How much memory are actually being used? db_32k_cache_size

Hi everyone,
Using Oracle 10g on RHEL 5.3.
I've been asked to check how much memory are actually being used by our db cache's. Currently we are using the parameters db_32k_cache_size (user-defined) and db_8k_cache_size (default) both allocated with 12gb. Now I want to know if there is any way to find out how much of the 12gb are actually being used by the cache.
Is this possible?
Thanks

Thanks Guys,
Okay, so it is using the whole 12gb. I guess the next question would be, is 12gb really needed? You see, we are trying to increase memory where possible as this database has performance issues. Now we are thinking of taking some of the 12gb that is allocated to the 32k cache and assign it to the sga for instance.
Does this make any sense?
Regards

PROBLEMS WITH HOW MUCH SPACE IS ACTUALLY BEING USED

Hello,
I've just recently purchased a Toshiba Dual Core laptop (225 gigs + 3 gig memory.) It works pretty well, but I've had to reload the windows and programs again. The reason is that after reloading I have about 203 gigs of space, but then I install flash CS3 (550 mgs and photoshop 200+) After I've installed all the doc files and everything I end up with about 200 gigs of space which is great. However, I've unistalled norton and installed AVG Professional. My space amount has gone down from 200 to about 193 gigs. I don't get it; it doesn't make sense because this is isn't how much space I've actually used. I've deleted temp files and all the install files of these other programs and what's even more crazy is that when I go ahead and run scan disk to deleted unecessary files, my space goes down in size and it shows that I have even less space! Has anyone else run into this problem? Let me know, perhaps there's a solution.
Thanks,
Tseyigai

Maybe that part number is PSLE8U-02P01D? If so, you have this model: Satellite L355D-S7901
How much space would be reasonable for me to cut back on?
I've set the shadow storage on the computers around here to 10 GB. Suit yourself.
You can save quite a bit of hard drive space by turning hibernation off. Check the size of that file. It's c:\hiberfil.sys.
And look through the stuff Disk Cleanup cites for more savings.
But if you really can't get along without more space, you should add external drives or upgrade this one.

How much memory sql server is using

Hi Experts,
I want to know how much of RAM is currently used by sql server.
is there a query for the same?
we are using sql server 2008 R2 SP2 on windows server 2008 R2 with a RAM of 48 GB. min memory as 40, max memory as 43GB.
thanks in advance.
Cheers, Vinod Mallolu

Hi Shanky
Thanks for the info. Perhaps you can clarify something for me on it.
If I run this on one of my production servers:
SELECT object_name, cntr_value MemoryUsageKB, cntr_value/1024 MemoryUsageMB,cntr_value/1024/1024 MemoryUsageGB
FROM sys.dm_os_performance_counters
WHERE counter_name = 'Total Server Memory (KB)';
select physical_memory_in_use_kb,
(physical_memory_in_use_kb/1024) as Phy_mem_MB,
(virtual_address_space_committed_kb/1024) as Total_mem_MB--memory pagefile+physical memory
from sys.dm_os_process_memory
I get this:
object_name
MemoryUsageKB
MemoryUsageMB
MemoryUsageGB
SQLServer:Memory Manager
118488256
115711
112
physical_memory_in_use_kb
Phy_mem_MB
Total_mem_MB
118363564
115589
231792
As I have LPIM enabled I'm surprised at the Total_mem_MB result, page file usage is at 0.09%. Any idea why it would be reported like that?
I'm also surprised that the DMV is reporting a lower number for physical memory usage than the perfmon counter, but I guess they're not measuring the exact same thing.
Edit: Version is SQL 2012 SP2 CU2....should have included that :)

Check what oracle installed components are actually being used in database

I have been allotted a new database which I have to optimize. So I am thinking about removing some installed components which I think are not being used in any way in database (i.e procedures calls etc). I can see a whole lot of components like "SDO","ORDIM" which I think are not being used but previous DBAs have installed them. So, is there any way to ensure that no part of database are actually using these components so that I can remove these components. Also ,what are your expert comments about this?

Is this a production or a development environment? If an object isn't being used then it's not necessarily a problem (performance wise) unless it's cluttering up either your dictionary or raising concerns in regards consuming unnecessary space. Personally I'd recommend that it's better to tune what is being used / taking resources. It may be a once a year report or some old utility pulled out once a year, best check why these things are there.
If you go down the dropping route, rather than drop anything immediately lock accounts for an agreed period of time to make sure that the schema isn't used & check any references from other schemas to objects within the schema that you're planning to drop, potentially audit these to check whether they're being called by other schemas / checking dba_dependencies between schemas & objects using a hierarchical query to check sublevels.
There are also quite a few Oracle standard components that are installed by default that have interdependencies and won't necessarily be used in the dictionary (checking dba_features_usage_statistics)

How much memory can Premiere Pro use on a new Mac Pro?

I'm ready to upgrade memory on my Mac Pro Late 2013 6-core. Does PP CC 2014 have a limit on how much RAM it can use? Some apps never use more than a certain amount, so I don't want to buy a lot of memory if PP will never put it to work. (I made that mistake when I was an FCP user.) Is there a limit and if so, what?
Also, are there any Mac Pro users who have an opinion on optimum RAM? I currently have 16GB (4x4GB) with 10GB reserved for PP. I am in the middle of a very large project and have noticed some irregularities and spinning balls. I assume that they are from memory shortage since quitting all other apps and restarting PP seems to fix the issue.

Not a Mac expert here ... but I do know there's folks running 64G ram and so going up from 16 will work fine. Now ... as to which is the "choke-point" ... that's a bit more techie than I can answer off the bat.
The Adobe video apps can put a pretty good strain on all of the computer's hardware, and "balancing" the assets of the hardware to the usage patterns of the software is always the trick. Memory never hurts ... but if the spinning ball is a video-ram problem, changing mobo ram isn't going to do much. The various areas they go into great detail on within the pages of the "Tweakers Page" (found within these forums threads, check the hardware forum) are of course, mobo, chip/s & cores, ram, disc in-outs & arrays/layout of project/footage & program files, video card & ram.
Your problem might be best solved by more RAM; it might be that it's a disc read/write issue and either more internal or eSATA II discs to spread read/write processes over would be best ... or taking an array of discs and using a fast multi-disk RAID array to speed things up even faster, or a video card upgrade.
So ... where you might want to go is the the Hardware Forum and give your computers complete specs, including disc layout and usage, and see what folks there think needs tweaking.

How do I find how much disk storage is being used

Being new to Apple (McBook Pro) and an old user of Windows I'm seeing some of the differences and reasons for the change, one of the differences is to see the disk usge. How I can achieve this in Apple?. I know thats is simole but ai cnay find it. Thanls

How much memory can Audition make use of

I am considering a new computer. If Audition 3.0 will make use of ram in excess of 2 MB I will put it in. However, the "system requirements" gives only the minimum and does not suggest optimum. Many programs will not address ram in excess of 2 MB.
Does any one know?

Yeah, what Runaway said. That's what I believe anyway, based on my own occasionally painful experience running Au3 on P4 1.7 Ghz with 2 GIGs of RAM. Things start to stutter and crap out when I get over twenty tracks running in Multitrack with realtime EQ running on everything and ESPECIALLY compression running on only a few tracks.
My next purchase is going to be a new computer, dual core with tons of speed and real estate.

How much memory/space are Mac Apps Taking?

I know this is probably a very simple question for you experts but as a newbie, I dont know how to figure it out. Im trying to find out how much hard drive space (and maybe memory?) the apps I have downloaded from the Mac App Store are taking up? Where would I find this? Ive looked in the Finder but couldnt find what I was looking for? Does the Activity Moniitor or something else break it down to just the Mac Apps?
Also do you know if Time Machine saves your organizational Launchpad Folders when you back up your machine? Just was curious if you had to switch macs or something, if the folders would all come back up or if its best to keep a list of what apps you have in what folders.
I also was wondering if anyone else has had a problem of your Launchpad Folders and individual apps within folders getting out of order when you have to restart your system. Since I dont yet have an iphone and apps were new to me, I got a little crazy in downloading a bunch of free apps and games (many of which I think Im going to start deleting because I dont really use them)...but Ive organized them in all in alphabetical order - Ive got folders in Alphabetical Order as well as the apps within folders in alphabetical order. Its strange becuase whenever my system gets restarted, several of the folders and apps get mixed up. Ive been working with Apple techs on this for weeks but just curious if anyone else has had a similar problem. The tech told me most people dont keep it as well organized as I do.
Thanks.

You can do this:

To find out how much hard drive space (or how large the App is), Right-Click on the App in your Applications folder and choose Get Info. This will show you xx MBs on Disk (hard drive). To see how much memory the App is using, check Activity Monitor while the App is running. It will be on the list of all processes running.
But you can also click the  (apple) in the upper left hand corner of the screen and select about this mac>more infor>storage

How much memory does SQL Server 2008R2 Standard use on Windows Server 2008 R2 64-bit?

Hi,
can anyone tell me how much RAM will really be used by SQL Server?
72 GB are currently installed. As Windows is only able to use 32 GB is SQL Server able to use the other 40GB + the unused part of the first 32 GB?
Thank you very much!
BR Matthias

Sorry, I don´t understand your post ?!
Maybe the question is if SQL Server is able to allocate more memory than the installed Windows Version is able to?
Since your OS is Windows Standard edition(X64) it cannot use or a process running cannot use more than 32 G of memory.
Now SQL server can use as much memory possible but it is now limited by Windows as your OS can only see 32 G.So it would be good part from your side to go to sp_configure and set 25 G for SQL server and can leave rest for OS( it just a figure not a actual
value i have given,actual you have to calculate by yourself or refer to below link) .
http://mssqlwiki.com/2013/04/22/max-server-memory-do-i-need-to-configure/
As Andrew said after 32 G what ever memory you put it is waste.
Hope this helps

How much memory do Objects use?

I'm not sure how to ask this, but how does java manage memory usage for multiple objects? Is the memory needed for a classes methods shared amongst the objects of that class, or does each object have memory for it's methods allocated for its use alone?
For example:
class Foo {
public void doSomething();
}Let's say I have 30 instances of Foo. I can think of 2 options (but I maybe wrong)
Case A: Each instance of Foo has it's own memory allocated for it's own copy of doSomething(), resulting in the total memory
usage of 30 instances of Foo being about 30 times how much memory 1 Foo uses
Case B: Each instance of Foo looks at a common copy of doSomething(), resulting in less memory needed since there is only one copy of doSomething in memory.
If the case is A, Static methods would seem to be potentially more memory efficient. Assuming my thinking is correct(and feel free to say I'm dead wrong), would it not make sense to make as many functions as possible static?

jverd wrote:
Executable code (initializers, methods, constructors): One copy of the bytecodes per ClassLoader that loads the class. Static/non is irrelevant.Seems to answer the question in full.
With reference (no pun intended) to the subject.
Instance variables (non-static member variables): One copy of the variable per instance of the class. Stored on the heap.
Class variables (static member variables): One copy of the variable per ClassLoader that loads the class. Stored on the heap.
Local variables, including parameters: One copy of the variable per invocation of the method.Just to complete the picture a bit (but NOT to contradict earlier comments).
Primitive variables - as above.
Reference variables - as above. Note that method local reference variables are stored on the stack but
any object instances referenced by these are stored on the heap even so.

HT3939 How can I find out how much memory is used to run the iphone 5c and the 5s ?

How or where can i find out how much memory the OS iphone 5c and installed apps. use? Then to find out how much memory the apps i plan to use uses? THANK YOU ALL. I HAVE A PURRING KITTEN IN MY ARMS.

Hello comodotomi
If the app is in iTunes, you can get information on what Apple ID was associated with the purchase. The steps to do this are outline in the article below.
