Sga size in linux redhat

dear gurus,
we are using oracle 10g1, with rhas 4e5, where on clients end it is forms 6i with patch 17
now we set in the begining startup time 2048MB SGA size...we found we need to increase more we try to increase from EM web based but give us problem database not shutting down properly and even not starting up.
our physcial RAM is 4GB and swap partition size 16GB
can any one guide me how to increase safely SGA size...as when so many users works it start hanging application...then we have shutdown and startup
thanks and kind regards, any docs in details in linux for sga will be helpfull
salim shahzad

as when so many users works it start hanging application...then we have shutdown and startupmay be this is related with some other problem.also check ur hit ratio.because 2 g.b of sga is quite good on 4g.b machine,also check ur others parameters.
whats ur top command show when ur hitting the problem.

How much can go for SGA size in 32-bit Linux OS for 11i

Dear all,
I am looking for a better solution to my doubt from all the Guru's.
My requirement is that need to get minimum SGA size =10GB for my production system. At present my 11i application server and database running on Red Hat Enterprise Linux AS release 4 (Nahant Update 2) 2.6.9 42.ELsmp (32-bit) system with SGA size of 2GB with multi-node installation. Now we are planning to move from this old server to another set servers for production system with higher capacity.
Basically my requirement is that, for new server minimum SGA size=10GB in 32-bit linux OS, so please help me out to find the right solution.

How to decrease SGA size in oracle 9i

hi,
how to decrease SGA size .. now SGA size=400m i want to drecrease to 150m
Thanks,
Mohammed

Why do you want to do this? Is your system low on memory?
Perhaps your DB is on a laptop with
only a small amount of memory?
Well an enterprise database server set of
thread inside a complex service would need
a high powered laptop with large amounts
of memory.
Or perhaps your UAT server has 10 databases
on it all competing for resource?The culprit may not be Oracle.
For example (as you have not told us your operating system, windows linux unix?) IBM's AIX unix operating system comes configured optimally for managing file caching in the OS memory; as Oracle also caches the blocks read from disk sometimes the file system caching is redundant and ends up using memory better allocated to Oracle. In that case you tune the Unix kernel to reduce memory allocated to the file system caching. The default settings allow IBM AIX to take up to 80% of system memory for caching bad if you have allocated 40% to the SGA already.........
The really cool thing about AIX is you can do this on the fly and you don't need to reboot so when you go live you juggle until you get an optimal setting and then monitor.
In the end you may just have to add memory.

Database creation - SGA size

Hi all,
When I try to create a database using DBCA, My default SGA Size : 128. PGA:794. When I click Next button, I receive the following caution...
Following parameters do not meet the recommended minimum size requirements:
An SGA size of atleast 160MB is recommended
Do you want Database configuration Assistant to Change the Parameter? I gave ignore and I changed the SGA size to: 160, I received the bellow caution
SGA Size can not be greater than maxmimum shared memory segment size (1342177728). Refer to oracle installation guide to configrue your operation system kernel parameters.
Please suggest me on the same....
Thanks

Now I'm trying to create database using DBCA. By default my sga size allocated is 128MB. It recommends SGA size should be 160MB. I'm not able to extend SGA size. Please refere my previous post...
Could you please tell me why my default screen is showing as 128MB.
ThanksThe oracle installer determines the available sga_size bij calculating free "shared memory"
This is the setting of the maximum shared memory as posted in the first message minus the memory used by your first database, minus some other shared memory stuff.
To overcome this, you have to increase the mamimum shared memory size in your kernel and if needed reboot the system.
If your system happens to be a Redhat Enterprise system, then lookup the variable called
kernel.shmmax = <a certain size>
in /etc/sysctl.conf
Increase that value, and save the file ( as root )
Next run /sbin/sysctl -p to activate the new config

As per the Note
Maximum SHMMAX values for Linux x86 and x86-64 [ID 567506.1]
=======================================================================
QUESTION 2
===========
What is the maximum value of SHMMAX for a 64-bit (x86-64) Linux system?
ANSWER 2
===========
Oracle Global Customer Support officially recommends a " maximum" for SHMMAX of "1/2 of physical RAM".
The maximum size of a shared memory segment is limited by the size of the available user address space. On 64-bit systems, this is a theoretical 2^64bytes. So the "theoretical limit" for SHMMAX is the amount of physical RAM that you have. However, to actually attempt to use such a value could potentially lead to a situation where no system memory is available for anything else. Therefore a more realistic "physical limit" for SHMMAX would probably be "physical RAM - 2Gb".
In an Oracle RDBMS application, this "physical limit" still leaves inadequate system memory for other necessary functions. Therefore, the common "Oracle maximum" for SHMMAX that you will often see is "1/2 of physical RAM". Many Oracle customers chose a higher fraction, at their discretion.
Occasionally, Customers may erroneously think that that setting the SHMMAX as recommended in this NOTE limits the total SGA. That is not true. Setting the SHMMAX as recommended only causes a few more âshared memory segmentsâ to be used for whatever total SGA that you subsequently configure in Oracle. For additional detail, please see Document 15566.1, "SGA, SHMMAX, Semaphores and Shared Memory Explained"
==========================================================================
Our server RAM is 128 gb.... as per the note 1/2 of the physical RAM we can assign for SHMMAX parameter... (apprx 60gb)
How can i understood this answer for my configuration......
Please advice...
Thanks,

Max SGA size in 32bit OS

Hi,
I have a EBS Production Instance (12.1.1) in a 32-bit OS (RHEL4.0).
RAM: 16GB, SWAP: 8GB
Our sga size is 1.7GB
Is there any way to increase our SGA size.
Please advice.
Thanks in advance.

You can use BIG PAGES
For more info you can read the below docs:
http://www.oracle-base.com/articles/linux/LargeSGAOnLinux.php
32-bit Architecture and the hugemem Kernel
The RHEL 3/4 smp kernel can be used on systems with up to 16 GB of RAM. The hugemem kernel is required in order to use all the memory on systems that have more than 16GB of RAM up to 64GB. However, I recommend the hugemem kernel even on systems that have 8GB of RAM or more due to the potential issue of "low memory" starvation (see next section) that can happen on database systems with 8 GB of RAM. The stability you get with the hugemem kernel on larger systems outperforms the performance overhead of address space switching.
With x86 architecture the first 16MB-896MB of physical memory is known as "low memory" (ZONE_NORMAL) which is permanently mapped into kernel space. Many kernel resources must live in the low memory zone. In fact, many kernel operations can only take place in this zone. This means that the low memory area is the most performance critical zone. For example, if you run many resources intensive applications/programs and/or use large physical memory, then "low memory" can become low since more kernel structures must be allocated in this area. Low memory starvation happens when LowFree in /proc/meminfo becomes very low accompanied by a sudden spike in paging activity. To free up memory in the low memory zone, the kernel bounces buffers aggressively between low memory and high memory which becomes noticeable as paging (don't confuse it with paging to the swap partition). If the kernel is unable to free up enough memory in the low memory zone, then the kernel can hang the system.
Paging activity can be monitored using the vmstat command or using the sar command (option '-B') which comes with the sysstat RPM. Since Linux tries to utilize the whole low memory zone, a low LowFree in /proc/meminfo does not necessarily mean that the system is out of low memory. However, when the system shows increased paging activity when LowFree gets below 50MB, then the hugemem kernel should be installed. The stability you gain from using the hugemem kernel makes up for any performance impact resulting from the 4GB-4GB kernel/user memory split in this kernel (a classic 32-bit x86 system splits the available 4 GB address space into 3 GB virtual memory space for user processes and a 1 GB space for the kernel). To see some allocations in the low memory zone, refer to /proc/meminfo and slabtop(1) for more information. Note that Huge Pages would free up memory in the low memory zone since the system has less bookkeeping to do for that part of virtual memory, see Large Memory Optimization (Big Pages, Huge Pages).
If you install the RHEL 3/4 hugemem kernel ensure that any proprietary drivers you are using (e.g. proprietary multipath drivers) are certified with the hugemem kernel.
In RHEL 2.1, the smp kernel is capable of handling up to 4GB of RAM. The kernel-enterprise kernel should be used for systems with more than 4GB of RAM up to 16GB.

Sga size limits

Hi all,
Is there a metalink note or oracle list of the SGA size limits on the different platforms and 32/64bit?

Not sure that there is such documents on My Oracle Support. However TECH: Unix Semaphores and Shared Memory Explained (Doc ID 15566.1) explains how Oracle is using Unix/Linux shared memory segments.
Generally speaking I would say that maximum sga size is not an Oracle limit but an OS limit: on Unix it depends on SHMxxx kernel parameters and on Windows I don't know as Oracle architecture is quite different from Unix (a single but multithreaded process using "normal" memory).

Installing Oracle 8.1.7 on Linux RedHat 7.1

I am trying to install Oracle 8.1.7 on a Linux RedHat 7.1 machine with P4 1.7GHz. I 've tryed all the papers I found on the net for setting the user accounts and groups, linking with the old gcc libraries, etc. The problem is that after starting the OUI and when a window pops-up that spans the products list available, the whole operation finishes too quicly without reaching the 100%. At the next screen when I am trying to give the Instalation Unix group - should be oinstall/dba - I press next and get the message "Unable to setup Inventory. You may not have proper permisions". The machine has 256MBs Ram and 520MB Swap file on a 20GB HDD.Has anyone else seen this before? I couldn't find anything on the net. Can anyone help me? Thanks in advance...

Hi,
In the user where you are trying to install Oracle, give the following command at the prompt.
$ umask
The result should be "022". If it is not, connect as root and change the umask-settings of the user.
$ umask 022 <user-name>
and connect as the user, where you are trying to install and run the Installer.
Hope this will work,
Murali.

Unable to install Oracle 9.0.1 on Linux RedHat

Hi,
I am unable to install Oracle 9.0.1 on Linux RedHat, tried many times. While installing i get following errors-
"Error in invoking target install of makefile
/usr/oracle/9.0.1/plsql/lib/ins-plsql.mk"
"error in invoking target ioracle of makefile
/usr/oracle/9.0.1/rdbms/lib/ins-rdbms.mk"
"Error loading native library : libnjni.so"
Installation halts while configuring Net Confugration Assistant....
Any workaround ???
Thanks in advance.

There are many versions of RedHat. Your post indicates you are using one of them, but your post really does not give a hint as to which one. Funny thing is - different versions have different install requirements.
I really don't understand why operating system version is such a big secret. Especially since it is logically so critical to installation issue. Even when installing on Windows, the first questions is 'which Windows'.
You have, of course, followed the suggestions at http://www.puschitz.com and noted the errors and workarounds, have you not.
Especially about things like packages and versions.

Can OAS9i and Portal be installed on Linux RedHat(kernel 2.2.19) platform?

Hi,
My question is the same as the subject written.
Can OAS9i and Portal be installed on Linux RedHat(kernel 2.2.19) platform? Basically, first, I can't find the OAS9i "*.cp" image files for RedHat Kernel 2.2.16 or later use, second, what I can download from OTN site is V1.0.2.2.1 which is for Linux RedHat Kernel 2.4.3-12 or later use. And I downloaded all the files which OAS9i version is V1.0.2.2.1, and failed to install on my platform. So I want to know is there anybody installing OAS9i and Portal successfully on RedHat 6.2(Kernel 2.2.19, glibc 2.1.3)? Or can share on other RedHat version had any successful installation processes or suggestion. Thanks in advance.
Regards!
Frank

9iAS 1.0.2.x is only supported on Redhat 7.0 and Suse 7.2
