Export only database structure

Hi
I want export the database sctructure, without data, Is this possible?, somebody can help me?
Thanks and Regards

You can use export with option rows=n (see http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14215/exp_imp.htm#sthref2348)
or package service DBMS_METADATA.GET_DLL (see http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_metada.htm#sthref4253)

Database Structure Dump into SQL file

I would like to dump the entire structure of my database into an file that will be used later to recreate the same structure. I would like oracle to create almost like a sql file the can be run in another tablespace. I would like to create all the sql commands that would be used to create the tables and sequence generators. Is there a command in oracle that dumps the information?
Thanks,
eric

No there isn't such a command
But You can use export to export only table structure without data and You can see all CREATE statements there
Or you can use Oracle Designer, Visio or maybe another free tool to reverse engineer tables and then generate CREATE scripts
Or You can make Your own script or maybe search for one in internet that creates these DDL statements from data dictionary

Export schema table structure only- no procedures

Hi Friends,

We have more one hundred tables. that needs to be include tables option.
Do you have any simple way to export a schema tables structure without list 120 table's name in exp command?
Edited by: user589812 on Jan 4, 2012 10:19 AMI do not believe you have a choice. One method could be to get a list of all needed tables (SELECT TABLE_NAME FROM USER_TABLES) and create a par file with this list.

How to write export dump commad with no datable data only table structure.

How to write export dump commad with no datable data only table structure will there and command for hole schma.
e.g. export dump command for scott schema and all table within scott schema in it no table data should be exported.

If I understand the question, it sounds like you just need to add the flag "ROWS=N" to your export command (I assume that you're talking about the old export utility, not the Data Pump version).

Thanks.Check the log file, if you haven't got any error, then it's valid
BTW - Why you've taken full export of the database? Why not using RMAN?
See the following video tutorial:

Gathering Entire Database Structure

Hi Geeks,
I want to gather the entire database structure for our client database, which is outside of our country and it is impossible to send the export dump file since so many formalities are there. I need to gather the information, but not through export dump file. I don't need the datas, but only the structure from A-Z.
Is there any possible way to do it.
Kindly help me.
Thanks,
Bang.

Hi,
If i understood your question correctly then can use RMAN if you have the access. invoke "show schema" command to know the structure of your Database; Eg in my case:
C:\Documents and Settings\smuthalagan>set oracle_sid=test
C:\Documents and Settings\smuthalagan>rman
Recovery Manager: Release 10.1.0.2.0 - Production
Copyright (c) 1995, 2004, Oracle. All rights reserved.
RMAN> connect target
connected to target database: TEST (DBID=1915532430)
RMAN> report schema;
using target database controlfile instead of recovery catalog
Report of database schema
File K-bytes Tablespace RB segs Datafile Name
1 460800 SYSTEM *** E:\ORACLE\PRODUCT\10.1.0\ORADATA\TE
ST\SYSTEM01.DBF
2 30720 UNDOTBS1 *** E:\ORACLE\PRODUCT\10.1.0\ORADATA\TE

The database structure has been modified - how to check if it happend?

Hello,
I have a question. How to check if the database structure has been modified? I know that there is shown a messagebox after creating table and adding some fields, but sometimes this message appear after some seconds. The problem is that I want to create table and UDO for this table, and until database structure is not modified I got an error message. If I wait and DB strucuture modifies then UDO is creating correctly.
My question is - does anyone know how to check if database structure has been modified?
Regards,
Hmg

Hi Szymon,
I guess you are stuck up in a kinda scenario, where in, you will be populating a form with values, before the structure modifies, if this is going to be your problem, I can help you out with a work around.
In the beginning of the process, before the creation of the UDO or tables, set a boolean value to false, and once all UDO's and Tables are created, only then, should you make it true and only after the boolean becomes true, you should proceed with populating the values from the screen.
I really ament sure what your problem is, but one of my guys faced this problem, I then, thought even you might have a similar problem.

Use same report with same database structure to different database server.

Hi,
I have standard crystal reports which needs to be copied to another database server.
The origin database has exactly same database structure with the data base in other server.
My only question is how to change the connection of the crystal report file from old database server to new one without affecting the linked tables in the report. Would it be possible?
Note: origin database and new database has same structure, tables and columns but differ in data on it. and both has different server. (MS SQL)
Thanks,

Hi Mark,
Open the report in the CR Designer > select Database option on the top > select Set Datasource location.
The pane on the top shows the current connection. Go ahead and create a new connection to the target database from the pane at the bottom. Once created, highlight one table from the top, highlight the corresponding table from the bottom pane and click Update. Do this for each table.

Automatic Checking of Database Structures

In OSS note 521870 SAP recommends to perform a weekly
check of the Database Structures to verify that the
Maxdb database is not corrupt. Unfortunately this
OSS note only describes the manual procedure to
perform this task:
dbmgui -> Check -> Database Structure
Is there any way to easily schedule this also via dbmcli?
The SAP online documentation contains some interesting
information about integrating the check into the CCMS,
here I can see whether the database structure check
was performed recently, but unfortunately I cannot
schedule it
http://dev.mysql.com/doc/maxdb/en/30/5ada6e596211d4aa83006094b92fad/content.htm
All I can find here is to schedule it via DB13,
but unfortunately my SCM 4.1 system is running on
Oracle and I want to check the liveCache on Maxdb,
so I cannot use DB13 for scheduling the check.

Hello Mark,
Central DBA Planning Calendar ::
In the user menu, choose the Central DBA Planning Calendar
(transaction DB13C).
If it is not already there, add your liveCache to the list of systems.
To do this, choose Configuration ® Add System.
System ID: Enter here the liveCache name that you assigned during the
integration of the liveCache (using MaxDB/liveCache System Overview).
Database: Choose SDB/LVC.
Database Release: Choose the liveCache Version in accordance with the
version notation .
Select No SAP Basis.
Database Server: Enter the name of the liveCache server.
Connection Name: Enter the name of the database connection.
To switch to a local DBA planning calendar, choose Local Calendar and then
select the system for which you want to edit actions.
Please also review the SAP notes 940420, 521870 ( you already know this note ).

Oracle database Structure Size

HI ,
Can any one tell me how to find the size of a oracle database with out data , meaning only the structure meta data only.
Thanks
lbn76

Hi
plese explain Youre question
Do You want to get DDL-statement to recreate objects ?
The space which You allocated for database is reserved and marked on blocks.
Free bloks doesn't belong to a reserve of an empty space of operating system .
I think if You whant to get size of the absolutely empty database
You need to calculate sizes of minimum necessary files in tablespaces SYSTEM, SYSAUX, Redo-files, control files , password- and controlfiles
or shrinking every table to a minimum space, move HWM and then calculate the size that Youre database occupy

Changing database structure

I have to add a tabel a mailalerttext and link that to mailalertypes which is linked to mailalerts. I had some problems with the selectlists, underneath you will find something that will solve that problem I thought, but it may be easier to solve it simpler, but thats apex stuff.
If a default user and default applicationcode would exist, it would be possible to use them in the mailalert table which has following colums:
MAILALERTID,APPLICATIECD,GEBRUIKERID,MAILALERTTYPEID,SENDMAILIND
gebruikerid means userid.
The defaultuser and application code would then be used in the mailalerts table and the column mailalertype would be replaced by mailalerttypecode. These are defined they can't change.
The reason is that if mailalerttext is linked to maillalerts using the mailalertid as the foreign key, then that allows to find the correct text, or select it straightaway by using the mailtextid. All the selects would then be made on the mailalert table.
The numbers used as default are just those that are free, a default user can be filled in like that in te gebruikers table, and a default application code in the apps table.
Only the standard user and the mailalerttypecode are important, the standard applicationcode could be used as an extra check but might not be necessary.
A select could then be made on that applicationcode, that user, that typecode if not found select standarduser and typecode.
Applicationcode is only filled in to stick to the table definitions. To solve a problem with a select list on a page in apex i think this is overkill, as it requires more changes then does the first solution, It means changing tables, dropping columns adding them, changing triggers, changing code in apex pages, a lot of work.
But I was wondering if concerning a database structure, starting from scratch this is something that would be considered good, not so good, bad, something to not do ?
I'm not sure this is the right group, but it isn't strictly apex, and it isn't really sql/plsql either. More database structure.
I'm just beginning, so i'd like to know your opinions and why it would be bad, or possibly good.

I'm still not sure I understand your existing data model properly. The following is my interpretation of what I think your're trying to achieve.
There are four core data tables -
* APPLICATIONS - holds information relating to the programs you administer
* MAIL_TEXT - holds boilerplate text for each type of e-mail (I'm assuming this text can be shared across applications)
* MAIL_TYPES - the different kinds of e-mail alerts which can be sent
* USERS - holds information about the support staff.
I think you need two intersection tables
* APP_MAIL_TYPES - application X uses text Y for e-mails of type Z (candidate key: app id and type id)
* USER_MAIL_REGS - user Joe gets e-mails of type Z from application X (candidate key: app id, type id and user id)
NB If the registration is just done against alert type for all apps, then the USER_MAIL_REGS table shoudl intersect USERS and MAIL_TYPES.

(It's a good idea to use names which convey as much info as possible. I acknowledge the difficulty of doing this in another language). Changing the users' registrations would simply be a matter of inserting or deleting rows from the USER_MAIL_REGS.
If this doesn't help you then I'm afraid you will need to give me more info. Specifically, what tables you have, the role they play and the relationships between them.

Different Database structure migartion

In second version of our software we change the database structure.
Now we need to migrate data from version 1 to version 2 that have different database structure.
Is Streaming or any other oracle feature provides possibility or I should write code by hand?

I sugeest you migrate the tables individaully having in mind the DML and DDL statements
hitting the database from the application end. You need to do a mapping for both the databse.
Do the events from your old application still update the same tables as the new application
You need to really think this out to avoid having complications in your new version.
I dont think stream option is the best at this stage rather export/import of tables would be the best option
then you can think of stream to update your new version at run time.
