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

Setting of init.ora file for 500 users
how to set diffrents parameters in init.ora file
for 500 user
(hybrid system)(oltp+dss)
thanksYeah, 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

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.
thanksHi,
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

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

Hi,
I changed the init.ora file for some reason and I have applied some patches in OS(microsoft windows 2003 server) and i noticed in the init.ora file that all changes in the init.ora file gone !!
Can someone explain me, what was the reason behind that ?
Thanks in advance.Hi,
<humor>You have to check urgently for the green little pfile changer halfling!</humor>
Seriously.. did you do both at the same time? If so... are you sure you save the init file? Cause there's no way such changes are rolled back except if you did not saved the file... or restored an old version of your pfile!

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
JunuAs 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?... -

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???
Hi
I have a database "Xdb" running on winNT.
My "ora_home\database" folder contains the following files:
oradba.exe
OraDim.exe
PWDXdb.ora
SNCFAXDB.ORA
SPFILEXDB.ORA
and, ora_home\admin\xdb\pfile\init.ora_242323.
Well, as far as my knowledge is concerned, to start a database, we need a "init.ora" file. But I don't see any init.ora file in the above said folders, and how come the databas is getting started automatically and from where it reads the "init.ora" file when it is not present?
Explain me pls.
TIA
Aqueel.Hi,
If u want to create a init.ora file u can do the following:
create pfile='path' from
spfile;
This will generate a pfile(init.ora) which can be read.
If you want to make any changes, u can do that and you can replace the spfile in the same way. Just change the order in the above statement. Generally, the parameters can be changed with the alter system command. This explaination is just to kill your curiosity!! -

Thanx.Show the output and verify for any initialization paramtere file in $ORACLE_HOME/dbs directoryIf it really is missing (so far we only have your word, and I trust Oracle more ... show us the actual error message) and you have no backup, you can recreate it by referencing your alert log. At every startup, the alert log will record all non-default initialization parms. -
Creating two controlfiles in an auxiliary init.ora file
How can two controlfiles be created in an auxiliary init.ora file ?
for asm you can connect as asmcmd (change ORACLE_SID/HOME first) and copy controlfile (don'r forget, shutdown, modified init.ora, and startup with init.ora):
ASMCMD> cp <controlfile at disk> <controlfile at asm>
i.e.:
ASMCMD> cp '/tmp/control01.ctl' '+DATA/controlfile/control01.ctl';

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

Init.ora file at standby side
Oracle version: 11.2
Platform : Solaris 11
Both Primary and Physical standby DBs are Standalone DBs.
DB_NAME of Primary = PRIMDB
DB_UNIQUE_NAME of Primary = PRIMDB
DB_NAME of Stanby = PRIMDB
DB_UNIQUE_NAME of Stanby = STDBY_DB
I am going to create a physical standby DB for my primary DB.
After taking the backup of primary and FTPing to standby server I am going to run RMAN DUPLICATE . Before that I need to STARTUP NOMOUNT the auxiliary instance
export ORACLE_SID=STDBY_DB
sqlplus '/as sysdba'
startup nomount pfile=initXXXX.ora
rman target sys/mypasswd@PRIMDBTNS auxiliary /
run
allocate channel d1 device type disk;
duplicate target database for standby dorecover;
release channel d1;
I want to know how the init.ora file of standby DB should be named.
Should it be
initPRIMDB.ora
or
initSTDBY_DB.oraThe init.ora would be named as per the db_name parameter which in your case will be initPRIMDB.ora.
A couple of thoughts:
1) With 11gR2 you can do an active duplicate which does the duplicate on the fly so you don't need to copy files over.
2) With your naming convention if your standby becomes your primary then the naming convention of STDBY would not make sense.
Edit - Having seen msebergs's response. When you start your standby it will by default look for the pfile in $ORACLE_HOME/dbs with the namiing convention init${ORACLE_SID}.ora. However, mseberg is correct as in his link you explicitly supply the init.ora name in which case it can be anything....ie startup nomount pfile='/xyz';
