Lost init.ora file

hi
on one of our database we have lost an init.ora file. is there a way to recover this file if one does not have a backup of this file
regards
kedar

What version of Oracle you are using?.
If your database is oracle9i and running
then you can create init.ora from spfile.
Hope this will be useful.

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!!

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,
SQL> show parameter spfile
NAME TYPE

spfile string
/u01/app/oracle/product/10.2.0
/db_1/dbs/spfileorcl.ora

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

SID

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).

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!

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.

Init.ora file parameter 'processses' not working

When I change the number of processes in my init.ora file from the default of 30 to 200, I get an error when accessing from SQLPlus that Oracle cannot be found. I run Oracle 8.1.6i on a Solaris v7 platform. Any suggestions???

I think your database could not "be found"
'cause it isn't up.
Change the init.ora file parameter 'processses' to 'processes' and restart
the database.
Oracle refuses starting up, if there are
mistyped parameters in init<SID>.ora.

Init ora file for 2000 server oracle

i'm running 9.02 on windows 2000. How do i find out which init ora file the start services is picking up. I looked it up in the registry and it wasn't obvious.
thanks

Hi,
All oracle parameters registry related can be found in the book for window. If you don't see the init which is pointing to it is going to the default. Look in ORACLE_HOME\database

Setting of init.ora file for 500 users

how to set diffrents parameters in init.ora file
for 500 user
(hybrid system)(oltp+dss)
thanks

Yeah, it depends and you will need to adjust thoses parameters during the "life" of the database.
I give you some of my thoughts (that's just thoughts, not a rule => there is no perfect rule) :
500 users = Unix box i guess so :
If MTS (dont think u need MTS for 500 users) => SGA = 75% of the RAM of the server
If NOT MTS (dedicated processes) => SGA = 50% of the RAM
Say 2GB of RAM on no MTS :
buffer cache = 900 MB
shared pool = 100MB to 200 MB
sort_area_size = 256KB
something like 50 to 100 RBS (depends on how many users are connected simultaneously)
for the users which will not do some OLTP operations, you should make few BIG RBS and assign their transactions to them. for thoses users, you probably need a bigger sort_area_size.
all the tablespaces LOCALLY MANAGED
backup with RMAN

Usage of init.ora file ?

Hi everybody,
can anyone explain me in detail about the usage of init.ora
file. thank u
hav fun
prabhu.

Prabhu,
As you probably noticed, one book is not enough when preparing for the exams. Also, you need a library of books just to be a DBA. Although some people could do it strictly from memory, when you are working with live systems, it helps to have an extensive collection to reference on a day to day basis. The following is a list of my most recommended books. For a syntax reference book, I would reference "Oracle8i: The Complete Reference" by Kevin Loney and George Koch. Although this will give you the syntax you need to compose the "Create Database" script, you will still need the other books to understand what parameters you will want to set.
"Oracle8i: The Complete Reference" by Kevin Loney,George Koch
"Oracle8i DBA Handbook" by Kevin Loney,Marlene Theriault
"Oracle8i Backup and Recovery" by Rama Velpuri,Anand Adkoli,George Williams
"Oracle8i DBA: Network Administration" by Barbara Ann Pascavage
"Oracle8i PL/SQL Programming" by Scott Urman
"Oracle Performance Tuning Tips & Techniques" by Richard Niemiec, Bradley Brown, Joseph Trezzo
This is not the complete list of books that you will want as a DBA. There are many great books on Oracle. This is mainly my core recommended reads. If you are studying for your certification, don't be surprised if it takes you a long time to prepare. It is not unusual for it to take more than a year to become certified as the Oracle exams are pretty thorough and require a lot of information. I would also recommend you take the practice exams prior to taking the certification exams. I still have nightmares about taking the Performance Tuning exam. (And I'm no slouch.) I'm not trying to scare you out of taking the exams because I believe that they are very beneficial to DBAs. It will give you a more rounded education in Oracle database administration. Especially if you haven't had a lot of exposure to database administration. Before you take the exams, you will have to understand the application of the knowledge and not just the book material. And it's a lot of material. Good luck to you.
