Detaching and Reattach ndf files from different copies of a database

Hi,
This question may be very basic, but I'm wondering if it's possible, and if not what is the technical reason behind it.
I have two databases, Database A and Database B. What I would like to do is truncate the tables in database A, detach it and make a windows copy of the files to another area, then reattach these files to database B. Everything is identical schema wise
apart from the database name.
Is this possible? If not, why?
Thanks for any help.

Hi bro
1. If i am not wrong you mean to say you dettach database A data and log files and attach with different name as database B-----> Yes its possible.
2. If you want to detach database files fro database A and want to attach to another database already running named database B ---> No its not possible
reason : a. You cant attach any file to any database when its online means database is already in use and adding file means making it in consistent. refer
Acid properties
b. Other database is not aware of this new file, so you can only create new file cant attach nay file

Read XML file from different server on JSP

Dear All,
I am a newbie to JSP with XML, now i want to read the "test.xml" from JSP.
I read successfully this "test.xml" file from my system and I got output, but I need to read the xml file from
different server like "http://www.domain.com/test.xml". I couldn't read such a type of file from different server.
Is it possible to read a xml file from different server?
If anybody have idea please let me know.
Thanks in Advance,

You might try:
Document doc = docBuilder.parse ("http://www.domain.com/test.xml");Alternatively use the java.net package to obtain an Input Stream to the xml document
InputStream in = methodThatYouWriteYourselfCalledgetInputStreamForURI("http://www.domain.com/test.xml");
Document doc = docBuilder.parse (in);cheers,

How to include header files from different directories?

Hi,
Sorry for the newb question, but I can't figure this out. I'm trying to compile a simple piece of code (C++) that uses header files in a directory different from the Project directory; header files are in /opt/csw/postgresql/include/pqxx. I've tried a few different things, adding that directory to the include directives under Resource Files, add existing files from a folder, etc etc. Whenever I try to build, dmake bails with status -1. I can't seem to get this working, can someone explain how to use header files from different directories?
Thanks,
SlowToady

Header files are usually specified relative to a base directory. If the base directory is not a system directory -- /usr/include or the compiler installation directory -- add a command-line directive
-I path/to/base/dirfor each such directory.
The path can be absolute, such as
-i /opt/csw/postgresql/includeor relative, such as
-I ../../my/includeIn your source code, specify the header file relative to the base directory, and be sure to use quotes, not angle brackets. Example:
#include "header.h" // right
#include <header.h> // wrongThe angle brackets are used for system headers, like <iostream> or <stdlib.h>.
The rules above are common to all compilers on Unix and Linux, and generally to all C and C++ compilers.
For more details, read about the -I option in the C++ Users Guide. You can find the guide by pointing your browser to the "docs" directory in the compiler installation, or go here:
http://docs.sun.com/app/docs/doc/819-5267
All command-line options are described in Appendix A.

Java receive files from different station ??

Hi,
I would like that a station can receive files from different stations in the same time.
For that, I use multi-threading (with different socket TCP). I have just a problem, sometimes files received are empty or contains just the last line of file. I don't know why, I saw all datagrams on the network but at reception sometimes it reads just the end.
The class to receive file functions when it receives just one file, but when files comes at the same time there are some problem.
Is there a problem of thread ? (I start a thread but I don't know where stop it) or a problem in my class for receive file:
For sending a file:
while((len = fis.read(buffer,0,1024))!= -1)
os.write(buffer, 0, len);
new LogFile().writeLogFileError
For receiveing file:
while((len = is.read(buffer,0,1024))>=0)
fos.write(buffer, 0, len);
//when theres a problem, I receive -1 the first time, but I am sure data are sent to this station
Is someone had same problem ?
Thank you
Maryline

Maryline,
its probably a better idea to use Stream Sockets, as opposed to datagrams, as the datagrams can be delivered in any order (hence end of file so soon possibly).
On the Server Station do the following:
import java.net.*;
import java.io.*;
private final int SERVER_PORT = 4567;
private final int SERVER_BACKLOG = 100
ServerSocket server = new ServerSocket( SERVER_PORT, SERVER_BACKLOG );
while (true) {
Socket s = server.accept();
//Start a new thread and pass the Socket s to it.
}You also need to create ObjectInputStreams and ObjectOutputStreams to read and write the data
ObjectInputStream input = new ObjectInputStream( s.getInputStream() );
ObjectOutputStream output = new ObjectOutputStream( s.getOutputStream() );
output.flush();On the client, you use
Socket s = new Socket( SERVER_MACHINE_NAME, SERVER_PORT )
ObjectOutputStream output = new ObjectOutputStream( s.getOutputStream
output.flush();
ObjectInputStream input = new ObjectInputStream( s.getInputStream() );
() );You can then use
output.writeObject( ANY_SERIALIZABLE_JAVA_OBJECT );to send the object, and
JAVA_OBJECT_TYPE myObject = (JAVA_OBJECT_TYPE) input.readObject();to recieve the object.
If its text data, you could read the data into a string field and send it
I hope this gives you some ideas to hepl towards your solution

How to access Excel files from different locations?

Hello,
I have successfully tested the Excel sample on WLS 7, and trying to run it on
the WLS 8.1.
Anyways, the common question for both is, how to access an excel files from different
locations (e.g. c:\path\1.xls, \\domain1\finance\fin.xls, \\domain1\marketing\customer.xls,
\\domain2\accounts\vouchers.xls)?
From example i can see that it picks from a specific path under repository.
Thanks
Ashok Gupta

The custom function sets the MS-Excel default directory to System.getProperty("user.dir")+"/excel"
(the domain directory), then opens the filename passed as a parameter. I assume
that if you pass in the fully specified path for the excel file ( like d:\MyDir\data\test.xls),
that it would open that file.

I did a backup from all my files saved in old external hd to time capsule. After that double checked and recover one file from TC to mac air and it worked just perfect. Today went through TC to recover another file and none of them were there?

It's good for that . . .
But also I don't keep all my stuff in my Mac.
But not for that.
This older and not day-by-day usage files I want to store in the time machine.
You can do that (see below), but how are you going to back them up? If your only copies are on the TC, when (not if) it fails, you risk losing your only copy of the data.
Is it possible to split TC in two partitions.
No, but there are some workarounds, including making a fixed-size disk image on it to "reserve" some space. See #Q3 in Using Time Machine with a Time Capsule.
But you still won't have backups of the stuff you put there.
You don't say what kind of Mac you have. If it's a desktop model, just keep the external HD connected to it, and let Time Machine back it up along with your internal HD.
However, it sounds like you may have a laptop, where that's not going to be convenient. In that case, your best bet might be to copy the external HD to a disk image on the TC as above, then keep the HD in a safe place.
To finish, when i enter the TC and go through the Time line how can I get a file from there and move it back to Mac hd.
Via the "Star Wars" display, per #15 in Time Machine - Frequently Asked Questions.
You might also want to review the Time Machine Tutorial, and perhaps browse the rest of the FAQ.

Printing different/selective files with different copies

Hi everyone,
I've been working on finding a solution, on how to print different pdf files with different copies, without opening the pdf-files.
Task:
I have a folder, with 25 pdf files
I want to make a php overview, of the folder
At the end of each line/file - i would like to add a number for the copies
In the end, I would like to simply press print - and every document ive added a number/copies to - are being printet...
I guess I need to use PrintPDF - but does anyone know any pre-made program/function - that could handle the "copies" part...?
I hope someone can help me out,
Thanks
Jan

Well, i had hoped that the acrobat could open silent - eventhough they've removed that feature in the newer versions.
Even though the program would open - if the amount of copies was added - and i just hat to press print - it would ease the job alot.

Read and List the Files from Remote Webserver Path

Hi All,
I have requirement where i need to Read and List the files from a Folder of Remote webserver path using JAVA.
Remote webserver is within the network only...No Firewall and also Access is given to Read the folder. No Issues on this.
Folder will just contain some PDF files...
I just need to display the PDF file names available in the Folder..
No need to read the PDF File...Only required to read the folder to list the file names in it.
Looking forward some workaround to this.
Thanks and Regards.

I need to read the folder from a webserver path of different machine...
File dir = new File( prop.getProperty("inputPath"));
File[] files = dir.listFiles(fileFilter);
final String match=siteName;
     final String type=reportType;
     Calendar c1 = Calendar.getInstance();
     c1.add(Calendar.MONTH, - Integer.parseInt(prop.getProperty("filterMonths"))); //Filters reportes generated in last X months (X picked from config file)
     final long filterDate = c1.getTime().getTime();
     FileFilter fileFilter = new FileFilter() {
     public boolean accept(File file) {
     long fileLastModiDate = file.lastModified();
     if((fileLastModiDate >= filterDate) && (file.getName().toLowerCase().startsWith(match)) && ( (type.equals("M") && file.getName().indexOf("WIP")==-1) || ((!type.equals("M") && file.getName().indexOf("WIP")!=-1)) ) ) {
          return true;
     }else {
          return false;
Here it works fine if the input path is local machine..
But i need to know how to give the input path as WEBSERVER PATH of different machine??

I have recently updated my CC programs to the latest version and now all of my files wont open by default into their respective programs, only if I open the program and go to file open and open the file from there. How can I fix this?

I have recently updated my CC programs to the latest version (CC2014) and now all of my files wont open by default into their respective programs, only if I open the program and go to file>open and open the file from there. How can I fix this?
I have tried 'Open with' and the version of the program now installed on my computer isn't even suggested as an option and when I browse for it, the file wont open with it anyway

On Windows (don't know about Mac), the latest version will always take over the file association, and become the default for indd files. It's impossible to change it.
But there is a plugin for ID that makes this possible. Never tried it myself.

I bought a new laptop and used Windows Easy Transfer cable and moved all files from one computer to another. I installed iTunes and found my iTunes music Library. However, when I plug in my iPod it says it is already synced with another iTunes Library.

I bought a new laptop and used Windows Easy Transfer cable and moved all files from one computer to another. I installed iTunes and found my iTunes music Library. However, when I plug in my iPod it says it is already synced with another iTunes Library.
I don't see anything in Help that shows when you already have transfered all the files over. Why would it want to erase and sync when I already have all the music folder copied over? I didn't have an issue when I had another technician copy from one laptop to another. Home sharing is also on but not being recognized.

I suspect you only migrated the media folder instead of the complete working library. Either review the transfer process and copy over the entire iTunes folder from your old profile's music folder or see Recovering your iTunes library from your iPod or iOS device.

Multiple jar files from different locations

Hello,
I am having an applet that access code from two different jar files. Of them one is a common jar file for many applets. So I couldn't place it in the local dir as that of the applet's html. I am not using any web server.
 Just to give you a feel of it :
 <PARAM NAME = archive VALUE = "DVApplet.jar,DVVP.jar" > are the jar files my applet is dependant on. But DVVP.jar has to be accessed from a dir different from local dir.
 Will be glad if someone can throw some light on accessing different jar files from different dirs.
 Thanks for your time.

I want to take files from my PC (using a Seagate external hard drive) then plug this Seagate External hard drive into my Mac Book Pro and move the files from the Seagate External Hard drive onto my Time Capsule. I do not want to put these files on my Mac. How do I do this? Where do I put these files on my Time Capsule? Will it affect the functioning of my Time Capsule?

Mixing files with data is not always great idea.
See info here.
Q3 http://pondini.org/TM/Time_Capsule.html
Why not just connect the PC directly to the TC by ethernet and copy the files over?
It is hugely faster and much less mucking around.
In windows load the airport utility for windows.. if you have not already as this will help you access the drive.
There is more info here.

I just downloaded the new version of iTunes 10 and now it won't let me drag and drop any files from my computer into my iTunes. It lets me play the song from the folder in my computer and then it opens with iTunes and plays the song all the way through, but then if I try to play it again, it says the file cannot be located. So then I go to locate and go to the folder and all that and select it and nothing happens.

Not sure whether for instance you initially had a Yahoo optimised version of Firefox, and have now overwritten it with an official Mozilla version. Although the Mozilla version should NOT add unwanted features, but the Yahoo version may well do.
If you merely need to find the Yahoo emails page quickly just add it as a bookmark or as a bookmark on the Bookmarks toolbar and make sure that is visible.
Clicking the star icon on the location bar whilst looking at your emails will bookmark the page.
