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
REM
REM Version 02-04-2002

How to install two oracle database on one system

i want to install two oracle databases on single system how it is possible
how i can manager oracle home and is this possible to install two different version of oracle in single home or single system forexample oracle 9 and oracle 8 .
A.R

Hi,
yes, u can have more databases on a single machine and they can be of different versions.
You have to use and initialize the correct ORACLE_HOME to create the DB of the version U use.
For ex, u have 2 homes:
C:\Oracle\Ora817 8i home and C:\Oracle\ora920 9i home
Normally, using OFA, imagine that You want create 2 db, TEST_8I for 8i home and TEST_9I for the 9i home, You shold have:
C:\Oracle\Admin\TEST_8I\<<OFA DIRS>> and C:\Oracle\Oradata\TEST_8I for 8i DB adn C:\Oracle\Admin\TEST_9I\<<OFA DIRS>> and C:\Oracle\Oradata\TEST_9I for the 9i version.
It is important, when You create the DB, that u use the executables of C:\Oracle\Ora817\bin to create 8i db and C:\Oracle\Ora920\bin for the 9i one.
Then U can use the 9i listener to manage both instances
Hope this helps

I'd convert it to xml before, as you can't be sure that two fmb's which are exact the same could look different in a text editor; first form got compiled with forms compiler and the second not => should not differ in functional way but I'm pretty sure that the files itself look diffrerent.

How to compare two xml schemas

Hello guys,
How to compare two xml schemas? is there any tool for that?
Thanksinadvance
kavita//

XML Files may be compared with the oracle.xml.differ.XMLDiff class.
A file consisting of the differences in the xml files gets generated. An XSLT to convert one file to the other also gets generated.

How to compare two databases, without dblink?

Hi all,
I need to compare two differents databases, but I can't create a database link, and for make this task worse, I need to do this using a shell script, because it will run directly in the server.
Anybody can help me?

Hi Justin,
I made the script, and it was working pretty well, but when I was running in the production environment, I get the information that I need to connect with one user and get the ddl to another user, ok, I change the script but now I'm receving the error ORA-31603.
SQL> show user
User is "tstsge3"
SQL> select dbms_metadata.get_ddl('TABLE','INTBD_INS_ACIONAMENTO','TSTINTBD3') ddl from dual;
select dbms_metadata.get_ddl('TABLE','INTBD_INS_ACIONAMENTO','TSTINTBD3') ddl from dual
ORA-31603: object "INTBD_INS_ACIONAMENTO" of type TABLE not found in schema "TSTINTBD3"
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 105
ORA-06512: at "SYS.DBMS_METADATA", line 2805
ORA-06512: at "SYS.DBMS_METADATA", line 4333
ORA-06512: at line 1
SQL> select table_name from all_tables where owner = 'TSTINTBD3' and table_name = 'INTBD_INS_ACIONAMENTO';
TABLE_NAME
INTBD_INS_ACIONAMENTO

I took a look on the internet and metalink, and saw some notes about grant SELECT_CATALOG_ROLE to the connect user, but I can't do this in my customer.
Is ther another solution?

??how to compare two resultsets??

hi all!
i need to find out whether two resultsets contain the same data.
the only way i know how to do it in java is to put them into a while loop and fetch the contents first and then compare the contents.
but is there an easier way to compare resultsets?
does anyone know how to compare two resultsets without extracting the data?
the code example here executes two identical queries on an oracle database, compare and print the resultsets.
public ResultSet getResultset(String query)
ResultSet rs=null;
try { rs=Stmt.executeQuery(query); }
catch(Exception e) { e.printStackTrace(); }
return rs;
public static void main(String[] args) {
ResultSet r1=null;
ResultSet r2=null;
try {
database db = new ddatabase();
r1=db.getResultset("Select 'name' from person");
r2=db.getResultset("Select 'name' from person");
if (r1 == r2) {
System.out.println("ok");
System.out.print(r1);
System.out.println();
System.out.print(r2);
else {
System.out.println("not ok");
System.out.print(r1);
System.out.println();
System.out.print(r2);
jdbc.cleanup();
catch(Exception e) {e.printStackTrace();}
and here is the output:
F:\java rs_compare
not ok
oracle.jdbc.driver.OracleResultSetImpl@4413ee
oracle.jdbc.driver.OracleResultSetImpl@786e64
as you can see the resultsets are different though the data they contain have to be the same.
so the 'if(resultset#1 == resultset#2)' does not work.
thanks for any help
best regards

Don't cross-post.
I'll bet ResultSet implementations don't override equals() to provide "deep equals" behavior, in which case it'll be no different than using "==".
It's a bad idea to compare two ResultSets this way. You'll have to load both into objects or data structures and compare those in a "deep" way.
Besides, the ONLY way two ResultSets could be different, given the same query, would be if there were multiple clients that could write to the table between queries and change the underlying data. If your two queries are sufficiently isolated, I'd say that the same query will return the same ResultSet.

How to compare two stored procedure

I have two oracle database and each database have stored procedure
How to compare two stored procedure?
What is the command to compare the stored procedure?

select line, text
from user_source
where name='....'
minus
select line, text
from user_source
where name='....'
should do nicely.
Or: get the procedure text to a file using dbms_metadata.get_ddl (9i and higher) and run diff (Unix) or fc (Windhoze) on it.
You are a bit scarce on details.
Better still: implement source control.

Two Oracle databases on one AIX Server - Note working, Pls Help

Dear Friends,
I have installed Two SAP systems with Two Oracle Databases on one AIX machine, The Installation of both the systems went fine without any errors, and also i have been able to login to both the systems seperately. (that means i cant start both the systems at a time, its one at a time)
But the problem is of the Oracle Listener, i am not able to start both the systems with single Oracle Listener processes(tnslistener). I tried all the possible scenarios as mentioned in note 98252 but nothing seems to be of any use so far.
the thing is i can start either one of the SAP Systems, But my objective is to start both the SAP Systems with one listener processes (LISTENER) and one listener port (1527)
Or
you can say i am also ready to keep two different listeners for TWO seperate Oracle databases, I tried doing so as per one of the sap notes in which you have to keep different names of listener and different numbers for listener port for second ORACLE database. I tried doing exactly mentioned in the note but yet unsuccessful...
Now i am completely lost as what is to be done since its critical i want you to immediately look into it and suggest me the appropriate solution so that i can set up both of my DEVELOPMENT and QUALITY system running...
To troubleshoot this if you require anything from my side then please feel free to ask me since our functional consultants have to soon start working on the SAP systems.
Regards
Ayush

The note you specified talk about 2 database instances not 2 databases... (I was starting to wonder how you deploy 2 databases), you can have multiple database instances on a DB. The note also give you detailed explanation of the configuration of listener.ora
Now, if this is the case and you have installed 2 instances (not databases) on the same host and configured the listener according to the note, then you should be able to call R3trans -d from both SID's.. if the R3trans fails please post the contents of trans.log here.
the thing is i can start either one of the SAP Systems, But my objective is to start both the SAP Systems with one listener processes (LISTENER) and one listener port (1527)
Then, the configuration of your listener.ora file must be incorrect.
Regards
Juan

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.

How to create a oracle database by java code?

how to create a oracle database by java code?
please give some ways then that way's code

I'm not sure what you mean with "database". Do you mean an Oracle instance or an Oracle user/schema (probably the latter, because that's the equivalent to a MS SQL Database).
Creating an instance is definitely not possible from within Java. To create a new user this should be possible, as this can be done with SQL:
GRANT connect,resource TO <newuser> IDENTIFIED BY <password>;
I'm always cautious with questions like this. In 90% of the cases there is something wrong with the initial design. Creating a database shouldn't be something the application is doing.

Compare two oracle db's

Hi All,
We have two oracle databases and I would like to compare the structure changes in tables, views, procedures, functions etc.
I found a very good tool (i.e. DBDiff for Oracle) but its Demo and only doing first five structure changes.
Does anyone know any other tool or aware of some scripts which solves the above purpose.
Thanks

Create a database link between the two databases. Then run:
SELECT OWNER, OBJECT_NAME, OBJECT_TYPE from DBA_OBJECTS
minus
SELECT OWNER, OBJECT_NAME, OBJECT_TYPE from DBA_OBJECTS@the_db_link_u_created
That will show you the objects that are on the local database that are not on the db_link database. Just reverse the select@ to show results the other way.

Export oracle database schema without data

Hi All,
cany any one tell me how to export oracle database schema without data using exp command not datapump command.

step 1
type exp help=y
step 2

step 3 now run exp ... rows=n

RE: Creation of two oracle database in Single ASM Disk group

IS it possible to create two oracle database in Single ASM Disk group. if it is possible how?.
Giri

All you have to do is to create a tablespace at the most minimumlevel and your db would become a client of the disk group. Other than that, you can migrate your db tothe disk group and it would be then start using the same disk group shared by another database for its use also.

How to compare two Objects !!!!

Hi All,
I know that this question has been asked 100 times till now. But trust me I have checked all of them but couldn`t find answer. Here is my question:
I have an objecs. In that object I am setting (Id,Name,DOJ). Now I want to check whether the object I am trying to save in database already exists or not. If exists then I need to check whether all the setters are same for the two objects. Now can anyone tell me ,how to compare two objects directly without comparing the setters individually.
Thanks in advance.

pavan13 wrote:
That is pretty good idea. However I have a query. Does that code actually compare all the setters in a two beans. I don`t want to check each setter seperately.Well, it's pretty meaningless to talk about "comparing setters", setters are methods, they don't have values to compare. Because equals is inside the class, you can simply compare the fields that get set by the setters. "Properties" is probably a better name.
In principal you could write something that tried to find all relevant fields and compare them, using reflection or bean info stuff. The resulting code would be about 50 times longer and take about 50 times longer to run. It's hardly asking a lot to put three comparisons between && operators.
Remember, though, not to compare string fields with ==, you should call .equals on the string fields.
p.s. don't let the bean terminology confuse you. Beans are just ordinary objects which follow a few rules. Personally I wish the term had never been coined.
