Creating a New database instance

Hello experts,
I need to create a new database instance and later drop my old one.
Can anyone send me detailled guidelines on how i should do this without experiencing any performance degradation and also alert me on anything that can go wrong.
thanks in advance

I suspect you'll get more help if you address this question to the Linux forum. This question appears to have nothing whatsoever to do with the Oracle ODBC driver.

Which rights are required for a user to create a new database instance

Hi,
Which user can create a database instance? Is it Admin or any user? or Is it must to have admin rights on the <oracle_home> folder in order to create a new database instance?
Please let me know what rights the user should have for creating a new database instance.
Regards,

If I login to machine as a Guest user or I am not a owner of Oracle software then in the both cases I couldn't able to create a new database instance. Am I right?
Please suggest me.

How to create a new database instance from an existing one?

Hi, I basically want to create a snapshot of a production
instance (version 8.1.7) for querying purposes. Would anyone
tell me the steps involved? What I did as follows:
1. Copy all data files to a new location
2. Modify init.ora accordingly. I believe there is no separate
control file for this version.
But when I startup the instance, got this error:
ORA-01103: database name 'TRITON' in controlfile is not 'HERCULE'
What is missing? Do these data files contains links to the
previous instance name?
Thanks for any help.

Hi All,
I need some help in recreating new database instance.
Here are the steps I have done so far:
1. Created a database with name 'LASTDB' using DBCA
2. Connected to RMAN.
3. RMAN>SET DBID=******; (of the source database)
4. Connect to target. RMAN>connect target SYS/*****;
5. Executed controlfile restore on RMAN.
RMAN>Run{
Allocate channel D1 Type DISK;
Set controlfile autobackup format for device type DISK to
\\<ip_address>\Backup\Prod\%F;
Restore controlfile from autobackup;
6. RMAN> ALTER DATABASE MOUNT;
Now got an error saying ORA-01103: database name PRODDB' in control file is not LASTDB
I tried using NID to change the database name but it's throwing an error that database is not mounted.
I have browsed a lot and found that I need to recreate a control file of the production database using ALTER DATABASE BACKUP CONTROLFILE TO TRACE and should edit the trace file. But it also says to shutdown the source database which is production database and I cannot try that.
Also I have tried adding a line to init.ora like lock_space_name = LASTDB. Also tried replacing everything from LASTDB to PRODDB but that didn't work either.
I have been trying to find a solution to this. Please bear with me as I'm a beginner and please let me know how I can fix the error.

i want one more instance of database.Can you perhaps explain why? I have a fair share of production and development servers - and not a single one of them needs to run more than one database instance.
So I'm interested in what requirement you are trying to satisfy by using two database instances on a single platform.
Oh yeah - if you want to create a custom XE instance (different SID, different tablespace sizes, more/less PL/SQL stuff installed, hack standard), make a copy of your XE db creation script (in your XE's +$ORACLE_HOME/bin+ and called createdb.sh ) and modify that for your needs.
PS. even with a different SID, only a single XE instance can be run at a time - you can however have 2 different ones defined and then use one at a time (e.g. testing international settings, init param differences, etc.)

Problems wit creating a new database on solaris wit dbca ORA 09925/ORA-1031

Hi Oracle users,
I'm using Oracle 10gR2 on Solaris and try to create a new database

I'm using dbca for that task. After making all the settings I get the error
ORA-09925 and then ORA-1031.
For the second error I found the advice to run te root.sh to be sure that
all user privileges for local logins are correct.
But tis didn't help.
Do you have an advice for me ?

Restoring a RMAN backup to a new database instance

Hi Mates,
I have an issue with restoring a RMAN backup that i have with me to a new database instance. What i have with me are:
1. Backup of SPFile. (O1_MF_NCNNF_CTLFILE_BU_92DVGYO2_.BKP)
2. Backup of Control file (O1_MF_NNSNF_SPFILE_BU_92DVGW9H_.BKP)
3. Full database backup (O1_MF_NNSNF_FULLPROD_BU_92DVGW9H_.BKP)
I have received these files from a customer environment and I need to restore these to a new database instance in a local machine. I have given a attempt as follows (in Oracle 10g):
1, Created a new database instance (Test75) using Oracle Database Configuration Assistant
2. SET ORACLE_SID = Test75
3. Connected to this instance using RMAN
4. Tried to restore the SPFILE from the received BKP file.
I am getting errors and cannot proceed. I am not sure whether I am executing the correct steps. Please help me out by telling me how should I achieve this.
Thank you.

1. Backup of SPFile. (O1_MF_NCNNF_CTLFILE_BU_92DVGYO2_.BKP)
2. Backup of Control file (O1_MF_NNSNF_SPFILE_BU_92DVGW9H_.BKP)
The first backuppiece looks like a ControlFile and the second one looks like an SPFILE'
>I am getting errors and cannot proceed
What is the error ? (I assume that you tried to restore the SPFILE from O1_MF_NNSNF_SPFILE_BU_92DVGW9H_.BKP
Note that you also have to SET DBID before you restore the controlfile

Create a new Database in an other server using a copie of RMAN backup

Hi all,
I want to create an other instance for our production database. We have disk and tape in rman backup. My question is can i create a new database using our disk backup in an other server?
If some procedure or steps is there, email it to my adresse [email protected]
Hamid.
Thanks

By means of the use of Recovery Manager it is possible to duplicate a database out from a previously taken rman backup. The method will be outlined in the next few lines.
Let's assume a source database named SRCDB and the target database, named GEMINI. A unix like environment is assumed, but it can be implemented on windows as well, just beware of the particular Oracle implementation on a windows platform (orapwd file name, service creation, path format)
1. Create a password file for the Cloned (GEMINI) instance:
orapwd file=/u01/app/oracle/product/9.2.0.1.0/dbs/orapwGEMINI password=password entries=10
2. Configure tnsnames.ora and listner.ora
Properly identify the database at the tnsnames.ora and have the instance manually registered against the listener.ora files, both files located at the $ORACLE_HOME/network/admin directory.
2.a Manually register the database against the listener (listener.ora)
(SID_DESC =
(ORACLE_HOME = /u01/app/oracle/product/9.2.0.1.0)
(SID_NAME = GEMINI)
2.b Added the target GEMINI to the tnsnames.ora
GEMINI =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = myhost.mydomain.com)(PORT = 1521))
(CONNECT_DATA =
(ORACLE_SID = GEMINI)
2.c Reload the listener
lsnrctl reload
3. Create a new init.ora for the cloned database.
Next create an init.ora file for the cloned database. In case the same paths cannot be used on the target host, either because it is the same source host or because those paths are not reproducible on the target, then DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT may be required to be defined
DB_NAME=GEMINI
CONTROL_FILES=(/u02/oradata/GEMINI/control01.ctl,
/u02/oradata/GEMINI/control02.ctl,
/u02/oradata/GEMINI/control03.ctl)
# Convert file names to allow for different directory structure.
DB_FILE_NAME_CONVERT=(/u02/oradata/SRCDB/,/u02/oradata/GEMINI/)
LOG_FILE_NAME_CONVERT=(/u01/oradata/SRCDB/,/u01/oradata/GEMINI/)
# block_size and compatible parameters must match those of the source database
DB_BLOCK_SIZE=8192
COMPATIBLE=9.2.0.0.0
4. Connect to the cloned instance
ORACLE_SID=GEMINI; export ORACLE_SID
sqlplus /nolog
conn / as sysdba
5. Create an SPFILE based on the init.ora
CREATE SPFILE FROM PFILE='/u01/app/oracle/admin/GEMINI/pfile/init.ora';
6. Start the database in NOMOUNT mode:
STARTUP FORCE NOMOUNT;
7. Connect to the TARGET, CATALOG and AUXILIARY databases.
By means of the rman three connections are open, one for the Source Database (SOURCEDB), another for the Catalog database (RCAT), and one more for the cloned database (GEMINI)
ORACLE_SID=GEMINI; export ORACLE_SID
rman TARGET sys/password@SRCDB CATALOG rman/rman@RCAT AUXILIARY /
8. Complete or Incomplete clone (recover)
From the rman the database using one of the following commands:
8.a Clone the database by means of a complete recover.
DUPLICATE TARGET DATABASE TO GEMINI;
8.b Clone the database up to a defined point in time in the past by means of an incomplete recover
DUPLICATE TARGET DATABASE TO GEMINI UNTIL TIME 'SYSDATE-2';
9. Process finished.
Once the process is finished, the newly created GEMINI database is ready to be used as an independent new cloned database.

Creating a new database containing part of an existing database,same server

Hi All Experts,
I have a problem. I am trying to create a new database on a server which already has a database (named qadb10g) running on it. I want the new database to contain only a few tablspaces of the "qadb10g" database. I tried this approach.
1. Take an RMAN backup of the desired tablespaces from the source database (qadb10g), including system and undo tablespaces as well.
2. Use "SET NEWNAME FOR DATAFILE ..." RMAN commands to restore all the data files in the new disk location on the same server.
3. Run "ALTER DATABASE BACKUP CONTROLFILE TO TRACE" command in the "qadb10g" database to generate a "create controlfile...." script.
4. Edit the resulting file (from step 3) to change file locations and database name, instance name, etc.
5. Create a new init.ora file for the new database.
6. From an sql*plus session, with "ORACLE_SID" already set to new database name, run the "create controlfile ..." script which we generated and changed above.
I performed steps 1-5 successfully, But when I ran the step 6 command, I got an error saying "Datafile Header contains database name 'qadb10g' which is not maching the <newdb name> .....".
This means, the database datafiles which were backed up and restored from the 'qadb10g' database still contain the same db name in their header and this is preventing new control file from being created. So, the new datbase cannot be created. Can anbody help me how to resolve this problem???
Any urgent help would be greatly appreciated. Thanks in advance.

At Step 4, did you use the SET <newdbname> in the create controlfile script ?
At Step 5, did you change the db_name in the pfile ?
nid is the new and easier way to change the database name.

About spfile creating in oracle 10g while creating a new database

hi everyone,
i had this problem while i was creating a new database in oracle 10g.when running the database script, it gives an error about invalid option for create temporary tablespace. is it necessary to have an spfile created in 10g. when the script was not working,we tried to create spfile which gives error tht it does not match the parameter db_name. its taking the default db_name=orcl itself..tis not taking our new db name.
im creating it manually through sql prompt not through DBCA.the problem is that its still accepting the default db name. please send me the solution with syntaxes.
thanx

first of all, thanx for giuding me as im a student doing a course in this
what abt the creation of spfile.. in a documentation for steps in creating database, they have mentioned it as recommended in creating spfile.here are some notes regarding this ....for oracle 10g
Step 5: Create a Server Parameter File (Recommended)
Oracle recommends that you create a server parameter file as a dynamic means of maintaining initialization parameters. The server parameter file is discussed in "Managing Initialization Parameters Using a Server Parameter File".
The following script creates a server parameter file from the text initialization parameter file and writes it to the default location. The script can be executed before or after instance startup, but after you connect as SYSDBA. The database must be restarted before the server parameter file takes effect.
-- create the server parameter file
CREATE SPFILE='/u01/oracle/dbs/spfilemynewdb.ora' FROM
PFILE='/u01/oracle/admin/initmynewdb/scripts/init.ora';
SHUTDOWN
-- the next startup will use the server parameter file
EXIT
the error : db_name does not match with the parameter.
its still taking the default orcl database name

HELP: Problem creating a new database in Oracle 9i

I am having difficulty in creating a new database in Oracle 9i, on Windows 2000. I would be obliged if somebody can go through the posting below and guide me as to what mistake I am making or what is the source of the problem:
I reproduce the steps taken by me.
I have decide the database to be called Mydb. I have made the following directories:
-- d:\mydb
-- d:\mydb\data
-- d:\mydb\control
-- d:\mydb\log
-- d:\mydb\bdump
-- d:\mydb\cdump
-- d:\mydb\udump
-- d:\mydb\archive
-- d:\mydb\pfile
-- d:\mydb\scripts
-- d:\mydb\exp
I copied the initoracle.ora file to d:\mydb\pfile\initmydb.ora, and made the following changes to it:
-- db_name = mydb
-- instance_name = mydb
-- control_files = ("d:\mydb\control\control01.ctl")
-- background_dump_dest = d:\mydb\bdump
-- core_dump_dest = d:\mydb\cdump
-- user_dump_dest = d:\mydb\udump
-- remote_login_passwordfile = exclusive
Also, I created a text file called d:\Oracle\Ora90\DATABASE\initmydb.ora with the following contents:
ifile=d:\mydb\pfile\initmydb.ora
At DOS prompt, I run the following command:
set oracle_sid=mydb
I run the ORAPWD utility to create internal password file at the command prompt.
d:
cd \oracle\ora90\database
orapwd file=pwdmydb.ora password=panther entries=25
I create a Windows service for the database as follows:
oradim -new -sid mydb -startmode a -pfile d:\mydb\pfile\initmydb.ora
I get connected:
sqlplusw /nolog
connect sys/change_on_install as sysdba
startup nomount # pfile=d:\mydb\pfile\initmydb.ora
create database mydb

Now I get the following error:
create database mydb
ERROR at line 1:
ORA-01092: ORACLE instance terminated. Disconnection forced
The data files, control file, redo log files are all created. But the above error comes, and I am unable to start the database. What is the reason?
Thanks in anticipation.
PS

Hi DENIS,
I have executed the following commands (which are in a script file),
1. sqlplus /nolog
2. connect sys/change_on_install as sysdba
3. create database ...
4. ...
When I execute the 3rd command, I get an error message as "ORACLE TERMINATED FORCED" and it will end the session. So when the next set of commands in the script are executed, I got the error saying "DATABASE NOT OPEN".
How to rectify this problem.
Thanks in advance,

How do l create a new database in Oracle 10g Express

How do l create a new database in Oracle 10g Express, other than the one that is created on installation?

Hello,
You cannot create a second XE database on the same server.
But, Oracle database can support as many Schema as you want.
"Oracle database" is like "SQL Server Instance" and "Oracle Schema" is like "SQL Server database". I means by this shortcut that for
the end users accessing to different Schemas looks like accessing to different databases.
You can have several applications on the same database. Each application has its own Schema and Datafile (Tablespace) structure.
So on your XE database you can add a new Tablespace and create a new User/Schema as follows:
sqlplus /nolog
connect / as sysdba
create tablespace {color:red}new_tablespace_name{color}
extent management local autoallocate
SEGMENT SPACE MANAGEMENT AUTO
datafile '{color:red}complete_datafile_name{color}' size 100M autoextend on next 10M maxsize unlimited;
create user {color:red}new_schema_name{color} identified by {color:red}password{color}
default tablespace {color:red}new_tablespace_name{color}
temporary tablespace TEMP
quota unlimited on {color:red}new_tablespace_name{color}
grant connect, resource to {color:red}new_schema_name{color};Then you can connect to this new User/Schema as you defined it and create your new structure and load datas.
Hope it can help.
Best regards,
Jean-Valentin

There might be other parameters that need increasing as you add instances. Check Oracle and linux documentation.

Windows could not start DBConsole for new database instance

Hi,
I am getting this error "Windows could not start the OracleDBConsoleOracleInstance2 on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the system vendor, and refer to service-specific error code 1".
I installed Oracle 11g on Windows 7 and created my 1st database instance (oracleInstance1) successfully with a listener and service configured. I could access this database using DBconsole URL: https://hostname:1158/em.
I see the services started for:
OracleDBConsoleOracleInstance1
OracleOraDb11g_home1TNSListener
OracleServiceOracleInstance1
Next, I created a second database instance (oracleInstance2) and have configured a new service for this database. I am using the same listener as I intend to use one database instance at any point of time.
However, I got this warning message during configuration:
"Enterprise manager configuration succeeded with the following warning - Error starting Database Control. Please execute the following command(s).
1. Set the environment variable ORACLE_UNQNAME to Database unique name.
2. C:\Oracle\product\11.2.0\dbhome_1\bin\emctl.bat start dbconsole"
To start the new database console, I stopped the previously running DBConsole, OracleDBConsoleOracle1 and started the new DBConsole OracleDBConsoleOracle2 and get the above error.
When I try to start dbconsole manually using "emctl dbconsole start", it starts OracleDBConsoleOracle1 instead.
I changed environment variables ORACLE_SID=oracle2 and ORACLE_UNQNAME=oracle2
What am I missing here. Please help!
Thank you.

Thank you.Just to take a side road ...
"I am using the same listener as I intend to use one database instance at any point of time. "
Doesn't' matter if you use one instance or 100. The listener was DESIGNED to service multiple instances of multiple versions running from multiple homes. It is nothing but a connection broker. A telephone switchboard, if you will. All you need is a single listener, with the default name of LISTENER, running on the default port of 1521. It will handle all the database instances you care to throw at it. More instances than anyone in their right mind would ever put on a single server. Your server will run out of capacity to host additional instances before the listener runs out of capacity to service them. Especially since your 'server' is really just a toy in the Oracle world.

Creating a new database in Oracle Database 10g...

I have downloaded a copy of Oracle Database 10g Express Edition from Oracle's website. I am using Windows XP. I am trying to create an Oracle database that I can connect to from Access 2003 via ODBC.
1. How do I create a new database? I can see options to create tables, views, etc. but not a database.
2. I have created a System DSN connection in the ODBC Data Source Administrator for the Oracle ODBC driver. Once I create a database in Oracle, how do I actually establish a connection to it from Access? The ODBC code to connect is there, but when I run it, I get an error.
Any help would be appreciated. Thanks.

1. How do I create a new database? I can see options to create tables, views, etc. but not a database.If you can see those options then you are already connected to the database. You probably want to create a user, not a database (are you by chance coming from SQL Server?)
driver={OracleDriver};Dbq=TESTDBQ;Uid=Administrator;Pwd=;You would replace "Administrator" with the name of the user you created in the database.
