OLTP Database and DW Database Creation

Hi,
Is there any specific parameter we need to take care during creation of Database Instance on Exadata Machine for OLTP and DW types?
Thanks,

Hi Friend
Good Query.
Recommended for DWH :
1. Real Application Clusters
2. Partitioning
Recommended for OLTP :
1. Real Application Clusters
2. Advanced Compression
and we should evaluate all the database options to determine their value for your customer's specific situation.
In terms of Database Options : IORM (IO Resource Manager) + DBRM (DB Resource Manager) plays very big roles in Prioritizing the activities in OLTP and DWH enviroments based on LOAD.
Hope it helps...
Thanks

Database creation problems and parition consolidation

This is my first time on here so please look past my green-ness. =)
I Installed Oracle 8.1.7 successfully and opted to setup the database creation later so I could put the database on another partition. Well, I tried once to create the database on the partition I installed oracle onto (/oracle) but I had insufficient space, It said I needed 1.3 gigs. My "/database" partition is only a 1 gig parition (and /oracle is 2 gigs). My plan was of course, to seperate them.
Ok, I didn't see an option to create the db on another partition so I resigned to using /oracle. My question now is, is the 960 megs on /oracle enough to create the database? I used the custom setup so I could see how everything was broken down and I noticed that my rollback segment is 500 megs. Is this necessary? Can I get by with 100 megs and be fine? Also, if I did do this, I'd have approximately 100 megs free for data, this is enough I hope??
Lastly, I need to combine the partitions somehow without effecting /. The hard drive is broken down into:
gigs
5.5 /
2.0 /oracle
1.0 /database
Does anyone have any ideas? In windows, I used partiton magic but I don't know if there is a linux version.
One more thought (last one for real =), it had 50 megs allocated for it's shared memory pool. I'm assuming this will take away from the 128megs I have thus effectively making only 78 available to X, will this cause any noticeable problems other than a bit of slowdown? I have most if not all of my virtual memory free at all times. I know I should get more ram, but you know how the budget thing goes...
Any help would be greatly appreciated,
Rob

Try running the catalog and catproc sql scripts.
$ cd $ORACLE_HOME/rdbms/lib
$ svrmgrl
connect internal
@catalog
@catproc
That will set up all of the internal views and packages that
oracle needs to do DDL.

Adaptive Cursor Sharing and OLTP databases

Hi all,
I am reading a book about performance that affirms that, for OLTP environments, it is recommended to disable the Adaptive Cursor Sharing feature (setting the hidden parameter OPTIMIZEREXTENDED_CURSOR_SHARING_REL to NONE and the CURSOR_SHARING to EXACT). The book recommends this to avoid the overhead related to the feature.
I know that with this feature you can avoid the Bind Peeking issue as it creates more than one execution plan for the same query. So, it is really a good practice to disable it?
Thanks in advance.

OK, thanks for pointing out.
Getting back to your original question:
So, it is really a good practice to disable it?No, it is not, especially not without approval of Oracle Support.
Furthermore, I feel confirmed by that point from the book review by Charles Hooper as well as his additional points:
The book states that in an OLTP type database, “we probably want to disable the Adaptive Cursor Sharing feature to eliminate the related overhead.” The book then suggests changing the CURSOR_SHARING parameter to a value of EXACT, and the OPTIMIZEREXTENDED_CURSOR_SHARING_REL parameter to a value of NONE. First, the book should not suggest altering a hidden parameter without mentioning that hidden parameters should only be changed after consulting Oracle support. *Second, it is not the CURSOR_SHARING parameter that should be set to a value of EXACT, but the OPTIMIZERADAPTIVE_CURSOR_SHARING parameter that should be set to a value of FALSE (see Metalink (MOS) Doc ID 11657468.8). Third, the blanket statement that adaptive cursor sharing should be disabled in OLTP databases seems to be an incredibly silly suggestion for any Oracle Database version other than 11.1.0.6 (this version contained a bug that lead to an impressive number of child cursors due to repeated executions of a SQL statement with different bind variable values)*. (page 327)"

Oracle 9i installation hanging in "Clone Database Creation in Process"

Hi all,
I have been struggling in installing the 9i in my laptop.
Here is my setup,
OS: Windows Server 2003 Enterprise Edition SP2 in VMWare
Database: Oracle 9i 9.2.0.1.0
When it automatically comes to "Database Configuration Assistant", there are 4 steps.
Copying Database files
Initializing Database
Creating and starting Oracle Instance
Completing database creation
The 1st 3 steps has been completed and the installation just hangs at the last step when the completion rate is 88%.
Anyone got problem like this ?
Here are the details I have so far for the DBCA during installation process,
Listener Control complete.
Listener start failed. Listener may already be running.
Listener configuration complete.
Default local naming configuration complete.
Oracle Net Services configuration successful. The exit code is 0
Since I am completely new to installing DB, please help me to get rid of this frustration.
Thanks !
Regards,
Chris

Database creation with ASM using dbca

hi all,
i found the steps to create the database using ASM diskgroup.
but i received errors when configuring the FRA(flash recovery area), DBF(normal), +ARCH(archival dest),
i tried atleast 2 to 3 times from scratch but found the same error....................
ORA: 19624
ORA: 19870
here are the steps can somebody correct these steps..................
Create Virtual Disks from VM Ware software when server is down.
Choose Edit Virtual Machine Settings.
Click on Add button
Press Next and Highlight Hard Disk, then click Next
Check ‘Create a New Virtual Disk’
Choose SCSI as type
Select Size as 2 GB
Name the virtual disk as ‘ASMDBF1.vmdk’
Create additional disks as:
ASMDBF1.vmdk for DBF files
ASMDBF2.vmdk Failover group
ASMFRA.vmdk Flash Back Recovery Area
ASMREDO.vmdk Redo Log Area
ASMARCH.vmdk Archived Logs
•     Start up the server OraWorld1
•     Go to Disk Management and you will be prompted with a screen which should display all five disks with a check mark. Accept defaults and Click next.
•     On second script all five will be unchecked, click Next
•     Press Finish to complete and you should see all 5 disks as Type Basic Unallocated. For each of the disk perform:
1.     Right click, New Partition, Extended Partition and Finish
2.     Right click, New Logical drive, Do not assign drive letter nor partition it.
3.     From command prompt type Diskpart and enter Automount enable.
4.     From command prompt, configure basic CRS services as
5.     C:\oracle\product\10.2.0\db_1>localconfig add
6.     C:\oracle\product\10.2.0\db_1>localconfig add
7.     Step 1: creating new OCR repository
8.     Successfully accumulated necessary OCR keys.
9.     Creating OCR keys for user 'administrator', privgrp ''..
10.     Operation successful.
11.     Step 2: creating new CSS service
12.     successfully created local CSS service
13.     successfully added CSS to home
•     Launch DBCA and choose Configure Storage Management.
•     Select Create New group, choose stamp disks which will show you all of your five disks. Configure ASM links to all these disks as:
1.     ORCLDISKASMDBF1 \Device\Harddisk1\Partition1
2.     ORCLDISKASMDBF2 \Device\Harddisk2\Partition1
3.     ORCLDISKASMFRA \Device\Harddisk3\Partition1
4.     ORCLDISKASMREDO \Device\Harddisk4\Partition1
5.     ORCLDISKASMARCH \Device\Harddisk5\Partition1
Now make Change Disk Discovery Path as Null and you should see all disks.
Now create Disk groups as :
ARCH \\.\ORCLDISKASMARCH External 1GB
REDO \\.\ORCLDISKASMREDO External 1GB
FRA \\.\ORCLDISKASMFRA External 2GB
DBF (MAIN GROUP WITH 2 SUB-GROUPS) Must create as Normal Redundancy
DBFP \\.\ORCLDISKASMDBF1 External 2GB
DBFS \\.\ORCLDISKASMDBF2 External 2GB
You now have a running ASM instance on the server.
•     Checking ASM instance
You can always use DBCA to check settings of ASM.

Strange, those messages are RMAN backup errors -- are you trying to backup the database?
Or...if you selected "create starter database" it may be that dbca is not finding the backup files from the "demo" database.

But I didnt got the link of EM and when try to create a new connection in sql developer it is giving error ( Status : failure - Test Failed the Network Adapter could not establish the connection )
Thanks & Regards
Creation of the dbcontrol requires a connection via the listener. When configuring the dbcontrol as part of database creation, it appears that the dbcontrol creation step runs before the dynamic registration of the databsase with the listener is complete. Now that the database itself is completed and enough time (really, just a minute or two) has passed to allow the instance to register, use dbca or emca to create the dbcontrol.
Are you able to get a sqlplus connection via the listener (sqlplus scott/tiger@orcl)? That needs to be the first order of business.

Problem during Database Creation of 8.1.7 in Linux7.2

hello folks,
i am having a problem in creating database of 8.1.7 in Linux7.2 RedHat.
after successful installation,,and after even successfull listener configuration,,
when database creation assistant is creating database; On 82%
At "Initializing database"
it comes::
ORA-03114: not connected to ORACLE
and if we keep on ignoring it ,then it comes:
end of file communication channel.
plz help me what i would do,,

Hi,
seems that your oracle database went down. just check if oracle is running or not by using ps command.
if its not running go to $ prompt and start the database either using sys or internal user i.e
$svrmgrl
connect internal
$startup or startup force
let me know the result.

Error in installing Database Control with Database Creation Assistant

I'm trying to install the Database Control on Win2003 with the Database Creation Assistant. I get the following error. D:\oracle\product\10.2.0\admin\ECOMDB\pfile\init.ora (The system cannot find the path specified).
Our init.ora file is not in that path and our file is named initECOMDB.ora. How do I tell DBCA the correct path and file name to use?
By the way I'm a unix guy and this is the first time I've done Oracle on Windows. The database had been created by someone else and the files are sort of slung all over the place.
Replies appreciated.
Kirk

Open initECOMDB.ora, it may be calling D:\oracle\product\10.2.0\admin\ECOMDB\pfile\init.ora which does not exist. Change it to the correct directory or remove it if all the required parameters are already in initECOMDB.ora. The line to look for is ifile
BTW - if your database has already been created, you can create its database control from the command line:
emca -config dbcontrol db -repos create

Hi,
If you getting a problem with DBCA go for manually process:-
I had listed steps which I follow
Step 1: Decide on Your Instance's System Identifier (SID)
Step 2: Create the Initialization Parameter File
Note:- Name the copied init.ora file init<SID>.ora because this is the default naming convention that the Oracle server looks for when it tries to start up the instance ORACLE_HOME/dbs directory (exists over the prefered path)
Edit this file's parameters so that your database and your instance will run effectively on your system.
DB_NAME Must be set to a text string of eight characters or less. During database creation, the value assigned to DB_NAME is recorded in the database's datafiles, redo log files, and control files. If, when you attempt to start the database instance, the value of DB_NAME as recorded in the initialization parameter file and the database name in the control files are not the same, the database will not start.
DB_DOMAIN A text string that specifies the network domain where the database is created.
CONTROL_FILES Is assigned the comma-separated list of control file names to use for the new database. When you execute the CREATE DATABASE statement, the control files listed as values assigned to this parameter are created. If you fail to specify a filename for the CONTROL_FILES parameter, Oracle creates a file with a default operating system dependant filename.
DB_BLOCK_SIZE Specifies the standard block size of the database. This size is used in the creation of the system tablespace and by default in any other tablespaces created. Take care when determining what this value should be because after the database is created, the value cannot be changed.
UNDO_MANAGEMENT Determines whether the database starts in automatic undo management mode. A value of AUTO enables automatic undo management; MANUAL enables manual undo management mode. In 9i, AUTO is suggested, but MANUAL is default.
UNDO_TABLESPACE When the instance starts in automatic undo management mode, it needs to have a tablespace in which to store its undo information. The default is SYS_UNDOTBS and is automatically created if you execute a CREATE DATABASE statement with the UNDO_MANAGEMENT initialization parameter set to AUTO and no UNDO TABLESPACE statement in the CREATE DATABASE statement.
Step 3: Connect to and Start the Instance
Connect to the instance as SYSDBA either using operating system authentication or the password file method of authentication and start up the instance using the STARTUP command.
sqlplus '/ as sysdba'
If your parameter file is not in the default location or is not named init<SID>.ora, you may need to specify the PFILE clause in the STARTUP command for the instance to start.
Because you do not yet have a database attached to the instance, you need to start up the instance in NOMOUNT state:
startup nomount;
The instance is now started and ready for the CREATE DATABASE command.
Step 4: Issue the CREATE DATABASE Statement
create database mydb1 controlfile reuse
Logfile
Group 1 ('/mydb1/log1/log01a.log',
'/mydb2/mydb1/log01b.log') size 50M,
Group 2 ('/mydb1/log1/log02a.log',
'/mydb2/log1/log02b.log') size 50M,

Database creation in oracle 8.0.4

Hi,
I'm creating a database in Oracle 8.0.4. I choose the custom option to give all the parameters. One of these parameters is the password of internal user. I give it as oracle. After giving all the other parameters and then click on finish to create the database, i get ORA-01017 error and i'm being forced to abort the database creation.
After this error has occured, i've created another two databases with a different names and all went fine. I didnt have any problems while creating the databases. Again after the creation of the new databases, i tried to create the old database. Even then i got the same error.
can anyone let me know what might be the reason for this and the solution to overcome this problem.
Thanks in advance,
Jaikanth V Garlapati.

Found this in Oracle Doc,
NLS_DATABASE_PARAMETERS is the one you set when you do Create Database.
NLS_INSTANCE_PARAMETERS is the one you set in your spfile when you start instance.
So if you didn't set NLS_INSTANCE_PARAMETERS in spfile, then instance will start with NLS_DATABASE_PARAMETERS
And alter session will over write them all.
It's not new behavior in 10.2.0.4
==============================================
NLS Database Parameters
When a new database is created during the execution of the CREATE DATABASE statement, the NLS-related database configuration is established. The current NLS instance parameters are stored in the data dictionary along with the database and national character sets. The NLS instance parameters are read from the initialization parameter file at instance startup.
You can find the values for NLS parameters by using:
NLS Data Dictionary Views
NLS Dynamic Performance Views
OCINlsGetInfo() Function
NLS Data Dictionary Views
Applications can check the session, instance, and database NLS parameters by querying the following data dictionary views:
NLS_SESSION_PARAMETERS shows the NLS parameters and their values for the session that is querying the view. It does not show information about the character set.
NLS_INSTANCE_PARAMETERS shows the current NLS instance parameters that have been explicitly set and the values of the NLS instance parameters.
NLS_DATABASE_PARAMETERS shows the values of the NLS parameters for the database. The values are stored in the database.

Oracle 9i manual database creation on the Red Hat 9 Linux

I installed Oracle 9I on the Red Hat 9 Linux successfully with automatic database creation.
I tried to create second database manually and everything seemed to be fine until I issued create database statement. I got the following error:
ERROR at line 1
ORA-01092: ORACLE instance terminated. Disconnection forced.
Please help me to solve the problem.
Thank you,

Ok I am having the same exact problem and I am typing this into the shell before I run the installer.
export DISPLAY=yourdesktop:0.0
I thought that would fix the problem but it still hangs and gives the same message as the other guy gets. How can I solve this problem and get the installer running? I would really appreciate any help. This is the message I get:

Creation parameters not taking effect after database creation in 10.1.0.4

I created a database using DBCA, changed the default nls settings, then finished the database creation.
The alert log reports the parameters as different than the defaults
However, when starting the instance, the nls parameters are only set at the instance level and not the database level.
Has anyone seen something similar in 10.1.0.4?
Thanks

Oracle 11.1.0 + Solaris 10 10/08 + Database Creation failed

Dear all,
we have installed Oracle 11.1.0 on a Solaris 10 10/08 T5220 system and
the DB server installs fine.
When we try now to create the database by dbca the following errors
at the "Completing Database Creation" step were seen:
ORA-12801: error signaled in parallel query server P073.
ORA-00018: maximum number of sessions exceeded
ORA-06512: at "SYS.UTL_RECOMP", line 629
ORA-06512: at "SYS.UTL_RECOMP", line 671
ORA-06512: at line 1
We learnt from the net that an increase of the SESSIONS / PROCESSES
parameters in the init.ora file should help us.
Regardless which number for these parameters we used
(PROCESSES = 1000 or 5000 or 10000) the errors above still occured.
We turned also off parallelism but without success!
Is this a bug and/or is there any other method to create the database
without any errors?
THX,
Rainer

I got it now by putting the "sessions" parameter into the template file General_purpose.dbc
used by dbca.
By the way:
I tried also to install Oracle 11g on a Sun with only 4gb RAM
under Solaris 10 10/08. I got the error
ORA-27102 Out of Memory
Does this mean that we need more physical RAM now?
