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.)

How we create new data base in oracle 10g express edition

hello every body.. i student of B tech n new user of oracle so please help me how we creat new data base in oracle 10g express edition

Hello, Oracle XE can not create more than one instance, the other editions yes, but like other editions XE allows you to create database schemas, schemas logically grouped objects like tables, views, indexes created by a user. By creating an Oracle user is associated with a schema of the same name.
Using SYS or system accounts for creating user accounts.
Syntax to create a user:
create user Your_user
IDENTIFIED BY password
default tablespace users;
grant connect, resources to your_user;

How can I create a new database?

Hi,
can anyone tell me the steps I have to do if I want to create a new database? Can I perform this operation from the console of the Enterprise Manager or from the DBA studio?
Thank you.

You can use DBAssist to create Database of your own desire. No need to go anywhere if u r working on 8i.
If this sounds good to u then steps can be followed.

I installed "Oracle Database 10g Express Edition".
After install I tried to "Go To Database Home Page" and received a "Page not found" error.
If I run SQLPLUS and ...:
connect / as sysdba
shutdown immediate
startup
I get

And I can not find any control files on my PC.
Can I create one?

Yes. This is correct. There is no control file. In fact, there is nothing in C:\OracleXE\oradata\XE. It appears that the install did not create a database, so I figured I'd try to create one myself
but did not haev any success. Should the install have created a database? I did install the same product on a laptop and it seemed to work fine. The problem I ran into was that it does not have
enough memory to be useful, only 512 Meg. So I decided to install it on my desktop PC with 3 Gig. This is where I am having the problem. I tried a re-install but still no database was created.

How to Create A new Database in the oracle 10g XE

Hi there 785434,
(This is a generic SQL question relating to Database Triggers, please post future questions of this type into the relevant forum area.)
Moderator, please move this if able
I use Before Update and Before Delete Triggers to record a 'snapshot' of the row being changed in my applications.
Example:
CREATE TABLE TEST
DATA VARCHAR2(64 CHAR),
CREATING_USERID VARCHAR2(20 CHAR) DEFAULT user NOT NULL,
CREATED_DATE DATE NOT NULL,
CHANGED_BY_USERID VARCHAR2(20 CHAR),
CHANGED_DATE DATE
LOGGING
STORAGE
(MAXEXTENTS UNLIMITED);
CREATE TABLE TEST_HISTORY
DATA VARCHAR2(64 CHAR),
CREATING_USERID VARCHAR2(20 CHAR) DEFAULT user NOT NULL,
CREATED_DATE DATE NOT NULL,
CHANGED_BY_USERID VARCHAR2(20 CHAR),
CHANGED_DATE DATE,
CHANGE_DESCRIPTION
NOLOGGING
STORAGE
(MAXEXTENTS UNLIMITED);
CREATE OR REPLACE TRIGGER TRG_BU_TEST
BEFORE UPDATE ON TEST FOR EACH ROW
BEGIN
INSERT /*+ append */ INTO TEST_HISTORY
(DATA, CREATING_USERID, CREATED_DATE, CHANGED_BY_USERID, CHANGED_DATE, CHANGE_DESCRIPTION)
VALUES
(:old.DATA, :old.CREATING_USERID, :old.CREATED_DATE, USER, SYSDATE, 'UPDATE');
END;
CREATE OR REPLACE TRIGGER TRG_BD_TEST
BEFORE DELETE ON TEST FOR EACH ROW
BEGIN
INSERT /*+ append */ INTO TEST_HISTORY
(DATA, CREATING_USERID, CREATED_DATE, CHANGED_BY_USERID, CHANGED_DATE, CHANGE_DESCRIPTION)
VALUES
(:old.DATA, :old.CREATING_USERID, :old.CREATED_DATE, USER, SYSDATE, 'DELETE');
END;
Using triggers like this will record who made an update or delete to the database and record the row before it was changed.
Note that this method might not be suitable for very high transaction rates.
You will need to 'clear' these history tables as part of routine maintenance.
Hope that this Helps.
Ronald.

How can i create a new instance on unix

Hi,
How can i create a new instance(instance only) on UNIX and how can i mount my database with this new instance.

If you simply create a pfile and startup nomount with it, then -in theory- you have an instance running ( this method is used e.g. for restoring a rman backup )
2) You can't. Database files are bound to a certain instance. What you can do is recreate an instance with e.g. a different name, using the scripts generated by a 'alter database backup controlfile to trace;' command

How can i create a new and tableless database using database configuration

How can i create a new and tableless database using database configuration

How can i create a new and tableless database using database configuration
Just don't install the sample schemas. See the installation guide
http://docs.oracle.com/cd/E11882_01/server.112/e10831/installation.htm
Using the Database Configuration Assistant
When you install Oracle Database with the Oracle Universal Installer, the sample schemas are installed by default if you select the Basic Installation option. Selecting the sample schemas option installs all five schemas (HR, OE, PM, IX, and SH) in the database. If you choose not to install the sample schemas at that time, you can add them later by following the instructions in section "Manually Installing Sample Schemas".
Choose a custom install and don't install the sample schemas.
All other schems/tables installed are REQUIRED by Oracle

How can I create a new entry without using LOV for foreign keys.

Referring to TUHRA sample application based on HR database schema. JDeveloper 10.1.3.0.4
How can I create a new employee without using LOV for the foreign key "job_id".
On the first page I would like to choose the job_title from adf read-only table.
After clicking on the "create new employee button" a creation form appears in which the job_id field is set with previous selection.

Hi,
usually the foreign key is only set if the VO you select is dependent from a master. If e.g. you have DepartmentsVO1 that has an EmployeeVO3 as its nested VO, then creating a new instance of employees automatically add the foreign key. If you add EmployeesVO1, which is not dependent to DepartmensVO1, then the foreign key is not set. So if this is the case in THURA (keep in mind that this is not an Oracle demo but a sample used in a book about ADF) then all you need is to take the independent VO when building the new employee form.

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

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
Yogeeraj

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.

How can i create a new user with only read rights ?

How can i create a new user with only read rights ?

You are asking about a Database User I hope.
You can look into the Oracle 8i Documentation and find various privillages listed.
In particular, you may find:
Chapter 27 Privileges, Roles, and Security Policies
an intresting chapter.
You may want to do this with the various tools included with 8i - including the
Oracle DBA Studio - expand the Security node and you can create USERS and ROLES.
Or use SQL*Plus. To create a
user / password named John / Smith, you would login to SQL*Plus as System/manager (or other) and type in:
Create user John identified by Smith;
Grant CONNECT to John;
Grant SELECT ANY TABLE to John;
commit;
There is much more you can do
depending on your needs.
Please read the documentation.

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,
venkat

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.
