Changing ulimit for Oracle user

Hi expert,
I'm using AIX 5.3 TL 9 with Oracle 11g R2.
Does changing rss in ulimit for oracle user operating system require restart oracle instance ?
Need your advice.
Thanks,
Yusata.

ulimit values are read only once when the process is started.
When we are at it: what did 'man ulimit' tell, and why are you asking Unix questions in an Oracle forum?
Please stop cluttering up this forum with off-topic questions, without them it is enough of a mess already.

Ulimit for oracle user

OL 5.6 x86-64, running under VirtualBox
Background
I've built quite a few sandbox servers under Vbox, and always loaded the necessary packages with a 'yum install oracle-validated'. Also using a standard template .bash_profile, that includes this information regarding ulimit
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
    ulimit -p 16384
    ulimit -n 65536
else
    ulimit -u 16384 -n 65536
fi
fi
#no problems with any of the above
Issue
Now I've decided to build a box that mimics one of my production servers as closely as I can get it. To that end, instead of installing 'oracle-validated', I went to the production box and captured the output of 'rpm -qa', then edited that output turn each line into a 'yum -y install ...' command, and executed the result on the vm.
Now, when I connect as 'oracle' I get
-bash: ulimit: max user processes: cannot modify limit: Operation not permittedI'm not sure of what I could have done differently this time to result in this behavior.

The ulimit facility provides hard and soft limits. With the ulimit command, you can change your soft limits, up to the maximum set by the hard limits.
To see current hard and soft limits:
ulimit -Ha
ulimit -Sa
Account specific limits are set in /etc/security/limits.conf. You will most likely need to increase the limits of the Oracle user. In particular add the following:
oracle soft nofile 131072
oracle hard nofile 131072
oracle soft nproc 131072
oracle hard nproc 131072
oracle soft core unlimited
oracle hard core unlimited
oracle soft memlock 50000000
oracle hard memlock 50000000
The oracle-validated package does more than just triggering the installation of additional packages. It also sets various system kernel and oracle account parameters. For details:
# wget http://public-yum.oracle.com/repo/OracleLinux/OL5/latest/x86_64/oracle-validated-1.1.0-17.el5.x86_64.rpm
# rpm2cpio oracle-validated-1.1.0-17.el5.x86_64.rpm | cpio -idmv
Then analyze the files.

Change of UID for Oracle user - Impact

Many thanks for the response. We are not changing the UID but there are some errors in the script related to file permissions. So just wanted to know will it have any impact on the database if we change the UID.

Changing passwords of oracle users

Dear all
I wander is there any problem if changing password of oracle users SAPOWNER, system,sys . (I guess command for that is brconnect -u system/<password> -f chpass -o <sapowner> -p <password>
). What about sys and system. (I hope that after changing passwords the system will be functional)
Which user is used when "sqlplus / as sysdba"
thank you in advance

Hello Jan,
I wander is there any problem if changing password of oracle users SAPOWNER, system,sys
Well we already discussed the SAPOWNER here: http://forums.sdn.sap.com/message.jspa?messageID=10814500#10814500
If you change the password of SYSTEM or SYS there will be no problem at all. These users/password combination is not used in a SAP environment unless you explicitly specify the SYSTEM user and password in some BR*Tools calls like brconnect. If you just use the "/" default approach, the OS authentication mechanism (OSDBA) is used - so no issue there at all.
@Orkun:
This is not a user, but a role. So when you connect to the database by using "/as sysdba" you will be able to connect to the system by sysdba role not by a user.
If you use this apporach you are connected with the user SYS - so you are using a user for sure (and btw. you can only logon with SYS by using SYSDBA role). The only difference between "sqlplus / as sysdba" and "sqlplus SYS as sysdba" is, that you are using the specified OSDBA group with the first approach (so no password is required).

Change permission for Oracle inventory.

When I installed Oracle 10gR2, I have specified dba group for Oracle inventory as it was a primary group for Oracle user. Now I want to change the group to orainstall. Is it possible to do that now with out affecting Oracle software or residing databases and do I need to specify orainstall as primary group and dba as secondary group?
If anyone does have good doc or link for rebuilding orainventory, please send it across.
Appreciate your help!!!

But you can always use any other name for dba group -
like dba92, or dba99, or aaa, or even oinstall as the
dba group. Same thing with the "oinstall" as well,
Oracle binary DOES NOT recognize the character - just
the group ID, of "oinstall".
Correct me if I am wrong.
Thanks.Of course you can pickup whatever name you like, but you need to decide your group name before installation. After installation if you plan to change the 'dba' group name, you need to modify config.s file and recompile Oracle executables.

Good Morning Oracle Experts ;
Basicallly my major subject is Electrical and Electronics
I am very new to ORACLE/LINUX [ LEARNING ORACLE DBA ] Technology.
I have THREE questions .. Please help me to understand oracle concepts.
QUES 1 :

QUES 2 :
Please note : This url says   lot of env variables
http://www.idevelopment.info/data/Oracle/DBA_tips/Unix/UNIX_4.shtml
2 . In my case , Why following env variables *[LD_ LIBRARY_PATH , CLASS_PATH , PATH]* are missing ?
My pc showing only four env variables   $ env | grep -e ORA -e TNS

QUES 3 :
*[ LD_ LIBRARY_PATH , CLASS_PATH , PATH ]*
*Are they [ above mentioned env variables] necessary (or) not necessary for oracle DB ?*
When listing env variables , why   they are not displayed ? (anything wrong ) ?
As a beginner , I expect some clean technical information    to improve my knowledge ..
Thanks in advance ;

Password for Oracle user , sys , system , saprpd

Hi All ,
I just join a new company as sys admin . I tried to search password for Oracle user sys , system and saprd in my company password file . Those users password are not stored.
Am I supposed to know those oracle user password ? If yes , Can I find them in my Unix system or sap application ?
Please help !
Felix

It is not possible to determine the passwords if you don't know them. But perhaps note 562863 and the described default passwords are useful. Furthermore you can always change passwords if you have SYSDBA privilege using "alter user ... identified by ..." or "brconnect -f chpass".

Two things. First, I'm not exactly sure what password you are trying to
change. The LDAP server's password or a user's password in the LDAP
server. Second, could you please post a stack trace.

Hai,
This condition based execution requires - javascript coding.
In miscelleaneous tools bar, you have an option of SCRIPT_ITEM writer tool, drag the tool into your WAD layout, and select the properties , choose the editor option and paste your coding. that's it.
Alternate option :
in your web application design layout , you will fine XHTML coding editor , there you need to write coding and execute the same.
Hope this will help to you.

What is the password for 'oracle' user created during XE installation?

Hi,
What is the password for 'oracle' user automatically created when XE is installed?
I installed XE on Linux and it's created under 'oracle' user, but I don't know 'oracle' password. So, I cannot stop TNS listener.
During configuration, it prompted me to enter SYS and SYSADMIN password but it didn't ask me to enter 'oracle' user password.
Please let me know or point me to the document.
Thanks,
N

Hi Jari,
I tried your suggestion, but it didn't work unfortunately.
When I type (sudo su -oracle) as follows, it still prompts the password. When I hit Enter key w/o anything, it seems to proceed and the prompt shows up in the following line. So, I thought it was successful, but when I checked 'whoami', it's not logged in as 'oracle'.
So, I created the password for 'oracle' and logged in as 'oracle' using a new password. Then, I stopped TNS listener to uninstall XE.
It would be nice if it's documented in XE document somewhere... since it's created by XE installation, I assumed some kind of default password was used.
Thanks,
N

Where can I change desktop for anonymous user ?

Hello.
Where can I change desktop for anonymous user ? I'd like to change it in the same manner as sampleportal desktop (with amconsole) , but I did not found it in the amconsole.
If you know, please, tell.

The user "authlessanonymous" holds the information that people see if they are not signed on. It can be changed like any other user. It may have to be enabled under the Service Configuration tab -> portal desktop.

I am unable to change passwords for any users. The "change password" is grayed out.
