Assalamu alaikum Asif,
Since you have an operating system which does not know that you have oracle Installed, try the following:
- provide the "Oracle_home\bin" directory in your path so that it detects where the Oracle executables are residing.
- Also ensure to set the Oracle home and Oracle base.
- In windows since it uses the services to run certain application you will have to create a service for oracle using the "oradim" utility eg: oradim -new -sid orcl
- Before you start opening the sqlplus from cmd, first ensure you set you Oracle_sid, Oracle_home and then invoke sqlplus
Try the above and let me know if you find any difficulties in proceeding with this or you can also try the below option
- You can simply take a backup of the database via RMAN or logical backup via export and then use these to restore the database after reinstalling the Oracle software.

Link Oracle Home in Windows?

Hi All,
How do you make a link of Oracle Home in Windows?
In unix, I can do it as
# ln -s /u01/app/oracle/product/11.2.0/dbhome_1 /OracleHomeThanks a lot,

Even i never come across with that situation, I tried to dig on it. i found something for you, read this
On Windows, Oracle Database DLLs form part of the executable at run time and are therefore smaller. DLLs can be shared between multiple executables. Relinking by the user is not supported, but executable images can be modified using ORASTACK.
Modifying executable images on Windows reduces the chances of running out of virtual memory when using a large SGA or when supporting thousands of connections. However, Oracle recommends doing this only under the guidance of Oracle Support Services.

Linking Oracle Workflow with Oracle Applications

Hi All,
I have created a workflow file using Oracle Workflow Builder but dont know how to link it with Oracle Applications.
Can someone help me by giving the step by step process involved to link the wft file with my oracle application.
Thanx in Advance.
K.K.Prasadh

Hi
Things ar not clear .
If it is new workflow , then you will have to modify the application to use the
workflow. I do not think you want to do that. You need to set up attributes
of the workflow and create process using Oracle flow routine.
If you want modify the existing workflow , You need the open the existing
workflow and modify without changing the itemtype. If you create a new process
in this item type the you have to assign the process in Account window
in Oracle application.
I hope this will help you.

Hi All,
I am facing the same issue again after installed the oracle linux 4.5.
My Source database is 9i it is running in oracle linux 4.4, So i couldn't register my oracle home in the ORACLE Linux 4.5.I have to downgrade my Oracle linux from 4.5 to 4.4.
I sourced the below steps from google,
Hello everybody! I have a problem with my server and I want to check that it isn't a software problem. So, firstly I want to downgrade from 4.5b6 to 4.4. Just to point out, I have a Plus license. So, to do the downgrade, Do I just have to change the following files? : bzimage
bzroot Nothing else? Thank you so much.
It is that easy.
You can rename the existing two files so you can put them back into place as bzroot and bzimage if the experiment does not result in an improvement. I do that on my system. bzroot would become bzroot.456 and bzimage woud be re-named as bzimage.456
As an alternative, you could add the 4.4.2 files as bzroot.442 and bzimage.442 and then add three lines to your syslinux.cfg file. They would result in additional menu choices when you next boot to allow you to choose to boot on either the older or the current version.
A copy of my syslinux.cfg file is below. You can see I can elect to boot on on almost any of the recent releases, as I've kept re-named copies of each release in turn on my flash drive.
(All the lines I added are in "blue", the three lines for 4.4.2 you would need to add are in "bold blue.". It would require you to put the 4.4.2 files in place renamed as bzroot.442 and bzimage.442)
The only thing you need to be aware of if you re-name the files as I've done is the names must be legal names under DOS on a FAT file-system. Therefore, the names must be at most 8 characters long with a three character "extension"
bzimage.456 is legal, bzimage.45b6 is not. (because it has a 4 character extension)

How can we clone the Oracle database in new Oracle Home

Hi,
I would like to clone oracle database into new oracle home. How can we set it using OEM.
I am using 10g grid control. Target db is on solaris
Thanks
Naveen

after logging into target database, under maintenance tab, data movement header; ther is "clone database" option. When you click on it; you'll see :
Clone Database uses RMAN to duplicate a database from:
-- An open database in ARCHIVELOG mode, or
-- An open database in NOARCHIVELOG mode (restart required), or
-- A saved working directory from previous cloning
Clone Database performs the following operations:
-- Backup each database file and store it in a working directory
-- Transfer each backup file from source to destination host
-- Restore each backup file to existing destination Oracle Home
-- Recover the cloned database with saved archived log files
-- Open the cloned database with resetlogs
It seems to be for cloning to a different host, but i guess you can chose the same host for source and destination. (I've never used cloning on em by the way :))
But firstly, you should create a new oracle home, you can simply copy your oracle home with a new name (cp -R /oracle/app/oracle/product/10.2.0 /oracle/app/oracle/product/10.2.0.new) or make a new installation.
I suggest you to do this cloning with CLI. You should take a full backup with RMAN, copy the oracle home, create a new initNEWSID.ora file and nomount the database, restore (or simply copy) controlfiles, restore database (with set newname commands), recover database, open resetlogs.

Oracle Connectivity with MS SQL Server. ORA-00972: identifier is too long

I have linked Oracle Database with MS SQL Server using HS and DB Link.
DB Link Script:

Remove / Reuse Oracle Home

An installation of Oracle 10gR2 failed in silent mode. So, I ran the deinstallation script and now want to rerun the installation but I'm getting the error: "Oracle Home with name already exists at location...Please specify another location for Oracle Home." The directory where we want to install the software is empty. What is it that we are missing in order to install the software in the directory? How do we remove the Oracle_home that was not successfully used in the failed installation?
The server is a solaris server. I know how to accomplish this on a Windows platform server.
Thanks.

There are no eroneous entries in the oratab file. At this point we are just looking to install the 10gr2 software. Here is the error that we are receiving:
SEVERE:OUI-10136:An Oracle Home with name OraDbHome2 already exists at location /u01/oracle/product/10.2.0. Please specify another location for Oracle Home.
All we are looking to do is remove any references to the directory where we want to install the software and re-run the installation.

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.

Deregister oracle-home

I'm trying to clone ebs 12.2.3 appsTier into an existing Environment (document 1383621.1). Adcfgclone Fails because Oracle-Homes are registered in Oracle Inventory. When I try to deregister the Oracle-Homes with " runInstaller -detachHome" I get the error message that detacheHome is not a valid Option.
I have no FMW_HOME in the target Environment, so I used runInstaller from $ORACLE_HOME/oui/bin.
How to deregister the Oracle-Homes?

Please see (R12.2 : How To Create, Update or Rebuild The Central Inventory For Oracle Applications E-Business Suite ? (Doc ID 1588609.1)), Procedure 2: Detaching an Oracle Home using the Oracle Universal Installer
If you still get the same error, please post the command you are running along with the complete error message.
Thanks,

No Oracle Home Selector in 10g?

I finished installing 10.1.0.2 DB on Win XP Professional a short while ago. This machine already had 8.1.7 client, 9.0.1 client, and 9.2.0 db installed.
I went to Oracle Home Selector under Oracle Installation Products on my start menu and saw only previous ORACLE_HOMEs are available.
I checked my PATH from a command prompt and find the new 10g ORACLE_HOME/bin is first in my PATH. That's fine, for now but when I want to change it I'll have to change it manually. Ok, I can do that. It's annoying but workable. But I can't expect the "normal" end user to deal with this. What's up Oracle?

Here is a fix ... I don't think its recommended !
1. run regedit
2. Find ORACLE - ALL HOMES (Under HKEY_LOCAL_MACHINE -> SOFTWARE)
There will be ID0 and ID1 etc ., (If you have previous version of Oracle).
3. Keep your mouse on ALL HOMES -> Right click -> New -> Key
Name it ID2 or ID3 (depends on how many Oracle Homes you have)
4. Now you have ID2 or ID3 ready ...
Keep your mouse on ID2 or ID3 -> Right Click -> String Value
Enter NAME ... string your actual OraHome92 or OraHome10g
Another String value -> Enter NLS_LANG and set the value
another String value -> Enter PATH and set the exact path
Go to your Oracle Home Selector ... you will find the new Oracle Home with its path !
Thanks

Using patch plans for 12.1.0.2 target oracle home fails with 'PREREQ_MESG: Unable to get the version of OPatch'

We are attempting to use patch plan to apply PSU and one-offs to a new 12.1.0.2 database oracle home. Our EM version is 12.1.0.4.
We are experiencing the same issue described in ''Bug 20271609 : Unable to get the version of OPatch". This bug is closed as 'duplicate bug to filer' but we do not appear to have visibility into what patch/bug fixes the issue.
Description from the above mentioned bug is our same issue. We do not have this issue when we use patch plans against an 11.2.x oracle_home target. It is unique to 12.1.0.2 oracle_home target.
Description from the bug:
The Plan failed in step "Run Prerequisite Checks" with the following errors:
PREREQ_NAME: Minimum Version of OPatch
PREREQ_DESC: Check if the required version of OPatch is present on the target
PREREQ_TYPE: PATCH_TOOL_CHECK
PREREQ_STATUS: FAILED
PREREQ_MESG: Unable to get the version of OPatch at
/u01/app/oracle/product/12.1.0/dbhome_2/Opatch
We have opened an SR to see if we can get more info on what was already identified as a bug. Has anyone else experienced this issue? If so, can you share any patches or workarounds (other than manually applying patches) that you found useful?
Thanks.

You'll probably get the same info from Support, but the workaround is to use the Patch Database (however that doesn't work if there's no DB target associated to that home). If you were trying to do patchign out of place (clone home, patch, then move db's), EM can do this for you. If you're just installing a new DB Home and trying to patch, then i don' think there's another workaround. The base bug is marked fixed though, so a backport for the 12.1.0.6 plugin should be available very soon. I would ask the support analyst to request the backport for your plugin/patch level...

My school has a website. The professor uploads files in Word. When I click on the link at home using Pages, the download window opens with nothing in it and Safari opens with a blank in the address book. What Could be wrong? Wrong set up?

Hi Jo,
If I'm interpreting this correctly, the Word file downloads correctly, but when you open it in Pages, the link(s) which your instructor has embedded in the Word file are not correctly translated into Pages.
If the link shows the actual address, you should be able to copy that and paste it into the location bar in Safari, press return, and get to the website that way.
An alternate route might be to download one of the open source Office applications, OpenOffice.org, LibreOffice, or NeoOffice. These are written to more closely emulate the behaviours of MS Word than Pages, and may provide better support for links embedded in Word files.

Call procedure with MS SQL from linked Oracle server

I have a procedure on a remote server that I can call from SQL*PLUS
set serveroutput on
declare rez varchar2(99); msg varchar2(99); begin radar.test('AL25',rez,msg); dbms_output.put_line('Rez='||rez);
dbms_output.put_line('Msg='||msg);
end;
it gives me the neccessary result.
But I need to call the same procedure with MS SQL from a linked Oracle server, I'm trying to do it through openquery for a while, but no success yet.
Can someone tell me what is the right syntax for that query in OPENQUERY?

Have you tried configuring Oracle Heterogenous Services/ Transparent Gateway? This would let you link Oracle to SQL Server via a database link which should solve your problem.
