To connect multiple databases..

in my model
C1 -- interface -- S1 -- interface -- DAS1 -- DB1
-- DB2
-- DB3
i established connection between c1 and DB1..
now im retrieving a field from DB1 and i with that field i want to search in other databases DB2 and DB3 and put all the tuples from DB1, DB2, DB3 as a single tuple.... i dunno how to model this, currently i go this field extracted from DB1 in DAS1 and how can i connect to DB2?
Do i need to place S2 -- DAS2 -- DB2 and pass back the data to S1 then to S2 ?? are is there any simple method to do it???

With another connection, statement, etc.

Alternatively you set it up so the database does this for you using a remote view. Probably easier to code, probably no more efficient particular if you are using different database vendors. And it might not be possible.

JDBC - Connecting Multiple Databases

Hi JDBC's
I would like to know if it is possible to retrive a data from different tables and from different databases using a single query, which mean can I retrive data from multiple tables multiple databases in a single JDBC connection?
If not, How do I implement it?
Any Ideas or please point me to any related solution if you have.
Thanks.

Although theoretically possible in fact a single JDBC connection cannot work with several databases. To implement this feature somebody has to write another aggregating JDBC driver which parse SQL statement and work with other databases in background. I like this idea, but currently there is no such driver available.
Scriptella ETL (http://scriptella.javaforge.com) offers an interesting solutions for cross-database operations. See example on how -to copy a table from oracle to hsqldb: http://snippets.dzone.com/posts/show/3511
If you want to join 2 tables from different databases and copy the result to a third database use the following code:
<query connection-id="db1">
SELECT * FROM Table1
<query connection-id="db2">
SELECT * FROM Table2 WHERE Table2_ID=?Table1_ID
<script connection-id="db3">
INSERT INTO Table3 VALUES (?rownum, ?Table1_Field, ?Table2_Field);
</script>
</query>
</query>

How to connect multiple databases

Hi all,
This is my situation , i need to set the max number of connections to one database , if the connection exceeds then i need to connect to another database , is there any way to solve it? please help me

Sounds like you want to write your own load balancer. Sweet!!
As was already stated, this would be best handled by clustering your database servers.
If it's not done at that level, what's the next best option? How are your users currently connecting to the database? Is it through a web server or from stand-alone clients? If it's a web server, the server should have some facility for creating datasources and pooling connections. If you are dead set on switching to a different database when the number of connections in the pool has been maxed out, then you might have to write your own singleton class to manage the connection pool(s).
If your users are connecting through stand-alone clients, you have to force the client applications to connect through a single server that controls the connections.
There's one major problem with switching databases...if a user saves some data there is no guarantee that they will connect to the same database when they want to read the data at some later point. Maybe if there is replication between the two databases in the cluster, they might be able to do that.

Primavera with Oracel 11g standard edition ( Connecting multiple databases)

I have installed primavera 8.2 with Oracle 11g standard edition. ( After lots of trial and errors )
I installed / Created two databases using primavera dbsetup.bat file for creating new database.
Data base names are PMDB and PMDB2
Currently i am using PMDB with oracle connection string as "ORCL" and database aliase as PMDB and its working fine
"C:\app\xxxxx\oradata\orcl" this location contains both databases physically
I seek your advice how to modify string to access other database ( PMDB1)
because if i have tried with different aliase name but it connect to same database ie PMDB

Is this P6 EPPM 8.2 or P6 PPM? Are you using P6 client or web to connect to it?
If this is P6EPPM then you can log into P6 Administrator and expand database node, create a duplicate node of it and change the database connection parameters. Save it and try to login using P6 Web. Select the correct database from Advance link below Username/Password.
If this is P6 PPM then define tns entries on your machine for both the databases ans use them to configure P6 client.

Create connection multiple database server connection with sinle client

My problem is like this. I have 3 database servers like server A,server B,Server C. First Client will communicate with server A and Server B at the same time. Then if the connection is done then i need communicate with server C. Is there anybody who has the sample code for this. Please help me i am facing problems with this.

I want to build a web site using jsp servlet for my university course purpose. In the background i will have three servers one is database server like server A another is certificate authority server like server B and the other one is Bank server like server C. Next, user will input through login page(say for example user name & password for database server A, certificate credentials for server B) then the login page will check user credentials kept in server A and at the same time with server B(CA server). If the user credentials kept in both of these servers(A &B) are matched then the page will inform that this is the valid user and connect to the bank server for money transaction. I hope now the my problem is clear to you. please answer me how can i prepare for that.
what are the concepts related to that and have any demo code which i can use for that purpose.

How to add multiple databases for a single frontend

We have a project based on distributed databases and we have to workout on .Net framework.I want to know some information of connecting multiple databases for a single frontend and how can we access them.
If so we have connected 2 databases for a single frontend in future if I want add one more database to it how it will be possible to do it without disturbing the current connectivity.
Please help me in resolving this problem.
Thanks......

hi,
what do you mean by connecting 2 databases? can you explain further?
using entityframework you can connect to different databases
public class CustomerContext : DbContext
public ReportContext()
: base("DefaultConnection")
public DbSet<Customers> Customers { get; set; }
and your connectionstring (config file)
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=D:\\Database\Project.mdf;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
you can add more connection strings on it.

Sure you can access a database this way,
but can you base a block on this database connect? No you can't.

Connection to multiple databases using a single EJB

How can I connect to multiple Databases (using @PersistenceContext) using an EJB?
Did I need to connect various Entity Managers corresponding to the each database and simply send my Queries?
I am using Glassfish Application Server
Netbeans IDE
Java Derby Database
Oracle Database
Java Persistence API
Thanks in Advance

Yes, you need a persistence context and thus entity manager per database. Depending on what you want to achieve you may also need to go to the next level in your skill set and learn all about distributed transactions.

Application that connects to multiple databases.

I am developing an application that performs many task, but one in particular is connecting to multiple databases and creating user accounts in each all with the push of a single button. I have tried putting connect statements in the trigger code but I don't get the desired results.
How would I get my application to switch database connections while in execution?
Please reply to the forum, or email me @ [email protected]
Thank you.

Hi
The only possible way which I could find for your requirement is that of DB Links. Establish DataBase Links among the multible databases, with which you want to work in one session. Peform all your actions through the DB Links.

Multiple Database Connectivity

How do we establish connectivity to multiple databases from within one Java Application. And how do we so without any File DSN? We are developing an application which requires dynamic changing of databases located at remote locations. Please help.

you can use a properties file to load the DB details on runtime based on the criteria.
Just put your DB details in a TEXT file and store it as .properties file. You can read it using any input methods from java and pass the parameters to your connection.
Hope this helps.Cheers,
Sekar

Does BO 4.1 enable universe to connect to multiple database?

Using BO 3.1, we can only connect an universe to single database. However, with BO 4.1 will it be possible to connect a single universe to multiple database?

Vinay, You can connect Universe to multiple databases using IDT (Information Design Tool). Find the below link for reference.

Including multiple databases per connection

I have linked tables accross multiple databases and would
like to include all applicable tables (from multiple databases) in
a single dreamweaver database connection. Is this possible. I can't
put all tables in a single database because one of the databases is
a mirror of a quoting application and gets backed up to regularly
which is why I need to keep intact.

>microsoft access, is this what you are asking
Yes, that is what I was asking. But I really don't know the
answer for MS Access as I've never tried. I've worked with linked
tables in Access, but not from ASP. Why don't you just give it a
try. It should take a few minutes to test.

What is stopping you from having more than one database
connection
string? You can select the connection from each behaviour
that needs
different databases.
Or is then intent to combine the data from 2 database into
one recordset?
