Kernal parameter SEMMSL & SEMMNS
Hi
We have 6 instances in a HP-UX box (B.11.11) , when i'm starting instances one by one, the last instance got failed to open, error in the alert reported is pasted below.
ksedmp: internal or fatal error
ORA-27154: post/wait create failed
ORA-27300: OS system dependent operation:semget failed with status: 28
ORA-27301: OS failure message: No space left on device
ORA-27302: failure occurred at: sskgpsemsper
After going thru the serveral investigations i found the SEMMNS or SEMMSL kernal parameter value needs to be changed, Can anyone please come up with good suggestions to change the kernal parameter and its restriction or any associated kernal parameters also changed or is any memory or the hardware needs to be checked on this.
Can any good experts help me would be appreciated.
Thanks
Venkat
I don't think it is going to be as easy as you hope.
The various parameters have interoperative affects on each other.
Another words, when you change one parameter, it affects another.
Anyway, on one of our HP-UX 11.11 boxes, with 12 Gb RAM and running 13 databases (v.9 and v.10), these are the memory settings in my system file.
semmni 5120
semmns 10240
semmnu 4092
shmmax 1573741824
shmmni 512
There are some awesome pages on the HP site dealing with kernel parameters. You can drill down about every kernel parameter and read everything you ever wanted to know about them all. I used to have it bookmarked, but unfortunately I've lost the bookmark.
You can go to the following HP web page, and this might be a good start to search for more information about HP-UX kernel parameters (or just google it).

hi,
i want to know why do we need to set kernal parameter before installing and creating database? can anyone explain this clearly..........
WIth Regards
Boohi,
Thank you yingkuan.where to set this Sga_max_size? do we need to set this in initialization parameter? how to view wat is the maximum sga_max_size?
is it possible to change the sga_max_size after database is created?
With Regards

Size of Kernel parameter and SGA
Hi,
Can you please suggest me the ideal size of kernel parameters and SGA?
Currently, I have installed 2GB RAM on my machine using Oracle 10.1 database version on Fedora Linux platform. The parameters are currently set as below:
kernel.shmall = 2097152 (2MB)
kernel.shmmax = 2147483648 (2048 MB)
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
I will appreciate if you can give me an idea about the proper size of SGA including SHARED_POOL_SIZE,LARGE_POOL_SIZE AND JAVA_POOL_SIZE.
Thanks in advance.
JayeshOracle's install docs indicate practical minimums. The specific section for Linux x86 is at
http://download-west.oracle.com/docs/cd/B19306_01/install.102/b15660/pre_install.htm#sthref264
The proper size of the pools is always dependent on the workload. It takes experience, understanding of the application and monitoring to size these properly - the realm of the DBA.
However, by setting the SGA_TARGET to some value (less than equal to SGA_MAX_SIZE) and setting these three parameters to '0', the system will use an effective compromise that dynamically changes based on workload.
My suggestion is that the SGA_TARGET and the PGA_AGGREGATE_TARGET be set to ensure the system does not start swapping - when considering all the other normal memory requirements on the system. -

2 (a) Using any text editor, create or edit the /etc/sysctl.conf file and add or edit lines similar to the following:
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 256 32000 100 142
fs.file-max = 131072
net.ipv4.ip_local_port_range = 10000 65000
kernel.msgmni = 2878
kernel.msgmax = 8192
kernel.msgmnb = 65535
I do not have sysctl.conf file under /etc.
I have changed some required values from
/proc/sys/kernel/msgmnb -- enter 65535, it was lower value b4
/proc/sys/kernel/msgmni -- enter 2878, it was lower value b4
/proc/sys/net/ipv4/ip_local_port_range --- enter 10000 65000 ,I added only 10000, it was 1000 b4.
Is it ok to change like that?
where is the sysctl.conf file?

Hello!
I have a oracle 9i instaled in Debian Linux.
When I try to create a new database (general purpose), with dbca i get the following error:
failure occurred at: skgpwreset1
ORA-27303: additional information: invalid shared ctx
ORA-27146: post/wait initialization failed
ORA-27300: OS system dependent operation:semget failed with status: 28
ORA-27301: OS failure message: No space left on device
ORA-27302: failure occurred at: sskgpsemsper
What could that be?
Thanks in advance..As Joel P�rez sugested.. check for kernal parameter.. u may to set respective kernal parameter properly..
Ex:
Some of the Kernal parameters are
Your parameters seems exceeding the minimum requirements Which are SEMMNI 100 SEMMNS 256 SEMMNS
parameter should be set to the Sum of the PROCESSES parameter for each Oracle database
(SEMMSL SHMMAX SHMMIN SHMMNI SHMSEG )

Ther is compatibility problem that happend with broken binaries
errno shouldn't show up with binary or library compiled against glibc 2.1+
You can use LD_ASSUME_KERNEL=2.4.1 (or 2.2.5) in the broken apps env
to work around this.

RH9 isn't certified for Oracle9i !!!
Note:201370.1
LINUX: Quick Start Guide - 9.2.0 RDBMS Installation
Quick Start Guide Oracle9i Release 2 (9.2.0) RDBMS Installation Linux Operating System PURPOSE ======= This document is designed to be a quick reference that can be used when installing Oracle 9.2.0 on the Linux platform. It is NOT designed to take the place of the Installation Guide. It is recommended that users READ the installation guide. Instructions to locate that document are contained in Appendix A. A familiarity with the Linux Operating System is assumed. If Installation guide information is needed, please see the Appendix A at the bottom of this document for additional resources. Each step should be done in the order that it is listed. These steps are the bare minimum that is necessary for a typical install of the Oracle9i RDBMS. Verification of Version Certification: ====================================== Currently, Oracle 9.2.0 is certified ONLY on the following Intel Based Server Linux distributions: - Red Hat Advanced Server 2.1 - Suse SLES7, SLES8 - United Linux 1.0 For the latest certification and other related information, use the "Certify & Availability" link in Metalink. Installations on distributions and versions not listed in the Certify link is not supported. Pre-requisite Requirements for System Administrator: ==================================================== The following steps are required to verify your operating system meets minimum requirements for installation, and should be performed by the root user. For assistance with system administration issues, please contact your system administrator or operating system vendor. Use these steps to manually check the operating system requirements before attempting to install Oracle RDBMS software, or you may choose to use the convenient "Unix InstallPrep script" which automates these checks for you. For more information about the script, including download information, please review the following article: Note:189256.1 UNIX: Script to Verify Installation Requirements for Oracle 9.x version of RDBMS Users must have /bin/utils installed for the operating system. This is part of the developers option on RedHat Advanced Server 2.1. The Following Steps Need to be Performed by the Root User: 1. Configure System Resources: Ensure that the system has at least the following resources: ? 400 MB in /tmp * ? 512 MB of Physical Memory (RAM) ? Three times the amount of Physical Memory for Swap space (unless the system exceeds 1 GB of Physical Memory, where two times the amount of Physical Memory for Swap space is sufficient) * You may also redirect /tmp by setting the TEMP environment variable. This is only recommended in rare circumstances where /tmp cannot be expanded to meet free space requirements. 2. Create a Software Owner and Group: Create a Unix user and group that will own the Oracle software. (Typically user = oracle, group = dba) You may use a GUI tool for this if your distirbution provides one, or the 'useradd' and 'groupadd' command line utilities. Please make sure the user and group you use are defined in the local /etc/passwd and /etc/group files rather than resolved via a network service such as NIS. 3. Create a Software Mount Point and DataFile Mount Points: Create a mount point for the Oracle software installation (at least 2.5 GB, typically /u01) Create a second, third and fourth mount point for the database files, control files, and log files to be created (typically /u02, /u03, /u04). ? The oracle user should own these mount points and all of the directories below the mount point. 4. Test the Permissions: Ensure that the oracle user can write to the new mount points ? As a test, change directories to each of the new mount point directories as the oracle user and create a file or directory. Example: % touch /u01/test 5. Configure Kernel Resources: The following kernel parameters related to shared memory and semaphores will require tuning: SHMMAX = 2147483648 SHMMIN = 1 SHMMNI = 100 SEMMNS = 1000 SEMMSL = 250 SEMMNI = 100 SEMOPM = 100 6.On Linux kernel parameters can be set dynamically or can be written in a shell script to be set at boot time. Kernel parameters should be set as the root user. They are set as follows 1. cd /proc/sys/kernel 2. Modify the parameter values by using the following command syntax: a. # echo 100 32000 100 100 > sem This sets SEMMSL, SEMMNS, SEMOPM, SEMMNI b. # echo 2147483648 > shmmax c. # echo 1 > shmmin d. # echo 100 > shmmni ================================================================================ These changes are NOT persistent and must be re-set after each re-boot. On RedHat Advanced Server 2.1, these parameters can be entered into the file /etc/sysctl.conf. This parameters in this file are set each time the system is booted. Example: $ more /etc/sysctl.conf # Disables packet forwarding net.ipv4.ip_forward = 0 # Enables source route verification net.ipv4.conf.default.rp_filter = 1 # Disables the magic-sysrq key kernel.sysrq = 0 kernel.shmmax=256000000 kernel.shmmin=1 kernel.shmmni=100 kernel.sem= 250 32000 32 128 7. Mount CD-ROM: Depending on your Linux distribution the cdrom device is typically either "/cdrom" or "/mnt/cdrom". Please substitute the appropriate value when "<cdrom>" appears in the examples. # mount <cdrom> Installs can be done from either the CD or by copying the contents of each CD?s to a stage area on the local disk (/stage/Disk1, /stage/Disk2, /stage/DiskN) 8.This is required to run as root: /tmp/orainstRoot.sh First question of oracle installation. If no other versions of Oracle 8i or 9i have been installed before. You will be ask to run /tmp/orainstRoot.sh to create the oraInventory location pointer. Usually found in /etc on Linux Files that are located in /etc are /etc/oratab and /etc/oraInst.loc Installation Steps for the Oracle User ======================================= The Following Steps need to be performed by the Oracle User: This can be done from either a Telnet or an SSH connection. It is NOT recommended to perform installations from a su ? oracle connection. 1. Set Environment Variables Environment variables should be set in the login script for the oracle user. If the oracle user's default shell is the C-shell (/usr/bin/csh), then the login script will be named ".login". If the oracle user's default shell is the Bourne-shell (/usr/bin/bsh) or the Korn-shell (/usr/bin/sh or /usr/bin/ksh), then the login script will be named ".profile". In either case, the login script will be located in the oracle user's home directory ($HOME). The examples below assume that your software mount point is /u01. Parameter Value ----------- ------ ORACLE_HOME /u01/app/oracle/product/9.2.0 ORACLE_BASE /u01/app/oracle PATH /u01/app/oracle/product/9.2.0/bin: /usr/ccs/bin:/usr/bin/X11/:/usr/local/bin and any other items you require in your PATH ORA_NLS33 $ORACLE_HOME/ocommon/nls/admin/data ORACLE_SID Set this to what you will call your database instance. (4 - 8 characters in length) If you are not on the console, you may need to set the following DISPLAY <ip-address>:0.0 (review Note:153960.1 for detailed information) ENSURE THAT CLASS_PATH IS NOT SET IN THE ENVIRONMENT 2. Set the umask: Set the oracle user's umask to "022" in you ".profile" or ".login" file. Example: umask 022 3.

MAX. NO. OF PROCESSES exceeded
We have RAC setup running on SunSolaris SPARC (64-bit) server, with 32G RAM on each instance. Current setting for processes
parameter is 5000, but unable to increase it.
It raises an error ORA-00020: maximum number of processes (string) exceeded.
Kernel parameter for given scenario is:
set semsys:seminfo_semmni=100
set semsys:seminfo_semmns=1024
set semsys:seminfo_semmsl=256
set semsys:seminfo_semvmx=32767
set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmseg=10
Referring to other forums & docs, it says maximum no. of semaphores should be less than or equal to (SEMMSL*SEMMNI) or SEMMNS, whatever is smaller.
According to this calculation, It should not work for 5000 even, taking SEMMNS=1024. What is the workaround I can follow??
It's urgent, on production system!!!!
Regards,
user1012Hi,
Thanks for your interest.
Here is the scenario:
We're using a J2EE based application on Radius. Thousands of client requests striking in seconds. So it's a very huge RAC configuration with 32G memory & 2 nodes in cluster. As per our RDA analysis, it shows dead processes may be one of the reasons it goes beyond the maximum processes.
Now my question is,
1. What are possible values of SGA & PGA allocation based on this OLTP architecture?
2. Are kernel parameters well set?
4. How to remove dead processes from memory? -
Problem in Database Configuration Assistant
I did install successfully oracle9i(9.2.0) database program install Step
but "Configuration Tools" Step is not work
- Copying databases Files - oK.
- Initializing database -ok.
- creating and starting Oracle instance - still progress
and it could not progress next step.
How ca i solve this problem?you can check Document ID Doc ID: 201370.1 in the metalink
Configure Kernel Resources: The following kernel parameters related to shared memory and semaphores will require tuning:
SHMMAX = 2147483648
SHMMIN = 1
SHMMNI = 100
SEMMNS = 1000
SEMMSL = 250
SEMMNI = 100
SEMOPM = 100
On Linux kernel parameters can be set dynamically or can be written in a shell script to be set at boot time. Kernel parameters should be set as the root user. They are set as follows
1. cd /proc/sys/kernel
2. Modify the parameter values by using the following command syntax:
a. # echo 100 32000 100 100 > sem
This sets SEMMSL, SEMMNS, SEMOPM, SEMMNI b.
# echo 2147483648 > shmmax c.
# echo 1 > shmmin d.
# echo 100 > shmmni ==========================================================
These changes are NOT persistent and must be re-set after each re-boot.
On RedHat Advanced Server 2.1, these parameters can be entered into the file /etc/sysctl.conf.
This parameters in this file are set each time the system is booted.
Example: $ more /etc/sysctl.conf # Disables packet forwarding net.ipv4.ip_forward = 0 # Enables source route verification net.ipv4.conf.default.rp_filter = 1 # Disables the magic-sysrq key
kernel.sysrq = 0
kernel.shmmax=256000000
kernel.shmmin=1
kernel.shmmni=100
kernel.sem= 250 32000 32 128 -

please, notePROCESSES is 270 (not the default)
and i'm trying to set the following parameters on the new instance:

log_buffer 655.360

this is my /etc/system:

but as the "create database" starts, i get the ORA-01034 ORACLE NOT AVAILABLE error.
i found this info in the crdb1.log:
Connected.
ORA-00101: invalid specification for system parameter MTS_DISPATCHERS
CREATE DATABASE "ADS"
ORA-01034: ORACLE not available
Disconnected.
but why do i have the MTS_DISPATCHERS paramenter if i set dedicated server mode? i guess i don't need MultiThreading...
anyway, are the semmsl, semmni, semmns parameters correctly configured? i rememeber i had a similar error and these parameters were to set correctly to make it work, but this time i can't find out the point!!!
please, it's very urgent...
thankx a lot!
mattei'm installing a new instance, so i don't need neither to set ORACLE_SID, nor to connect to db. i mean... i give my oracle sid in the GUI of the dbassist.
then it's supposed to set it and connect to the instance by its own. the point is that when it tryes the connect internal, it fails.
i bet the trouble is in the /etc/system parameters, but i don't know exactly where.... -

Edited by: Lain on 13-gen-2011 20.06Make sure you have ssh configured properly on both nodes.
Do you have the Oracle Clusterware Installation 11g Release (whatever your platform is)?
Read this section 2.12.3 Enabling SSH User Equivalency on Cluster Member Nodes
Try this on rac1.
ssh rac2 date
Try this on rac2.
ssh rac1 date
If these don't return the date of the other host you haven't configured SSH properly. -
RedHat 6.2 Intel - Oracle8i (8.1.5)
RedHat Linux 6.2 Server Install (Intel) 256Mb RAM, Oracle8i (8.1.5) for Linux Intel.
Please help, I am thoroughly confused, I just want the install to go well and am sure this is a critical task. I am not a c guy so don't quite follow the "Configure the Linux Kernel for Oracle8i" steps. More importantly I DO NOT know how to re-build the kernel if I did successfully make any changes.
Below are is the excerpt from the Install Guide for Oracle Database 8i (8.1.5) CD Pack v5 for Linux Intel - "Configure the Linux Kernel for Oracle8i". Directly below is a copy of my shmparam.h and sem.h files. I have no idea on how to configure. Can someone maybe paste copies of their files, or show me how to make my changes if necessary?
Thanks A MILLION In Advance For All That Can Help! Seriously!

Configure the Linux Kernel for Oracle8i
Configure the Linux kernel Interprocess Communication (IPC) parameters to accommodate the Shared Global Area (SGA) structure
of the Oracle8i Server. You will not be able to start up the database if the system does not have adequate shared memory to
accommodate the SGA.
1. Use the ipcs command to obtain a list of the current shared memory and semaphore segments of the system. and their
identification number and owner.
2. Set the following kernel parameters in:
/usr/src/linux/include/asm/shmparam.h and
/usr/src/linux/include/linux/sem.h
- maximum size of the shared memory segment (SHMMAX)
- minimum size of the shared memory segment (SHMMIN)
- maximum number of shared memory identifiers in the system (SHMMNI)
- maximum number of shared memeory segments a user process can attach (SHMSEG)
- maximum number of semaphore identifiers in the system (SEMMNI)
- maximum number of semaphores in a ser (SEMMSL)
- maximum number of semaphores in the system (SEMMNS)
- maximum number of operations per semop call (SEMOPM)
- semaphore maximum value (SEMVMX)
The total allowable shared memory is determined by the formula:
SHMMAX * SHMSEG
Table 2-1 shows the recommended settings. The recommended values are optimal for one instance and are based on the default
initsid.ora file. If you plan to install more than one instance, or to modify the initsid.ora file extensively, set these
parameters higher.
To set the kernel parameter for SEMMNS, use the formula in Table2-1. For example, consider a system that has three Oracle
instances with the PROCESSES parameter in their initsid.ora files set to the following values:
ORACLE_SID=A, PROCESSES=100
ORACLE_SID=B, PROCESSES=100
ORACLE_SID=C, PROCESSES=200
The value of SEMMNS is calculated as follows:
some formula i'm sure i don't have to worry about.
3. Rebuild the kernel if you have modified the kernel, shared memory, or semaphore parameters.Just in case anyone is having same problems, I discovered how to handle this:
linux kernels from major version 2.2 forward allow dynamic system settings at runtime. You can change the maximum size of shared memory, SHMMAX, for example by echoing the desired value to the appropriate parameter location in the running kernel. Edit the linux startup script file
/etc/rc.d/rc.local and add the following line:
echo 500001024 > /proc/sys/kernel/shmmax
this is an appropriate shared mem max for an SGA of 500,000,000 bytes.

bye the bye - 8.1.5 - desupported by Oracle, install >= 8.1.6 on RH6.2 goes smooth...

Any idea ?
Can't find anything good on metalink or when googling.
The only thing I found is a patch for linux on ibm system Z, which is not my case :(

Kernel Parameter Settings
Edit the /etc/sysctl.conf file and add or edit lines similar to the following:
kernel.shmall = 2097152
kernel.shmmax = 4294967295
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 256 32000 100 142

kernel.msgmax = 8192
kernel.msgmnb = 65535
net.ipv4.tcp_window_scaling = 0
net.ipv4.tcp_moderate_rcvbuf = 0
net.ipv4.tcp_keepalive_time = 600
net.ipv4.tcp_keepalive_intvl = 60
net.ipv4.tcp_keepalive_probes = 20
net.ipv4.tcp_retries1 = 25
By specifying the values in the /etc/sysctl.conf file, they persist when you restart the system.
Set Shell Limits for the oracle User
Add the following lines to /etc/security/limits.conf file:
* soft nproc 2047
* hard nproc 16384
* soft nofile 2048
* hard nofile 65536
Each line follows this format:
<Tab><Tab>soft<Tab>nofile<Tab><Tab>16384
Add the following line to the /etc/pam.d/login file, if it does not already exist:
session required /lib/security/pam_limits.so
Depending on the oracle user's default shell, make the following changes to the default shell start-up file:
Check your /etc/profile file -
ORA-01034: Oralce not available
Hi,
I install oracle 8.1.7 on solaris 7...
lsnrctl & svrmgrl works good but i meet problem ...
SVRMGR> == any sql ===
---> ORA-01034: ORACLE not available
also at the creating database period, always shows oracle not available error...
How can I solve these problems?
Best RegardsHi William,
So what would you suggest those two parameters be set to?
P.S. I am having the same problem, except with Oracle8i 8.1.7 on Solaris.
Thanks,
Rupal Ok, SEMMSL & SEMMNS are both a function of the largest processes parameter in the init.ora
for the databases on the same system. The starter DB has 150 processes. The oracle formula
says 160 & 310 respectively. I believe the key is SEMMNS because it determines the number
of semaphores in the system.
Try 200 & 400 in /etc/system and reboot. That is probably a little overkill, but it should work.
Besides, when you add DBs you will need to adjust/tune those parameters anyway.
