Oracle 9i vs Oracle11gR2 init.ora parameters

Hi,
Can you please let me know what are the added init.ora parameters in oracle11gR2 than when compared to oracle9i init.ora prams?
Thanks

Hi;
Can you please let me know what are the added init.ora parameters in oracle11gR2 than when compared to oracle9i init.ora prams?Lots of thing have been changed those 2 produtc, bacily 11g parameter perform more flexsibility.I belive its hard to define what exactly changed. Please see below links:

Are there any init.ora parameters which can't be changed at all ?

DB version: 11gR2
We have the following two types of initialization parameters
Dynamic - Which can be changed without a DB bounce (example CURSOR_SHARING)
Static - Which can be changed only with a DB bounce (example MEMORY_MAX_TARGET )
Both types of init parameters mentioned above can be changed with or without a DB bounce. Are there any initialization parameters which cannot be changed at all with or without a DB bounce?

Max wrote:
Oracle documentation which describes init.ora parameters is 'Oracle Database Reference 11gRelease 2'. It doesn't answer my question
Maybe it does.
from DB_BLOCK_SIZE
The value for DB_BLOCK_SIZE in effect at the time you create the database determines the size of the blocks. The value must remain set to its initial value.

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

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.

Evolution of init.ora parameters

Hi Gurus,
Can someone name the milestones (or important) in the evolution of parameters in init.ora file. I knew for every release certain parameters are relegated, or replaced and few are introduced as new and ofcourse for some the default values are changed. I want to understand the most important changes Oracle has come up at 8i, 9i, 10g and 11g releases.

Init.ora parameters

Hi,
Which init.ora parameters are respond for write data from cache to redo logs files? It is possible to set this parameter as time or rather for cache usage?

Dear,
The purpose of redo generation is to ensure recoverability. This is the reason why, Oracle does not give the DBA a lot of control over redo generation. If the instance crashes, then all the changes within SGA will be lost. Oracle will then use the redo entries in the online redo files to bring the database to a consistent state.

What init.ora parameters needed for RMAN,

Hi,
We would like to implement RMAN at our site and like to know what are the parameters required in init.ora for using RMAN, where can I find more info regarding the tuning of these parameters ? Please reply..
Thanks a lot in advance,
Sreedhar

Tammy,
Thanks for your reply. I didn't post the exact question, let me do it again.
I need to determine the 'large pool' size to be implemented for using RMAN. (We already have RMAN running).
I need to know what parameters I need to set in init.ora for large_pool to work efficiently in conjunction with RMAN. How do I calculate the required size.
I found some material on this, here, but it's confusing.
By default LARGE POOL = 0, unless PARALLEL_AUTOMATIC_TUNING = TRUE, (in which case LP will be set automatically). Also, set LARGE_POOL_MIN_ALLOC to a non-zero value to enable a minimum allocation with LP.
When I read document (ID 73079.1) it gets more confusing, as whether to take MULTIBLOCK-READ-COUNT value or db_file_direct_io_count into consideration.
Any help is appreciated.
Thanks again, Sreedhar

Parameters in init.ora not changing in DB

Oracle 9.0.0 Redhat 7.2
Trying to set up utl_file_dir in the init.ora file and, although
the entry in the init.ora looks correct (utl_file_dir=/tmp/xxx),
the value for utl_file_dir in sqlplus (show parameters utl)
never sees the value (ie always shows nothing). Same with other
params in the init.ora. If I rename the init.ora file, the DB
doesn't start, so I'm changing the correct file.
Maybe Oracle is finding something it doesn't like in the
init.ora file and aborting reading the file??
Is there a way to see what oracle's doing with the init.ora file
as it loads?
Thx Martin ([email protected])

There is a new feature with 9i that you can change init.ora
parameters without bouncing the instance, these parameters are
store in a file (spfile).
See the documentation about this feature.

What are the recomended init.ora params?

Hi,
I am following the Doc ID: 298877.1 of MetaLink.
Let we have
50 captures processes on Central Servers which are capturing the "ABC" Schema (DDL's,DML's),
50 propagations (Each capture process has it's own Propagation queue),
50 apply (All 50 sites apply processes apply changes on central server).
DEL Machine 2950: RAM=4GB :
My capture process state is "Pause For Flow Control..".
All sites and central server used same schema:
My current setting are:(Which I selected)
--> Compatible='10.2.0.1.0'
--> SHARED_POOL_SIZE=140M
--> PARALLEL_MAX_SERVERS=200
--> JOB_QUEUE_PROCESSES=100
--> OPEN_LINKS=30
--> PROCESSES=500
--> SESSIONS=70
--> SGA_MAX_SIZE=500M
--> STREAMS_POOL_SIZE=200M
Can anyone help me to proper setting up the following init.ora parameters?
--> SHARED_POOL_SIZE
--> PARALLEL_MAX_SERVERS
--> JOB_QUEUE_PROCESSES
--> OPEN_LINKS
--> PROCESSES
--> SESSIONS
--> SGA_MAX_SIZE
--> STREAMS_POOL_SIZE
Thanks,

The recommended init parameters are clearly spelled out in the docs at http://tahiti.oracle.com and no doubt you can read them as well as we can.
My only recommendation would be to patch to 10.2.0.4 first.
PS: Some of the things you are asking about no one can possibly answer without knowing everything about how the system is used. For example
the number of open database links? Are they used by anything else? How can we know. Number of session? How can we possibly know the number
of connected sessions on your server? This is something you need to do yourself or ask your DBA to help you.

RMAN and init.ora

What are init.ora parameters that controls behavior of RMAN in Oracle 10g r2. Thanks, R

Could be the parameters that you set when you configure the backup of a database
alter system set log_archive_format='orcl_%t_%s_%r.arc' scope=spfile;
alter system set db_recovery_file_dest_size=800G scope=both;
alter system set db_recovery_file_dest='+RECOVERY_1' scope=both;
alter system set log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST';

Recommended init.ora values for PROD setup

Hi All,
-Assuming that I am using a 64-bit version of Oracle,
-that there is nothing else running on the server,
-that there will be no other databases on the server,
-that I have substantially more data on disk than I have RAM,
-and that I am using 11g. I want to setup a production database 11g. The server specs is OEL 5.6 with 12Gb Ram and a Quadcore CPU.
There will be 200 users simultaneously accessing the database. I understand that 10g and 11g are "self-tuning".
So in this regard do I need to still change values in the default init.ora?
Can you give me sample PROD template of your init.ora?
Or maybe since my RAM is 12Gb I will just set the "target SGA = 8Gb" and the database will now be good?
Thanks,
Yx

Adding Justin's assumptions

I Thank you all :)
You need to understand what the memory is used for. Please read the documentation on SGA and PGA components and parameters and how they impact performance.Yeah I read it already....but it does not clearly explain like what all you did here ;)
Hmm interesting....I got lots of tips learned. So If I have 500Gb data (im sure it does not include index right?) Broken into the following:
Table1 300Gb
Table2 100Gb
Table3 50Gb
Table4 30Gb
Table5 10Gb
Table6 5Gb
Others 5Gb ( comprised of hundreds of tables)
Do I need to have my memory target SGA equal to 500Gb to attain a maximum performance? supposing memory is not a budget constraint?
Supposing Table6 is the most frequentlly read/accessed and I want to load/cache it all in the memory so I do not need to index this table, how can I do it?
What is the rule of thumb of PGA size against the size of the table? Maybe 20% sorting of the most accessed table?
@Justin
**10 sessions doing data warehouse queries will probably need more PGA than 1000 sessions doing OLTP queries.
**I'd probably start with a MEMORY_TARGET of 10 or 11G. How about the approx. PGA size dear? :)
@Hemant
It is more the amount of data and some factoring for the number (volume) of changes to the data.
The number of users matters in terms of sizing memory for server processes, and some allocation of the SHARED_POOL_SIZE, not for the DB_CACHE_SIZE component.
If more users means more distinct SQL statements, the SHARED_POOL_SIZE usage would be greater.
However, multiple users accessing the same version of the data will be "sharing" one buffer in memory for each block of data being accessed. It doesn't matter if 1 user is reading a block or 8 or 64 or 128 users are reading the same block -- in either case it is one buffer in memory.
It is only if the block is frequently being changed and concurrently queried, might there be current and a few consistent versions of the buffer being maintained in the SGA.I think in 11g I do not need to set those because it is "self-tuning" right? All I need is the target SGA size. :)
Given that I will perform a "benchmark" test/simulation on the DEV server. Is there a tool that will gather the right sizing of init.ora parameters? Can I extract it from AWR report?
Thanks to all again,
Yxz

Moving init.ora file

Hi,
I'm in 8i on WinXP. By doing following I move init.ora file :
SQLPLUS>shutdown immediate
user>oradim -EDIT -SID DB1 -PFILE C:\oracle\admin\db1\exp\initdb1.ora -startmode auto
Now if I start the service, it is OK and DB would be open. but if I issu startup I have errors :
SQL> startup
LRM-00109: could not open parameter file 'C:\oracle\admin\db1\pfile\initdb1.ora'
LRM-00113: error when processing file 'C:\oracle\admin\db1\pfile\initdb1.ora'
ORA-01078: failure in processing system parameters
Even if registry fir pfile key is changed, it is with new position of init.ora file, but startup command line look for ancient init.ora file, Why ?
I should use :
SQL> startup pfile='C:\oracle\admin\db1\exp\initdb1.ora'
Any solution ?
Many thanks.

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
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
Uwe
