How to get the amount of free physical memory?

How to get the amount of free physical memory?
(without sudo or root)

vmstat will give it to you.
Although the question depends a bit on what you mean by free memory.
The figure vmstat labels free (in any reasonably recent version of solaris) actually represents memory mostly filled with cached file contents. So it represents memory that can be easily released if needed by something more important.
Like most unix versions, solaris will use any free memory to cache files thats have been read/written previously just in case they are needed again

How can I get the amount of free space that is on my drive to show at the bottom of the drive in Lion.

How can I get the amount of free space that is on my drive to show at the bottom of the drive in Lion.
This is a must feature for me and I may have to go back to Snow Leopard.
Please help!

Right click on your desktop and choose "viewer options". Adjust the spacing and the size of your icons and you should be able to see the size of your drive(s) and the free space available on each drive with the exception of your bootcamp drive which will only show the overall size of the drive you have it on. This may be different if you only have one system drive (like on a Mac Book Pro) with a partition containing bootcamp on it. this may only show you the overall capacity, I can't say for sure though as I only use a Mac Pro with 4 seperate Hard Drives which are showing both overall capacity and free space available. Hope this helps

Upgraded to IO6, seems like the amount of system memory to run is higher, this causes issues with some Apps. I can't get SIRI to work because the amount of free system memory is not enough. how can I tell what is eating the system memory?

How Can I Get the Amount of Free Disk Space Using space using windows 7 please share example using GetDiskSpace

How Can I Get the Amount of Free Disk Space using windows 7 please share example using GetDiskSpace i have already studied http://digital.ni.com/public.nsf/allkb/9958B8E473C4EF1786256BBC0053B64F

Reading your question a bit more in detail, I doubt whether you are using Win32 API GetDiskFreeSpace function (for which my previous post is the solution) of Programmer's Toolbox GetDiskSpace function.
With reference to the second one, it works even with disks larger than 2GB but you need to use the proper formatting code to display the returned value. I updated my example to show total free space in the debug output window and added a comparison with 3GB value using UInt64TypeCompareUInt from the Programmer's Toolbox.

The amount of free SGA memory available in the database

Hi,
How can we calculate the amount of free SGA memory available from the instance if the database is not set for Memory management.If the sga_max_size is set for a particular value and the db_cache_size and the shared_pool and all other components are specified,how can one determine whether all the memory allocated for SGA is in use?

How can we calculate the amount of free SGA memory available from the instance if the database is not set for Memory management.When the SGA is allocated, the memory is fixed, and none of it is "free" really.
how can one determine whether all the memory allocated for SGA is in use? Are you asking about usage WITHIN the pools? If so, shortly after startup the database buffer and shared_pool will fill-up and stay full . . . . .
Here is the script that I use to see inside the data buffer contents:
set pages 999
set lines 80
spool blocks.lst
ttitle 'Contents of Data Buffers'
drop table t1;
create table t1 as
select
o.object_name object_name,
o.object_type object_type,
count(1) num_blocks
from
dba_objects o,
v$bh bh
where
o.object_id = bh.objd
and
o.owner not in ('SYS','SYSTEM')
group by
o.object_name,
o.object_type
order by
count(1) desc
column c1 heading "Object|Name" format a30
column c2 heading "Object|Type" format a12
column c3 heading "Number of|Blocks" format 999,999,999,999
column c4 heading "Percentage|of object|data blocks|in Buffer" format 999
select
object_name c1,
object_type c2,
num_blocks c3,
(num_blocks/decode(sum(blocks), 0, .001, sum(blocks)))*100 c4
from
t1,
dba_segments s
where
s.segment_name = t1.object_name
and
num_blocks > 10
group by
object_name,
object_type,
num_blocks
order by
num_blocks desc
Hope this helps. . ..

How to read the amount of free memory available?

I need a tool to tell me the amount of free memory left, at any given time. I want to tell my user in advance, and as the experiment proceeds, how much experiment time can remain before we will run out of memory. Yes I know, in a more perfect world the data would be written to disk and not stay in memory; but for now this solution would really help.
Please be clear: I'm not looking for the performance profiling tool. I need something that will tell my program, at runtime, how much memory is left available to it. Is there any such tool?
Thanks,
Ken

Hey Ken,
I think this article discusses what you're looking for:

How to get the amount of memory available programmatically?

Hello,
Out of memory is a very common situation occures in most applications. I was wondering if there is a way to find the amount of free memory available programmatically, it can atleast help a little. There are System class's functions but are not very full-proof. So can there be any other way?
THanks

Out of memory is a very common situation occures in most applications.Really? ;)

How to get the amount in local currency in GRPO transaction

Dear Frndz,
I am doing a GRPO transaction for a vendor whose currency is Euro.After making the transaction,will I be able to see the amount in local currency also? I know that it can be seen in the JV, but I want to see in the GRPO screen itself.
Regards,
SRini

Yes Srini you can do. You have to go GRPO screen currency field which will be under vendor reference No. field. Here you have to change local currency instead of BP currency. Now you can see row total as well as document total will be Local currency. But Unit Price would be Euro.

How to get the total number of pages printed in a report?

Hi All,
I have a requirement where I need to print a frame of fields only in the last page. Unfortunately I cannot use the 'Print Object On' property as it doesnt work in my case. So, I am planning to write a format trigger on the frame to return TRUE if the page is the last physical page. Now, I need to know how to get the total number of physical pages that will get printed in the report so that I can use this to manipulate the frame. I was planning to use the 'Total Physical Pages' built-in, but it seems like I can just use it to print in a field and I can't use this field's value anywhere in the plsql code (formula column function/format trigger) in the report. Is there anyway to get the total number of pages printed in the report which can be used in the report plsql code?
Thanks,
Srini.

i found the solution, thanks

Go to Settings>General>Usage. How much space does it show you have?
If you connect your phone to your computer, what does iTunes say is on your phone? Do you see a large amount of "Other"? If so, you may have a corrupted database. You'll need to sync your phone then restore it as NEW (not from back up) then re-sync your data).

How can I know the amount of free RAM when my VI is running?

I need to know the amount of free RAM when my VI is running.

If you are using Windows NT/2000/XP, monitoring free memory is very easy. Simply right click on the task bar and open the Task Manager. Click on the Performance tab, and you'll be able to monitor the physical memory total and available on your PC.
If you are using Windows 9X, you will have to add some optional resources. Open Control Panel, then select Add/Remove Programs. Click on the Windows Setup Tab, and select System Tools, then click the Details... button. Check the boxes to install System Monitor and System Resource Meter. Click OK, and you will be prompted for your Windows CD. Insert the CD and Windows will add the monitoring tools. You can then use them to watch your free resources.

Regarding: How to Get the Tax Amount

                       How to get the Tax amount for differnt tax type.
Please help me.

Hai Sakthi,
As you want the report for different tax types you can differentiate different tax types by tax rate and tax code you can refer the below query and modify according to your requirement and you can add as many tax codes/tax type based on your needs.
BASED ON TAX CODE AND TAX RATE :
SELECT distinct M.DocNum AS 'AR Inv. #', M.DocDate as 'Date', M.CardName as 'Customer Name',M.NumAtCard as 'Bill No. & Dt.',M.DiscSum,M.RoundDif,
(Select Sum(LineTotal) FROM INV1 L Where L.DocEntry=M.DocEntry) as 'Base Amt.(Rs.)',M.VATSUM,
t.statype,
(Select Sum(LineTotal) FROM INV1 L Where L.DocEntry=M.DocEntry and statype =1 and taxrate=5 AND TAXCODE='CHVAT5' ) as 'CHENNAI VAT5 SALES',
(SELECT SUM(TaxSum) FROM INV4 where statype=1 and TaxRATe =5 and DocEntry=M.DocEntry AND STCCODE='CHVAT5' ) as ' CHENNAI VAT5 COLLECTED ',
(Select Sum(LineTotal) FROM INV1 L Where L.DocEntry=M.DocEntry and statype =1 and taxrate=0.00 AND TAXCODE='CHTAXEXE' ) as 'EXEMPTED SALES',
(SELECT SUM(TaxSum) FROM INV4 where statype=1 and TaxRATe =0.00 and DocEntry=M.DocEntry AND STCCODE='CHTAXEXE' ) as 'EXEMPTED COLLECTED ',
(Select Sum(LineTotal) FROM INV1 L Where L.DocEntry=M.DocEntry and statype =1 and taxrate=14.50 AND TAXCODE='CHVT14.5' ) as 'CHENNAI VAT14.5 SALES',
(SELECT SUM(TaxSum) FROM INV4 where statype=1 and TaxRATe =14.50 and DocEntry=M.DocEntry AND STCCODE='CHVT14.5' ) as ' CHENNAI VAT14.5 COLLECTED ',
(Select Sum(LineTotal) FROM INV3 Q Where Q.DocEntry=M.DocEntry) as 'FREIGHT',
M.DocTotal as 'Total (Rs.)'
FROM OINV M LEFT OUTER JOIN INV1 L on L.DocEntry=M.DocEntry
LEFT OUTER JOIN INV4 T on T.DocEntry=L.DocEntry
LEFT OUTER JOIN INV5 J ON M.DocEntry = J.AbsEntry
LEFT OUTER JOIN INV3 Q ON M.DocEntry = Q.DocEntry
INNER JOIN NNM1 T4 ON M.SERIES=T4.SERIES
where (t4.series ='1' ) AND TARGETTYPE !='14'
GROUP BY
