You might want to look at
http://www.puschitz.com/InstallingOracle10g.shtml
however more info on your configuration is necessary. BTW, you can also
improve performance by spreading the swap over different disks.
HTH.
Paul...
When asking database related questions, please give other posters
some clues, like OS (with version), version of Oracle being used and DDL.
Other trivia such as CPU, RAM + Disk configuration might also be useful.
The exact text and/or number of error messages is useful (!= "it didn't work!"). Thanks.
Furthermore, as a courtesy to those who spend time analysing and attempting to help,
please do not top post and do try to trim your replies!

Problem on Creating a Swapfile for adding swap space

Folks,
Hello. I am using Oracle Linux 5.6. At this time, the Linux swap space is 0 KB by using the command:
[root@rac1 /]# grep SwapTotal /proc/meminfo
I need 150MB swap space to install Oracle Database. I create the swap space using the following commands:
Step 1:
[root@rac1 /]# dd if=/dev/zero of=/swapfile bs=1024 count15360 hit enter
Output: 153600 to records in
153600 to records out
157286400 bytes(157MB) copied, 3.3835 seconds, 46.5MB/s.
Step 2:
[root@rac1 /]# mkswap /swapfile hit enter
Output: Command not found.
Step 3:
[root@rac1 /]# swapon /swapfile hit enter
Output: Command not found.
Step 4:
[root@rac1 etc]#vi fstab
Add this line into the file: /swapfile swap swap defaults 0 0
Save and close the file fstab.
Step 5:
Reboot Oracle Linux 5.6 and run this command:
[root@rac1 /]# grep SwapTotal /pro/meminfo
Output: SwapTotal: 0 KB
As you see above, swap space is not added. I think the problem is that the commands "mkswap /swapfile" and "swapon /swapfile" are not executed.
My question is : Do any folk understand how to add the swap space successfully ?

When you execute a program, the command shell will walk through the locations specified by $PATH environment variable in order to find it. The "./" path is the current working directory and should not be in the $PATH environment to make sure applications are run only from locations defined by $PATH and not the current working directory. You can bypass this behavior iif you specify the full absolute path to the program at the command prompt, e.g. cd /sbin, ./mkswap or /sbin/mkswap. Other programs and administration tasks will use Linux utilities located in /sbin without specifying the full path and will not work if /sbin is not part of your PATH environment.
You may have seriously screwed up your system because your root account contains /home/ora11g/bin, which is normally defined by .bash_profile located in the user account's home directory. Before analyzing your login scripts, I suggest you post the output of the following command:
cat /etc/passwd

Swap Space in Linux

Hi,
I am newbie to Linux.How to increase the Swap Space in Linux for Oracle 10g Installation.Is it possible to create the Swap space without Reboot in Resue Mode.Tell some commands about Swap space and File system.
Thank You,
With Regards,

1. Find a filesystem or partition on which you want to create swap space. Lets say root filesystem /
2. Example -> dd if=/dev/zero of=/swapfile bs=1024 count=65536
3. Making of swapfile -> mkswap /swapfile
4. Immediately enable swap -> swapon /swapfile
5. To enable it at boot time edit /etc/fstab to include -> */swapfile swap swap defaults 0 0*
Finally Check with you Unix system administrator before doing these commands.

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.

Swap space

Hi
I intend to install oracle 10 R2 on redhat linux 5 , my system have 64 gb ram
how much swap space i need to setup for this size of ram
i check some installation docoment it mention
if the memory is 1 to 8 gig then it should be double
if it is more than 8 gig then it should be 0.75 of mrmory size
if this is the method then for my ram size i need to set 48 Gb
is this is right size , i am wondering this size seems like very huge size
pls advise what is the right size for 64 gb RAM
RDS

The documentation states:
http://download.oracle.com/docs/cd/B19306_01/install.102/b15667/pre_install.htm#i1011296The system must meet the following minimum hardware requirements:
swap space ... More than 8192 MB -> 0.75 times the size of RAM>
So, probably it will work with less memory but if you want a supported configuration, then assign the required space, hard disks are so cheap.

Swap space/dump devices for large RAM systems

We are in the process of changing our standards for our server builds and need some input. Currently, we match the swap space on local disk with the size of RAM. I know this isn't necessary for "swap" any more, but we use the swap area as the dump device as well, so we are sure to have enough space there to contain a full memory dump if the server crashes.
Now we have systems coming in with 128 or even 192 GB of ram. They contain only two disks (146GB), which we mirror. Obviously there isn't enough space on these disks for 192GB of swap or a dedicated dump deivce.
We need the ability to capture full dumps when we have a crash, probably with a dedicated dump device. Should we start ordering SCSI disk enclosuers for this purpose? Can we make a SAN volume our dump device?
What is everyone else doing with these larger RAM systems?

Compressed dumps have been supported in UNIX flavors for many years, so you need to dig further into it. It is supported in linux, so I can't imagine why it wouldn't in Solaris. Tru64UNIX, HP-UX, AIX, and others all provide this capability.
True, you can't get internal disks bigger than the 146 on Sparc platforms, but you could attach a "boot array", like a storagetek D240 system, or iScsi or fiber attached storage. The only caveat is whether Solaris, in the throes of a crash, still has the drivers loaded that can address an external disk subsystem. That would have to be investigated with SUN. And these arrays support the new 1TB SATA disk drives. We are deploying 6140 shelves with 16TB per shelf. Simply amazing...

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 ?

Excess Swap Space....

Hi all,
Please I would like to find out if large swap space has any effect on the performance of a Server.
Thanks

No. Generally not a good idea.
Oh, details? Sure.
To begin with you do <u>not</u> want any active paging going on; it kills performance quickly. It is normal to see some memory pages being evicted to paging store; the kernel does some proactive evictions of stale memory pages just in case the room is needed sometime in the future.
$ top -n1
top - 07:37:55 up 3 days, 19:58, 1 user, load average: 0.01, 0.82, 1.26
Tasks: 302 total, 15 running, 287 sleeping,   0 stopped,   0 zombie
Cpu(s): 4.5%us, 6.2%sy, 0.1%ni, 88.2%id, 0.8%wa, 0.0%hi, 0.1%si, 0.0%st
Mem:   6902244k total, 6486860k used,   415384k free,   600968k buffers
Swap: 8392696k total,    14496k used, 8378200k free, 1290552k cachedThe swap utilization reported by top(1) is misleading because it shows a static picture of how much swap space is being used. The problem is that you can't distinguish between the stale-memory evictions and the unwanted paging activity. Better to use the vmstat(1) tool for this:
$ vmstat 1 3
procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu-----
r b   swpd   free   buff cache   si   so    bi    bo   in   cs us sy id wa st

It is OK for this to show some minor values, but should the count increase rapidly for some time you should regard this as a sign of swap activity and fix it.
Lots of installation documentation suggests that the size of paging store be at least equal to the physical memory size or even larger. On anything much larger than an old desktop this is simply too much space: the system will become unusably slow long before this amount of space is utilized.
Ancient history: at one time some UNIX ports used the swap space to temporarily store a memory image of a system oops. Every boot, the kernel checked the swap space for a special signature pattern to see if the swap space held such an image.
Back to the present: having an excessively-large paging store simply wastes disk space. Sometimes the extra paging store can be useful to have because it can postpone a Linux out-of-memory (OOM) kill by the kernel if you have a run-away program leaking memory, but most likely this simply trades an OOM kill for really poor performance. Your mileage may vary, as they say.

Swap Space Recommendations

Hi,
Is there a recommendation when it comes to setting the swap space for the system running the endeca server?
We are using EID 2.3 on Linux.
Our machines are currently freezing once the swap space gets consumed.
Thanks,
Will

Will,
Is the machine running Endeca Server also receiving incremental updates or does your solution operate as more of a "kill and fill" operation where the index is being fully loaded each time?
Some other information that would be helpful would be the size of your index and the amount of RAM available on the machine. If you're not comfortable sharing that, a ratio would also suffice (i.e. I have 48GB of RAM and my index size on disk is 12GB so the ratio of RAM to index size is 4:1).
Typically, I've seen the "high water mark" of addressable memory reach about 2 to 2.5x the index size. Keep in mind that it only ratchets up to that level on rare occasions when an index that has been in use for a while (warm cache) is in the final stages of a bulk update, the usual running amount is much lower. And of course, swap should only come into play when your available memory is constraining the system.
Hope that helps,

Swap space for multiple instaces on the same box

OS: Oracle Enterprise Linux 5 Update 2 (64-bit)
DB: 10.2.0.4
I'm fairly new to Linux and have a general question about configuring swap space on a Linux box running 10g. From the 10g: Managing Oracle on Linux for DBAs class, Oracle gives the following recommendations about swap size:
RAM (Swap)
<= 2Gb (150% of the RAM size)
Between 2Gb - 8Gb (Equal to the RAM size)
8Gb+ (75% of the RAM size)
It's not clear to me from reading the book if this recommendation is good for all Oracle processes running on the machine, or if it's a per instance value? The box has 16Gb of RAM but there are going to be three instances running on it and I need to verify that 12Gb of swap will support all three without issue or if I'll need to configure 12Gb swap per instance.
Appreciate any input.

As noted earlier in this thread, swap space is an operating system property, and has nothing to do with software you want to run on top of it, like an oracle database.
The function of swap space is to be able cope with memory allocations beyond the amount of physical memory. In most occasions you do not want to use swap space, because it has a severe performance impact (memory blocks have to be exchanged from the swap device to physical memory).
(please mind that on some unixes (AIX and HPUX if I am not mistaking), swap is pre-allocated for processes which means the swap size is not only depended of operating system and memory size, but also the number of processes. Linux does not do that, it starts to allocate swap pages under memory pressure. There are certain issues with some memory settings in linux (linux kernel memory management is quite automatic) that can get your system to page. (memory overcommitting is one thing))
In my experience, the amount of memory which is used is depended on the amount of memory on the machine in most cases. Whilst this sound simple, think of it: with 2GB used, probably most DBA's would allocate approximately 1.5GB to the databases on that machine, if your machine got 16GB you probably want approximately 14GB to be used by the databases.
This means (for me) that I use swapspace with the same size as the amount of memory. That few extra GB's allocated to swap won't cost you or your company an arm and a leg, so have that for not running out of memory.

Swap space problem on Windows XP

I'm trying to install BI Publisher on Windows XP from a zip file downloaded last week (version 10.1.3.3.2). However after starting setup.exe in the install directory I get the message that my swap space = 0 Mb while 500 Mb is required. After this the installation procedure quits.
I haven't got a clue as what the installer is referring to (swap on windows?) but I have plenty of room om my two (logical) disks, no spaces in the directory name from which I start the installer (D:\download\bipublisher\Windows\OBI\install) and about 1.5 Gb of memory free.
Any hints what to do would be appreciated.

Hi Mjb001,
In computer operating systems that have their main memory divided into pages, paging (sometimes called swapping) is a transfer of pages between main memory and an auxiliary store, such as hard disk drive.[1] Paging is an important part of virtual memory implementation in most contemporary general-purpose operating systems, allowing them to easily use disk storage for data that does not fit into physical RAM. Paging is usually implemented as a task built into the kernel of the operating system.
Windows 3.x creates a hidden file named 386SPART.PAR or WIN386.SWP for use as a swap file. It is generally found in the root directory, but it may appear elsewhere (typically in the WINDOWS directory). Its size depends on how much swap space the system has (a setting selected by the user under Control Panel → Enhanced under "Virtual Memory"). Please check this file.

Currently we have a issue of swap space getting used up nearly 100%. The system was out of memory and can't run any applicationThat is unusual and should not be happening when you have what seems to be an excess of memory available. This could mean some kind of bug (memory leakage for example), or it could mean plain old fashion abuse of memory. Like PL/SQL code that attempts to bulk fetch a few million rows from the database with a single go.
On checking Metalink note, it said its an unhandled Oracle exception; have to increase the swap space.Wrong IMO (unless you were not following the recommended swap size factor). If you have have a giant swap area..moving the wall a few meters away (by increasing swap) will only enable you to run faster into it - I doubt that this is the intent of that Metalink note.
On increasing the swap space, and restarting the instance, the system was normal.
Now why does oracle use up all the swap space and what can be the workaround to avoid this in future?Oracle only use what is needed to perform the client requests that it receives. If the client request a mountain of data to be moved/processed, Oracle will try to oblige. If that mountain topples and crushes server resources, it is not Oracle that is to blame for trying to do exactly what was requested from it.

Hi
Out of memory they can result from different causes:
- The application is consuming too many resources inappropriately
- The application is opening and not enough threads are closing, leaving no space for the JVM
- You lose the connection with database, causing the connection pool is saturated, which makes the memory of the container is depleted and reaches its peak.
- The container does not have sufficient resources or is not tuned to meet the load generated. But would recommend to discard the above before using this option, because when using this option could work around the problem but could not really be attacking the cause.

Swap Space error in pre requisite check of NWDS2004(Support Pack18)install

Hi,
Trying to install NWDI SP 18 (SAP Netweaver Developer Workplace ) trial version on my machine with Windows XP.
The installation (after installing J2EE Engine + MaxDB + NWDS 2004 etc), it has thrown some error regarding page size.
So when we check the pre requisites for the installation of the software, it is giving the below error that the swap size needs to be increased.
==============================================
Condition:- Swap Size
Result Code:- Condition not met
Severity:- HIGH
Message:- For the selected services atleast 7135 MB swap space recommeneded.Current value 3921 MB(updated 2005-06-24)
=============================================
Please anybody let me know if there is a way to increase the swap size and fix the issue at the earliest.

Hi Gandhi,
Right click my on computer ->Select Properties -> Click Advanced Tab ->Click Settings (performance) -> Select Advanced Tab -> In virtual memory -> Change ; You canIncrease swap space/page file here.
regards
Juan

Available swap space problem in solaris 10

Dear All,
Currently I am facing a most interesting problem regarding swap space.
We have assigned mirrored slice swap space with 20G size. But when we are asking for swap space it is only showing around 2GB.
1. Please have the swap area:
root@palash # swap -l
swapfile dev swaplo blocks free
/dev/md/dsk/d1 85,1 16 41945456 35002784
root@palash # swap -s
total: 53562072k bytes allocated + 5689008k reserved = 59251080k used, 615704k available
2. Please have the metastat output:
root@palash # metastat d1
d1: Mirror
Submirror 0: d11
State: Okay
Submirror 1: d21
State: Okay
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 41945472 blocks (20 GB)
d11: Submirror of d1
State: Okay

Stripe 0:
Device Start Block Dbase State Reloc Hot Spare
c0t1d0s1 0 No Okay Yes
3. Here is /etc/vfstab entry for swap:
/dev/md/dsk/d1 - - swap - no -
4. But when we checked swap space using df command:
root@palash # df -h

Please help me to indentify the reason.

Hello,
Thanks for your reply.
But I am not clear about your findings as we have around 64GB physical RAM in my machine.
My question is that if we mount 20GB swap partition, then how we can see this is around less than 2 GB in df -h command.
And even in swap -s command, this is showing same problem.
What might be reason behind this????
//PalashWell no-one else has anwered ... so its back to me.....
Hmmm ... i would use the word observations rather than findings .... I am not on an old root explotation expedition all over our server .. merely observing on the morsels you show me ....
Please be aware I may not be totally technically correct or be using right terminology on what follows so I welcome corrections ....
Your machine has 64GB Memory, and a 20 GB swap file, therefore has the ability up to support 84GB total (Virtual) Memory ofr it's processes/buffers.
The reason little swap is free (let us say 2GB ... thoug it may be 600m) is theat processes/buffers have a virutal memory requirement of 84GB-2GB = 82Gb.
... So rather than wondering about how come 2GB is left, start thinking about ow 82GB is being used.
...... Particularly with databases oracle RDBMS; mysql etc a big influencing factor can be how much memory is allocated its memory structures.
.......... And a DBA may set these extremely high (memory_max / innodb-buffer-pool-size etc etc).
ps -ef will show the (virtual) 'size' for individual processes
prstat -a may help show what is going on (but may double account some things):
ipcs -a would show the allocation for the oracle RDBMS memory_area,
echo ::memstat | mdb -k ### may help ... but i have seen accounts of it taking ages to run.
I'd also check kstat zfs ... but your not using zfs so no need to bother.
.... You may need to show some evidence of how your applications are consuming virutal memory for someone to help you futher ... but if you do htis who may answer your own quesiton.
