How to duplicate a database schema

You can do it with Oracle Datapump (expdp/impdp).
1. Check if there is an oracle directory object on a drive with enough space:
select * from all_directories;]
If not, create one:
create directory g_dump as 'g:\oracle\dump';]
2. Export schema:
expdp system/*** directory=g_dump dumpfile=<File Name> logfile=exp_<file name>
schemas=(schema_name1,schema_name2)]
3. Optional: If you are copying schemas to another server, repeat step 1 on the destination server, then
copy .DMP file there. Keep folder name and directory object same as on the source server, if possible.
4. Import into a new schema:
impdp system/*** directory=g_dump dumpfile==<File Name> logfile=exp_<file name>
remap_schema=<User name>:new_<user name> remap_schema=<User name>:new_<user name>]
Use remap_schema parameter for every user you want to rename. Omit this parameter if you do not
rename users (copying schemas to another database).
If you want to import into separate tablespaces, create these tablespaces, and specify this in the impdp
command line:
remap_tablespace=<tablespace name>:new_tbs remap_tablespace=<tablespace name>:new_tbs]
Note: If you are trying to reimport the schema into the original database
but you are remapping the tablespace, your remap tablespace must read:
remap_tablespace:whatever_tablespace_it_was_in_before:tablespace_you_want_it_in_now]

I'd suggest you to create a blog and post these information on that blog. Forum is for asking questions or answering them

How to duplicate the database/catalog ?

Hi,
How can we quickly duplicate our database/catalog to create a test environment ?
Thanks,
Paul

Do you mean to copy the existing Database ( Schema) into your test environment?
You can Export and Import your schema like this:
File --> Import --> SAP HANA --> Catalog Objects

How to create a database schema

could any one help me with database schema I need create one
thanks!

I am told that I am connected to an idle instance...not sure what this means It means the database is down. Because you connected AS SYSDBA your connection did not fail; if you had attempted to connect as any other user you would have got the ORA-01034 immediately. So all you need to do is startup the database:
SQL> startupBy the way it is considered bad form to resurrect old threads, especially when (as in this case) your issue is not really germane to the original post.
Also, if you're going to tool around in a database as SYSDBA you really ought to familiarize yourself with the documentation: start with the Concepts Guide and the the two-day DBA manual.

How to create the database schema from an existing TimesTen database ?

Hello everybody,
I'm a newbie to TimesTen database. Before doing complicated sql queries, I would like to obtain the database schema of TimesTen DB. I'm looking for a way to extract the schema of database (tables, keys, links between tables ...). When I was working on other db like postgreSQL, I was able to obtain the sql script of the database (for exemple, in order to re-create the database in an other server). Some software like PowerAMC was able to built the database model from these scripts.
Do you know a way to obtain the same with TimesTen database ? Or with an other way ?
Regards

Hi,
Take a look in the docs at ttSchema, this might do the trick.

How to use another database schema in Dictionary project

Problem description:
1)     I want to use Developer Studio to create my own J2EE project. Then I have to use Dictionary Project to maintain my database. My database is Oracle.
2)     I created tables in Dictionary project and deployed to database
3)     After that I found my tables were deployed into SAPSR3DB schema.
Question:
      What can I do if I want to deploy my tables into another schema other than SAPSR3DB? In real cases I want to separate my tables from the WAS system tables.

Hi Chaoran,
If you want to use external database with Java dictionary tables..
Right click on the Java Dictionary Table, from the menu select <b>Create DDL script</b>, then select to which data base you want to generate scripts. It will generate .sql scripts, use this scripts in your database to create tables. But the same time you need to create Data sources in Visual Administrator for your oracle system.

Hi All,
When creating a new entity object, I am facing a problem with database schema objects in the entity object wizard, database schema objects (check boxes for tables,synonyms...) are disabled. Actually I am using a synonym but I am not able to select the synonym check box.
Can any of you folks tell me how to enable the database schema objects (check boxes for tables,synonyms...).
Thanks in Advance.

Using Express when the database schema does not match theclass model

We are working on a large pay/personnel management system and are
evaluating Forté Express and Sage Scaffolds. We need to answer some big
questions in the near future, and I was hoping that there may be someone
out there with the answers.
1. How different can the database schema and the class model be, before
Express becomes a bad choice of framework? What solutions exist for cases
where Express is still a viable option?
2. Assuming that we can get around the problem in question 1, will the
Application Model features still work afterwards? (i.e. how sensitive are
the client-side services to changes in the database services?)
3. Express seems to use domain classes everywhere, whereas we are always
being advised to use scalar attributes wherever possible. How badly does
this affect the performance of Express applications?
4. Has anybody out there used Sage Scaffolds on a large project recently?
How did it go? What problems should we watch out for? Doesn't its 'Chain
of Responsibility' pattern tend to produce a lot of unnecessary objects at
run-time?
5. Has anybody used the Born collection classes? How do they compare with
Brahma's Fortify?
Thanks to those who have already helped - all input gratefully received!

/ I guess my understanding was that I could grant another oracle user access to my registered schema just like I can grant a single user access to a table. Evidently I only have two options. Only the schema owner can use the schema or everyone can use the schema and I cannot grant access to a single user other than myself.

How can I connect to a different database schema,other than adobe?

I'm building an application where I want to use a different database for it,for storing additional data for the users(different from "edcprincipaluserentity" table in "adobe" database stores)..How I can connect to my database schema created in MySQL from Workbench,to assign tasks to my users,using the Process Management/Assign Task service?

You can only assign task to user that are known by the LiveCycle User Manager.
When you configure LiveCycle, you can tell it where you want to get the users from. They can be created them locally in the local database, or synchronized from an LDAP directory in which case it'll read the users from LDAP and make a copy of some of the properties to the internal LiveCycle database.
Bottom line, all users have an id (in the edcprincipalentity table) in the adobe database.
If you need your users to come from a different database, then you need to customize the SPI (security provider interface) so that you can synchronize the users coming from your external database. Again, this is a customization since out of the box, we don't synchronize against external database. But it is possible, the API is there and other customers have done it.
I hope this clarifies things a bit.

JPA: how to organize multiple databases having the same schema definition?

Hi there,
I'm new to Java EE but I could finish some test projects on GlassFish 3 / Java EE 6 platform.
Now it's time to build the actual system and I need some help in that.
So, I can't really tell you the exact purpose of this system but let's look at the following example which is very close to what I need.
Say there is a database schema definition (DDL) for Oracle 11g and this schema is storing the inventory of a shop. So tables like product, category, price etc
Say there are 50 shops, and I'm getting a new database for each shop every month holding their inventory.
So every month I'm receiving a SQL file with INSERTs (DML) for every shop for the DDL I mentioned above.
I'm getting 50 SQL files for the 50 shops every month, so in a year you're talking about 600 SQL files to import.
If it was php/MySQL I could import them into a separate database each, call it shop1_May11, shop2_May11 etc reflecting the shop name and the month in the database name.
This is my question how you guys think I should achieve this in Jave EE / Oracle.
As the DDL is the same I thought to create an Entity for each table and use the Java Persistance API to create the databases and then I'd import the month/shop specific SQL files.
But this means I'm gonna create 50 new schemas in Oracle every month?
Or what's the best way to achieve this?
Thanks in advance

JPA helps a lot in persisting and retrieving data that has relationships without having to worry about the relationships at a sQL level.
So you get a java programmer that builds relationships using Java classes (the entities) and a persistence provider worries about the sql required to materialize those relationships.
You seem to be using SQL inserts for persisting the data and you want to generate the reports from SQL as well.
You can use it but you won't be gaining much of its advantages for this project.
Consider reporting applications like the jasperserver for the reports.
Also, I have seen people get away with using one database for this type of thing and just adding a clientid (and optionally branchid) to each table.

How to change database schema of data source in OWB?

Hi,
Could someone give me hint about my questions:
I select many database schema in TOAD. like "My Shema" and "All Schema".
If I create a Oracle Data Source in OWB 10.2. All tables/viewsI can see only from "My Schema" (I think it is default), However, I need to connect "All Scema". There are lots of prod tables/views. I don't know how to set/change/config in OWB even reading guide.
Thanks a lot
Lan

Lan,
You can ONE of the following:
1. Dbl click the src/target module and go to metadata location tab and select a location that has the details pointing to the different schema (If you do not have this location created, you may have to create one).
2. Create synonyms in "My Schema" to objects from other schema. Then try to import the tables again. This time you will be able to see the other tables (the icon will be different for synonyms.)
Hope That Helps.
Kaushik.
