Always On: Detect from client which replica is active

Since the client simply connects to the listener and gets an IP, is there a way through either the client object model or a query which I can use from the client to determine which replica is on the other end of the connection?
Thanks,
Philo

Hello,
If you just want to know which replica you are on, you can check @@ServerName, if the replica can be hosted on a FCI then you'll want to check the node's physical name through SERVERPROPERTY('ComputerNamePhysicalNetBIOS').
Is this what you're after?

Sending an object from client to server always on button press

What I need is to send an object from client to server but I need to make server wait until another object is sent. What I have is the JFrame where you put the wanted name and surname, then you create a User object with these details and on button press you send this object to the server. I just can't hold the connection because when I send the first object, server doesn't wait for another button click and throws EOFexception. Creating the while loop isn't helpfull as well because it keeps sending the same object again and again. The code is here
public class ClientFrame extends JFrame {
    private JButton btnSend;
    private JTextField txfName;
    private JTextField txfSurname;
    public ClientFrame() {
        this.setTitle(".. ");
        Container con = this.getContentPane();
        con.setLayout(new BorderLayout());

Current code fails because it's sending still the same entity again(using while loop)No it's not. You are creating a new User object every time around the loop.
which makes the system freezeWhich means that you are executing network code in the event thread. Don't do that, use a separate thread. At the moment you're doing all that sending inside the constructor for ClientFrame which is an even worse idea: you can never get out of there to the rest of your client program. This is a program design problem, not a networking problem.
and doesn't allow me to set new parameters of the new entityI do not understand.
I need to find a way to keep Server running even when the client doesn't send any data and wait until the client doesnt press the send button again to read a new object.That's exactly what happens. readObject() blocks until data is received.

I have Photoshop CS5, and use windows XP. I cannot open bridge from photoshop, which I have done for years. When I am in Photoshop, when it opens, I always click on the bridge icon at the bottom of the screen and it puts me into bridge. This is not happening, the small wheel at the bottom of the screen just keeps spinning. Its like its stuck or caught in a loop. I can't get into bridge. I tried shutting down and starting up again but the problem remains. Looking for help. Dan

Thanks for your response, I was able to open bridge from File-Browse in Bridge. This worked, but was not able to go back to the way I always opened Bridge. At least I could get to Bridge and go into Camera Raw. I never tried to open Bridge from the Start menu. The odd thing about this is, it has happened before, and to get it "unstuck" and working again, I would shut down and restart again in a few minutes, and things would go back to normal. This time it did not go back to normal after several attempts. I shut down for about 3-4 hours, restarted, and it seems to be back to normal again. I am not sure if it's a problem that is getting worse each time it happens. And yes I am using Mini Bridge in photoshop CS5. Thank you for your help. Dan

I was having an issue opening a spreadsheet with the file extension .xlsm. This appears as an attachment from a client which means macros were utilized when creating the spreadsheet. The problem lies in. The iPads ability to open the attachment. I downloaded the numbers app thinking this would be a default software to open any and all spreadsheets.
Please Help!
Ipad 2- iOS5

You may need a version without macros on it. Unfortunately, pretty much all apps are skinned down versions of their original program, often with less functionality. For example in a word document I can italicize,bold and underline, but I only have a handful of fonts to play with and I don't think I can insert tables or images.
It is very possible that the app simply cannot run macros, which means that document may never work on an iPad.

How long CSS blocks flow, from source which detected as source DoS?

My application generates except normal flow, flow which CSS treats as DoS attack. Both flows have the same source.
I am afraid that, CSS can block proper flow.
So, I have question: how long CSS blocks flow, from source which detected as source DoS?
Krzysztof

I am not very sure of the lenghth of time that it blocks the flow from the source, if it is considered as a source of DoS attack, but the workaround would be to bypass the cache for that particular source, since you are already aware that it might cause a problem. You could use a bypass rule to do so. You can also use the flow timeout feature with the flow port[1|2|3|4|5|6|7|8|9|10] timeout command to configure a flow timeout value for a TCP or UDP port. I am not very sure if this feature would help in your situation, bypass seems to be a better option.

Home directory is not created and cannot log from client computer

I am trying to set up MacOsX server. I already have another server which is my DNS server. I am trying to create an Open Directory Master server.
Server was updated to 10.4.8 MacOsX from the beginning of existence.
I created couple of users in Open directory domain for testing purposes.
So, the first problem is, that when I am trying to create a user home directory server does not create it and does not give any errors about that. I tried in bash createhomedir utility, it did not work either, again, no error messages.
Another problem:
I set up Open Directory master with LDAP. It was set up correctly, no error messages. At least I did not see any.
The I tried to connect to the server from my client iMac computer which has 10.4.8 MacOsX as well. So I set up LDAP there in Directory services, it was able to find my server and bind to it. Then when I am trying to login with username and password in Open Directory on the server, it does nor recognize it. No error messages in logs as well.
However, if I am trying to use ssh from client machine to connect to Server using the names which are in Open Directory on the server it allows me to do so. But of course it says no home directory defined.
Than you very much for responce!

An Open Directory Master requires DNS running somewhere. You could have a scenario involving 4 servers where: DNS is provided by Server A, Server B is a Web & Mail Server, Server C providing FTP Services and Server D providing LDAP services with managed preferences and automounting Home Directories (ODM). In this scenario DNS is provide by Server A and any other server requiring DNS using Server A’s DNS. You could expand this scenario if you wanted and have replica (fallover) servers for Servers A, B C or D, or if you are the frugal sort just one replica server replicating the 4 primary servers. You can do all of this pretty much in 10.4 GUI with some additional configuration using Terminal
Mac OS X (10.4.8)

Date converting to less one day while transferring from client to server

Hi,
I have very typical problem. My application is in java, we are using oralce 9ias. The problem when the server is running in german locale and client is running in english. We the date value is passed from client to server it is converting to one day less.
i.e.
If i want to search with records jan 02,2005,
on server side if we print the value it is getting as jan 01,2005.
Can anybody help me in solving the above problem.
Its bit very urgent.
Thanks in advance
regards
Kalyan

well, i have had nightmares with this problem. here are the reason and soln:
reason:
in ur DB, u r using a field "Date" which does not include time information. Hence, any date will be taken at 00:00:00. If such a date is opened in some other timezone, which is ahead of the server timezone, the date differs by one. This is becoz java always considers the millisecond info encapsulated in the date, calendar.
soln:
Step 1:
u must be able to get the "timeZoneOffset" from a calendar object. This timeZoneOffset will give the number of minutes/seconds/hours... by which the system is offset from GMT.
Thus if u create a calendar in India, the timeZoneOffset will be 330. If you create the calendar in UK, it will be 0.
To achieve this, we have made an object-UTCDate. This class encapsulates a Calendar. It has a function called "getTimeZoneOffset".
Step 2:
Once u get the timeZoneOffset, here is what u need to do in ur code. (assume that the timeZoneOffset is in minutes. the variable names will be self-explanatory)
at the client side code:
long timeInMillis = calendar.getTime().getTime() + (timeZoneOffsetOfTheCalendarReceivedFromServer * 60 * 1000 ) - (timeZoneOffsetOfClient * 60 * 60 )
use timeInMillis to make a new Date Object and use this date object.
at the server side code:
long timeInMillis = calendar.getTime().getTime() + (timeZoneOffsetOfTheCalendarReceivedFromClient * 60 * 1000 ) - (timeZoneOffsetOfServer * 60 * 60 )
hope this helps.

New User M.Senthil..

Hi,
Well,i don't know whether if this helps people here are not.
It is always a good practise to do it via Servlet and then download content.
The adavantage of doing this is
1). You may not need to pack the downloadable with the .war which you ultimately genrate which ceratinly help us in terms of faster deployment.
3). You may update the new content just by moving a file to the backup folder.
2).One may definately download the content irrespective to the content/file.
Hope example below helps..
Configurations:
In the above example we are assuming that we placing all downlodable file in D:/webapp/downlodables/ and you have configured the same path as a init param with the name "filePath" in your web.xml.
something like the one below.
<servlet>
    <servlet-name>DownloadServlet</servlet-name>
    <servlet-class>com.DownloadServlet</servlet-class>
    <init-param>
       <param-name>filePath</param-name>
       <param-value>D:/webapp/downlodables/</param-name>
       
    </init-param>

Do you really mean "Delete DC" or do you mean "Remove from client"?
A Remove from client just removes the DC from your local system, while a Delete DC removes the DC from the DTR!
In case you really want to delete the DC from the DTR, try just syncing the sources <b>without</b> performing a build.

Copy file from client PC to server in a web deployed application

I have developed one application using Oracle forms 6i, which is deployed on the web server.
I run this application from a client PC in Internet Explorer using internet.
I want to copy one file from the client PC to the web server.
I have done following things
- Created a shared folder on the server and given full rights to every one on this folder
- I use 'net use' command in my program to connect to this shared folder
- I use copy command to copy file from local client pc to server. This copy command I am executing using host command of my programming (PL/SQL: eg. host('copy abc.txt \\server\share\') )
But this does not work.
When I do the same thing in command window, it works.
(ie. Start-Run cmd to open command window and then type the above copy command)
Can you please tell me, how to copy a file from client PC to the sever in Web deployed application?
Thanks

I downloaded D2KWUtil from the link suggested by you. It has very nice example demo form. But the documentation provided says following
Using D2KWUTIL in Web Deployed Applications
The use of this library is not supported with Web deployed applications.
In a web deployment scenario not all functions within D2KWUTIL will work. Any function that interacts with the User Interface (such as those in the WIN_API_DIALOG package) will fail.
Any interaction with the O/S by other functions will all be executed on the NT server and will act within, or return information pertinant to, the environment on that machine. For instance GET_COMPUTER_NAME will return the Server’s name, not the name of the computer that the Client browser is running on. Likewise COPY_FILE will copy files in the Forms Server not on the Client.
Functions such as those in WIN_API_BITOP will continue to work without change.
so this will not work in web deployed application.
Any other suggestion?
Thanks

To upload a file from client machine to server machine

Hi everybody!

How to find out a file from client machine

hi all,
I want to read a file from client machine, like a outlook express file in which all the address are saved, using servlet. Initially i do not know the file path for that file, How i can read that file.
plz help me
thanx in advace
Manish

You have 2 possibilities. First, you might be able to mount the client's disk drive at the server; the servlet can then access that drive directly. Second, install a client program on the client machine and communicate with that program, and have it do the search (or whatever).
Outside of Java, there are remote-access programs - like PCAnyWhere.

How can i load file into database from client-side to server-side

i want to upload file from client-side to server-side, i use the following code to load blob into database.
if the file is in the server-side, it can work, but if it in the client-side, it said that the system cannot find the file. i think it only will search the file is in the server-side or not, it will not search the client-side.
how can i solve it without upload the file to the server first, then load it into database??
try
ResultSet rset = null;
PreparedStatement pstmt =
conn.prepareStatement ("insert into docs values (? , EMPTY_BLOB())");
pstmt.setInt (1, docId);
pstmt.execute ();
// Open the destination blob:
pstmt.setInt (1, docId);
rset = pstmt.executeQuery (
"SELECT content FROM docs WHERE id = ? FOR UPDATE");
BLOB dest_lob = null;
if (rset.next()) {
dest_lob = ((OracleResultSet)rset).getBLOB (1);
// Declare a file handler for the input file
File binaryFile = new File (fileName);
FileInputStream istream = new FileInputStream (binaryFile);
// Create an OutputStram object to write the BLOB as a stream
OutputStream ostream = dest_lob.getBinaryOutputStream();
// Create a tempory buffer
byte[] buffer = new byte[1024];
int length = 0;
// Use the read() method to read the file to the byte
// array buffer, then use the write() method to write it to
// the BLOB.
while ((length = istream.read(buffer)) != -1)
ostream.write(buffer, 0, length);
pstmt.close();
// Close all streams and file handles:
istream.close();
ostream.flush();
ostream.close();
//dest_lob.close();
// Commit the transaction:
conn.commit();
conn.close();
} catch (SQLException e) {

Hi,
Without some more details of the configuration, its difficult to know
what's happening here. For example, what do you mean by client side
and server side, and where are you running the upload Java application?
If you always run the application on the database server system, but can't
open the file on a different machine, then it sounds like a file protection
problem that isn't really connected with the database at all. That is to
say, if the new FileInputStream (binaryFile) statement fails, then its not
really a database problem, but a file protection issue. On the other hand,
I can't explain what's happening if you run the program on the same machine
as the document file (client machine), but you can't write the data to the
server, assuming the JDBC connection string is set correctly to connect to
the appropriate database server.
If you can provide some more information, we'll try to help.

Though you can initiate the binary from your client side but for the file creation, there is no other way but to store it on the server side. So your best bet would be to get some space free on the server side of yours.
