Init.ora file location

Hi,
Is there any query by which i can find out the location of init.ora file. We are using unix server.
Thanks in advance.

The location of the init.ora file was not stored in the database because with Oracle8 it was possible to start the db remotely using a local init.ora file ( I never did it myself but I did read about it, proberbly on asktom). So a '/tmp/init.ora' would have been meaningless because you would not know which machine it refered to.
If you have lost your init.ora file it is possible to recreate it by quering v$parameter, if your on 9i or above you can do
'create pfile from spfile' to get a new copy if you are using an spfile that is! A 'find' on the unix might be the quickest!!

Questions on init.ora file

Hi,
I have some questions on init.ora file. While checking the init file in my system i found that it defines a spfile in a non default location.
The parameter names are like
1) db1.__db_cache_size
2) *._kgl_large_heap_warning_threshold
3) *.sga_target
what do they indicate? I mean what does 'db1.__' , '*._' and '*.' indicate? There are multiple database in the Windows 2003 server and the db version is 10g R1

From the discussion i guess the following points
1) db1._ means they are specific to databases.
2) *._ and * means they are used accross databases and chaging it in any of the initfile might affect all? I seriously doubt this.You are mistaken when speaking about database. Bear in mind, a database is not an instance.
* here means this parameter will apply to any instance of that database (if it is in RAC), or to the only one instance of that database (if it is in non-RAC).

Regards,
Bala.Taken note of yingkuan's comments about directory objects - which don't need a utl_file_dir entry - if you really still need to know (on e-business suite or some other product that needs them) then UTL_FILE_DIR is an initialisation parameter which takes a comma separated list of directories on the database server and to which the oracle software owner (usually oracle on *nix systems and system on windows) has read/write access. To set it therefore you'll need to identify or create your directory and then either
a) add the line UTL_FILE_DIR=/path/to/dir1, /path/to/dir2
to your init.ora if you are using one or use
b) ALTER SYSTEM SET UTL_FILE_DIR=/path/to/dir1, /path/to/dir2 SCOPE=SPFILE;
if you are using a server parameter file.
You should be able to find this and more information in the documentation for your version of Oracle.

Which init.ora file in use?

I found init.ora in a couple places.
How do I determine which init.ora file my oracle is using?
Is there a sqlplus command to fine the init.ora in use?
So far, I found them here:
c:\oracle11g\dbs\init.ora
c:\oracle11g\admin\mydb1\pfile\init.ora.8172009222712
Which one is active?
Any suggestions are greatly appreciated.

The one that's there in the DBS folder is the first one that is going to be looked upon by Oracle when it will try to start the instance. The one in the $OH/dbs/ is going to be active. The other location would not have the pfile all the time. Also, spfile should be used if you are in 11g. Why you areusing pfile instead of it?
Here is what I have for 11g system,
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - Production
With the Partitioning, Oracle Label Security, OLAP, Data Mining
and Real Application Testing options
SQL> show parameter spfile

Init.ora file in SAP

can anyone tell me where is the location of init.ora file in SAP R/3

Its under /oracle/<sid>/102_64/dbs

After an import, replace the init.ora file?

I have just successfully imported a database from Oracle8i to Oracle10g. Now, is it safe to replace the init.ora file?

Replace the 10g init file with the 8i? Nope. You should be reading the release notes and upgrade guide, and taking into account the obsolecense of some parameters, the introduction of new ones, etc.
Also, your control files are probably in a different location, you have different RBS's etc..

Missing "init.ora" file

I search lots of website to find out how to create batabase by manual without using OBCA. Almost of the website said that I need to find the "init.ora" file,
then copy and edit some of the parameters. But the problem is I couldn't find
"init.ora" file in Windows XP Pro. Is thers someone can tell me the exactly path for this file or help me to create a New "init.ora" file ?
One more question. Does this file exist before I create new SID or after ?
Thank you.

Hi,
go to start menu and click search option then find init.ora or *.ora, see results ? anyways the location of the init.ora file is d:\oracle\0ra90\admin\sample\pfile if you replace ora_home with d:\oracle and your db must be oracle 9.0.1.you can do one more thing use dbca to create a sampme file.use it and at the very last step uncheck create database and check create script sort of option.save it and use it accroding to your requirement.
thanks
Alok.

How to find current init.ora file

I have 2 issues:
Issue 1:--
I have some 4-5 init.ora file which are created by some other user and facing difficulties to find exact init.ora which is used by my oracle 9.2 database. same thing for spfile.
Is there any way so that i can find the currently use init.ora file?
Issue 2:
I want to change init.ora file parameters for the oracle9.2(siebel).
Presently default it is showing optimizer_mode=CHOOSE
I have tried to change to RULE but not refelecting after database restart.
at session level i can modify but i want permanent change and for thius i tried with
user SYS as SYSDBA with
ALTER SYSTEM SET optimizer_mode=RULE;
but getting following Oracle erroe message
ORA-02096 specified initialization parameter is not modifiable with this option
Cause: Though the initialization parameter is modifiable, it cannot be modified using the specified command.
Action: Check the Oracle9i Database Administrator's Guide for information about under what scope the parameter may be modified
How we can make changes in init.ora file?
Regards
Junu

As far as I know, there's no possible way to find out which parameter file was used to start instance. And, even if it was, I don't really see much sense in it because parameter file is a client-side file, and usually it required to start up Oracle instance remotely.
In principle, parameter files are obsolete beasts, consider using server parameter file (SPFILE) instead. And, for SPFILE, it's pretty easy to find out its location:
SQL> show parameter pfile
NAME                                 TYPE        VALUE
spfile                               string      %ORACLE_HOME%\DATABASE\SPFILE%
                                                 ORACLE_SID%.ORAAs for your ORA-02096 error, you have two opportunities to resolve it.
If you decided to use SPFILE, create one (for example, using CREATE SPFILE FROM PFILE command), start your instance with SPFILE then issue:
ALTER SYSTEM SET optimizer_mode=RULE SCOPE = SPFILE;and bounce your instance.
If you still wish to use old-style parameter file, you have to add corresponding setting into that file manually (it's a plain text file in fact) and restart instance.
Regards.
P.S.: Why do you want to enforce rule-based optimizer by the way?...

Can we determine path of my INIT.ORA file from data dictionary views.

Hello Guru’s
I am new to oracle, My question is for the sake of my knowledge: I work on oracle 10G.
Is there any data dictionary view from where I can get the path of my INIT.ORA file.

AFAIK , its no. You can check the path from the show parameter command like following,

How to establish a single init.ora file for 3 node RAC under ASM

All,
Our environment is a combination of several different memory sized SUN machines (V880, V490 & 250R).
Setting up a single init.ora file that encompasses each of the nodes memory into the SGA sizing is our desired setup.
Though we have established the file, the question is getting each NODE on the RAC to use that single parameter
file to start its database instead of taking the default init.ora file in the default (asm/dbs) directory.
As we have performed fail-over testing, upon the restart of instances they have restarted with wrong memory
definitions that have hung the nodes when it took more memory then what was available and swap space began
to grow.
Steps to configure and enable this process is what I am looking for.
Thanks
Gerry

Gerry,
Here's what we do. Not sure if it is relevant to your situation ...
(on each node)
$ cat $ORACLE_HOME/dbs/initrac11d1.ora
SPFILE='+DATA/rac11d/spfilerac11d.ora'
(in ASM)
$ asmcmd
ASMCMD> ls -la +data/rac11d
Type Redund Striped Time Sys Name
Y CONTROLFILE/
Y DATAFILE/
Y ONLINELOG/
Y PARAMETERFILE/
Y TEMPFILE/
N spfilerac11d.ora => +DATA/RAC11D/PARAMETERFILE/spfile.267.685170285
The spfile has all parameters, qualified by node where applicable. For example :
$ sqlplus / as sysdba

Oracle 11g init.ora file

1) I am a bit confused with init.ora file format in oracle 11g. In addition=
to the usual entries that are prefixed with *.<parameter>, it also has ent=
ries prefixed with <sid>.__<parameter>. I am not able to find an explanatio=
n of these <sid>__ entries from oracle 11g documentation. I am told by a co=
lleague that they are for instance, to cater for multiple-instances databa=
ses. Is that correct?
2) The presence of the <sid>.__ entries confuse me since some parameters ap=
pear in both <sid>__ and *. sections. What if the values for the same param=
eter are different, which one is used by oracle? I guess it's the <sid>.__ =
one?=20
3) In my case the database has only 1 instance, so I guess I can remove all=
<sid>.__ entries and only work with *. entries?
Thanks
Long

Hi,
the entries with double underscore in the spfile that you mention are not new in 11g but also show up in 10g.
They are caused by the background process MMAN (Memory Manager), that is active if you set SGA_TARGET>0 (in 10g) rsp. MEMORY_TARGET>0 (in 11g).
This MMAN modifies the Oracle Memory components like the shared pool and the buffer cache, using performance statistics captured by the MMON (Manageability Monitor) and storing the new size of the component in the spfile in order to make that size persistent through instance restarts.
The prefix of the SID is meaningless in case of a non-RAC database.
Kind regards

Archivelog Mode / init.ora file

Hi,
Maybe someone can help me out. I am presently trying to set up a dev server that has 3 or 4 databases on it. The first database is installed by the Oracle installation kit. The 2nd one that I am now trying to configure is giving me the following error: Ora-01126: database must be mounted EXCLUSIVE and not open for this operation. I am also setting it up for archiving.
When I do a SELECT * from V$database; the answer comes back that it is in noarchivelog mode. I even edited the init.ora file in both the pfile folder and the ora81/database folder and yet the answer is still the same. I even rebooted it with the same results. I understand that the database is in exclusive mode by default. Does this have anything to do with Parrelizm (spelling). I tried altering the database to archivelog mode but with no results.
Any ideas? Im at a loss.
Thanks for your time.
Al

Hi Al,
try to startup the db with startup mount or startup read only and try
the alter command again.
Normally it should work then!
