How to create new database on Oracle 10g

Hi All,
Can any one tell me how to create new database on oracle 10g.
Thanks in Advance for your help.

again some confusion here.....
u said u need a new database in your first post and now you saying u need a new schema..
one database has many schemas(users)..... ex: scott,sys,system are few of them...
now it depends you need seperate database for test,dev environment - this is in the case u have many schemas under each database and many tables(objects) under each schema.
OR
You just need a separate schema (in same db) for test,dev environment...where in you will have multiple tables in each schema...U need to know the dba credentials of the db to create a new schema.
ideally u need to have different database...You can create one with out sys/system(oracle users) password as these passwords are db dependent.
what you need is access to the any machine where server is installed(can be the same mc where you have your dev db or a diff machine) and that will be the machine where your db will be installed (can do it through database configuration assistance),ofcourse you will need windows authentication for this.
so you login to the same machine or access it from your machine using remote login.
I hope that is clear.Hope i am not listing things that you already know..Just did it coz of confusion between db and schema

Why i can't not create new database in oracle 10g express

why i can't not create new database in oracle 10g express?
should i use oracle 11g standard edition?
thanks

In Oracle a schema is what a 'database' is in Sqlserver.
And if you would have been aware about the limitations of XE, you would have known you can only create *1* (one) database using Oracle XE.
However, probably you don't need a new database at all, and a schema will suffice.

How to create new database in oracle 9i

how to create database in oracle 9i and create all table, trigger and fun/stored procedure in it?
one more thing is that how to assign connection with JSP. i need code if possible.

Roop.IT.Tech wrote:
how to create database in oracle 9i and create all table, trigger and fun/stored procedure in it?Read the docs that come along with the database. This has nothing to do with JDBC.
one more thing is that how to assign connection with JSP. i need code if possible.Create a DAO class which does all the JDBC task. Then create a servlet class which has an instance of the DAO class. In the doGet() or the doPost() do your DAO thing, store the result in the request scope and forward the request to a JSP. In the JSP file use JSTL/EL to display the data to the world.

Hi Rafael
Did you change your shm values in the kernel ? Please check those values in 2.6 Configuring Kernel Parameters
64 bits: http://download.oracle.com/docs/cd/B19306_01/install.102/b15667/pre_install.htm#i1011296
32 bits: http://download.oracle.com/docs/cd/B19306_01/install.102/b15660/pre_install.htm#sthref264
Note that you have to increase : semmni, semmns,shmmni should be multiplied by # of instances, SHMMAX should be set to avail memory
Can you please give us your values from your server please?
Your physical memory :
grep MemTotal /proc/meminfo
And also the result of
ipcs -l
which release of Linux are working with 32 bits or 64 bits ?

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

To create standby database using oracle 10g standared edition

my producation database is oracle 10G standard edition .Can i implement a oracle dataguard or standby database using standard edition licenses.if standby database is possiable in standard edition .what are the steps for creating a standby database using oracle 10g standard edition.

General answer is http://download.oracle.com/docs/cd/B19306_01/license.102/b14199/editions.htm#BABJICBB.
For Data Guard you cannot :
- use instance parameters to automatically send archived redo logs
- use instance parameters to resolve archived redo logs gaps
- create a logical standby
- use SQL statements to do switchover / failover
- use Data Guard Broker.

How to create new database from backup.

Hi !
i have backup of a database, i do not want to restore, i want to create new database from the backup.
i am using oracle 11g xe.
yours sincerely

If the Location of the datafiles is similar to that of source database then you can consider below steps
Create Oracle Service using oradim
set ORACLE_SID=NEWDB
oradim -new -sid NEWDB -intpwd passwordofthesys -startmode M
Connect to the RMAN
rman>rman target /
restore spfile/pfile and control file from backup
rman>restore spfile to pfile '_localtion of the initNEWDB.ora_' from '_location of the SPFILE Backuppiece_';
rman>startup nomount pfile='localtion of the initNEWDB.ora';
rman>restore controlfile from 'file location of the controlfile Backuppiece';
rman>alter database mount;
Catalog the RMAN backuppiece of source database
rman>catalog backuppiece '_location of the rman backuppiece of source database_ ';
resotore & recover database
rman>restore database;
rman>recover database;
open the database with reset logs
rman>alter database open resetlogs;
rman>create spfile from pfile;
rman>shutdown immediate;
rman>startup;
==================
If you have access to source database then you can clone using below rman command:
+rman target _<source database>_ auxiliary _<new database>_+
rman>duplication target database to _<your new database name>_;
==========
If the location of the datafiles and logfiles are different from source database then you need to add db_file_name_convert and log_file_name_convert to the pfile before starting the recovery process.

How to create a new DataBase using Oracle 10g Express Edition???

Hello, I am new to Oracle, I am used to Microsoft SQL Server (Enterprise Manager).
Here in Oracle I do not get how do I create a DataBase, and then create tables on it.
could anyone please explain to me how to do it?

A SQL Server database is roughly equivalent to an Oracle schema.
You should rarely need to create a new database. If you do need to create a database, get a 'for fee' edition of Oracle and use the dbca tool (Database Configuration Assistant) to do that. In fact, you are only allowed to have one XE database on the machine.
However, you can create as many schemas in an existing Oracle database as you need. (One schema, owned by userid SYS, is roughly equal to your 'master catalog'.)
You can create other schemas simply by
1) creating a userid that will own the schema (one designated for maintenance of the schema);
2) grant that userid appropriate privileges, such as 'CREATE TABLE', 'CREATE VIEW' as shown in the SQL Reference manual under the GRANT section;
3) provide that userid with a quota in one or more tablespaces (see the CREATE USER command in the SQL Reference manual);
4) create the objects, such as tabels, views, sequences, stored procs and functions, etc. (as in the SQL Reference manual);
5) create the users who will access the objects, and grant them the CREATE SESSION capability (as in the SQL Reference manual);
6) grant access (select, update, execute, etc.) on the schema objects to these users (as in the SQL Reference manual);
7) if desired, create synonyms on the schema objects so the users do not need to use fully qualified syntax such as "SELECT col FROM schema.table;" (as in the SQL Reference manual).
In case you are interested in looking at the SQL Reference manual, it can be found at http://www.oracle.com/pls/db102/portal.portal_db?selected=1 ;-)

How to Create new database from cold backup files.

Dear Experts,
I have an oracle 10g databae on windows 2003 server.
The database is in Archive log mode and backup strategy is Taking cold backup ever night.
Backup steps:
shut down database.
copy data files, control files, redo logs, archive logs and parameter files to safe location.
Startup.
I have taken a backup at Tuesdaay 1AM and I have archive logs also.
On Wednesday, I want to Create a new database on another server with the available cold backup files and archive logs. I want to recover the database upto 4PM Wednesday. How can I do this.
I am not using control file auto backup or control file backup to trace.
Please help me how can I do this. I am new to oracle database Administration.
--Thanks

The steps :
shut down database.
copy data files, control files, redo logs, archive logs and parameter files to safe location -- you mean the alternate location for the new databaseare correct (except that I would say "alternate location for the new database").
If you do not have controlfile backups, you cannot either OPEN the database or RECOVER the database until and unless you CREATE the Controlfiles. You have to generate a CREATE CONTROLFILE script using a BACKUP CONTROLFILE TO TRACE from the Production serer and create the controlfile on the new server.
BEFORE the Startup, I would use
RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL;The "using backup controlfile" tells Oracle to continue attempting Recovery -- ie doing a RollForward -- till the last archivelog made available to it.
For the Recover command, you then keep applying the ArchiveLogs from the Tuesday 1am ColdBackup upto Wednesday 4pm.
Once you have applied the last ArchiveLog, you do an
ALTER DATABASE OPEN RESETLOGS;Here are my notes of doing a RollForward "Recovery" from a Cold Backup :
http://hemantoracledba.blogspot.com/2007/05/rollforward-from-cold-backup.html
If you are attempting all these steps on a different server from your current Production database, you should be safe.
Once you OPEN the database, you can use CREATE CONTROLFILE or the NID utility to rename the database.
If you are attempting to create the new database on the same server there are many other precautions you have to take and unless you have experience with cloning databases, I would advice you against doing so (only the RMAN DUPLICATE DATABASE command has a safer method of cloning a database).

How to Switch between Databases in ORACLE 10g?

Hi friends, im using ORACLE 10g.
I have two databases namely ORCL and ORCL1.
First I created ORCL and later ORCL1.
Now I am able to see the tables from ORCL1 only.
How can I switch to ORCL?
Thanks in advance.

Hi Aman, I am posting the results below.
From the command prompt:
C:\>SET ORACLE_SID=ORCL
C:\>SQLPLUS
SQL*Plus: Release 10.2.0.1.0 - Production on Tue Feb 19 18:12:24 2008

Oracle Database 10g Release 10.2.0.1.0 - Production
SQL> SELECT * FROM TAB;
TNAME TABTYPE CLUSTERID
DEPT TABLE
EMP TABLE
BONUS TABLE
SALGRADE TABLE
SB4782 TABLE
EDNLN270042 TABLE
CASE_DETAILS TABLE
7 rows selected.
SQL>
And from the SQL*Plus Editor:
SQL> SET ORACLE_SID=ORCL;
SP2-0735: unknown SET option beginning "ORACLE_SID..."
SQL> SELECT * FROM TAB;
TNAME TABTYPE CLUSTERID
DEPT TABLE
EMP TABLE
BONUS TABLE
SALGRADE TABLE
SQL>
So, I am able to get the tables through the command prompt.
But from the SQL*Plus Editor, I am not getting them.
How to get those tables(from ORCL) through the SQL*Plus editor?
Is there any other alternative for setting the ORACLE_SID permanently?
Thank you.
