Is schema and database of sqlserver is same.

Hi !
1) i have 10 database in sqlserver 2005, when i made them in oracle xe,
i made user and a connection so it made a schema asociatted with user which has my tables and other objects of one databse of sqlserver.
so i had to made 10 users and connection, so i wanted to know wethere it is right way of doing it?
2) if shemas in oracle is databases of sqlserver, then when we backup it backs up all schem in oracle or there is a way to backup single shema?
3) if backup of oracle backs up all oracle schema, then is there any way to restore only one schema?
yours sincerely.

Well, I'd rather not try to translate the terms directly across. Just think database != database (and so on with respective rdbms implementation).
If you must, a 'database' (file/file group level) in mssql server db is somewhat similar to a 'tablespace' in Oracle.
Your mssql db database also has a schema structure, somewhat similar to Oracle's schema structure. One difference is that Oracle has a closer relationship between user and schema, where as in mssql db there is a division between users and schemas and you define how they should relate.
1) Well, in Oracle you have 1 to 1 relationship and user implies a schema (however it may be empty). So yes if you have 10 schemas you would need at least 10 users in Oracle, since you can't have a "user-less schema".
2) Simple way is to do a schema export, creating an export dump file (which is sometimes referred to as a logical backup).
3) This dump may then be used to import the schema, in the same or different db. Tools for export and import are expdp and impdp.
If you have a real/physical backup (of database files) then you could get that db up and running on a separate host and then export specific schema from there.
Please read up on the Oracle Concepts guide and the 2-day DBA guide, at least. A couple of chapters from Backup and Recovery guide would probably also be agood idea. See Oracle Documentation library for these and more Database books.

Difference Between Database Schema and Database User Account ??

First i would like to know what an Oracle Database schema exactly is ?
And what is it for and also What is it's use ?
Later the exact "Difference Between Database Schema and Database User Account".
I googled about it but i'm unable to find out it's The difference,
Please try to explain in a simple manner........
Thank you very Much in Advance..........

Greate example. but i would like add one more point..
a user is a schema and schema is a user. but when this applies to the user that he become a schema, only if he has got some objects. so we can say while creating the user which dosent contain any objects called simple user account but afterwords when he has got an objects then we can say its a schema as the above user has shown you through the exampleIt is just word-play. There is nothing in like a 'status' indicator to say "USER_A is just a user but USER_B has become a schema". Many people use the terms "user" and "schema" interchangeably, and some very good DBAs will insist this is correct. I don't disagree with them even though I usually try to make the distinction.
In a typical application, all of the objects (tables, procedures, etc) that implement the app will be owned by a "application schema owner" - a user which exists for the sole purpose of owning the schema. Said user will have no privileges at all .. especially not CREATE SESSION. Except for possible maintenance activity no one ever actually connects as this user. User accounts are then given to actual humans who connect with their own accounts. The accounts have the necessary system and object privileges granted to them - via a role. One could also create a special account (let's call it APP_ADMIN) that is used for maintenance and batch operations within the application.

Can I install OBIEE 11g and Database 11g on the same machine?

Hi experts
i have some confusion...
i have oracle database 11g on one of my server.
i want to install OBIEE 11g on that same machine...
i just want to be assure that will it cause any problem or conflict..
because i set ORACLE_HOMe=/home/oracle/app/oracle/product/11.2.0/dbhome_1
and i have to set ORACLE_HOME for OBIEE also....
Please let me know what how to give...and is there any other way
Thanks
Abhishek Anand

Hi Abhishek,
You can install or mount both DB and OBIEE on same machine, but check out the disk space and memory needed should be more to accomodate both.

Installing OAS 10.1.3 and Database 10.2 on same host

I am trying to install 10g R2 and OAS 10.1.3 on same host(linux 2.6.9.-11.ELS). Database installation went fine but OAS is not coming up. Netstat shows all the ports are used. I followed all the instructions for Database and OAS. Is this a 2 tier configuration? Where can i find the OAS system error logs?
Thanks in advance.

Hi,
I've a couple of questions for U;
Which kind of installation of the IAS u did (Mid or Infra & mid)?.
Did U install the IAS on a different file system than the DB?
Ok. U 've a different places for the IAS log files, most important thing is that
under /opmn/logs.
To see the status of your ias process
just login as ias owner with the right environement variables
on the prompt type in
#opmntctl status
if some of your processes 're not alive, U can start it as following:
# opmnctl startproc process-type= (process-type)
U can stop & start all your opmn processes by type
# opmnctl stopall of startall
To start iasconsole
# emctl start iasconsole
've a nice day

Data distribution scheme and database fragmentation

Hi all,
I'm working on a scenario (University) involving the fragmentation of a central database. A company has regional offices i.e. (England, Wales, Scotland) and each regional office has differing combinations of business areas. They currently have one central database in their head office and my task is to "design a data distribution scheme". By scheme does this mean something like horizontal / vertical fragmentation? Also can somebody point me to an Oracle specific example of creating a fragmented table? I've tried to search online and have found the "partition by" keyword but not much else except for database linking - but I'm thinking this is more concerned with querying than actually creating the fragments.
Many thanks for your time

>
Partitioning is what the tutor meant by "fragmentation". So if there is a current central database and I have created new databases for each regional office I could run something like the below statement on the regional databases to create a bespoke version of the employee table filtered by data relevant to them? This is all theoretical and we don't have to develop the database, I just want to get the syntax correct - Thanks!
>
There you go talking about 'new databases' again. You said your original task was this
>
my task is to "design a data distribution scheme".
>
Is the task to give the regions access to their own data in the ONE central DB? Or to actually create a new DB for each region that contains ONLY that regions data?
So are we talking ACCESS to a central DB by region? Or are we talking replication of the entire central DB to multiple regions?
Your example table is partitioned by region. But if each region has their own DB why would you put data for other regions in it?
If you are wanting each region to have access to their own data in the central DB then you could partition the central DB tables like your example:
CREATE TABLE employees (
id INT NOT NULL,
fname VARCHAR(30),
lname VARCHAR(30),
hired DATE NOT NULL DEFAULT '1970-01-01',
separated DATE NOT NULL DEFAULT '9999-12-31',
job_code INT,
store_id INT
PARTITION BY LIST(region_id) (
PARTITION Wales VALUES IN (2)
); But if you are creating a regional DB that includes data only for that region there is no need to partition it.

Database compare script to sync schema and data

1. I have database-1
2. I have database-2
3. database-1 and database-2 are in same oracle 10g server and are same in schema as well as data
4. All operations will be done with database-1 through my application
5. At the end of the day i need a script which is to be run in the database-2 to have database-1 and database-2
alike ie., both schema and Data should be same
Please anyone suggest me the best solution to get the above script
This script is to be transfered to some other location in our scenario
Thanks in advance

Hi Sybrand Bakker,
I tried streams for the replication purpose as per your suggesion, till Iam unable make it work , i dont find a step by step document which will make it possible without error.
One more thing , i need the streams work without Database link, ie., source database is not connected directly to destination database. I need to create streams and transfer the stream as a file through FTP.I need to download stream file in remote location and then apply the streams to destination database and after this source and destination database should be same in data and schema.
Please suggest me a solution to go abt this scenario. We are in critical stage to make it happen...
thanking you in advance
with regards
vivek

Another schema and/or database for a form

Hello.
What if i have a form and I want to change the schema and/or database name for the form? Is that possible? It want to make a form on data from a running production database. But testing is not very nice in a roduction database. So i want to build and test in my own schema and database. Then, when it all works, I want to change it to the running database.
Is that in any way possible with a form from Portal?

A form resides in an Application.
You can not change the Schema on which the application is based on.
What you will need to do is:
App1 -- Based on Schema1 -- Your production Build
App2 -- Based on Schema2 -- Your testing build
Form1 -- Resides here (In App2)
You will have to copy "Form1" to App1. In that case it will be transfered in Schema1
One more way will be:
Export the application
Delete the application
While Importing change the application Schema of the Application.
(Don't forget to take the backup of database before you do this as if anything goes wrong while
doing the above then you can always revert back)
Thanx,
Chetan.

Target Schema and Runtime Instance of Oracle Database

I am new to OWB and starting to understand its architecture.
Does the Runtime Access User, Runtime Repository Schema and Target Schema (discussed a the Runtime Instance) need to be installed on every database that will be a target? For example, if I have a data warehouse and two data marts, with I have three installations?

Hi,
You need to run the OWB Runtime Assistent for every target schema, that is correct (it will add the auditing stuff that enables you to monitor what's happening deployment and execution wise).
Whether you need to create a Runtime Repository and its accompanying Runtime Access User(s) for each and every target I'm not sure.
If your target schema's are on the same instance I'd say that you can use as few or many Runtime Repositories as you wish.
When on different instances I think it's necessary to create them.
Hopefully other forum-attendees can add some more if they have definite answers.
Cheers, Patrick

VLD-1124: Schema and/or Database link physical configuration parameters

Hi!
The warning message:
VLD-1124: Schema and/or Database link physical configuration parameters should not be set for Table1.
Is it possible to eliminate this warning message ? Anyway , Thanks for your response!
Bye!

Hi guys,
I am facing a strange problem. The code generated for my mapping has NOT used the dblinks. My OWB version is 10.1.0.4
This is my problem in brief.
I have installed OWB newly and started to do a sample task. I created a very simple one to one table population mapping from source to the target schema. Both are in the same database.
When i generated the code for the mapping, it gave a warning 'VLD-2771: System privileges may not allow extraction from source EMP'.
When i checked the code which was generated, i couldnot see any dblinks associated with my source table( which seems strange)
CURSOR "INGRP_c" IS
SELECT
"EMP_SRC_TRG_CONN"."EMPNO" "EMPNO",
"EMP_SRC_TRG_CONN"."ENAME" "ENAME",
"EMP_SRC_TRG_CONN"."JOB" "JOB",
"EMP_SRC_TRG_CONN"."MGR" "MGR",
"EMP_SRC_TRG_CONN"."HIREDATE" "HIREDATE",
"EMP_SRC_TRG_CONN"."SAL" "SAL",
"EMP_SRC_TRG_CONN"."COMM" "COMM",
"DEPT_SRC_TRG_CONN"."DEPTNO" "DEPTNO_1",
"DEPT_SRC_TRG_CONN"."DNAME" "DNAME",
"EMP_SRC_TRG_CONN"."DEPTNO" "DEPTNO",
"DEPT_SRC_TRG_CONN"."LOC" "LOC"
FROM "SCOTT"."EMP" "EMP_SRC_TRG_CONN" ;
In brief this is the process i have done.
Source schema : SCOTT & Target schema : TRG_SCHEMA
1) I have created source (for SCOTT) and target(for TRG_SCHEMA) modules.
2) I have also created DBLinks, Locations and Connector from source to the target locations.
3) I registered both the source location and target locations.
4) Validated, Generated and Deployed the Connector from source to the target.
I was unable to trace the error. Did i miss anything in the configuration? or during the installation of OWB.
Though it is a very old post, i hope someone can help me out here.
Thanks in Advance,
Sri

Migrating and Backing up Schemas (complex database structures)

Hey guys, I need to figure out a way to back up and also migrate our Oracle database from our production schema to the dev schema and the other way around.
We have bunch of config tables that drive how systems on our platform run, and when setting up new systems or doing maintenance, we need to update our config tables. We want to be able to work on the dev schemas and after setting up a system/feature, we want to be able to migrate all those configs to the dev schemas.
I thought of running a procedure where we give the ID of the system (from the main table) and i would go through all the tables and select nvl(..) and if it doesn't exist, i would insert into, and if it does exist then i just run an update on that row.
This code will get very messy and complicated especially since the whole config schema is very complex and it might be hard to handle all the keys properly.
Another option i was looking at was triggers, so when setting up a new system, there would be a log of all the statements we ran while setting up/editing a system, then we would run it on our production schema.
I'm on a coop term, and have only been working with databases for 6 months, so i don't know that much and any information/advice would be greatly appericiated.

Yes i guess it might not be migration, it's just what the project is called around here :)
Regardless, yes the intiial idea was replication, should create all the keys from stratch when creating the entries in the production schema but we abondened the idea and we'll be using the production sequences for creating the primary keys in the development, and just make an exact copy back and forth...
Do you think i can just start from the top of the hierarchy (even though not clearly defined, so hierarchy might not be very straight forward) and loop through that table, insert or update, then move one level down, copy and update and so on?
Also is there any sources where i can get more information regarding triggers

Can Portal 3.0 and 8i/9i Database Software exist on same Machine?

Our current setup at work is webdb 2.1 and Oracle EE 8.0.5 residing on ONE physical server.
(Sun Solaris)I need to upgrade the Software to Oracle EE 8.1.7 and Portal 3.0. We do not run Webdb as part of an internet or intranet site(These are controled by other departments)We use these products so a small number of users (9-30) can easily access a data warehouse via a browser. I will never get the funding for a 2nd Physical machine to act as as application server. I am hoping I am confused but can Portal 3.0 and 8i/9i Datbase software be installed on the same physical machine? I was led to believe that 9i Application Server Software can not be installed on the same machine as the 8i/9i
database.Why do I need application server software or the 9iAS http listener when Oracle 8.1.7 comes with an inbuilt http listener?
If we have to have a 2nd physical machine,
management will pull the plug on Oracle and will go with another vedor solution. I don't want to loose my Oracle SQL skills, can someone please help!

I've installed Portal 3 (production) and database 8.1.7 on one machine running Windows 2000 and 99% works fine.
The procedure is:
1) Install the database from operating user X in Oracle-home A
2) Turn off the http-listener for the database.
3) Install iAS from os-user Y in Oracle-home B.
If you do not use separate users or use database 8.1.6 or earlier, you get problems with the java-patchs and libraries.
By the way - it is NOT possible to install a development environment (Designer 6/6i, Developer 6i, Discoverer 3.1) on that same machine. Cause is that ias9i installs Developer 6i patch 2 (runtime) and that version doesn't operate against the latest available development patches. So, I think in your case you have to install the development software on the clientmachines.

Can't i use xml schema and oledb data connection at the same time?

Hello to all and thanks in advance.I use xml schema and oledb data connection at the same time and the problem is that when I try to export the xml, the outcome is not what i expect.Without the oledb connection everything is ok (just the schema) and the xml complies with the schema.
Can't i have both schema and oledb and the exported xml be as i want it?

You can use both at the same time, but not gor Internet access if that's what you're asking.
Now there is a thing called Link Aggregation, which combines a number of interfaces for speed/redundancy, but it really only works locally, and then only with ALL special equipment in the route, and most likely OSX Server involved.
Sorry.

New User Database schema and table name

When i create a new user in Oracle Webcenter Spaces 11g, I am not able to get the name of the database schema and table, where it is stored. Any insight on this will be very helpful.

WebCenter (and WebCenter spaces) uses an 'identity store' instead of database schema for storing user information - in an 'out of the box' installation, users are maintained through an embedded WebLogic LDAP store.
See the Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter, p. 34-2.
At the end of section 34.4.1:
WebCenter Spaces supports self-registration. When new WebCenter users
self-register, they create their own login and password and a new user account is
created in the identity store. See also, Section 34.4, "Allowing Self-Registration".

Using TOAD and SQL Developer to compare db objects in schemas in databases

Hi All,
My primary objective was to compare objects in schemas in two different databases and find out the differences,
Execute DDL's in the database where objects are missing and syn schemas in two different databases.
So I need to compare schemas in databases. Which tool would be helpful and will be user friendly to make a comparison of database objects existing in schemas in two different databases.
I'd like to see if I can get a list of pro and cons between Toad and SQL Developer for comparing schemas pros and cons.
Could you please also help me on navigation in SQL Developer to compare schemas.
Connect to Source
Connect to Target
Compare schemas with different object types
Find out differences
Generate DDL's for the missing objects or for the objects in difference report
Run them in missing instace(Source/Target)
Make sure both are in sync.
Thanks All

Hi,
Most dba type tools have this kind of functionality - personally i use plsqldeveloper but this is very similar to most other tools on the market. SQL Developer seems to rely on you needing the change management pack licence which you likely dont have and would be quite a large cost to roll out.
I'd compare plsqldeveloper/toad/sqlnavigator etc and maybe the tools from redgate which look pretty good though i haven't used them.
Regards,
Harry
