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 :

Hi,
I came across this error and I am about to start a fresh installation of the grid. (ealier one failed because it was unable to read the memory in rac2 )
Is there anything specific I can change before I start my installation.
PS - I didnt get what exactly is going on with the hosts file.

Bestpractice init.ora parameters for data warehouse in 10gR2

Hi,
We moved our 1Tera data warehouse database to linux 64 bit , 8 cpu , 8GB memory, with ASM (non RAC).
Could you please recommand best practice setting init.ora parameters in 10g
DW to achive the best performace ?
I set the following parameters:
parallel_adaptive_multi_user=TRUE
parallel_execution_message_size=2152
parallel_min_server=0
parallel_max_server=135
parallel_threads_per_cpu=2
db_file_multi_block_read_count=64
pga=900m
query_rewrite_enabled=true
star_transformation_enabled=true
db_block_size=32k
sga_target=3g
statistic_leve=typical
undo_management=auto
workarea_aize_policy=auto
db_cache_advice=on
disk_async_io=true
2. What setting would you recommand regrading the following parameters in DW (and ASM):
-- filesystemio_option :none | setall | directIO | asynch
Thank You.

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';

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,

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
Regards,
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).

# Example INIT.ORA file
# This file is provided by Oracle Corporation to help you customize
# your RDBMS installation for your site. Important system parameters
# are discussed, and example settings given.
# Some parameter settings are generic to any size installation.
# For parameters that require different values in different size
# installations, three scenarios have been provided: SMALL, MEDIUM
# and LARGE. Any parameter that needs to be tuned according to
# installation size will have three settings, each one commented
# according to installation size.
# Use the following table to approximate the SGA size needed for the
# three scenarious provided in this file:
# -------Installation/Database Size------
# SMALL MEDIUM LARGE
# Block 2K 4500K 6800K 17000K
# Size 4K 5500K 8800K 21000K
# To set up a database that multiple instances will be using, place
# all instance-specific parameters in one file, and then have all
# of these files point to a master file using the IFILE command.
# This way, when you change a public
# parameter, it will automatically change on all instances. This is
# necessary, since all instances must run with the same value for many
# parameters. For example, if you choose to use private rollback segments,
# these must be specified in different files, but since all gc_*
# parameters must be the same on all instances, they should be in one file.
# INSTRUCTIONS: Edit this file and the other INIT files it calls for
# your site, either by using the values provided here or by providing
# your own. Then place an IFILE= line into each instance-specific
# INIT file that points at this file.
# NOTE: Parameter values suggested in this file are based on conservative
# estimates for computer memory availability. You should adjust values upward

There are strange things in the file you posted, are you sure that's your init.ora ? where did you find it ?
Moreover, you use "cat" to list the file, but you name "c:\dir" the directory : what is your OS ?
Furthermore, if you use directories, then you don't need to set utl_file_dir in init.ora, and directories don't show up within parameters, you can see them by

Question on db_unique_name in init.ora for Data Guard

I need to set up only one physical standby on a different box (at a different location) for the primary db in production.
OS: Sun Sparc Solaris 10
Oracle: 10.2.0.3
Can I use the same db_unique_name in init.ora for both primary and standby DBs?
What are the minimal parameters required by Data Guard I have to specify in the init.ora in my case?
Could anyone please post an example of init.ora for both primary and standby DBs?
Thanks very much in advance.

What does your own research of 'ORA-00205' indicate?
the text of the error message is pretty self explanatory .. it couldn't find the control file.
The control files are specified by the "control_files" initialilzation paramter. When you get this error, the instance has started but was unable to mount the control file. since the init file (spfile) was processed and the instance started you can easily see what it thinks are the control files.

Your suggestions would be helpful for my configutations
Thanks in advance.

You cant generalize performance configuration. If it can be oracle would have don it. Fine tuning of parameter values is a on going process. Its not like you set it one and its done. You need to monitor it constantly and tune it on need basis.
Said that, the first thing that caught me is the setting of SGA_TARGET and PGA_AGGREGATE_TARGET. Both are set to 0 meaning Automated memory management is turned off.
Run the following two query
select name
     , value
from v$parameter
where upper(name) = 'PGA_AGGREGATE_TARGET'
    or upper(name) = 'WORKAREA_SIZE_POLICY'
    or upper(name) like '%\_AREA\_SIZE' escape '\';
select name
     , value
from v$parameter
where upper(name) in (
                          'SGA_TARGET'
                        , 'DB_CACHE_SIZE'
                        , 'SHARED_POOL_SIZE'
                        , 'LARGE_POOL_SIZE'
                        , 'JAVA_POOL_SIZE'
                        , 'STREAMS_POOL_SIZE'
This will indicate the memory related parameters that are manually set in your environment.

CHANGING THE DIRECTORY OF INIT.ORA FILE

Hi,
I have a database in 8i. Can I change the diredtory of init.ora file ? If yes how ?
it is in d:\oracle\ora8
and I want tu put it in d:\anothrfolder
Many thanks before.

Init.ora in Oracle 10g

Hi,
I installed the Oracle 10g in windows XP and I need to edit some parameters in the init.ora file.
When I searched for the init.ora file it is not available.
Please let me know whether in oracle 10g it is renamed as other file name or whether I need to edit the init.ora only in the enterprise manager which we connect through url as http://mydb:5055/em
Thanks and Regards,
A.Mohammed Rafi

Rafi,
I am sure that the database is using spfile not the init.ora file.
The location of spfile is ORACLE_HOME/database directory.
However, you can easily modify the most of the parameters dynamically using the following command from sqlprompt.
alter system parameter = value scope = both;
when you say scope = both, parameters values are in the spfile and the values also reflect the new connections to the database.
If you wanna change in the spfile, then, you need to create pfile from spfile, since spfile can't directly modified, and change/add the parameters in the pfile(init.ora) and finally create spfile from pfile.

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

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
Uwe
