Setting Resource limits for Oracle user in 11gR2

HI Friends,
I am using Oracle Database 11g R2 on windows.
My Application connects to the database using a schema (user1). Some times the application user sessions makes the Database usage / CPU/ IO high and affecting the performance of the Database.
I would like to set some Limits on the Resource usage (Database and System resources) for those Application user schema (user1) to avoid the bottleneck on the Database and Server without affecting the usage of the Application on Transactions.
How can i achieve it?
Regards,
DB

Env settings for oracle user , when installing Oracle on linux

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 :
i am getting confused about “setting bash_profile” and it’s contents
I googled , it said to set env variables for oracle user. Ok .
Can anyone explain clearly what exactly happens when “ setting bash_profile ” ?
MY   BASH_PROFILE SETTINGS
My bash_profile having following contents :
+# Oracle Settings+
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1; export ORACLE_HOME
ORACLE_SID=TSH1; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
+#LD_ASSUME_KERNEL=2.4.1; export LD_ASSUME_KERNEL+
+if [ $USER = "oracle" ]; then+
+if [ $SHELL = "/bin/ksh" ]; then+
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
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
ORACLE_SID=TSH1
ORACLE_BASE=/u01/app/oracle
ORACLE_TERM=xterm
ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1
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 ;

Shell Limits for Oracle DB 10g under SLES 9

Hi.
We installed SLES 9 and want to install now Oracle DB 10g R2.
We are at configuring Linux for the installation process using this guide: http://www.oracle.com/technology/pub/articles/smiley_10gdb_install.html#shell
At the linked part (shell limits) is explained how to set the shell limits for the user oracle. And there are two parts, one for SLES9 and one for RHEL4.
But the files profile.local and csh.login.local are not existing! But the files from the RHEL4 section (profile and csh.login) exists.
Is this a failure in the guide? Are the two parts from RHEL4 and SLES9 switched?
Or it is right that we have to create these files by setting these shell limits??
Thanks for answering.

Hi.
I usually create these files on the Suse box. These files are never there on either x86, ia64 og x86(64).

Bingo.... I got it.
Thanks for your hint about the ./.profile. I was setting env variables in .cshrc file and my default shell for "oracle" user was sh.
Then I changed the default shell for oracle user to csh and viola..... it works.

$ id

$ setenv

How to set Internet limits to particular user by gpo ?

How to set Internet limits to particular user by gpo ?
Thanks & Regards, Amol . Amol Dhaygude

Hi,
>>How to set Internet limits to particular user by gpo ?
What Internet limits do you want to set for specific users? Group Policy user settings can be configured to apply to specific users, like via security filtering or GPP item-level targeting. The path for Internet Explorer policy settings under User Configuration
is: User Configuration\Policies\Administrative Templates\Windows Components\Internet Explorer.
You can also use GPP Internet Settings extension to manage IE settings and use GPP ILT to apply the settings to specific users. However, GPP settings can be edited by standard users after getting applied.
Regarding GPP Internet Settings extension, the following article can be referred to for more information.

Set Tolerance Limits for Price Variance when PO-based Purch.Requisition

We must garanty that Price from Purch.Requisition will be the same at PO.
IF some variance occur a error messag must be sent to user and PO could not be saved.
I found at customzing under SPRO > Materials Management > Purchasing > Purch.requisition > Set Tolerance Limits for Price Variance .
Reading the help of customizing it mean the system consists what we need..
I have created tolerance limit NB, and set limits for all checks as 0,01.
When I will activate messages as recommended on help no messages 601 and 602 have the text that guide us to correctly setting.
The help mention that after create tolerance limit we must set this tolerance by document type..but I didnt find this field at customzing
Does anyone can help me ?
See the help on customizing below
Set Tolerance Limits for Price Variance
In this step, you can define percentage-based and value-based (absolute) tolerance limits for price variances between purchase orders and purchase requisitions. Variance types are mapped out in the SAP system by tolerance keys.
You define the tolerance limits for each tolerance key and assign your tolerance key to the document types for purchase requisitions. The tolerance limit then applies for all documents of this document type.
When processing a purchase order, the system checks whether the unit price of a purchase order item differs from the unit price of a purchase requisition item. If you have configured, activated and defined tolerance limits in document types, variances are permitted in the tolerance limits. If the variance exceeds the tolerance limit, the system issues a warning. If you have defined a percentage-based and a value-based absolute tolerance limit, the strictest of the two variances will apply for this check.
Note
You can determine whether the system messages (601 and 602) appear as warnings or error messages in step "Define Attributes of System Messages".
To do this, go to the Materials Management IMG and choose Purchasing -> Environment Data -> Define Attributes of System Messages.
Requirements
The tolerance key must be defined in step Define Tolerance Key.
Activities
1. Define tolerance limits for each tolerance key.
2. Define the tolerance key in step Define Document Types.
Thx and best regards,
Ale

HT4759 what are the limitations for PC users using iCloud?

I am considering iCloud for storing music, photos etc. Are there any significant limitations for PC users? Our family employs a mix of Apple and PC devices.

Of course, iCloud does a better job on Apple devices like iPhone, iPad and Mac, because it seamlessly works with the pre-installed apps like Mail, Contacts, Calendars, Reminders, Notes etc., but you could also use some of the features on a PC. This guide shows you, how you could set up iCloud on a PC: http://www.apple.com/icloud/setup/pc.html
On a PC you sync iCloud Mail, Contacts, Calendars, and Tasks via Outlook, snyc Bookmarks and Photos.
Some other Services like iWork apps (Numbers, Pages and Keynote) or Find My iPhone are missing, but accessible through the website www.icloud.com (new Chrome or Firefox needed)
By the way, iTunes is still needed for managing your music library.

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

Set Tolerance Limits for Price Variance for PR missing from SPRO

I'm looking into setting up tolerance limits for price variance at the PR level. But when i navigate here:
SPRO > Materials Management > Purchasing > Purch.requisition > Set Tolerance Limits for Price Variance
I'm not seeing that available in SPRO. It's available for PO's but not PR's. We want to be able to set tolerances on the PR to be applied to the PO for non stock items (material master). Please advise

Hi,
There is no standard configuration option to set the tolerance limit at PR level. You may set the tolerance limit for PO and control the price change. If you want the same functionality at PR level, then you have to go for development. Please check whether the BAdI: ME_PROCESS_REQ_CUST can fulfill your requirement. You may set the tolerance limit in OLME - PO - Set Tolerance Limits for Price Variance itself and write the logic in the BAdI to check the price variance in PR based on the same configuration (table T169G and similar).
You may check the similar thread: PR VS PO Price Tolerance

Setting Default Preferences for All Users in Crystal Reports Server 2008 v1

We are currently looking to set the default preferences in the CMC for all of our users.
I did locate this page Link: [How to set default preferences for all users in Infoview 3.1/CRS 2008]
The first part of the thread did seem promising but I am unable to find the sample .jsp code that people recommended.
I would assume that this scenario is common enough that someone knows a way to set universal preference defaults.
Thank you

I thought I could just run it too but when I attempt to I get a Windows Script Host error:
Script: C:\User Prefs.vbs
Line: 1
Char: 1
Error: Expected statement
Code: 800A0400
Source: Microsoft VBScript compilation error.
I noticed the first most line seems to be markup for a web interface though I am not familiar with vbs so I may be wrong. I used the publishing wizard to put the script on the CMC to attempt to run it through the CMC but it still does not work.
