Kernel parameters

Hello

I have an instance R12 all services on the single node and the ram size is / 3GB and the kernel.shmall kernel.shmmax kernel parameters are not defined as by the notes 402310.1 , they are more than the recommended value, for this reason, I get a lot of memory related issues such as its unable to PGA allocated for new connections. I wanted to know if these settings are true culprit of connectivity issues.

Kind regards
Satya.

Hi Satya,

Good to hear about this problem is resolved.

You are welcome!

Kind regards

Linux kernel parameters and Oracle memory allocations.
I'm currently creating an Oracle 11 G R2 in database, on a Linux (SLES 11) OS. The software OS and DB are the two 64-bit.
I wondered about the optimal method of memory allocation shared, such that I can get the automatic memory management to recognize 12G of memory (which allows 4 g for the operating system and other pieces).

I put the kernel parameters are:
SHMMAX: 8589934592 (the recommended physical memory/2).
SHMALL: 3145728 (giving a total of 12 GB of shared memory allocation that the page size is 4096).

The way I read the documentation, it must free up enough shared memory to allow the specification of a memory_max_target and memory_target "11 g". I'm getting 11G to ensure that I am not ruin by a few bytes (if it all works, I will develop to 12G).
However, whenever I try a startup, I get the ' ORA-00845: not supported on this system MEMORY_TARGET' error.
It disappears if I create a great shmfs block using a mount command, but I was under the impression you had is no longer to do with 64-bit and Oracle 11 G system.

Could someone clarify a little bit about what I'm doing wrong and where I should be looking for the answer?

See you soon,.

Yum is certainly the way to go because it solves software dependencies, this isn't the RPM. The problem with RHEL is that it does not provide a public yum repository and you will pay a subscription. CentOS and Oracle Linux are not.

Kernel parameter Impact the performance of Timesten
Hello

Can you please guide me on the impact of certain parameters of the kernel/hardware on Timesten performance:

kernel.shmmax
kernel.shmall
kernel.msgmni
kernel.shmmni

I have two servers with the same Timesten DSN configuration. A particular process takes 15 ms on a single server (Server A) and 5 (Server B) ms on the other hand. Timesten versions and linux on both are similar. Memory is the same (32 GB). The DSN settings are exactly the same as well.

Hi Kiki,

These kernel parameters affect the performance. They will simply affect how much shared memory, messages and semaphores are configured in the kernel. This could affect whether a particular TimesTen data store can be loaded into memory or not, but if it charges so that they have no real effect on the performance.

The difference in performance is due to this:

model name: Intel(r) Xeon E7540 CPU @ * 2.00GHz*
step by step: 6
CPU MHz: * 1064.000*
cache size: 18432 KB

in relation to this:

walk: 2
CPU MHz: * 2400.000*
cache size: 12288 KB
CPU cores: 4

The second machine has a significantly faster processor...

Change the kernel settings after 10g Software Installation
Hello world

I need to install Oracle 10 g 2 in a box of HP - UX Itanium for an upgrade of Database 9i and 10g and some have recommended prerequisites of the kernel are not defined as requested for the installation program. Kernell settings have been changed in order to fulfill the preconditions but the can´t server be rebooted now because it is a production environment, it will be restartedb in two weeks, but I want to start right now with the installation software.

My question is: safetly can I install the software, and after restarting the server, perform the upgrade of my database?

The kernel parameters that failed were:

Hi Alvaro;

I belive that you can go to to ignore this message on your installation. But after installation you need to restart your server coz if you keep working like this probably will hit you on your db errors

10g Universal Installer kernel errors when installing on Solaris 5.10
Hi all

I tried to install Oracle 10 g on a Solaris 5.10 (32-bit), in accordance with the official Oracle Documentation for a few days now. It seems that the Universal Installer fails it's pre-installation steps and throws error in the following kernel parameters:

Audit of 4294967295 = shmsys:shminfo_shmmax; no entry found. Failure of < < < <
Verification of the shmsys:shminfo_shmmni = 100; no entry found. Failure of < < < <
Verification of the semsys:seminfo_semmni = 100; no entry found. Failure of < < < <
Verification of the semsys:seminfo_semmsl = 256; no entry found. Failure of < < < <
Full version. The result of this review is: failure of < < < <

I followed the Oracle Documentation that says to change the kernel settings using control resources center. To do this, I already have a project 'oracle' user 'oracle' was awarded to:

Oracle of $ id - ap
uid = 100 (Oracle) gid = 100 (oinstall) groups = 100 (oinstall), 101 (dba) projid = 100 (oracle)

----------------------------------------------------------------------------------------------

Here are snapshots of the prctl command on the current state of the kernel parameters:

For the verification of shmsys:shminfo_shmmax = 4294967295; no entry found. Failure of < < < <

$ prctl - n Project.Max - shm-memory - i project oracle
project: 100: oracle
NAME PRIVILEGE VALUE FLAG ACTION BENEFICIARY
Project.Max - shm-memory
the privilege 254MB - deny-
system 16.0EB max deny-

The recommended Oracle value is 4 GB - I expect check Universal Installer fail to do this, so I change the setting using the installation of control of resources by logging in as root in a new terminal and maintain an oracle session active.

# prctl - n v Project.Max - shm-memory - 4 GB - r-i oracle project

I see that the parameter has been set correctly when I do:

$ prctl - n Project.Max - shm-memory - i project oracle
project: 100: oracle
NAME PRIVILEGE VALUE FLAG ACTION BENEFICIARY
Project.Max - shm-memory
4.00 GB privilege - deny-
system 16.0EB max deny-

----------------------------------------------------------------------------------------------

For the verification of semsys:seminfo_semmni = 100; no entry found. Failure of < < < <

$ prctl - n Project.Max - sem - IDS - i project oracle
project: 100: oracle
NAME PRIVILEGE VALUE FLAG ACTION BENEFICIARY
Project.Max - sem - IDS
privileged 128 - deny -.
system of 16.8 M max deny-

The recommended Oracle value is 100 - I don't expect this setting Universal Installer verification failed

----------------------------------------------------------------------------------------------

For the verification of shmsys:shminfo_shmmni = 100; no entry found. Failure of < < < <

$ prctl - n Project.Max - shm - IDS - i project oracle
project: 100: oracle
NAME PRIVILEGE VALUE FLAG ACTION BENEFICIARY
Project.Max - shm - IDS
privileged 128 - deny -.
system of 16.8 M max deny-

The recommended Oracle value is 100 - I don't expect this setting Universal Installer verification failed

----------------------------------------------------------------------------------------------

Also when I try to run the command:
$ prctl - n Project.Max - sem-nsems - i project oracle

I get:
prctl: unable to get control of the resources for Project.Max - sem-nsems: invalid argument

Oracle recommends that I have to set a value of 256.

After the implementation of all this, I still get the following errors of the Universal Installer:

Audit of 4294967295 = shmsys:shminfo_shmmax; no entry found. Failure of < < < <
Verification of the shmsys:shminfo_shmmni = 100; no entry found. Failure of < < < <
Verification of the semsys:seminfo_semmni = 100; no entry found. Failure of < < < <
Verification of the semsys:seminfo_semmsl = 256; no entry found. Failure of < < < <
Full version. The result of this review is: failure of < < < <

Now, when I change the kernel settings by editing the file/etc/System without even a reboot that I can see all my nucleus Universal Installer checks as adopted.

Not sure if I'm missing a crucial step when configuring the kernel parameter using the installation of control of resources?

~ Somjit
This is a bug in YES.
YES looking for/etc/System to check the setting of the parameters of the kernel, but this file is not used (by default) in Solaris 10
He must check the adjustment of the parameters of the kernel using the prctl.

MetaLink Note 363436.1

workaround is to
. / runInstaller - ignoreSysPrereqs
or that you already have, edit/etc/System as well.

Since you did the recovery I assumeyou already tried to the unit powering down and back up.

This is a weird problem I havn't seen before, but sometimes the sensors get currupt and need a full reimage to return to normal.

I would like to download the most recent image 4215 and TFTP in your sensor in ROMMON.

ORA-01034: ORACLE not available ORA-27101: Kingdom is no Linux-x86_64 shared memory error: 2: no such file or directory process ID: ID of Session 0: 0 serial number: 0

Hello
In our society, we have oracle server on Suse Linux with two instances TETA and TETA201.
One day on a server broke down, because there is no free space due growing files 'archivelog.
After that I manually deleted several older archivelog files, but after the reboot, the server error occurs when connecting to the database:
"ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux x86_64 error: 2: no such file or directory
Process ID: 0
"Session ID: serial number 0: 0"
$ ORACLE_SID is set to TETA, if export it to TETA201 connection works correctly
Oracle service startup there is no errors but only one instance is running TETA201 works correctly

Unable to increase the SGA in linux x 86

Hi all
Oracle 9iR2
Linux x 86
I'm unable to increase from 1.8 to 3.5 GB SGA am getting error below. Please suggest me.
ORA-27123: unable to attach to the shared memory segment
Linux error: 22: invalid argument
Additional information: 1
Additional information: 1966088
/ proc/sys/kernel/shmmax: / 3 GB, I tried to rise but not luck...
Thank you
Sam.

Thank you all...

its 32-bit, this means no chance to increase the SGA by increasing the kernel parameters? is this correct?

Oracle on Linux 32-bit can be used up to an LMS (if I remember correctly) 16GB. You start the PAE kernel, and then configure your cache with use_indirect_data_buffers and db_block_buffers. Your pool will always be limited (even once, I forgot the details) to something less than 2 GB.

Takes back me a few years.

kernel.shmmax is 512 MB, but I think that my machine has 16 GB.
user@host:~$ cat/proc/meminfo | grep MemTotal
MemTotal: 16326920 kB
512 * 1024 * 1024 = 536870912 (verified with calculator just in case)
16326920 k == (16326920 * 1024), i.e. the value in bytes.
If that's the problem, I do not understand why this is important. With 16 GB, there should be plenty of space. Also maybe this isn't the only place where there is a specification for memory.

I figured this out on my own.

move /etc/sysctl.d/60-oracle.conf to ~ / and restarted to make the correct available then I did:

user@host:~$ grep - n ".» ' * ' / proc/sys/kernel/shmm *.

/ proc/sys/kernel / shmmax:1:33554432

/ proc/sys/kernel / shmmni:1:4096

OK, so appearing kernel.shmmax = 33554432 60 - oracle.conf and move back to /etc/sysctl.d/
Then reload:

starting the service sudo procps

OK, take - another execution during the configuration:

configure sudo /etc/init.d/oracle-xe

Leading to:

.. all the things we saw before followed...
