Oracle Database schema

Can someone suggest me tools to view and print database schema (along with links showing relationships) for Oracle DB.
I am preferably looking for free tools.
I did search on google, couldn't find anything useful.
thanks for your time and help.

Couldn't find proper documentation to use it.
Any other suggestions. I need schema diagram with all tables and thier relationship links.
Thanks.

Can't access tables in other Oracle database schemas

Hi. We got our Oracle database admin to install APEX in our Oracle database. She created a login and schema for my Oracle database user so that I could work with APEX a little. Here's the information on the version of APEX we have installed:
Database Version Information
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
PL/SQL Release 11.2.0.2.0 - Production
CORE 11.2.0.2.0 Production
TNS for IBM/AIX RISC System/6000: Version 11.2.0.2.0 - Production
NLSRTL Version 11.2.0.2.0 - Production
I've found that my user is only able to access Oracle tables within my own Oracle database schema. Most of our main tables are in 3 other schemas and I'd need access to all tables in all these schemas. Right now whenever I encounter a drop list of values for Schema, only by own schema is available in the list of values.
Is there something our Admin can do to make these tables in other schemas available to my user account?

Sharpe,
This documentation should point you in the right direction. It will show you how to add multiple schemas to a workspace.

Life can be so easy when you aren't lazy. You don't waste time asking to be spoon fed by others if you can do something yourself in 2 seconds.

How to create an XML Oracle database schema

Hello, I would like to generate an XML file that contains the schema of my Oracle database so that I can reference one file for column names and table names. I do not need any data from the tables, just the basic layout: e.g. table names, their respective column names.
Obviously, I would like the ability to generate this file each time we make changes to our DB, so its generation will be an ongoing process.
My question is, what is the best tool for this? Or the most widely accepted? Can anyone help with this?

To get database metadata as XML use Oracle Web RowSet.
//Import the oracle.jdbc.rowset package classes.
import oracle.jdbc.rowset.*;
//Import the RowSetMetaDataImpl class.
import javax.sql.rowset.RowSetMetaDataImpl;
//Create a OracleWebRowSet class.
OracleWebRowSet webRowSet=new OracleWebRowSet();
/*Set the datasource name to obtain a JDBC connection with the database. The datasource name is configured in the data-sources.xml file. */
webRowSet.setDataSourceName("jdbc/OracleDataSource");
//Set the SQL query command for the OracleWebRowSet class object.
webRowSet.setCommand(selectQuery);
selectQuery is a SQL command variable which is input from a JSP.
//Set the username and password to obtain a JDBC connection.
webRowSet.setUsername("OE");
webRowSet.setPassword("<password>");
//Set the read only, fetch size and max rows attributes of the OracleWebRowSet object.
webRowSet.setReadOnly(false);
webRowSet.setFetchSize(5);
webRowSet.setMaxRows(3);
//Run the SQL command specified in the setCommand() method.
webRowSet.execute();
/*A Web RowSet gets created consisting of the data retrieved from the database table with the SQL query. Generate an XML document from the WebRowSet.*/
OutputStreamWriter output=new OutputStreamWriter( new
FileOutputStream(new File("c:/output/output.xml")));
webRowSet.writeXml(output);

How to compare two oracle database schemas

hi all,
i want to compare and find out differences between two oracle databases. The comparison should be made on between table definition,table data,primary and foreign keys, packages and functions.
Is there any management console or tool embedded in the oracle enterprise manger?
it is really appreciate if anyone can point me towards wright direction asap.

Hi ,
This script would help u a lot in comparing 2 schemas and generate a report on them.
Script:
This script will compare two Oracle schemas and generate a report of
discrepencies and this script has been used against Oracle 7.3.4, 8.0.5,
REM and 8.1.7 databases, but it should also work with other versions.
REM
REM Please note that the following schema object types and attributes are
REM not compared by this script at this time:
REM
REM cluster definitions
REM comments on tables and columns
REM nesting, partition, IOT, and temporary attributes of tables
REM snapshots/materialized views, logs, and refresh groups
REM foreign function libraries
REM object types
REM operators
REM indextypes
REM dimensions
REM auditing information
REM new schema attributes added for Oracle 9i

Can I get the oracle database schema in xml like the original ones

Working with Migration Workbench I've found that uses an XML
with the schema of the original database. I'm asking if I can
get the equivalent XML for the oracle model.
I need a quickly way of get in XML the structure (not data) of
my oracle databases.
Any idea?

Ok, it is unclear on what is happening here.
Are you saying that when the webclient gets the data that it is not honoring the quote characters? Or the processing of the data buffer is causing issues?
This is what I see the of your example text which is trying to be parse out:
<a onmouseover="EnterContent('ToolTip','תווית על בגד: ’’תן לאישה לכבס. זה תפקידה’’','כתב: Spook בתאריך: 08.03.15 שעה: 22:11 מחאת טוויטר קמה בעקבות תוויות שוביניסטיות שהדפיסה חברת אופנה באינדונזיה לפיהן תפקיד הכביסה מוטל על האישה. החברה התנצלה אך כנראה רק עשתה רק יותר נזק לע...'); Activate();">";
It appears to me that the escapes `’` does not have matching `“` anywhere within the tooltip. So it appears that the page properly places left quotes in when processing the page, but the raw html has broken text.
Hence a garbage in, garbage out situation.

Slow database/schema - network OK

We have an arrangement at a users site that has an IIS web server connected to an Oracle database Schema. The ping (<1ms) and trace route between them are very healthy. The web server is OK too. Yet when the server reads and writes data to the database the process is very slow.
We’ve even taken the web server out of the equation and got the DBA to run a small script that inserts and deletes data and captures some timings. The result is the read and write (Select, update and delete) take at least 200% longer than in most other environments we ran the same test in. All in all the bottle neck is the Oracle 9 server.
The database server itself is supposed to be very powerful. Any suggestions?

I don't think there is anything wrong with the Actual SQL of the application, under normal circumstances it is quite efficient, we have it running on several servers with no problems. The test script was devised to prove it wasn't the SQL of the application or the application server itself. It creates a table with two columns and using loops inserts, updates and deletes the data. The test table is index on the ID column.
In using this test script on other servers the time it took to complete the operations was very quick except for this one Oracle 9 server. We understand the server is hosting serveral Oracle databases each containing several users and schemas also in the afternoons the time the operation takes can be even longer pointing towards some sort of load management issue.

Configuring New Oracle Database with HFM Shared Services

Hi,
We have upgrated the oracle database to new version 11g. We are using HFM 11.1.1.3 version. When I tried to configure the new oracle database with existing HFM Shared Services, the EPM Configurator hangs. Please could you clarify the below few questions before start configuring the database.
1. Do we want edit any properties or configuration files before starting the EPM Configurator?
2. If we want to edit the reg.properties file, what is the password denotes in reg.properties file(Below is the structure of the reg.properties file)? Whether I need to give Oracle database schema password?
jdbc.url=jdbc\:hyperion\:oracle\://xxxxx;
password=?
jdbc.driver=hyperion.jdbc.oracle.OracleDriver
local.value=####
username=schemaname
Thanks,
Aravindh K

Is it a new database server you are trying to configure? As if it was just upgraded then you shouldnt need to do anything.
If it is a new database server then have a read of the following doc in Oracle Support - "How To Change Shared Services Database Repository in EPM 11 [ID 976279.1]"

ER DIAGRAM FROM ORACLE DATABASE

Hi, I have an oracle database with diferent schemas. I have'nt got the data model of that schemes, and I want to get the data model and the ER diagram. I'm looking for a free tool for it get in a graphical model the er diagram.
Anyone can help me?
PD: I don't know if this question is correct in this thread but I didn't know which is the correct thread.

George Milliken wrote:
Right.....but then they won't be in the Oracle Database will they? The original poster asked to ERD his Oracle Database Schema, which is not likely to be on the client.....right?Strictly speaking, yes. But people who ask these kinds of question are usually looking for something more encompassing, trying to understand all of their data relationships without stopping to think that in a lot of (poorly designed) systems, those relationships are not defined within the database. I've worked with some VERY large manufacturing systems that had no RI at all -- it was all defined in the application code. As far as the database was concerned, there were no entity relationships to diagram.

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.

How many users/ schemas can we create in an oracle database?

How many users can we create in an oracle database? Or how many users can oracle handle?
Problem-
I have to store information of ontologies (I will use countries instead) in db.
I have to store information regarding countries.
I have 13 tables in all to maintain for each country.
Now there are two approaches:
1) keep only 13 tables. Have an extra column in each table to indicate that a particular
row stores information for which country.
2) create a new user/ schema for each country. So we can get rid of the extra column
needed in 1st approach.
I have used the second approach. This is because number of entries in each table for a
given country will be large.
So initially when the s/w is installed I create a central-user. Each time data for new
country has to be entered central-user creates a user/ schema, and creates tables for
this user/ schema. The central user can access the tables of all the countries by
country_name.table_name. By this approach I believe searching would be easy.
If there is any flaw in my approach kindly mention it.
Thank you

There is no (practical at least) limit to the number of users & schemas you can have in Oracle.
Your approach, however, is not going to scale nearly as well as the first option you outlined (adding a column). You are going to end up caching every possible variation of the various queries you're going to be executing because you will be referring to so many different tables, which is going to mean that you are doing a lot more work to parsing statements and generally churning through the shared pool. If you create enough users, you're liable to start hitting ORA-04030 errors because your shared pool is so fragmented.
Additionally, you're likely going to end up with a whole lot of dynamically generated SQL to accommodate new schemas getting added over time which is going to cause you even more pain. Figuring out dynamically what table to join in is a heck of a lot more difficult for the programmer to write and for the database to handle than simply passing in a different country code.
If you're concerned about having too much data, you can have your cake and eat it to by adding the country column and partitioning the tables based on country.
Justin
One other item I forgot to mention is maintainability. Having dozens or hundreds of "identical" schemas makes maintenance a huge pain because something like adding a new column now requires dozens or hundreds of separate DDL statements. You're almost guaranteed that some schema isn't going to be in sync-- it's going to miss a column or miss an index, etc.

Different schemas in the same Oracle database

Both my source and target tables are in the same physical Oracle database (different schemas).
I can use the LKM Oracle to Oracle (DBLINK) knowledge module to load data but this requires setting up a dblink between the two schemas. Given that I can set this up so that the target schema has select etc permissions on the source schema, I can't help feeling that there is a simpler (more efficient?) way of doing this.
One of the steps in the LKM is 'Create Synonym on Target' which does the following
create synonym <%=snpRef.getTable("L", "COLL_NAME", "W")%>
for <%=snpRef.getTable("R", "COLL_NAME", "W")%>
This creates an Oracle synonym that includes a dblink (e.g create synonym s1 for s2@dblink). I can't help feeling that if I could change this so that it doesn't include the '@dblink' part then I could solve the problem and just create a synonym in the target schema that points directly to the source (e.g create synonymn s1 for source.s2). This should then mean that all the rest of the load etc process could run just the same.
I'm sure that there must be a way of doing this, but I can't figure out how to do it using the substitution methods API.
Any ideas how I do this?
Thanks,
Chris

Chris,
for sure when you define a Data Server you have to specify user which have appropriate access to both source and target schemas.
Then you can create 2 schemas in one Data Server and ODI will use queries like
insert into target_schema.tab_name
select ... from source_schema.tab1 ...
Loading KM will not be used in that case at all therefore data flow will work MUCH faster.
