Work schema in another database?

I am creating data server and physical schema, one question is:
Is it possible to set up work schema in another db instead of source/target dbs? from the set up drop down, I only can see the schema from current db, even I have db link.
Since it is difficult to get priviledge to create new schema in source and taget dbs, and dba doesn't like it.
Please help, thanks.!

This defeats the purpose of the work schema. We use this area for our LKMs, to load into the data server where the target exists. Also, any work that is done to integrate in the IKM should always be done local to the target data server.
You should have have a frank conversation with your DBA about the architecture of this tool, and how it's designed to utilize the source and target databases for EL-T.

Apex on one database, application schema on another database

Hi Forum
I need your help to let me whether following scenario is possible in Apex or not.
Currently we have a database that has application schema running on server A
We want to install another Database on another server ( server B) and install and configure apex on that.
Can we configure Apex that we installed on B access to database on server A?
if yes, can you please provide some hints how to do that or you can provide a link to web page.
Sincerely

Hello,
Yes you can achieve that by using database links, take a look at this link for the syntax -
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/statements_56a.htm#2061507
you can then query etc over the link -
SELECT * FROM employees@remotedb;Note that there will be a performance overhead in operating on the remote data rather than having it 'local', so for certain data (like lookups etc) you might want to consider the use of materialized views to store a local copy of the data.
Hope this helps,
John.

How to copy file from one table to another table at another database

I need to transfer my tables from one workspace and schema to another workspace and schema. Basically I need to create again all the tables at this new schema. How could I transfer data from tha table at old schema to the table at new schema when this table has files stored in it? (data type is blob)
thank you so much,
Silver

Hello Silver,
Depending which database you're using (if it's available) I would recommend to use datapump.
Datapump allows you to copy an entire schema to another database, it's the "new" export/import you might now.

Question on Exporting Table Stats to another database

I have a question exporting Table Stats from one schema in database A to another schema in another database B.
Currently running Oracle 9.0.2.6 for unix in both prod and dev.
Currently table stats are gathered using the ANALYZE TABLE command. We currently don't use the DBMS_STATS package to gather table statistics.
Question:
If I execute DBMS_STATS.EXPORT_TABLE_STATS in database A can I import them to database B if I'm only using the ANALYZE TABLE to gather table stats? Do I need to execute the DBMS_STATS.GATHER_TABLE_STATS package in database A prior to excuting DBMS_STATS.EXPORT_TABLE_STATS ?
The overall goal is to take table stats from Production in its current state and import them into a Development environment to be used for testing data / processes.
Yes we will be upgrading to Oracle 10 / 11g in near future.
Yes we will be changing our method of gathering table stats by using the DBMS_STATS package.
Thanks,
Russ D

Hi,
If I execute DBMS_STATS.EXPORT_TABLE_STATS in database A can I import them to database B if I'm only using the ANALYZE TABLE to gather table stats? You need using the DBMS_STAT package for get and export statistics process if you want migrate the stats to other database.
Do I need to execute the DBMS_STATS.GATHER_TABLE_STATS package in database A prior to excuting DBMS_STATS.EXPORT_TABLE_STATS ?Yes, you need executing first DBMS_STATS.GATHER_TABLE_STATS.
Good luck.
Regards.

How to create table in another schema of same database

Hi..
I've a database DB1
and has 2 schemas / USers in that..
Usr1 and Usr2...
And i created a TEMP table in Usr1 schema... and created
Then tried the following statement in Usr2 schema...
CREATE TABLE TEMP AS SELECT * FROM Usr1.TEMP;
Then it's giving error that ...
:00942 TABLE OR VIEW DOESN'T EXIST..
What is the reason for that...
Thank you

What other grants do i need to give so as to replicate the Primary Keys also...????That's not a matter of grants. It's the way the CREATE TABLE AS SELECT statement works. It does not copy over indexes, primary key constraints, unique constraints, foreign key constraints, etc.
If you want to copy all that over, you would probably want to get the DDL from the original table (using the DBMS_METADATA package if you're in a recent version), modify the DDL with the new schema name, create the table, indexes, and constraints, and then do an INSERT ... SELECT to populate the data. Or do an export & import of the table from one schema to another.

Transporting large amounts of data from one database schema to another

Hi,
We need to move large amount of data from one 10.2.0.4 database schema to another 11.2.0.3 database.
Am currently using datapump but quite slow still - having to do in chunks.
Also the datapump files quite large so having to compress and move across the network.
Is there a better/quicker way?
Habe haerd about transportable tablespaces but never used them and don't know about speed - if quicker thana datapump.
tablespace names different in both databases.
Also source database on solaris opertaing system on sun box
target database on aix on ibm power series box.
Any ideas would be great.
Thanks

It may be possible, assuming you do not violate any of these conditions

Can i use App schema from another Oracle database.

Hi everyone,
can i use application schema from another Oracle database and how can we do this. the reason is that current database where apex is installed is get very slow because of the size of database and application usage.

You can (using database links), but this will generally result in even poorer performance (unless by "another Oracle database" you mean using RAC?)
It sounds more like you either need to upgrade your systems, or refactor your applications to have a smaller performance footprint.

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.

How to view tables in another schema in the database

I am starting to use the SQl Developer 1.5.
We can connect to an oracle database successfully, expanding the tables, it shows the list of tables of one schema.
We have other schema in the database. In the query panel, when we type in the name of the other schema such as tcs. then some table names will popup in the intellisense.
How can we show the list tables in other schema within the same database.

In SQL Developer left panel, there's a browse tree. There's a 'Other Users' branch under each database, expand that you will see all the option to check user's objects. Your user need to have check dictionary privilege

How to copy one schema into another

I need to copy one schema into another. That means, all the tables, views, constraints, etc, and all the data as well.
I have a dmp file of source-schema (created daily with expdp by our backup schedule).
Can I use impdp to import this dmp file into dest-schema? I'm thinking about something like this:
The dmp file was created with:
expdp source-schema/pwd DIRECTORY=dmpdir DUMPFILE=myproject.dmp
Create the copy on dest-schema with:
impdp dest-schema/pwd DIRECTORY=dmpdir DUMPFILE=myproject.dmp
(dest-schema is an existing schema on the same machine. I'll drop all the tables before executing the command. Is there anything else I should do first?)
If this approach is not feasible, kindly suggest me an alternative.
Thank you.
Edited by: mgro on Apr 16, 2010 3:22 AM (changed 2nd command: expdp to impdp)

Thank you both. Dean, I've made a note of your proposed command. May use it next time.
In the end I used the following command and it worked for me. I added TABLE_EXISTS_ACTION=REPLACE since the destination was not empty.
First I ran these command logged in as SYS
GRANT Import Full Database TO dest-schema;
GRANT Create Any Directory TO dest-schema;
GRANT Unlimited Tablespace TO dest-schema;
impdp
dest-schema/pwd
DIRECTORY=dmpdir
DUMPFILE=myproject.dmp
REMAP_SCHEMA=source-schema:dest-schema
TABLE_EXISTS_ACTION=REPLACE
LOGFILE=implog.log
There were some errors though. The import process complained about constraints referencing non-existent primary keys.
It turns out that the source schema has some constraints that are marked with status DISABLED. These constraints either:
- are not part of the DUMP file
or
- are in the DUMP file but skipped during import
Don't know if this is a bug or by design behavior.

A separate work schema for a physical schema ?

Hi,
The ODI best practices white paper tells us (p.47/48) to create a separate schema and designate that as the work schema for a physical schema. This, however means that the user with which we connect to the database needs to have powerful system privileges like CREATE ANY TABLE, DROP ANY TABLE depending on what you want to do. Many DBA's will object to this. A simpler solution seems to be to set the work schema to be identical to the physical schema.
Has anybody done this and experienced drawbacks/issues with it ?
Can anybody give any good arguments in favor of the best practice advising a separate work schema ?
thanks, Arjan

Arjan ,
I would like to suggest my opinion. The main reason for allocating the work Schema separate to the main schema is to have all the $ tables created separated so that while debugging we can choose to have them and drop them later and also mostly when the CKM is enabled the E$ tables are created and they are not dropped. there are also situation where dynamic $ tables are created so each time you run they $ tables are created and in case of failure or de bugging they remain . On the second attempt we have a new dynamic $ table. Think of a scenario where we have both of them in one place and the amount of unnecessary $ tables we have with our DW tables . Also if such a scenario have to happen in production box. Nobody would like to have such a scenario and then you need to either drop them manually or through another pl/sql codes . Thats the main reason its good to have a separate Work Schema.
Also we use the Work schema for creating stagging table at run time while ODI processing.
Secondly regarding permission and using the schema i have seen both the kind of environment where user used in topology is either the Work Schema or the Data Schema. Yes you would need to give certain permission or priviledges like Drop , create as $ tables have to have them but some dont give permission like Delete , truncate target tables .
Now if you make your DBA understand the architecture , he would surely provide the required permission for the Work schema tables to be created and dropped and i dont see any thing to worry, since $ tables gets created and dropped but yes the permission have to be in such a way the user used in ODI data server dont have the permission to drop the Data schema table , if you want have more restricited permission for truncate and delete too, but in development we would surely need truncate and delete too since we tend to load wrong data and logic . Think about it in a different scenarios and requirement.
Look at this link Cezar has spoken on this topic. -http://odiexperts.com/?p=672
hope this helps.

Accessing another database from HTMLDB

All is there a way to do selects on another database from within an HTMLDB application.

We have several applications on our intranet, all requiring login & password. I was unable to hit the needed tables directly outside the application as I'm not a DBA and they've never given me access to the schema names. So while trying to connect to those same tables as I do with Crystal Reports, I just went to the network drive where the TNSNAMES file is located, hunted for the IP of the server I was looking for, used that SID and did the following:
Database Link Name - (whatever I want)
Connect to Schema - (used my username that I use with crystal)
Password - (same password used in crystal)
Remote Hostname or IP - used stolen IP found in TNSNAMES
Remote Host Port - used port found in TNSNAMES
SID or Service Name - same as in crytal but also found in tnsnames.
After that I had no problem hitting the tables I wanted as my username and login gets me the access I need.
I can't tell for sure why I don't need the actual schema name and why my username works instead. I'm just glad it does as I can now use the necessary tables to do MY authentication scheme without relying having to ask to get access to the scheme used by the department. They wouldn't give it to me anyway:)
Hope that helped, I know it didn't explain why it works tho.
Not sure what you mean by the SQL query... that is done for you in HTML DB in the connect string created by the link.
If you mean how do you hit the link you use it prefaced by the at sign "@" as in gimme what I want from the database @(the link name you made)

Copy data from one schema to another schema tables

Hi,
I was doing a copy using sql developer copy feature, data copy worked perfect but for few table data didn't move there are about 30 tables from schema prod to schema dev i need to move tables are already created only data needs to be moved from prod to dev
Can you suggest me any method were I can move all the tables data at a time from one schema to another. Please suggest.
Thanks
Sudhir

Hi,
If table structure is the same then:
insert into dev.table_name
select
from
prod.table_name --if prod is in another database change to prod.table_name@db_link_to_prod_db
commit
;Hope this helps. Otherwise give some more info about where these schema's are.

Peter

How do I move a table from one schema to another schema on Oracle XE?

How do I move a table from one schema to another schema on Oracle XE?

Hi,
I tried to use the insert/select statement that you had given, it did not work.
The error is ORA-00913: too many values.
But finally what I did was, I went into the system schema where the table was and generated the DDL through the utilities and afterwards I imported them into the schema that I am currently working on. It solved the problem!
However I am still curious to know why the insert/select statement did not work? Do you know any site/tutorial which gives a real time example?
Thank you
