Increase the SGA and PGA size

Hello Guru,
How do i check what is my SGA and PGA..I am using TOAD..
I need to increase the SGA and PGA size...Please help..
I have a table having 200 million records, all indexes are there for the column..But it hang on in the debugging mode and also compile mode..
So i believe, I need to increase the SGA and PGA size...
Thanks,

The current size for both SGA and PGA can be shown depending on the version of the db. For 10g, the SGA size is shown by sga_target parameter and PGA size is shown by pga_aggregate_target parameter. For 11g, the parameter memory_target sets them both.

For what purpose you are using these modes? 200 million is not a very large number if you ask me. Tell us your db version and based on it, generate a Statspack or AWR report and post here.

Suggestion in increasing the SGA and PGA after increase in the RAm of the machine .

Hi All,
Need an expert suggestion on the change's in the SGA and PGA of the oracle database after increasing the size of the machines RAM .
We have 64G of RAM in the machine .
There are 9 DB's running on oracle 10g and 11g on this machine
The total SGA of all the database's is around 18G .
DB1 has 2G of MAX_SGA_SIZE
DB2 has 8G of MAX_SGA_SIZE
DB3 has 1G   of MAX_SGA_SIZE
DB4 has 2G    of MAX_SGA_SIZE
DB5 has 676M   of MAX_SGA_SIZE
DB6   has 1.5G   of MAX_SGA_SIZE
DB7 has 1.2 G   of MAX_SGA_SIZE
DB8 has 675M   of MAX_SGA_SIZE
DB9 has 672 M   of MAX_SGA_SIZE
Now the machine RAM is up to 96G 64+ 32
what would be the suggestion on the increase in the SGA and PGA max size .
Any expert suggestion is highly apprciated .
Thanks in Advance

Thanks for this Justin.
Here the exercise is to add 4 CPU's and 32G RAM to the server earlier it was with 4 CPU's and 64G RAM this was decided by the server support team .
here is the stats from SAR   command ..

Now that the 4 CPU's and RAM is been added , my request is how to calculate the required kernal parameters for oracle to this new configuration for some improvement in the oracle performance .
like kernal.shmmax
      kernal.shmall
/dev/shm file system
largest value of MEMORY_MAX_TARGET or MEMORY_TARGET of all instances
the oracle is set as automatic memory management . it is not an RAC environment .
Any Expert suggestion is highly apprciated .
Thanks in advance .

log_buffer     10485760
Please Suggest Me the How Much Value also to increase the SGA
My RAM SIZE is 6 GB
Regards
***SBJ***

SGA size on 8i is static , and for increasing the size you have to make the changes in the pfile and bounce the database
First thumb rule is that your SGA should not exceed more than 40% of your PHYSICAL RAM in oracle <= 8i version. You can go around 80% from oracle 9i onwards

How to know the amount of ora 11g page-out memory (sga and pga)?

How to know the amount of oracle 11g page-out memory ( sga and pga) in the SunSolaris 10 Unix and Linux.
I need to know how many oracle memory are being page-out ( all and for a one oracle server process).
thanks

You can monitor the paging with vmstat or sar commands.
http://download.oracle.com/docs/cd/B28359_01/server.111/b32009/tuning.htm#sthref500
You can also get the paging information on OEM home page if configured for your database.
But I don't know if there exists a method with which one can find out how much memory per session/server process is getting paged out.

Increase the SGA Memory

Hi,
Iam using oracle 9i OS Solaris version 9.2.0.6
I am new to Oracle Database and i learn DBA any help me.
My Database Ram Size is 16 Gb

Database Buffers 2147483648 bytes
Redo Buffers 5529600 bytes
Now i want to increase the SGA size to 5 Gb
How to increase the SGA Size and give the examples SGA Based parameters also i want to increase so Kindly Help.

Hi.It is correct that you must look into the documentation as the first-point-of-resource.It will be more quicker than to wait for the reply here.Not to say that don't post your question but do a search, get some thing in your hand,read it and when you dont understand it than post the question here.It will be more better approach of learning.
For your question , in 9i you can't increase the total memory for your SGA on the fly as like you can (to some extent).If you want to increase the total memory allocated to your SGA than you need to change the parameters which constitute the total memory for the SGA in 9i.REad here.
http://download.oracle.com/docs/cd/B10501_01/server.920/a96521/create.htm#998095
SGA_MAX_SIZE parameter controls the total memory allocated to your SGA in 9i.You need to change its value in the parameter file/spfile and bounce your db to reflect teh changes.

Guidelines for SGA and PGA tuning for 10gR2 RAC and ASM ?

I am looking for tuning information on SGA and PGA tuning for Oracle 10g (10.2) RAC and ASM for a 4TB OLTP and DSS mixed environment on Solaris 10 platform.

We are running Solaris 10 SPARC 64 bit with Oracle 10gR2 RAC Enterprise Edition and ASM on Sun servers with 32GB of RAM for memory for a 4TB OLTP database.
It is in design phase so I do not have an existing AWR or Statspack report yet. Is there a best practices guideline on how to size parameters for the SGA (ie: shared_pool_size, etc) and PGA for this environment from Oracle?

Manually allocate SGA and PGA to a Instance?

1) Can we Manually allocate SGA and PGA to a Instance after . startup
sql>show user
connected to idle instance
2) In which type of memory user is stored in oracle mem or windows memory.
Thanx

If you are using 10g, you can modify PGA size after instance startup by alter system to change PGA_AGGREGATE_TARGET
You can't increase SGA_MAX_SIZE while instance is running. However you can change effective SGA size by alter SGA_TARGET if you are using ASMM
to find out what's current logon user,
select user from dual;
Don't quite understand your second question.

How do I change the font and graphic size when using Firefox

I have recently switched from Windows to Mac. When resizing the window in Mac the font and graphic size do not follow -- they stay the same size and only more "white space" is created by increasing the window size. How do I get the graphics and fonts to adapt to the new window size or at least make the whole image bigger. I am using Firefox 3.6.12 and Mac OS10.6.5. Thanks for the help.

You can select to zoom the full page or only the text: View > Zoom > Zoom Text Only<br />
Firefox 3 can remember the zoom level site specific.

hi
connect as sys user and then try...
first make folder as backup and then copy the old SPFILEorcl to the same folder(backup)
now you can easily modify the files otherwise you will get error..
you will find here..

and do the following...
1).SQL>create pfile from spfile;
2).modify the pfile and decrease\increase the size of pools.
3).shutdown database.
4). Startup database using created pfile.
if it start ok then.

How to change SGA and PGA in 10g r2 RAC

Hi,
How to change SGA and PGA in 10g r2 RAC, its Linux.

Hi,
Here is the way i followed to change SGA and PGA in RAC.
Action Plan to change the memory parameter in the production environment(5/21/2010)
Note:
=====
Practice should be done in the DEV/TST environment before moving to Production;
Although the procedure could be applied in the testing environment the changing values
used in the testing environment should be modified since RAM number are not the
same between the testing servers and production servers.
1.     Make changes to these two parameters in one of
     the prod instance, e.g. PROD1
     ====================================================
     login as sysdba on sqlplus
Change :
alter system set sga_target=28G scope=spfile sid='*';
Change :
alter system set pga_aggregate_target=4G scope =spfile sid='*';
     sql>alter system set pga_aggregate_target=4G scope=both;
     sql>show parameter pga_aggregate_target;
          -- should see the altered number on both instances
Change:
sql>alter system set sga_max_size=28G scope=spfile sid='*';
sql>alter system set sga_max_size=28G scope=spfile ;
sql>alter system set sga_target=28G scope=spfile;
3.     shutdown database PROD (two instances should be shut down)
     $>srvctl stop database -d PROD
     $>. /$ORA_CRS_HOME/bin/crs_stat -- to check for the database status
4.     bring up database PROD (two instance should be brought up)
     $>srvctl START database -d PROD
     $>. /$ORA_CRS_HOME/bin/crs_stat -- to check for the database status
     login into both instances as sysdba to check
     sql>show parameter pga_aggregate_target
     sql>show parameter sga_max_size
          -- should see the altered number still there in both instances
          -- from step 1
     -- After confirming above two parameters are altered on both instances,
     -- then issue the syntax below in one instance
5)     check everything is ok
