Increase the sga to 8gb

We want to increase sga 8gb, knowing that we have the physical size of the ram 24 to go.
we followed the configuration steps as the oracle note 225349.1, we modified the boot.ini file by adding the / PAE, the AWE is configured to 2147483648, when starting the instance we have the error message ORA-00371: not enough shared pool memory, Should Be atleast 434653184 bytes

I have a 15' Macbook Pro, mid 2010 running Mavericks. I want to upgrade the hardware by increasing the RAM to 8GB and replacing the HD for a SDD one. What would be the best way to install mavericks on the new HD? I have the original OS X CD.

I have a 15' Macbook Pro, mid 2010 running Mavericks. I want to upgrade the hardware by increasing the RAM to 8GB and replacing the HD for a SDD one. What would be the best way to install mavericks on the new HD? I have the original OS X CD.
From what I read, I have 2 choices: 1. to install OSX and then upgrade to Mavericks, but I'm not sure if this would be possible (to upgrade directly from OSX to Mavericks); and 2. to use a software called Super Duper.
I wouldn't like to have to use a third party software to do this, so the question is: is there a better way to install directly the Mavericks not having to use a third party software?

Install the new drive in the computer.
Install the old drive in an external USB or Firewire enclosure.
Boot the computer from the Recovery HD on the external drive.
Use Disk Utility to partition and format the new internal drive.
Clone your external drive to the internal drive.
How to replace or upgrade a drive in a laptop
Step One: Repair the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Step Two: Remove the old drive and install the new drive. Place the old drive in an external USB enclosure. You can buy one at OWC who is also a good vendor for drives.
Step Three: Boot from the Recovery HD on the external drive. Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the Recovery HD then click on the downward pointing arrow button.
Step Four: New Hard Drive Preparation
1. Open Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your new hard drive (this is the entry with the
      mfgr.'s ID and size) from the left side list. Note the SMART status of
      the drive in DU's status area. If it does not say "Verified" then the drive
      is failing or has failed and will need replacing. Otherwise, click on the
      Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from
      the drop down menu to one. Set the format type to Mac OS Extended
      (Journaled.) Click on the Options button, set the partition scheme to
      GUID then click on the OK button. Click on the Partition button and
      wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the
      drive entry) from the left side list. Click on the Erase tab in the DU main
      window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the
      Options button, check the button for Zero Data and click on OK to
      return to the Erase window.
6. Click on the Erase button. The format process can take up to several
      hours depending upon the drive size.
Step Five: Clone the old drive to the new drive
1. Using Disk Utility still opened.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the
      Destination entry field.
6. Select the source volume from the left side list and drag it to the
      Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new internal drive. Source means the old external drive.
Step Six: Open the Startup Disk preferences and select the new internal volume. Click on the Restart button. You should boot from the new drive. Eject the external drive and disconnect it from the computer.

***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

Error when i increase the SGA to more that 1GB

I have a server with 8 GB of memory running server 2003. i have 2 instances on the server, everytime i try to increase the SGA for any instance to more than 1GB the instances doesn't restart. the error message is 'Memory realm already exists' among others.

the error message
is 'Memory realm already exists' among others.This error is pretty self-explanatory,
Error:     ORA-27100
Text:     shared memory realm already exists

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
Now the SGA Size is below
Total System Global Area 3747585360 bytes
Fixed Size 736592 bytes
Variable Size 1593835520 bytes
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.
Regards,
Suresh Kumar

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.

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.

So i believe, I need to increase the SGA and PGA size...No, IMO, your believe doesn't hold much base as the evidence that you have used is insufficient. What is the debugging mode or compile mode ? 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.

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 .

Increase the SGA size!

Hi,
We are using EBS 12.0.6 and DB 10.2.0.3.
Currentlly My SGA is 2 GB and we have 8 GB of RAM, and Swap area is 10 GB.
Please recommemded us to SGA size and related DOC ID.
thx.

Hi again;
In addition to my previous post also check

Increasing the SGA Size to Reduce CPU Run Queues?

I got the following e-mail message from one of our UNIX admins and wanted to know if anyone can shed some light on this:
I was just talking to [a consultant] about the problems on [the database server] and he pointed out that he has seen extremely high CPU run queues on this server, despite the fact that average CPU usage is not hitting 100%. We did some more digging and memory is being poorly utilized on this server. There is a lot of available memory that is not being used. We think that the run queues are running up because we have multiple reports coming in and sitting on the individual CPUs but they aren't able to fully utilize the available CPU. We were wondering if it would be possible to adjust the database to use more of the available memory and see if that allows the queries to use the CPU more effectively.

So, there are a lot of things that could be happening, and your post doesn't even begin to point in the right direction. Is your system heavily batched? You might speed report things up by slowing down the batch and letting other things use the cpu's. What does Oracle think it is waiting on?
As the comments cited above suggest, Cary's book addresses how to figure these things out. Big CPU run queues are certainly an indication of tuning necessity, perhaps on both the Oracle and OS side. It could even be something silly like I/O being too slow so the CPU's are waiting on that stuff. There are enough variables involved it can very quickly become like squeezing balloon animals if you don't use a structured approach.
So, what all hardware is involved? What are your init.ora parameters? What exact versions of everything? What do OS utilities show?

to increase the sga size over 5GB its not accepting it.What happens? Any errors, does the instance crash?

I have the MacBook Pro (retina, 13 inch, Mid 2014) Memoria 8GB 1600 MHz DDR3 and I want to increase the memory. What kind of memory do I have to buy?

The RAM in the retina model can not be upgraded.

Will increasing the memory from 4Gb to 8Gb make a big difference to the speed of my Intel Core Duo 2 Mac mini?

Well, technically no, CPU will remain the same speed. But having 8 gig will give you some room for memory hungry apps and run better with multiple apps.
Adding a SSD drive will give a second life to your macmini. I did mine a few weeks ago (240 gb SSD ) and also went from 2 to 4 gig ram. It's like having a new computer!
Good luck!

Increasing the size of the SGA

I'm using the Oracle Enterprise Manager Database Control on a 10.2.0.4 instance running on Redhat Enterprise Linux. One of the recommendations that the AWR\ADDM always seems to give is: "Increase the size of the SGA by setting the parameter SGA_TARGET to N". I've gone through the process twice already by upping the SGA_MAX_SIZE and SGA_TARGET parameters. It's currently recommending to up it to 6176M, I have not done this yet.
(1) Is this one of the recommendations that you would ignore within the DBCA if performance of the database seemed acceptable?
(2) Why does it always come back from the AWR\ADDM as a recommendation?
(3) What SQL or performance statistics does it do to determine whether the SGA is undersized and how does Oracle determine the SGA recommended size that shows up in the ADDM feedback?
Thanks in advance...

Truely new questions do deserve new threads. Questions that are a direct result of responses to the initial question should be asked on the same thread.
If there has been a time gap between the last post on the initial thread and the new question coming to mind then a new thread is probably the better choice.
To answer the question asked if the database is not suffering ORA-04031 errors and performance is OK then I would ignore the recommendation to increase the size of the SGA yet again.
What you might want to do first is reivew how the sga is being used (v$sgastat) and look for bad code technique that leads to needing memory, i.e., the use of SQL that passes constants to Oracle in what would otherwise be the same SQL statement if a bind variable was used and excessive use of Dynamic SQL when again bind variables could have been used in the SQL.

Hi is there anyway I can increase the memory on me 8gb Ipod touch

There are, however at least a couple of alternative that might be worth looking at:

There might be other solutions I'm not aware of, but one of those two might work for you.
