Oracle 10g System Statisctics

Hi,
I want to know if System Statistics (CPU and I/O usage) for CBO are automatically taken and loaded in Oracle 10g or I have to schedule it manually?
can anybody help me?
Thanks in advance,
Gerald.

Basic system stats are generated at instance startup in 10g. Ideally you should still do the manual gather for better system stats values based on you workloads
You can check system stats in SYS.AUX_STATS$

Oracle 10g - System Statistics

Hello guys,
i've got a question foru you :-))
If i generate new system statistics (cpu load, i/o load, etc.), are the execution plans in the sga going invalid?
Some time ago i tested it with new statistics on tables/indeces and if i generate new statistics for tables/indeces, all execution plans that refer to the object (table/indeces) are going invalid.
But under 10g, what about system stats? Are all execution plans going invalid, if new system statistics are generated? The system stats are needed to decide which access path is better.. so it would be suggestive .... i believe this would cause massive parse load.
Thanks for your answers
Regards
Stefan

From the Performance Tuning Guide, Chapter 14 Managing Optimizer Statistics
Unlike table, index, or column statistics, Oracle does not invalidate already parsed SQL statements when system statistics get updated. All new SQL statements are parsed using new statistics.

Oracle Database Migration(Oracle 9.2.0.4 to Oracle 10g)

I want to migrate my database from Oracle 9.2.0.4 to Oracle 10g XE, is there any method to migrate the database successfully..?
My plan is to empty the existing database on the Oracle 10g XE then export the database from old machine(Oracle 9.2.0.4-including privilages,users,tables,etc) and import it to the new machine(Oracle 10g XE), but i was worried if I empty the existing database(Oracle 10g XE), all the tables will be gone(including Oracle 10g XE system table that do not exist in older oracle version) and after I import the database to Oracle 10g, I afraid the database will encounter any problem because I've deleted the Oracle 10g system tables.
Anyone can give me suggestion on how to migrate the database successfully..?
Thank you.

What's the Edition of your Oracle 9.2 ?
I don't think do full export/import from 9i to Oracle 10g XE is good idea. The chance you will have problem after import is very high.
Instead, you may want to consider do schema user level exp/imp.
Don't drop any thing belongs to SYS and SYSTEM on 10g XE. Actually you only need to drop the sample users like 'HR'

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

I have installed oracle 10g in my winxp machine. i am using enterprise manager. i am not able to shutdown the system as it asks for os username and password. i have provided my os username and password but eerror persiste. somebody pls help me to get rid

I have installed oracle 10g in my winxp machine. i am using enterprise manager. i am not able to shutdown the system as it asks for os username and password. i have provided my os username and password but eerror persiste. somebody pls help me to get rid of this.

Here I am using Java Type IV for database
connection.
So,there was no necessity of creating DNS.How your app communicates with db shouldn't matter for the end user. Still, you may want to use a functional network name also for the thin client driver connection string.
So,is there any other way to solve this problem.What is the problem really? Do you not use dns for network naming? Maybe you have to manage the hosts file on every client then.

How to Install Oracle 10g in Windows 7 Home premium 64bit operating system

Hi,
I am using Windows 7 Home premium 64bit operating system. While i was installing oracle 10g i got error and not able to install. How to install the Oracle 10g databse on this operating system. Is there any patch to install this or i have to use other version of oracle with window 7 operating system?
Thanks in advance
Mayank Adhikari

The argument would be who wants to install Oracle database on Windows 7. I think most probably by the developers who wants to "Try" something prior deal with a production database, right?
For a developer, installing database using the hack is more than NOT having a local database running from the local system. I installed all the products mentioned with windows7bugs post and used the following tools to successfully connect and retrive data from the database instances.
Toad 9.7.x.x
SQL Developer
SQL/Plus
Developer 6i (Another hack, please check this link http://windows7bugs.wordpress.com/2010/03/01/installing-oracle-developer-forms-reports-6i-on-windows-7-64bit/).
I think the discussion about whether all the features of client/server are still available with such a hacked installation is meaningless as far the information requested was strictly for Windows 7, not for a Server OS.

You should ask Oracle support for help. There's only one entry for this error stack (Bug 3361288 - Export of XMLSCHEMA may fail with ORA-24324 in UTF8), but it should have been fixed for your DB version and , as far as I can see, you don't have a Unicode database.

Oracle 10g on Windows 2003: Can't start with any account but Local System

Fresh install of Oracle 10g on Windows 2003. I install as a member of the local admin group and everything works great. The various services are starting as Local System, though, and I'd prefer to set them up to start as a specific domain user account.
When I make that change, however, I can't get any of the Oracle related services to start. I've added this domain user to the local ora_dba group on my server, given it the ability to log on as a batch job and log on as a service in the local security policy. Doesn't seem to help.
I saw a thread that implied using a domain user account wasn't supported (didn't seem right to me, but what the hell), so I created a local user account and tried that. Same result.
Something I'm missing?
Thanks.

What is missing, I suspect, is reading the installation docs.
http://docs.oracle.com
If that doesn't work then come back and ask specific requestions referencing the appropriate document and naming the actual version you are trying to install (ps 10g is a marketing name not a version number).

MBRC and SYSTEM STATISTICS in Oracle 10g database.

Hi All,
I am performing database upgrade from Oracle 8i Solaris to Oracle 10g HP-UX using exp/imp method.
But i do have some doubts regarding MBRC and System statistics.
MBRC in Oracle 10g is automatically adjusted if MBRC parameter is not set, but i found value 128 as shown below.
SQL> select * from v$version;

db_file_multiblock_read_count        integer                          128Also i performed one simple full table scan to test it...but db file scattered read is performing on 128 blocks. So i dont think 128 is suitable and is automatic, i mean MBRC is not set accrodingly it always uses 128.
Does this MBRC value affects whole database performance?
Regarding SYSTEM STATISTICS i found below result:

Connect Non SAP Oracle DB and MSSQL DB to SAP BW 7.0 Orace 10g system

Hi All,
Well I have a scenario, where I have to connect Non SAP Oracle 9i DB and MSSQL DB (2000, 2005) to SAP BW 7.0 Orace 10g system.
There are all together 4 Non SAP systems to be connected.
Up till now I have understood that in order to have to integrate Oracle 9i to BW system - TSNNames.ora has to be updated, then create new Logical system, then Create Source system in RSA1 with all the required information, Create user at Oracle 9i end.
As far as MSSQL Server is concerned - Client Software + DB Shared Library has to be installed in BW server.
Could anybody please guide me in the complete Basis Activities including above to complete the process.
I tried to create Source System, the initial screen has fields - Logical System, Source System & Type and Release.
I have created the Logical system through Tcode SALE
How to create Type and Release - for DB Oracle 9i & MSSQL 2000/2005.
Does OS version of DB & BW also matters ? Do we need to have that information as well.
Thanks & Regards

way of an Interchange). Start the listener on the remote machine.

Connetion of BI 7.0 to external oracle 10G R2 database system

Dear Experts,
We have BI 7.0 system with MS SQL server as database and we want to
connect it to database Oracle 10G R2.For that we followed the following
procedure.
1) In order to connect to the enterprise database, Oracle 10gR2 client
(runtime option should be fine) needs to be installed (you need admin
rights) on the machine where the connection is requested. -->We have
installed it.
2) You should make sure that Database server is reachable from the BI
SAP machine (ping, telnet, traceroute, etc).--> The tnsping is reaching
the database host.

the same.
Now after doing the above activities when we tried to create
sourcesystem in RSA1 we got the error as :

Dear Experts,
We have BI 7.0 system with MS SQL server as database and we want to
connect it to database Oracle 10G R2.For that we followed the following
procedure.
1) In order to connect to the enterprise database, Oracle 10gR2 client
(runtime option should be fine) needs to be installed (you need admin
rights) on the machine where the connection is requested. -->We have
installed it.
2) You should make sure that Database server is reachable from the BI
SAP machine (ping, telnet, traceroute, etc).--> The tnsping is reaching
the database host.
3) Then a TNS connection name needs to be created --> We have created
the same.
Now after doing the above activities when we tried to create
sourcesystem in RSA1 we got the error as :
Cannot acces source system <External_dbname>
In the system log it is giving error as :
Database error 12154 at CON
ORA-12154: TNS:could not resolve the connect identifier
