No of concurrent users on oracle 10g
Hi Guru's,
We have a requirement where 200 + user will have a connection to our database at a point of time. We have windows 2008 + oracle 11.1 in our envirnment.
Now my question is ..What steps do i need to take that all connection are taken care by databse and no connection gets failure message.I tried this by 100 connnection but after 100 it is giving error .(listener error..)
Please let me know in case any more detail is required from my side.
Thanks
Vivek
As you never posted what listener error you got, my guess is you hit ora-12500, which usually means the maximum number of threads for the Oracle process is reached.
You can configure the maximum number of threads in Windows, but I do not know from the top of my head how, so I suggest you visit http://technet.microsoft.com

No of maximun users in oracle 10g express edition
what is the maximum number of concurrent users (session) in oracle 10g express edition.
coz right now, we have one server with oracle 10g express edition, and a front end application of asp.net (.net 1.1)The only limit that Oracle places on the number of concurrent users on an XE database is through the limit of 1GB of RAM. You can have as many concurrent sessions as you can open in 1GB of RAM.

Create a new user for oracle 10G ASM instance with sysdba system privilege
Hi,
In our Golden Gate Project, we require the SYS user credential to connect to the Oracle 10g ASM instance to read the database transaction logs.But our client is not providing the SYS user credential to connnect to ASM instance.
I'm getting the error message "ORA-01109: database not open",When I tried to create a new user using the below the steps in oracle 10g ASM instance
1. Login using "sqlplus / as sysdba"
2. Create user <username> identified by <password>;
But in oracle 11g ASM instance, I'm able to create new user by connecting the ASM instance with SYSASM role without issues.
Is there is any workaround to create a new user with sysdba system privilege in oracle 10g ASM instance?.
Thanks in advance .Hi,
Recreate the password file for the ASM instance as follows:
Unix:
orapwd file=<ORACLE_HOME>/dbs/PWD<SID> password=<sys_password>
Windows:
orapwd file=<ORACLE_HOME>/database/PWD<SID>.ora password=<sys_password>
Now sys password is reset, we are ready to use sys for ASM management. I decided to create another user ASMDBA as I tried above.
SQL> create user ASMDBA identified by test01;
User created.
SQL> grant SYSASM, SYSOPER to ASMDBA;
Grant succeeded.
SQL> select * from v$pwfile_users;
USERNAME SYSDBA SYSOPE SYSASM
SYS TRUE TRUE TRUE
ASMDBA FALSE TRUE TRUE
Please see this link : http://orachat.com/how-to-change-asm-sys-password-creating-sysasm-user-11g/
Thank you -
What is the version of grant alter table, drop table to user in Oracle 10g?
Hi,
Oracle support "grant alter table and drop table" before, but I get the "invalid privilege" error in Oracle 10g. Oracle 10g have the "DROP ANY TABLE" and "Alter any table". Is these two means can drop and alter tables belonging to other users? How do I grant the total control (CRUD) of tables in the owner's schema to the owner in Oracle10g?
Thanks,
JiangCREATE TABLE privilege grants complete control on owner's tables :
SYS@db102 SQL> create user test01 identified by test01;
User created.
SYS@db102 SQL> grant create session, create table to test01;
Grant succeeded.
SYS@db102 SQL> alter user test01 quota unlimited on users;
User altered.
SYS@db102 SQL> conn test01/test01
Connected.
TEST01@db102 SQL> create table test(a number);
Table created.
TEST01@db102 SQL> alter table test add(b varchar2(100));
Table altered.
TEST01@db102 SQL> drop table test purge;
Table dropped.

Max Concurrent Users for Oracle 8i
I am trying to find out information (white paper) that states how many concurrent users 8i can handle. Does anyone know of somewhere to get this data?
Thanks in advance,
JSCan you post the entire dump from the console?
Where are you getting the term "Concurrent Users"? Concurrent Users is a term Oracle used to use (or maybe still do) when licensing products. I'm just interested where you are seeing this from. -
Heavy CPU consumer/user in Oracle 10g
Hi,
OS linux
DB 10g
How do I find the program/user that eats a lot of CPU inside the oracle engine process?
I tried to run "top" linux command, and I saw the my CPU usage is 100% and the user was the oracle kernel.
I been monitoring the performance of our DB server Linux using "top" command, and I got this monitor dislay:

How do I find the culprit program at (Oracle Level) who is hugging all the CPUs?
Thanks a lotoradev2 is not the program, it is the LINUX oracle user id.
the process is under the 'command' column and is 'oracle' - this usually means an oracle server process ( i don't know what you mean by an oracle 'kernel' incidentally)
if you do a ps listing for the process - e.g
$ ps -ef | grep 12778
you will get a start time for the process which MAY give you a clue.
otherwise you must use your documentation to find out about the sys view v$process - usually the SPID column is the LINUX process id - in your case, 12778
you usually link v$process to v$session. Best of luck.

Regarding accessing SQL query issued by any user in Oracle 10g
Hi all,
i want to know the queries issued by various users accessing a database...
But the in view DBA_AUDIT_TRAIL,I was getting empty value...(in SQLTEXT column) ...how can i get this value...
Thanx
in advance..Straight from the documentation :
The SQL_BIND and SQL_TEXT columns are only populated if the AUDIT_TRAIL initialization parameter is set to db,extended.In addition, you have to make sure you issued the AUDIT command on the objects you would like to AUDIT access on.

Top SQL by DB user in Oracle 10g DB Console
Is there a way to filter Top SQLs on 10g DB Console by a specific DB User? I know you can get all the SQLs by a specific user from Search Sessions, but it doesn't rank them by CPU usage. Any help is greatly appreciated.
nice idea, because SQL itself doesn't contain info about session executing it.
See Top SQL/Consumers
in OEM 10: goto Perfomance - Top Activity - here you can see Top SQLs (left side) and Top Sessions (right side) and ! if click on SQL ID from Top SQL you can see sessions executing it on Activity page. -
Hi friends,
I had already purchase oracle 30 users license and want to use in the platform where more than 100 work stations accessing the server. Is it neccessary to buy 100 user license to access the database at the same time, OR everybody can hook on to database only 30 users at a instant can play with database.
Pls. clearify me with your practical idea.!!If you can get it to work, the Designer Web Assistant should provide unlimited user, read-only access via a web-browser. That was one of our reasons for installing it. However, I cannot determine when the 6i version will be available, and it has not executed successfully yet.

Hi,
When i changed my sysman and dbsnmp password, these users are frequently locking.
For sysman password change i do the following steps.
1) emctl stop dbconsole
2) change password of sysman and dbsnmp from sql
3) Post sysman password change to emoms.properties file
4) Post DBSNMP password change in targets.xml
5) emctl start dbconsole.
DBSNMO AND SYSMAN users were locked.
Stop dbconsole again
Unlock the user sysman and dbsnmp
then again restart dbconsole
Sysman user locked
Another thing do we need to have same password for dbsnmp and sysman
Regards,
irfanb146Now Sysman and DBSNMP users are unlocked after i made the password of sysman change again and they are not locking.

1 How to Display Iconic Images Using Forms 9.0.x/ 10.x?
When running an Oracle Forms 9i/10g application the icon files used must be in a web enabled
format such as JPG or GIF (GIF is the default format) (This is unlike older versions of forms running in client-server mode when the file format is .ico.)
Icon image files can either be retrieved by Forms as individual files on the filesystem or from a Java Archive (JAR file).
If an application uses lots of icon images it is recommended that they are stored in a JAR file to reduce the number of HTTP round trips.
Reference:Note 232413.1 How to Deploy Iconic Images via a JAR File in Forms 9i/10g?
The example below details steps to configure iconic images as individual gif or jpeg files.
It is a first approach recommended for initial testing and understanding.
Example:
========
This document has been written for use with both Windows and UNIX operating systems: Windows will use the "\" character to delimit directories and UNIX uses the "/" character. Any other differences are noted in the document.
1) Determine the physical location of the icons on your web server. For this example, assume that the icons are stored in D:\Myfiles\icons.
2) Create the virtual directory in the forms90.conf file that point to the location of your Forms 9i/10g icons. This file is located in:
$ORACLE_HOME\forms90\server\forms90.conf
To define a virtual directory forms90/icons, use the following syntax:
# Virtual path for ICONS (used to show icons in a form ) AliasMatch ^/forms90/icons/(..*) "D:\Myfiles/icons/$1"
Below is an example of the forms90.conf after it has been modified to include the /forms90/icons virtual directory.
# Virtual path mapping for Forms Java jar and class files (codebase) AliasMatch ^/forms90/java/(..*) "E:\IASR2\APP/forms90/java/$1" # Virtual path for JInitiator downloadable executable and download page AliasMatch ^/forms90/jinitiator/(..*) "E:\IASR2\APP/jinit/$1" # Virtual path for runform.htm (used to run a form for testing purposes) AliasMatch ^/forms90/html/(..*) "E:\IASR2\APP/tools/web90/html/$1"
# Virtual path for ICONS (used to show icons in a form ) AliasMatch ^/forms90/icons/(..*) "D:\Myfiles/icons/$1"
( For 10g use instead of "forms90" -> "forms")
3) Direct forms to use the /forms90/icons or /forms/icons virtual directory when running on the web by modifying the Registry.dat file in the $ORACLE_HOME\forms90\java\oracle\forms\registry or $ORACLE_HOME\forms\java\oracle\forms\registry
directory. Note that for UNIX, both the path name and file name are case sensitive. You must specify "Registry.dat".
Modify the default.icons.iconpath entry as follows: default.icons.iconpath=http:///forms90/icons/ or default.icons.iconpath=http:///forms/icons/
If the URL used to bring up forms on the web is: http://abc.oracle.com:7778/forms90/f90servlet or http://abc.oracle.com:7778/forms/frmservlet
Then the entry required for the Registry.dat will be: default.icons.iconpath=http://abc.oracle.com:7778/forms90/icons or default.icons.iconpath=http://abc.oracle.com:7778/forms/icons default.icons.iconextension=gif
4) Now use EM Website to: a) Restart the OC4J-BI-Forms Instance b) Restart the BI-FORMS HTTP Server Instance.
5) Verify that the virtual directory has been defined properly and that the icons can be viewed in a browser.
Assuming that exeqry.gif exists in the D:\Myfiles\icons directory, the following URL should show the icon:
http://abc.oracle.com:7778/forms90/icons/exeqry.gif or http://abc.oracle.com:7778/forms/icons/exeqry.gif
6) Check the form : http://abc.oracle.com:7778/forms90/f90servlet?form=D:\Testcases\F90\ICON_CHECK_IASR2.fmx or http://abc.oracle.com:7778/forms/frmservlet?form=D:\Testcases\F10g\ICON_CHECK_IASR2.fmx
CHECKLISTS
=============
Icons do not appear in the browser using the URL:
o Verify that you are using the correct machine name and port for the OC4J_BI_Forms object.
o Check the virtual directory name to make sure that there are no typographical errors. o Check for typographical errors in the forms90.conf or forms.
conf for the virtual directory. o Check the name of the icon on the file system. If the file is saved as Exeqry.gif, then it will not be found using the URL http://abc.oracle.com:7778/forms90/ Close all your browser sessions and open a new browser window.
Execute the URL to bring up from the Form Builder runtime or from the browser.
( For 10G use "forms" instead of "forms90")USEFUL REFERENCES:==================
