Setting up different databases

I need some help in uderstanding how data bases are setup in Oracle.
Let me be more specific. In Access one can setup a different database and "save" it. One can then create tables within each of these "independent" databases.
Can one do the same with Oracle ? I seem to always be working with just one database [and all the tables in that database]. When I log into Oracle [8i] I don't seem to get a "choice" of databases the way I do in Access.
I would appreciate an explanation [or comments] on this.
Thanks

this is the section from new features list I had on mind:
Release Notes
1 New Features for Oracle Database Lite 10g Release 3
1.9 Store Application Data in Separate Databases
By default, all application data is stored in the same database as the Mobile repository. However, you can register other Oracle databases as the repository of the application data. Once registered, then during the publication creation, specify the database where you want the application data to be stored.
This feature should allow you to use two (and even more) different database schemes for your sync snapshots if I understand it right. I didn't test it yet to verify it unfortunately. So if you'd test this new feature than let us know, please..

Data from different databases in the same report.

Hi Everyone,
I am trying to build a reconciliation report in which I need to show the data from the source and target, side by side.
Source and target are both different databases, although being oracle only
Whenever a new data model is created, it gets attached to a data source and in the report we need to choose a specific data model.
Can we have data from different databases in the same report ?

Yes, it is possible.
One way Is to use dataTemplates. There you can make queries from any number of different databases (The max I have done is 5).
It looks something like that:
<dataTemplate name="NameOfTemplate">
<dataQuery>
     <sqlStatement name="Q1" dataSourceRef="Connection1">
          <![CDATA[     select * from table1]]>
     </sqlStatement>
     <sqlStatement name="Q2" dataSourceRef="Connection2">
          <![CDATA[     select * from table2]]>
     </sqlStatement>
</dataQuery>
<dataStructure>
     <group name="RESULT1" source="Q1">
          <element name="P_FIRST_NAME" value="P_FIRST_NAME"/>
     </group>
     <group name="RESULT2" source="Q2">
          <element name="P_DATE" value="P_DATE"/>
     </group>
</dataStructure>
</dataTemplate>dataStructure is very important when you get data from different places, if you don't define those elements, then only the result from Q1 is shown.
The second possible way is to make as two different data models, each containing their own query and then set Main Data Set as concatenated SQL Data Source.
Best of luck,
Evelyn

SQL Server wants to open properties of wrong database and cannot restore logs of different databases at the same time

We have implemented our own way of logshipping by backing up the transaction logs of all our non-system databases every hour. Then we transfer the backups (before SQL Server 2008 R2 with additional zip and unzip steps) to the second environment where we
restore them only during the night on databases in standby-state (Like this, our developers can access the databases without disturbing the productive system and we can restore the t-logs during night, so not shutting out the developers during the day).
Now since we replaced our hardware in the productive environment, we replaced the hardware in the second environment with the servers from previous productive environment. Same SQL Server 2008 R2, same Service Pack (SP2), same installation procedure. But
since then the SQL Server in the second environment behaves different:
- When the logs of some database "A" are restored, I cannot access the properties of any database, i.e. database "B", I only get the error message "Cannot show requested dialog. (SqlMgmt) Database 'A' cannot be opened. It is in the
middle of a restore. (Microsoft SQL Server, Error: 927)"
- Our logshipping runs multiple instance at the same time, so restoring multiple databases' logs. But since the change, two of the instances fail restoring of datatbases, i.e. "B" and "C" with the error message "Database 'A' cannot
be opened. It is in the middle of a restore.". The jobs guarantee to restore only logs of the database they need to restore, they have strictly separated sets of target databases and only try to restore the databases of their sets.
Before the new installations, we did not have these strange behaviours. But as said, it is the same SQL Server version, the same service pack, and we followed the same installation document but maybe with the small changes in settings. The user the jobs
are running under is a domain admin, the login they use has dbcreator, processadmin, db_owner and db_backupoperator roles. My login on the SQL Server has sysadmin rights and as described similar problems.
Is this problem known or does somebody have an idea where to go looking for?
Thanks, Chris

Hi Christar,
According to your description, after you configuring Log shipping between two database, you remove the hardware from production environment to dev environment, in this hardware, there are saved the transaction logs of your database.
When restoring your database, there will occurs error 927, right?
SQL Server Log shipping allows you to automatically send transaction log backups from a
primary database on a primary server instance to one or more
secondary databases on separate secondary server instances. It consists of three operations:
1.Back up the transaction log at the primary server instance.
2.Copy the transaction log file to the secondary server instance.
3.Restore the log backup on the secondary server instance.
Since you want to move your hardware avoiding copy job, we need to verify if .mdf and .ldf file are not saved in your hardware, or else,
if you move your hardware, you could not open your database in your Primary Server. I recommend you can refer to the following steps.
Full back up your primary database and restore it into the secondary database. It would have been set up as WITH STANDBY ,the databases would read StandBy/ Read Only.
Perform transaction log backups via a SQL Server Agent job running on the primary server instance, save them in your hardware.
In night, you move hardware to your dev environment, you can manually restore these transaction log backups or set up a SQL Server Agent job to restoring them from your hardware.
There is detail about how to configure log shipping in SQL Server 2008R2 step by step, you can review it.

Work repository on different database configuration

Hello there,
I am trying to set my work repository to be a schema on differing database to the source dataserver.
Currently when I edit the source data server and try to set the work repository I only have the option to select schemas from the source.
I have my work repository on a different database.
Can anyone help?
Regards,
CM

I have come to a conclusion that there has been a confusion over the terminologies. What you call "Work Repository" is actually a "Work Schema" in your specific case.
Then the answer is that Work Schema needs to be on the same data server as your Source Schema.
Below is a reasoning behind that:
This schema consists of temporary/intermediate work tables that are generated by ODI knowledge modules.
These work tables are similar to tables in source schema in terms of data and structure
Data is moved, copied and compared between source schema and work schema, it makes more sense to store them on the same data server to avoid any network/communication overhead.
Hence ODI warrants that the source schema and the work schema exist on the same data server.
P.S. "Work Repository" is the metadata repository that holds the data model definitions, ODI code, packages, interfaces, etc.
It works in tandem with "Master Repository"
Hope this helps you.
If you feel that your question has been answered, please mark the question as answered and all the answers that you have received as helpful or correct.

About listeners for different databases in the same ORACLE_HOME

Hello experts, I have a doubt
I have installed 3 different databases in the same server which OS is Suse Enterprise 10. At this moment I have just one listener that registers all the services. The number of connections are big for two of the three databases so I do not know what might be the best practices for this environment. I have some question I would like you suggestion for me:
DB version: 11.1.0.7
Should I have three listener, one for each database?
Is a good practice to have only one listener for multiple instances in the same server?
Are there differents between have only one listener for all the instance and have one listener for instance?
What about the performance?
Than you in advance, I hope you can guide me.

Best practice is not to have multiple databases on one server, depending on resources.
Should I have three listener, one for each database?
No. That is pretty undesirable and requires more administration.
Is a good practice to have only one listener for multiple instances in the same server?
Yes. Remember the listener is only a broker and there are no permanent connections between client, listener and database.
Are there differents between have only one listener for all the instance and have one listener for instance?
Yes. The latter is an administration nightmare.
What about the performance?
Who cares? The only factors are
listener.log becomes too big --> set up proper cleanup procedures
The number of semaphores is exceeded (Unix) or no more threads can be created (Microsoft winblows), which will give rise to ora-12500.

Rpt-files do not function anymore after deploying to a different database

first: I use CR. 10.2.3600.0 and Asp.NET with Visual Studio 2005
I developed my reports against a Develepment-Database and everything worked fine.
Then, I published my Website with the reports.
Also I made a backup of my Develepment-Database to become the Productive-Database.
All pages of my website function well (database-queries etc.), but when I try to call one of my reports a queerish error message occurs:
"This field name is not known. Error in File C:\WINDOWS\TEMP\...\{...}.rpt: Error in formula. '{xyz.ds_id} = {?@ds_id} and '."
I mean, the database is the "same" as before?!?
(BTW: the logon to the database is set at runtime and is ok.)
Why do the reports not function anymore?
The only workaround I found is to open the report in Visual Studio 2005 again and select "Crystal Reports/Databases/Check Database" against the Productive-Database.
After that the report works! BUT THIS COULD NOT BE THE SOLUTION, this means that I cannot publish my website to a different database on a customers network!!!

I tried this:
Private Sub SetDBLogonForReport(ByVal myConnectionInfo As ConnectionInfo, ByVal myReportDocument As ReportDocument)
        Dim myTables As Tables = myReportDocument.Database.Tables
        ' Get Location of Database from web.config
        Dim Location As String = String.Empty
        Try
            For Each myTable As CrystalDecisions.CrystalReports.Engine.Table In myTables
                Dim myTableLogonInfo As TableLogOnInfo = myTable.LogOnInfo
                myTableLogonInfo.ConnectionInfo = myConnectionInfo
                myTable.Location = myConnectionInfo.DatabaseName & ".dbo." & myTable.Location.Substring(myTable.Location.LastIndexOf(".") + 1)
                myTable.ApplyLogOnInfo(myTableLogonInfo)
            Next
        Catch ex As Exception
            Me.LabelError.Text = "(SetDBLogonForReport) " + ex.Message
        End Try
    End Sub
and get the error:
ex.Message     "Fehler beim Laden der Datenbankinformationen.
Details: Die Datenbank-DLL 'crdb_query.dll' konnte nicht geladen werden.
Fehler in der Datei C:\DOKUME~1\MSCHAE~1\LOKALE~1\Temp\RzpReport {748C95B6-70EC-45B9-953D-64DA215BD9DC}.rpt:
Fehler beim Laden der Datenbankinformationen"
which means in english:
ex.Message     "Error while loading database information.
Details: the databse-dll 'crdb_query.dll' could not be loaded.
Error in file C:\DOKUME~1\MSCHAE~1\LOKALE~1\Temp\RzpReport {748C95B6-70EC-45B9-953D-64DA215BD9DC}.rpt:
Error while loading database information"
I debugged the code and recognized that the error appears while setting the .Location property...?!?
My DatabaseName is "Rezepturverwaltung".
Example 1 with a command:
Befor setting the Location of mytable the value of the prpperty is e.g. "command".
After setting the value like in code above the value changes to "Rezepturverwaltung.dbo.command"
Example 2 with a stored procedure:
Befor setting the Location of mytable the value of the prpperty is e.g. "sp_GetData".
After setting the value like in code above the value changes to "Rezepturverwaltung.dbo.sp_GetData"
What`s going wrong furthermore???

Cookie being used in different applications which are on different database

Hi,
I have two htmldb applications. One app (App1) is on database DB1, and the second one (App2) is on database DB2. App1 will create a cookie, and App1 will use URL to redirect to App2. App2 will use the cookie which App1 created.
The problem is in App2, I used owa_cookie to get the cookie but, it is not there.
I know different htmldb applications in the same workspace (in the same database) can share the cookie. Can the htmldb applications in the different databases share the same cookie?
Thanks.
June

Scott,
Thank you for your reply.
In App1, I have set a cookie as following:
begin
owa_util.mime_header('text/html', FALSE);
owa_cookie.send(
name=>'LOGIN_USERNAME_COOKIE',
value=> 'abcd');
owa_util.http_header_close;
exception when others then null;
end;
App1 in DB1 accesses source(URL) App2 (eg: http://mymachin.domain.com:7778/dbname/f?p=100:101).
App2 in DB2 has a process (On Load -Before Header) in login page to get the cookie:
declare
v varchar2(255) := null;
c owa_cookie.cookie;
begin
c := owa_cookie.get('LOGIN_USERNAME_COOKIE');
:P101_USERNAME := c.vals(1);
exception when others then null;
end;
I just want to pass the username from App1 to App2.
Is there any way the cookie can be shared in my case?
Thanks.

Calling pl/sql package on different database in process flow

Hi there
Have a process flow which calls procedure on different database. This procedure truncates a table on the remote database.
Please could somebody confirm we would need to set up dblinks from the owf_mgr schema to the remote database.
New to wokflow - am i Correct in assuming the process flows run on the owf_mgr
rather than the control center owbrt.
Many Thanks

Hi there,
Thanks for the reply.
If my understanding is correct I could have a procedure as follows.
hkeeping.trunc_table@dblinkname('TABLE_NAME');
Is this the case?
Another alternative was to call directly the transformation in the process flow
e.g. we have pl/sql package on remote database whioch truncates the remote table.
When we try this with same procedure on same databas as owb user exists on then works fine.
However on remote database get message below. Does this mean anything to you? How could we sort this?
RPE-01003: An infrastructure condition prevented the request from completing.
  TEMP_PLOW:TRUNC_TABLE
Error
RPE-01038: Failed to evaluate expression null. Please modify the expression, redeploy and retry again.

Maintaining formats(layouts) on Crystal report with different database

I was just needing some help maintaining the layout of a report but using a different database. The databases are very similar for example, a field for the database in use is line1xxxx what I wish to do is keep all the formating & point it line2xxxx database. Where line1 is the original Database & Line2 is the new database I wish to use. Both of these databases reside in the same folder its just that I need identical reports for both Line 1 & Line 2 & am trying to get away from duplicating all the work I did on the Line 1 report.
Hopefully not too trivial for this forum.
Thanks in advance.

If you have same tables in both the databases then open the report and go to menu option in the report database-->set data source location and create new connection in the bottom window and select both existing connection from top window and new from bottom and click on update. Now the report points to the new database, so now use save as option to save the report with some other name so that you can have the old report with old connection and the new one with new connection.

The syntax of your UPDATE statement is incorrect.
Have a look at the "wire-diagram" in the documentation -
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_10007.htm#SQLRF01708
and compare it with your UPDATE statement.

Connecting to two different database instances from a swing application.

Hi All,
I am developing a swing application which needs to interact with two different database instances of two different weblogic servers.
More eloborately,
I have some data in DB_Instance1 running on[b] Weblogic_Server1 and I need to insert the same data into DB_instance2 running on Weblogic_server2. Is it possible. Could some explain me how to do that..
Thanks in advance...
Sreekanth.

Hi Rick,
Try logging onto both Server first. You'll have to use either 2 separate ODBC DSN's or 2 separate OLE DB connections. Set them both for Trusted Authentication, you'll have to configure that on the Server also.Then try your query.
If that doesn't work then you'll have to create a Stored Procedure or View that can link the 2 Server side.
Thank you

How to integrate different tables structures from different databases?

Hi
I'm new to oracle ..kindly help me with the below issue...
I have same set of inter-related attributes (a,b,c,d) in two different databases A and B.
The structure of tables in both the database are different but they carry same attributes in same relation.
I have to integrate these attributes into single db object such that any update to base tables updates my object.How can i do this and what object will be helpful?
Thanks

Dealing with tables from different databases?

Hi. I'm a newbie to Visual Studio 2012 and stuck on how to interact with different datasets.
I am building a report that is associated with with two tables, each from a different database. The
master_flat table with the primary key matter_number is from the first database and it contains all the columns I need that should show up in the report layout I've built. However,
billing_table with the primary key matter_number contains a flag that I go by which I must use to determine whether each matter should come through in the reporting or not.
I've set the master_flat as dataset1 and the billing_table as dataset2. Now, what is the best way in Visual studio 2012 to filter by the matters that has flag "N" in dataset2?
Thanks

We are way out of sync. Lets synchronize. I'm not sure which question you are refering to. Is it the "C# or VBnet" question or is it the "One or two database Question". It seem like it would be the database question since you
should know which programming language you are using.
Open SQL Server Management Studio (SSMS). After login, there is an explorer where you can browse the databases, tables, and fields in the tables. You should be able to view how you build the database. If you right click any tables and then
"Script Table As : Select To : New Query Editor Window". There is an execute button to run the query. You can aslo edit the query. I usually test all my qeuries in SSMS before actually using them in an application. I would get a JOIN
SQL working in SSMS.
If you let me know if you are using VBnet or C# I will write a simple LINQ. Even better if you supply me the names of the columns of the two tables.

How to do mappings in owb with different databases

hi all,
I have two different databases with in same server one for staging and target.
How to connect both target and staging databses to do the mappings using OWB??
Is it possible?? if possible how to do the mappings??
for ex:
Now i registered my OWB with bcp database for both staging tables and target tables.
now i want to load data of staging tables into bcpsource database and
target tables into bcptarget database seperatly.

10gR2 does have connectors. They were introduced at the same time as locations.
The connection attributes (eg host, port, tnsname) are set against the location, not the connector. A connector simply defines the fact that there is a path from one location to another (eg via a database link). All the connection information remains on the location object.
The process flow packages within a location can each be deployed on their own simply by selecting the location in the Control Center Manager, and setting a deployment action against the package (or by using scripting, as mentioned). However, a process flow cannot be deployed independently of it's package - it's all or nothing.

View running slowly on different database

Hi,
I have an issue where a view which runs quickly on two different databases runs slowly on a 3rd database. The database schema is the same on all 3 machines. The two databases that run the view quickly are v.9.2.0.1.0, and v.10.2.0.2.0, the 3rd database that runs the view slowly is v.9.2.0.7.0. The physical machine that the 3rd database runs on is the fastest machine.
On the poorly performing database, if I set autotrace on, then I get this:
Statistics
36 recursive calls
0 db block gets
618169 consistent gets
10 physical reads
0 redo size
406 bytes sent via SQL*Net to client
499 bytes received via SQL*Net from client
2 SQL*Net roundtrips to/from client
1 sorts (memory)
0 sorts (disk)
obviously, the sheer number of consistent get's has to be the source of the problem.
explain plan doesn't reveal anything obvious.
I'm struggling to resolve the issue. Any help or pointers would be appreciated.

The indexes are the same. I've also tried rebuilding the indexes.
