Accessing two seperate databases

Hi, new to discoverer, can a workbook access to seperate oracle databases? If so, how?
Thanks,
Kevin

Yes.
In Administrator, you can change the database parameter to reference tables in a foreign database's schemas.
Alternatively, you can use a custom folder (useful if you want to join local and remote data before presenting it to the user, for example) - just say SELECT * FROM table@remote_DB.

How to compare two fields in two seperate databases

Hi
Can we compare two columns in two separate databases with a one script.
Cheers
Shabar

Hi,
if you mean Oracle to sqlserver then you would have to put hand in pocket and buy ODBC connectivity for this...
If it is just a one off maybe export your data and import into Oracle table and do your one off comparision.

Synching two seperate databases

Is there any way to sync two separate databases tomy 9630 tour?

Ahhh...OK then. So that's Contacts only, I am going to assume. From two separate sources. Challenging. Here is the list of compatible desktop PIMs...since Respond is not in there, I see no native method. However, all is not lost...I can see a few possibilities.
The RIM DTM software can import contacts from a CSV or ASCII file...see this KB and this KB. You'd have to somehow use Respond to export to the format that DTM can indeed read. However, I'm concerned about how this would result on your BB...I'm thinking that you'd have, on your BB, your Contact list and everything would be intermingled with no real way to tell them apart.
Another method might be to export from Respond and then import those into Outlook, assigning categories in Outlook that will synchronize to the BB.
Speaking of which, it sounds as if Respond may already be integrated into Outlook? If so, then enabling those contacts to sync to your BB may be as simple as ensuring that all of your Contacts are in the main Contact folder (in Outlook), divided by Category settings so that you can tell them apart (and apply a filter on the BB).
Or -- Outlook sub-folders can synchronize to the BB...placing all of your Respond contacts into a folder that is sub to the main Contact Folder could also achieve what you seek. See this KB for that method.
As you can see, there are several methods to achieve what you desire. Not knowing Respond is what makes it hard to be precise with a recommendation. But, if it were me, I'd probably go with the last one -- a sub-folder (to Contacts) in Outlook that I then configure to synchronize with my BB.
Hope that helps!

Accessing two seperate networks

Ok here is my situation:
1. There are two completely separate networks. One which is used for the internet(it uses proxy servers) and the other which we use to manage a set of servers at remote locations.
2. I need to be able to access both networks at the same time as my email is web based and I need to copy and paste information often.
Right now I am having to change the service order so I can do both. Is there a better way to do this? A tweak somewhere or software I can use?

I resolved issue using the route command to input the secondary port's subnet and gateway information

One Application server accessing to seperate SID's

Using two MySQL databases at once

I have a situation where one PHP page needs to access two
MySQL databases
for different functions (it's in integration thing). I don't
think I can
combine the databases because two different programs are set
up and using
them separately. Is there a way to do this without PHP
getting as confused
as it's getting? Obviously I'm no MySQL and PHP expert.....

I think I've got it. There might be other tweaks needed, but
I moved the
EasyPHPCalendar table into the same database as the Wordpress
table. With
luck (I'll know tomorrow when I mess with it) that should cut
the confusion
factor!

Querying Tables from seperate Databases

I'm sure this is very simple, but I cannot figure out how to query information from two tables that live in two seperate databases.
Ex.
Select database1.table1.field1, database1.table1.field2, database2.table1.field1
from database1 left outer join database2 on database1.table1.field1 = database2.table1.field1
Any help would be appreciated!

If you are using "database" in the Oracle sense, rather than in the sense that other databases use the term (i.e. a SQL Server "database" is analogous to an Oracle schema), you would need a database link.
In database 1
CREATE [PUBLIC] DATABASE LINK dblink_name
CONNECT TO username
IDENTIFIED BY password
USING tns_aliasThen
SELECT tab1.field1, tab2.fieldN
FROM table1 tab1 LEFT OUTER JOIN table2@dblink_name tab2 ON (tab1.field1 = tab2.field1)Justin

APEX Application accessing data from two different databases

Hi All,
Currently as we all know that APEX Application resides in database and is connected to the schema of that database.
I want APEX Application to be running and accessing data from two different databases. Elaborating my question,
Currently, my APEX Production Application is connected with XXXX Schema of DB1 Database(Where APEX Resides). Now I want to add some pages into this APEX Application for REPORT Purpose, But I want to connect this REPORT APEX Pages to get data from Different Schema YYYY for Database DB2.
Is it possible to configure this scenario?
The reason for doing this is to avoid the REPORT related (adhoc queries) resource utilization effect on Production DB1 Database.
Thanks
Nil

1. If you do the joining of two or more tables in DB1 then all data is pulled over to DB1 and then the join is executed: so more data over the databaselink and more work for DB1. Better keep the joining stuff where the data resides and just pull exactly that data over that you need.
2. Don't know about your different block sizes. Seems a nice question for one of the other forums (DBA or SQL).
3. I mean create synonyms on DB1 for reports VIEWS in DB2.
Hope all is clear!

Accessing MS SQL database with two Windows accounts simultaneously

Hello,
I have ASP.NET web application started under PC\UserName account, and Windows Service Application that runs under Local System Account (NT\System). Both applications should access MS SQL database simultaneously. They are using same connection string:
<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;AttachDbFilename=|DataDirectory|\mydb.mdf;Initial Catalog=mydb;User=MyUser;Password=MyPassword;" providerName="System.Data.SqlClient"
/>
The problem occurrs every time when second app tries to fetch data from database. So, app which connects first can fetch data normally, but the other one gets "Login for
MyUser failed" exception every time.
Everything works as expected when i start windows service app under PC\UserName credentials. But the problem is that i have to do that login every time manually, and when User changes password I have to change it in service settings also.
Does anyone know how to solve this problem?
Thanks,
Mladen

add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;AttachDbFilename=|DataDirectory|\mydb.mdf;Initial Catalog=mydb;User=MyUser;Password=MyPassword;" providerName="System.Data.SqlClient"
Hello Mladen,
You are using a User Instance
of SQL Server and when the first app start this user instance with the MDF in exclusive Access; no other can use this MDF = Single User mode.
Better attach the database file as a regular database, then you can use several connections to access the database.

Is there a way to share one music library with two seperate icloud accounts?

Is there a way to share one music library with two seperate icloud accounts? I have over 12,000 songs in my library and my son likes the same music, but recently his ipod touch is picking up the texts from my wife's and my phone? I was told the only way to stop this is by giving him his own icloud account which would mean he wouldn't have access to my music library. Any ideas?

He can still use your Apple ID for iTunes content, no issues. He just gets a separate ID for everything else.

How do I merge two seperate HD's into one. I upgraded my MBP to an SSD and installed a hybrid in the optical bay.

I intially planned to use my cloned system on the SSD and the Hybrid to be used as backup, media, whatever else. But I only had access to certain program on another MBP and so I cloned it to a partition on the Hybrid. So basically I have two seperate computers each isolated from one another. I have two startup disks, 2 seperate everything. And I have to be careful when syncing my dropbox and a myriad of issues when swithing from one to the other. So does anyone have any questions about this or any suggestions as to how I can merge the 2 so that I can run the initial configuration I desired. Oh and the performance between the Momentus XT hybrid and the Intel-520 ssd are getting closer and closer as time goes by that I almost don't notice a difference, grnted my MBP is only backward compatible to 3gbs so I don't get the performance of the 6gbps capabilities of the intel. But GD its awesome.
I really would appreciate any suggestions. the machine is 15" MBP mid 2010 with 10.8.2.

I don't know that copying them from an external would be any different than doing it internally because they are physically seperated. I have tried many different configurations. It won't let me erase or format the SSD so that I can clone the Hybrid to it. Which is what I prefer to do but I haven't boot from the recovery or an external and tried doing it that way. But even then I have to boot from each seperately, what is holding me up is I've lost both product keys to office and adobe ms 6 due to the fact of not only having them so long and always upgrade using dmg's as well as upgrading os's so often. So those programs are only available on one computer. Which happens to be on a seperate internal disk. A slick unix script would be nice. I am just really tired of trial and error and would like to get back to using my stuff.

Installing multiple instances accessing the same database

Hi,
I want to install two different instances of Oracle 10g in two different machines which will access the same database which will be stored in the shared storage.
Is it possible to install them without installing RAC? The instances will be one active and the other passive, so the services will be up in one server and down in the other and the switching (shutting down one server and starting up the other) will be manual.
Two servers will be running Linux and clustered in Linux level.
Does Oracle offers this solution without installing Clusterware software?
Thank you

> The instances will be one active and the other passive, so the services will be up in one server and down in
the other and the switching (shutting down one server and starting up the other) will be manual
Missed this part as I was thinking proper cluster and RAC.
This is neither. Yes, this can be done using two servers and shared storage.
Is it a good idea? Not really. As this configuration does not provide redundancy at physical database level. You loose that storage.. bye-bye database. Does not matter whether you have a 100 backup servers that can be used.
Thus the business reasons that you are trying to meet with this config have to be clarified and expectations determined.
Separate servers using Data Guard will be a far more superior solution in many respects.

Can I use two different database with DBSystemLoginModule?

Finally I can login with Database user id by DBSystemLoginModule on Embedded oc4j server.
But I confused between [b]jazn-data.xml and system-jazn-data.xml.
Which xml do I have to edit for jdbcUrl and jdbcDriver?
Now I would like to use two different database(such as only sid is different).
In this case I want to show specific database name as realm name.
What should I do?
When I use DBSystemLoginModule, I edit JdbcUrl in system-jazn-data.xml.
So can I pass the parameter for sid programmatically?
And also I tried to run my application with other database with DBSystemLoginModule on Embedded oc4j server.
I changed few things(jdbcUrl at system-jazn-data.xml,jazn-data.xml in embedded-oc4j-server/config and database connection for BusinessComponents at Project Properties of Model/ViewController.
But I got some error.
Did I miss something?

I think I understand now, you are modifing the custom login modules configuration within the system-jazn-data.xml file. This is a bit dangerous! Didn't you register the login module in your orion-application.xml? For example, this is the way I do it:
<web-module id="customProv-web" path="customProv-web.war" />
<persistence path="persistence" />

<security-role-mapping name="sr_developer">
<group name="developers" />
</security-role-mapping>
<security-role-mapping name="sr_manager">
<group name="managers" />
</security-role-mapping>
<jazn provider="XML">
<property name="custom.loginmodule.provider" value="true"/>
<property name="role.mapping.dynamic" value="true"/>
<property name="role.compare.ignorecase" value="true"/>
</jazn>

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
