Connecting to different databses simultaneously

Hi all,
I need to connect to three different oracle databases simultaneously. The data I am looking for might reside in any of the 3 databases. So I want to query all the 3 databases simultaneously with a key.
I am planning to use three drivers and three connections in JDBC. But I feel it will have impacts in the performance of the application in the worst case. So is there a way to connect to more than one database simultaneously using JDBC?
Thanks in advance

Is the connection in connection navigator or in a JDBC application?
In a JDBC application three different databases may be connected to by specifying a different connection url for each of the databases.

Applet problem of databse connectivity on different databse server

Hello Friends
I am working on chat application using applet.
But simple applet throw exception for different database server than application server.
So how can solve this problem ?
Is Signed Applet a solution ?
If yes how to develop signed applet ?

Basically it's not a good idea for applets to try and talk to databases etc. directly. Your applet talks to the sever via http and the server takes care of any database activities etc..
For a start, your database shouldn't be visible through your firewall, and it's likely, even if it was, the user's site's firewall would block it anyway.
If it could get the connection your database would be wide open to hacking.
In principal you could enable a connection by signing the applet, or by modifying the client policy file but it's not the right way to go.
And if this is just a local application on a controlled set of machines then what's the point in using an applet, when a GUI program would be more flexible and powerful?

To execute a script in two different instances simultaneously

Hi,
Registered Servers meets your requirements.
The Query Editor window in SQL Server Management Studio can connect to and query multiple instances of SQL Server at the same time. The results that are returned by the query can be merged into a single results pane, or they can be returned
in separate results panes. As an option, Query Editor can include columns that provide the name of the server that produced each row, and also the login that was used to connect to the server that provided each row. For more information about how to execute
multiserver queries, see
Execute Statements Against Multiple Servers Simultaneously (SQL Server Management Studio).
To execute queries against all the servers in a local server group, right-click the server group, point to click
Connect, and then click New Query. When queries are executed in the new Query Editor window, they will execute against all servers in the group, using the stored connection information including the user authentication context. Servers
registered by using SQL Server Authentication but not saving the password will fail to connect.

Time Machine: Backup folder changing size when connected to different computers

Can someone please help me wrap my head around why the size of my Time Machine backup folder changes when connected to different computers? I tried to be as thorough as possible. Thanks in advance for taking the time to read this.
I made a backup of my one laptop (MacBook Pro running 10.6.8) before installing Mavericks. The backup folder size is 258.56 GB and it is on a 1TB WD external. There are no other computers backed up in this folder.
Last night, I tried to copy the backup folder to another 1TB WD external and ran into the “you can’t do that” message. After some researching, I came across articles explaining how Time Machine handles HDs and, in order for me to copy my backup folder, the drive I want to copy the folder to needs to have the “Ignore ownership on this volume” deselected.
Okay, so here is my situation: I have the “Ignore ownership on this volume” deselected and journaling is correct on the drive I want to copy the backup folder to. So I can continue working on my laptop, I want to use a different computer to copy the backup folder from one HD to the other. The problem I’m having is each computer I own is showing me a different backup folder size O.o.
(1) The computer I want to use – a Power Mac G5 Quad running 10.4.11 (non intel) – is showing a backup folder size of 592.7 MB, but the HD shows there is 258 GB being used. When I drag copy, I only get a 592.7 MB backup folder. For some reason, the backup folder is the only folder acting this way. I compared other folders from the same and different externals and all the sizes match up perfectly no matter the computer they were connected to. How is this possible?
(2) My second option - Mac Pro (early 2009) running 10.9.4 – is showing a 256.15 GB backup folder size. Very close, but not 258.56 GB.
(3) My last option is to use the computer I’m trying to stay away from, the MacBook Pro running 10.6.8. This is the computer I backed up and is showing me the correct folder size = 258.56GB. As I mentioned, I'd like to work on my laptop while copying the backup folder using one of my other computers.
I am able to drag and drop from each computer, but the folder size depends on the computer I’m using. I don’t understand why I can't do a simple drag and drop of a 258 GB folder.
Many thanks!!

The directory files that you are seeing are not real. They are links to the actual backup files that are stored in a hidden directory on the drive. If you were to look at the same drive on a pc, you would see the folders and you would a list files that are in the folders but the files would all be 0 byte files and Windows will tell you the file is empty because there is nothing there but a link which Windows does not understand.
So the point is you can't just copy the backupd files. The best solution that I know of (and maybe someone else will chime in) for copying them is to mirror the drive with something like Carbon Copy or some other program.
See this site for more information about time machine and how it works: http://pondini.org/OSX/Home.html

Connecting a Different Speaker to the S750

My computer decided to create an error that shot a high pitched garble throughout my speaker system. Needless to say thankfully it seems it only ruined one speaker the center channel.
The center channel only produces sound from its midrange woofer now. If there is a fix for that i'd love to hear it.
For now i have an old sony center speaker to replace it with. Just curious if its ok to connect a different speaker to the s750. Its power rating its around 70watts rms.

Any 8 ohms speaker will work! Or you could just get the MC100.

HP Color LaserJet CP2025dn Printer Wired Connectivity and have USB simultaneously?

Hello to all;
Thank you in advance.
I have a HP Color LaserJet CP2025dn Printer.
The question, can I use ethernet connection and have USB simultaneously? Ethernet is faster, right?
Currently, I have the printer connected to network via Ethernet Wired Connectivity through an Apple Aiirport Extreme base station. I have several Mac's all operating under 10.9.1, and two PC's (one is WIN XP, and the other WIN 8.1), which all operate fine with 2008 wired/wireless technology. I know what a dinosour. I am in the process of upgrading the household to current wireless technology with a NetGear AC1900 Nighthawk Smart WiFi Router (Model: R7000), 802.11ac Dual Band Gigabit, with two USB ports ((1) 2.0 and (1) 3.0) . I connected the printer directly into the Netgrar router, and it wouldn't print, ran setup through the Mac and Win computers and still wouldnt pring. One of the reasons that sold me on the Netgear router was the ReadySHARE® USB access—Wirelessly access & share. In order for me to utilize the ReadySHARE® feature is to connect via a USB cable. Sob story, the longest USB cable off the shelf usually 16", and to reach where the printer is now, I need @25-28 feet of cable. Is ther a maximum length of USB that I can use with out suffering loss of speed/functionality?
Again thank you for your time

I am sorry, but to get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial printer. You can do this at http://h30499.www3.hp.com/hpeb/

FR Studio - Is there a workaround for the issue with referencing data from a grid with a different DB connection and different # of dimensions?

Hi,
I am trying to reference a column in a different grid with a different database connection. I did some research in the forums, and it seems like this is a known issue with FR Studio. The issue is that if the 2 different database connections have different # of dimensions, then the reference will throw an error.
For example, what I'm trying to do is below:
In grid2.column[A], I have the following formula:
grid1.column[A]
The result is an error.
The ultimate goal is to have a basic variance formula in the grid between grid1 and grid2, which have different database connections with a different # of dimensions. Is there a workaround at all to this bug? The example of the basic formula is below:
grid1.column[A] - grid2.column[A]
Any help is much appreciated!
Thanks,
Tiffany

Thanks for the detailed response Mike.
The issue with trying it in Grid1 vs Grid2 is that Grid1's DB connection has more dimensions than Grid2's DB connection. I can't change the DB connection to a database with more dimensions because you have to be able to map all dimensions from the existing DB connection (Grid1) to the new DB connection (Grid2). This isn't possible, so instead I have to map Grid2 (less dimensions) to Grid1 (more dimensions). It just ignores the extra dimensions from Grid1. Does that make sense?
Thanks again for your responses. It's very much appreciated.

ITunes Automatically Change EQ Setting Based On Which Airport Express Streaming? I have two Airport Expresses running at my house. Both are connected to different types of speakers. Neither speaker set has its own equalizer, and both require a different

I have two Airport Expresses running at my house. Both are connected to different types of speakers. Neither speaker set has its own equalizer, and both require a different EQ setting to sound just right. Does anyone know of a way to have iTunes automatically change its EQ setting based on which Airport Express it is streaming to?

I'm in the same boat. I have a 6 zone amplifier running with 6 airport expresses to different rooms inside and outside the house. Each has it's own acoustic characteristics. I'd really love to be able to set each airport to equalize based on my SPL frequency sweep I did for each room.
Setting the eq in itunes won't do it as that is global plus I have many more sources for auiod other than itunes that use the AEs directly.

NAvugate to SAP BusinessObjects->All products and the select the product you want eg. BusinessObjects ENterprise or Universe designer and the appropriate version XI 3.1. Take a look at the admin and the user guides.
Currently the Data FEderator will allow you to buid a universe that access data from various data sources. Another option is to merge queries from different universes at report level.

How to connect two different tables from different server?

Dear all expert,
I need to develop a report where i need to connect 2 different tables from 2 different servers. For examples:
BUT000 tables from CRM and KNKK from R3.
Is it possible to do so? Because i try to link these 2 tables together and when i preview the report, it run very slow and sometime it hang. I did not get any result.
Thank You.

Moved to SAP Integration kit forum
Appears you are using SAP data sources.
And yes you can but the linked field types must match and be able to be converted into the WHERE portion of the SQL. Click on Database, Show SQL... and see if there is one. If not CR can't figure out how to so it brings all data client side and filters on the second pass.
Thank you
Don

One file to two different folders simultaneously?

Is there a way to copy one file to two different folders simultaneously?
Maybe a script?
Drew

Thanks for the response Baltwo.
Maybe I shouldnt have said 'simultaneously'.
What I'm trying to achieve is this.
I drop a file into one folder and it automatically copies to ano folder (a redundant back up of the first folder)
Is that possible at all?

Error The PC and the printer are connected to different networks

Hi,
I'm trying to set up my C4580 on my laptop, but I'm getting the following error after the diagnostic test:
The PC and the printer are connected to different networks(237DB2A87D and 66616B65). They must be connected to the same network. This can happen when you use the manufacturer's default network name (SSID) and another nearby network is using the same name.
My setup is a Linksys router WRT546, my laptop is conntected wireless to the router. I have two other desktop computers that are directly connected to the router. Both the desktops are able to connect wireless to the printer. My router SSID name is 'Blair Office' with WPA security.
I get a internet connect fine with the laptop, but can't get the new printer to setup.
I saw another post that talked about 'Print the C45** Network Configuration Page', but not sure how to do this
Thanks
Diane

This reply may be late for this user, but it might be helpful for any current users.
I managed to change the modem's IP address to match that of the printer. In my case the printer worked fine wirelessly until I moved to a new place and installed a new modem. Here is what I did to solve the problem:
1. At the printer, click on the wireless button, wireless settings, print network configuration page. This will print a page with the printer's IP address (in my case: 192.168.0.13)
2. I accessed my modem via the internet browser, typing 192.168.1.1 (this is one of the default addresses (192.168.0.1 is also common). Default user and password is admin (usually). There I changed the modem's IP address to 192.168.0.1 and the range to start at 192.168.0.13 (my printer's IP address).
3. I saved the settings (the modem will reboot and you will be offline, it may take some 20 seconds before the modem is visible again).
4. Reconnect to the modem and check if internet is still working. Then try to install the printer again.
This worked for me after I read several other postings.
Good luck!
