Is useing swap space and hibernation secure?

As I understand it when you hibernate your system the ram is written to the swap space and the computer powers down. Is this secure and encrypted?

No, it is not. But are ypou running arch from an encrypted filesystem? Otherwise it would be pojntless. Anyway the normal swap is not encrypted either, at least by default.

Database Instance Using Swap Space even When There is Plenty of Free RAM

Hi,
I am facinga strange issue in oracle on solaris 5.10
Platform:solaris 5.10
Database version:11.2.0.1.0
Our database Instance Using Swap Space even When There is Plenty of Free RAM.
We have 80GB of physical RAM, 32GB is set to oracle SGA_MAX_SIZE
memory parameters:
memory_max_target big integer 32G
memory_target big integer 32G
sga_max_size big integer 32G
sga_target big integer 32G
but still oracle is taking memory from swap even though we have enough physical memory.
please find the top output

I refered the metalink document id: [ID 761960.1]
Database Instance Using Swap Space When There is Plenty of Free RAM metalink note [ID 761960.1]
and tried the disabling the sga_max_size and memory_max_target and memory target with all different combination but no use.
We have one more box where same setup was configured in solaris platform but there the above memory parameters are not disabled but it is not using swap space it takes memry only from physical RAM
Can any one throw some lights on this issue. It wopuld be great if I come to know where the exact problem
Thanks in advance

Hi,
I didn't say I am not using 11gr2 memory parameters I am using all the automatic memory parameters but the thinks is as per the metalink note I tried by disabling the automatic memory parameters. but that didn't help me in preventing unnecessary swap usage. So I reverted. now it is using automatic memory parameters.
so What is the solution for this?

Observation: SAP uses swap space even when OS has available unused memory

Hi Folks,
   It is my understanding that any memory not used by the Linux OS itself or the SAP application is available for Linux to use for I/O buffers and file caching. When the SAP application requires more memory I would expect Linux to take memory away from itself (release I/O buffer and/or file caching memory).
   We have observed that SAP uses swap space even when there is memory available. Is there some feature in SAP kernel or some ABAP construct that causes SAP to prefer swap space over available memory? Or maybe there is a Linux kernel setting that influences SAP's use of swapping.
Regards,
Zaz

Hi Mike
You did not mention which distribution you have. Under SLES there is is a parameter called SWAPPINESS, which controls the buffering/swapping.
cat /proc/sys/vm/swappiness
If you don't already know, you can see the memory usage with the free command.
root # free -m
             total       used       free     shared    buffers     cached
Mem:          7987       7901         85          0        364       4262
-/+ buffers/cache:       3274       4712
Swap:        15999          0      15999
As far as i know, in this example 3274 is memory used by SAP and other processes and 4712 is cache. Please correct me if i am wrong.
Regards
Michael
Edit: a low swappines, for example 10 means to reduce cache first, a high swappiness (example 100) means page out processes first

Swap space and tempdb

Hi,
I'm having RAID 1 and RAID 5. RAID 1 is partitioned into 3 drive letters, C, D, and E. RAID 5 got only 1 partition, which is drive F. C for OS, D for SAP Kernel, E for Transaction Log and F for SAP Data.
In which drive should I allocate for swap space and tempdb? Of course for better performance I should have got separate hard disk for these, but unfortunately I can't.
Any suggestion.
BTW, my platform is Windows 2003 Enterprise and SQL Server 2005.
Rgds,

Dear Hapizorr,
I recommend you review this document developed by Microsoft specifically for SAP systems:

How to find Oracle is using swap space or not?

Hi,
I have a SuSe Linux database server on which 2 Oracle 10g databases and one MySQL server is running.
I can see a very little swap space is being used in the server while there is almost 100% RAM utlization.
I want to know if my Oracle databases are using swap or not. If it is using, how much of swap being used currently by each Oracle database?
Can someone please guide me on how to do that?
Thanks in advance for your help.
Regards,
Murali Mohan

I did "vmstat 1 10" and here is the output.

How is SWAP space and Oracle's Shared Memory related ?

MEMORY_TARGET not supported on this system
I gathered that In Linux, if you want to set MEMORY_TARGET, MEMORY_MAX_TARGET to nGB , then you should have a SWAP ( /dev/shm ) of nGB.
My Swap was only 16gb and I was trying to set memory_max_target to 20g
$ df -h /dev/shm
Filesystem Size Used Avail Use% Mounted on
tmpfs 16G 7.2G 8.6G 46% /dev/shmNow, I am wondering how is Oracle's Shared Memory (SGA+PGA) related to SWAP space in a server ? Shouldn't Oracle's Shared Memory be related to Physical RAM rather than disk based SWAP space ?

related question:
In the above mentioned OTN article it says ,
You could encounter ORA-00845 if your shared memory is not mapped to /dev/shm
I think he meant
You could encounter ORA-00845 if your SWAP space is not mapped to /dev/shm .
Am I right ?

Used a space in setting security code, now cannot ...

I recently upgraded my phone and got an N8. When I got the phone, as usual I changed the security codes on it to suit. Here's my problem, maybe someone could help me.
I changed the security code on my phone to a new code, but the new code I chose uses a space between two words and the phone accepted this no problem when setting the code. Now, after being asked to enter the security code on the phone after a soft reset after a crash, but on the alpha numeric keypad there is no way of inserting a space into the entered code. 0 does not give a space, only a zero.
Anyone, any ideas on how to get around this.

@Aspergerguy.
Thanks for the reply mate, wasn't sure if anyone had ever come across this problem before. When I set the code, it accepted the following "lone liveman". If it only stores the first 5, I'm kinda screwed anyways because the space is the fifth digit. It's unusual that it accepted this when a space cannot be entered in the keypad for the code. Normally when characters aren't acceptable they're refused when setting up, not afterwards. Anyways will probably just upgrade to a samsung as the centre where I live in Ireland are locally known as ripoff merchants and I don't trust them not to over charge me.
I'm also useless in holding onto reciepts etc, so would have to go get a reprint from the purhcasing store, this is no problem, but would you know, if I do bring it to a repair centre, can they read the actual set code as above? and wouldn't this stand as proof of ownership as the security code can only be set on a functional phone.
Once again mate, thanks for your speedy reply

Using Swap space

Hi All
I have an application consisting of lots of processes. When ever I start my applicaiton, I seem to be running out of swap space. I see that there is a lot of reserved space. Means the applications are attaching shm and/or requesting mallocs. Is there any way to fix this, either by debug by some mem tool or by any compiler options? I am running this on Solaris 10 with binaries compiled in sun studio 11 compiler set.
Thanks in advance.

Hi All

processes. When ever I start my applicaiton, I seem
to be running out of swap space.How are you viewing this?
I see that there is
a lot of reserved space. Means the applications are
attaching shm and/or requesting mallocs.Also, just the forking will need to reserve space as well.
Is there any
way to fix this,I don't see that anything is broken. What are you trying to fix? You need memory to run lots of programs. Have you tried increasing the swapfiles on the machine? That will handle increased reservation requirements.

SWAP space and RAM size

Hi all,
However there is no specific measurement for providing SWAP space,there is a ganeral rule says that "SWAP space must be twice the amount of RAM"...Why this specific value(twice of RAM)..Why it cant be the thrice amount? May i know what is the reason for telling this rule?
Please can anyone tell me?
Jasmine

Hi
The minimum requirement should be twice the size of RAM.This is because when a core dump occurs the whole active process avaulable in RAM will be written as a core file .the file will be initially written in the swap.The swap has to hold the full amount of memory and inturn swap will also have some files active.So as a minimum requirement you should have twice the amount of RAM as Swap Space.If you have a high storage and you dont know what to do give to to swap,No issue in that.

Difference between used disk space and folder space

My startup harddrive (an SSD) info gives that 88 GB are used. If I open it in OS X and look at info for all the folders in it, their summed used space is 24GB. Thus 64 GB are used to unknown purpose and cannot be used.
This problem seems to appear from using migration assistant to transfer from my old mac to a slightly newer. Both running Yosemite 10.10.1. I had to shutdown the migration because the computers seemed so lose contact with each other and the end of the migration seemed to go on for ever.

Photo sizing for optimum use of space and quality viewing and downloading

Greetings!
I am curious about photo sizing in iWeb.
I understand that if I drag a photo into a media placeholder (such as the blog pages), that the photo is automatically re-sized for that drop zone. (Is that correct?)
If I drag a picture to a spot on a blank page, and then drag corners to make the picture appear the size I want it to be, is the picture condensed to the necessary size digitally so that download and storage is appropriate?
Any knowledge shared will be so appreciated! My site will eventually be pretty bulky, so I need to start this out right, and not have 5 MB pictures on there if I only need KB pictures.

Silly me. I answered my own question--I tried it, and then right clicked on the pictures from the browser, and it resized my 5 MB pictures down to 35 KB and they look great.
How freakin' easy!
I love this mac!

How do I keep Warp Stabilizer and aeselflink from filling my swap space?

Hello,
I'm running the lastest version of AE on OS X, when I try and run warp stabilizer on a composition, aeselflink grows the virtual memory it uses (> 50GB) until it fills my swap space and causes my machine to hang, because the hard drive is full.
Running AE's Edit->Purge options has no effect on the amount of virtual memory used. I have to quit AE to get aeselflink to quit and free the memory used. How can I limit the virtual memory used by aeselflink to something reasonable?

I'm not aware of a way to control this in any more detail, but this stuff obeys the settings you make in the Render Multiple Frames Simultanuously prefs if used. Otherwise it will use factory defaults which should never use more than 4GB. Anyway, the behavior you see is highly irregular no matter what. Sounds like a memory leak, so maybe you can provide more info, including which AE version, what footages etc.

GWTDOMAIN using lots of swaps space in WLE 4.2!!!

We are having problem in one our of non- production environments where the GWTDOMAIN is using lots of swap space and not releasing them. It got so bad that the swap space used was 100% and we had to "kill -9" this GWTDOMAIN and bounce it again to to release this space. Is this a known bug and if not what can I do to resolve this problem
or do we need to open a trouble ticket with BEA to fix.
Thank for your help.

Difference between page file and swap space

Hello friends
What is difference between swap space and page file???
I set the page file to 0 MB(No page file) but when I use Everest Software it show 1023 MB swap Space.Is there difference between them?

Swapping meaning data in and out from memory ie. primary to secondary. Paging is also the same thing, but its mostly used nowadays as virtual memory is based on pages. So, its like pages in and out. Swap space the memory used for swapping entire processes
from system memory into the swapfile. Where as paging transfers the pages to page file when the memory is almost full.
Regarding Everest, I think you should check with the supplier.

Arch process using more swap space

Hi,
DB : 11.2
OS : Aix 6
While taking archive backup by oem,only 9 archive process consuming more swap space.
The parameter value is LOG_ARCHIVE_MAX_PROCESSES=15 at db level.
Why only 9 archive process use swap space at os level?
how to determine all the archive process needed?
Thanks & Regards,

Physical memory 120 GB,Swap space 45GB.
We getting TOP consuming SWAP space PID's from OS team.Then we checked v$session with that PID's.We found that PID's belongs to archive processes.
Nealry 25 log switch per hour happened.the log file size 8gb,8 groups. Then REDO log files is is way too small by around a factor of SIX
Increase REDO log file size to 50GB to reduce the number of switches per hour to around 3 0r 4.
