oracle instance that I have installed (the instance name is ocp1). Now if I am to install or create another Oracle Instance (say ocp2) in the same home, wont there be a conflict of binaries of the two instances in the same home ?
Basically,it makes sense if db_1 folder is further split into multiple folders, one for each instance (for example, one for ocp1 & one for ocp2); each of these folders will then contain the binary files, libraries,etc for its own instance; but, this is not the case, here db_1 houses all the binaries directly under it ...
The other question which stems from the statement I mentioned above is that if having multiple instances running from same oracle home accessing the same physical database, can this arrangement be called RAC at all; or does RAC dictate that you cannot have multiple instances that are accessing the same database have to be installed on physically separate machines and so you cannot have two RAC instances (accessing same physical database) installed on the same computer ??
I hope my questions are not too much confusing ... !!
Cheers,
Sudripta

Hello,
"If there are several database instances running off the same Oracle home, then each will have its own Database Control instance".This is true, and also means each instance will have its separate database (i.e. dbf files etc.) & separate DB Control. Usually in this case you create several instances on the same node.
Now I assume that this statement implies multiple instances accessing the same physical database (which as per my knowledge can happen only in case of a RAC).You are correct about RAC where several instances (usually running on separate nodes) access the RAC.
More info:
1 Oracle Home - 1 Database - 1 SID is possible.
1 Oracle Home - Many Databases - Many SID is possible.
1 Oracle HOme - 1 Database - Multiple SID is possible and this is called RAC.

Oracle developer suite installed under a different Oracle Home

I have Oracle 10g r2 installed on a RHAS4 server.
I installed Oracle developer suite 10.1 on this server. In the installation procedures, there are specific instructions to not install it under the ORACLE_HOME for an existing database installation.
Oracle was already installed under /usr/lib/oracle (don't ask me why, I didn't do it).
I installed oracle developer suite under /oracle/dev. If I set ORACLE_HOME to /usr/lib/oracle, proc responds with:
Symbol `kpccapCTarr' has different size in shared object, consider re-linking
PCC-F-NOERRFILE, unable to open error message file, facility PR2
If I set ORACLE_HOME to /oracle/dev, it works correctly.
This appears to require me to switch my oracle home setting each time I switch between using Pro*C and sqlplus. This in very inconvenient. I have worked on many, many systems in the past which had one ORACLE_HOME for both the RDBMS and the development tools.
Is this a new constraint introduced by Oracle? Where does this restriction come from?
Is there something I don't understand and have I installed the developer suite incorrectly?

It looks to me this is a mess; i have installed oracle 10g on rhas4 and it didn't install under that folder. I'd suggest to run oui/run installer and show what are the oracle_homes found there; maybe you should reinstall it in the proper locations, under different accounts, etc.

Installing & Uninstalling Oracle Home

We have installed multiple Oracle Versions in same machine like below.
Ora9i_db_Hom
- Oracle 9i Database 9.2.0.2.0
- Oracle Universal Installer 10.1.0.2.0
- Oracle 9iR2 Patch Set 9.2.0.5
- Oracle 9iR2 Patch Set 9.2.0.8
OraDb11g_home1
- Oracle Database 11g 11.2.0.1.0
Ora_9205_Home
- Oracle 9i Database 9.2.0.2.0
- Oracle Universal Installer 10.1.0.2.0
- Oracle 9iR2 Patch Set 9.2.0.5
- Oracle 9iR2 Patch Set 9.2.0.8
OraDB10g_Home1
- Oracle Database 10g 10.2.0.1.0
- Oracle Database 10g Release 2 Patch Set 3 10.2.0.4.0
The reason for this installation was to upgrade 9i & 10g Database to 11g. We upgraded all the database to 11g and its running on 11g now. Now I would like to remove the old versions (9i & 10g).
My Question is,
1. If I Remove 9i Oracle Home using OUI, will it effect any of the database that is running on the machine?
2. For some reason if I want to install 9i again after uninstalling, will that be a problem?
Edited by: ManoRangasamy on Nov 30, 2010 9:42 AM

Well, the obvious answer about databases being affected has to include any 9i database if the 9i home/software is removed. Other than that, no, assuming none of the other databases have any dependencies related to 9i (e.g., database links).
If you think you may have to reinstall 9i, don't remove it in the first place. If you can afford the disk space to keep it, what is the harm in keeping it on the system? You really don't want the brain damage of messing around with older versions of OUI.

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.

Locating Oracle Home

This is more of a Best Practices question
Environment:
Oracle 8i on Solaris
Clariion storage array disks
10G physical Memory
To ensure high availability and decrease the coupling with the server, we have place the oracle home not on the local scsi disks but on the storage array connected by a fiber channel.
1.Does oracle need to read binaries from Oracle home directory on a ongoing basis or is it just read and cached when the database is started?
2.Should we consider housing the udump,bdump and cdump folders out of the Oracle Home to avoid any contention?
3. Is it always recommended to have the Oracle Home on the local drive of the server?

Referencing your questions
3- You can place the Oracle home anywhere you want it on your disk farm. The Oracle binaries are not hit that heavily.
2- I would move bdump, cdump, and udump to their own file system to prevent their filling Oracle home with dump files.
1- Mostly the binaries are read on startup but some DLL objects may be read when needed.
Most of the Oracle related activity will be on the database datafiles. The Oracle binary is relatively unimportant from an IO point of view.

Need of Two Oracle Home in R12

I am a newbie apps dba and was going through the oracle documentation. Where I learnt that in r12 there are two ORACLE_HOME 10.2.0 and 10.3.0. I tried to research regarding the same but couldn't find anything conclusive enough that would clear my fundamentals regarding the need for having 2 ORACLE_HOME. Of what I have understood , 10.2.0 is Developer Home which hosts the Apache, forms server etc and 10.3.0 hosts the JAVA/html server etc. Is my understanding correct regarding the same ? and what is the use and advantage of having two Oracle Homes? Do explain me in laymen terms as I am still a newbie!

BhaviSavla;
I guess you dint understand what I have said!!! I HAVE ALREADY READ THAT THOUSAND TIMES!!! Please think double&triple time while you are talking wiht Hussein Sawwan about EBS related questions. I am sure about Hussein Sawwan understand your question as he understand other questions and already he has been answered your question(If you have ability to understand what you read)
I strongly suggest you about TO BE KIND-RESPECT with forum users which are trying to help other people here.
And I am still not able to understand the actual advantage of having TWO ORACLE_HOME...After read something, If you still understand than dont blame forum users. Choose easy way... Rise SR!
Kindly do not post just to increase your number of posts on this forum!! If you cannot help me in anyway with this, kindly do not post!If you dont follow OTN forum site consistently than DO NOT MAKE COMMENT about people here If the topic is Hussein Sawwan.
I must remind you something... He has more than 50k post wiht 51k points which mean he made post here like your_post_count*1500times... Wiht other words, his each post equal to 1 point, which mean his each post has meaning which are helpful!
Do you have capability to calculate how mch time he spend here?
Dont thing so!
Moderator, I belive this question is already answered If the poster read notes! Please close or lock this thread!

Multiple oracle home installation

I am going to install oracle 11g2 on hpux server. The server already has 10g on it and the plan is to run both for sometimes.
Unfortunately, IUnfortunately, I don’t have prior experience installing multi-homed oracle software and I
need help on how to supply the oracle home directory name to the installer:
Do I have to supply the installation (OUI) with the oracle home directory: i.e
Exiting oracle home: /u00/app/oracle/product/10.2.0/db_1
For the new oracle home: /u00/app/oracle/product/11.2.0/db_2
Is this correct?
thank you,
Lou

What I did was create two profiles. My OS is similar, but NOT the same
My default is Oracle 11.
However I need a way to go back between Oracle Homes so I created an "o10g.profile" and a "o11g.profile"
o10g.profile
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
export ORACLE_BASE=/u01/app/oracle
unset ORACLE_HOME
export ORACLE_HOME=/u01/app/oracle/product/10.2.0

export ORA_OCI_NO_OPTIMIZED_FETCH=1
ORA_OCI_NO_OPTIMIZED_FETCH=1; export ORA_OCI_NO_OPTIMIZED_FETCH
export ORACLE_SID=STANDBY
export ORACLE_TERM=xterm
#export TNS_ADMIN= Set if sqlnet.ora, tnsnames.ora, etc. are not in $ORACLE_HOME/network/admin
export NLS_LANG=AMERICAN;
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH
# Set shell search paths
unset PATH
PATH=/usr/sbin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin; export PATH
export PATH=$PATH:$ORACLE_HOME/bin
#CLASSPATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlibNotice the unset ORACLE_HOME at the top, this is key. Also the unset PATH.
Now compare it to my o11g.profile file
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
export ORACLE_BASE=/u01/app/oracle
unset ORACLE_HOME
export ORACLE_HOME=/u01/app/oracle/product/11.2.0

export ORACLE_SID=PRIMARY
export ORACLE_TERM=xterm
#export TNS_ADMIN= Set if sqlnet.ora, tnsnames.ora, etc. are not in $ORACLE_HOME/network/admin
export NLS_LANG=AMERICAN;
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH

#CLASSPATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlibIts probably a great idea to review the document Srini refers to. However this is a short and sweet example. In my case I can issue a
source o10g.profileAnd be on Oracle 10. So to install the other version I created the profile for it and then then used it to switch to that ENV for the install.

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.

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.
