  • Got a minus one from a read call.

    - by sunyata
    I connect to a database with read only access using SQL developer. It's a TNS connection. I use a tnsnames.ora, forwarding port script and SQL Developer. In the past, occasionally, when connecting, I get a error message Got a minus one from a read call. Vendor Code 0 If I do a reboot, it goes away. Another friend suggested changed the forwarding port which worked for him. I recently upgraded to a new computer and now it seems that I am getting the error message consistently. Reboot or changing forwarding port does not help at all. The port forwarding script contains something like this putty -L ::1521 Does anybody have any idea? Thanks.

  • How can I set up a fault-tolerant web-service built with Erlang/OTP?

    - by Jonas
    I would like to setup a fault-tolerant web-service. I will build the web-service with Erlang/OTP. At the beginning the web-service will be hosted on a few VPS. Each VPS has its own IP-address, and I can use more if IPs if I need. I would like to have the domain name pointing to a single IP-address. How can setup my Erlang/OTP-application to be fault-tolerant behind a single IP-address? Do I need to use VLAN? Is there a way my Erlang/OTP-application can use heartbeats and handle virtual IP-addresses to route the traffic? or how should I solve this problem?

  • PHP voting system with sessions?

    - by pingu
    Hi guys, I've been reading up on stackoverflow about creating voting systems in PHP that minimize abuse/multiple voting from the same user, but I haven't come across the answer to my question. I've got an application where users don't need to register to vote or "like" an entry. Obviously, I want to minimize abuse and I don't want to limit votes per IP address because some organisations (mine included) use shared IP addresses. I've never used sessions in a non-authenticated system before, but since this application is centered around entry votes I was wondering if this approach would work and whether there were any disadvantages such as performance implications, and whether it's even possible to use sessions in this way: start a session when the website is loaded allow one vote per item per session If this is a bad idea, my alternative options would be to allow a reasonable number of votes per IP address (say 25), or put a time limit between votes from the same IP address. What do you guys recommend?

    - by Sanjay Sen
    I have a JSONP WCF service,using back end as MySql.It is working properly when i run it locally with visual studio. Now we have hosted it in Windows Server 2003. Now there is very strange problem occurring.. When I do a request with fiddler which does not require much processing internally, it gives me result 200 OK with desired output as response, But when I do a request which requires some internal data processing, it gives me 504 error(gateway time out error). I also looked at C:\WINDOWS\system32\LogFiles to see if it logs any error but it shows ok result in fiddler request which is as follows: Fields: date time s-sitename s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status 2010-04-07 10:08:06 W3SVC490896353 s-ip GET /InitialState.svc/GetInitialState reference=1&pageId=18 8080 - c-ip Fiddler 200 0 64 Can anyone please help me to resolve the problem ??

  • Java ServerSocket Multiple Listen Instances

    - by ikurtz
    i have a java game app that uses sockets to communicate with each other. the issue is when i do a socket listen (server), i can run another instance of the game on the same machine using the same port as before to listen, and it results in listening again. now i have two instances of the application both listening on the same port. you can imagine only one connects when a connection comes through. the question is: how do i prevent the app from listening on the same port as another instance is already listening to? thanks in advance. EDIT: serverSocket = new ServerSocket(serverPort, backlog); im using this. should i try to use: ServerSocket(int port, int backlog, InetAddress bindAddr) instead? EDIT: SOLVED! i did not handle the exception only trapped it. now it is working well. thanks for your inputs.

    - by trybeingarun
    Hi, I installed cedet successfully today and got most of it working; thanks to Alex Ott's Gentle Introduction to Cedet. However i am having a problem When I give the exact path relative to the current file i am working on then auto-completion is working fine. #include "../../opensource/inc/lldp_port.h" void test_func() { lldp_port port; port.blah //here auto-completion worked fine } However i cannot specify the full path all the time( we have eclipse at office and it generates makefiles for us ) #include "lldp_port.h" void test_func() { lldp_port port; port. //here auto-completion does not work :( } What should i do to solve this?

  • Save File to Sharepoint Server using JAX-WS

    - by Evan Porter
    I'm trying to save a file to a Sharepoint server using JAX-WS. The web service call is reporting a success, but the file doesn't show up. I used this command (from a WinXP) to generate the Java code to make the JAX-WS call: wsimport -keep -extension -Xnocompile http://hostname/sites/teamname/_vti_bin/Copy.asmx?WSDL I get a handle on the web service which I called port using the following: CopySoap port = null; if (userName != null && password != null) { Copy service = new Copy(); port = service.getCopySoap(); ((BindingProvider) port).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, userName); ((BindingProvider) port).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, password); } else { throw new Exception("Holy Frijolé! Null userName and/or password!"); } I called the web service using the following: port.copyIntoItems(sourceUrl, destUrlCollection, fields , "Contents of the file".getBytes(), copyIntoItemsResult, copyResultCollection) The sourceUrl and the only url in destUrlCollection equals "hostname/sites/teamname/Tech Docs/Sub Folder". The FieldInformationCollection object named fields contains only one FieldInformation. The FieldInformation object has "HelloWorld.txt" as the value for displayName, internalName and value. The type property is set to FieldType.FILE. The id property is set to (java.util.UUID.randomUUID()).toString(). The call to copyIntoItems returns successfuly; copyIntoItemsResult contains a value of 0 and the only CopyResult object set in copyResultCollection has an error code of "SUCCESS" with a null error message. When I look into the "Tech Docs" library on Sharepoint, in the "Sub Folder" there's no file there. Why wouldn't it tell me what I did wrong? Did I just miss a step? Update (Feb 26th, 2011) I've changed my FieldInformation object's displayName and internalName properties to be "Title" as suggested. Still no joy, but a step in the right direction. After playing around with the urls for a bit, I got these results: With both the sourceUrl and the only destination URL equivalent, with no protocol, I get the SUCCESS response but no actual document appears in the document library. With both of the URLs equivalent but with an "http://" protocol specified, I get an UNKNOWN error with "Object reference not set to an instance of an object." as the message. With the source URL an empty string or null, I get an UNKNOWN error with " Value does not fall within the expected range." as the error message.

  • Best way to install multiple versions of Apache, PHP and MySQL on a single FreeBSD host

    - by Mikael Roos
    I want a test- and development-environment for web using Apache, PHP and MySQL. I need to be able to test a single web-application with multiple versions of PHP (5.2, 5.3, etc) and multiple versions of MySQL (5.0, 5.1, 5.5, etc). It shall be hosted on a FreeBSD server. My idea is to compile each version into a directory structure and running them on separate portnumbers. For example: opt/apache2.2-php5.2-mysql-5.0 (httpd on port 8801, mysql on port 8802) (directory contains each software, compiled and linked towards eachother) opt/apache2.2-php5.3-mysql-5.1 (httpd on port 8803, mysql on port 8804) (and so on) Any thoughts or suggestions of the best way to setup this type of environment?

  • Multiple, Simultaneous Factories and Protocols in Twisted: Same Service, Different Ports

    - by RichardCroasher
    Greetings, Forum. I'm working on a program in Python that uses Twisted to manage networking. The basis of this program is a TCP service that is to listen for connections on multiple ports. However, instead of using one Twisted factory to handle a protocol object for each port, I am trying to use a separate factory for each port. The reason for this is to force a separation among the groups of clients connecting to the different ports. Unfortunately, it appears that this architecture isn't quite working: clients that connect to one port appear to be available among all the factories (e.g., the protocol class used by each factory includes a 'self.factory.clients.append (self)' statement...instead of adding a given client to just the factory for a particular port, the client is added to all factories), and whenever I shutdown service on one port the listeners on all ports also stop. I've been working with Twisted for a short while, and fear I simply don't fully understand how its factory classes are managed. My question is: is it simply not possible to have multiple, simultaneous instances of the same factory and same protocol in use across different ports (without these instances stepping on each other's toes)?

  • RHEL Cluster FAIL after changing time on system

    - by Eugene S
    I've encountered a strange issue. I had to change the time on my Linux RHEL cluster system. I've done it using the following command from the root user: date +%T -s "10:13:13" After doing this, some message appeared relating to <emerg> #1: Quorum Dissolved however I didn't capture it completely. In order to investigate the issue I looked at /var/log/messages and I've discovered the following: Mar 22 16:40:42 hsmsc50sfe1a openais[25715]: [TOTEM] entering GATHER state from 0.

  • Transforming a string to a valid PDO_MYSQL DSN

    - by Alix Axel
    What is the most concise way to transform a string in the following format: mysql:[/[/]][user[:pass]@]host[:port]/db[/] Into a usuable PDO connection/instance (using the PDO_MYSQL DSN), some possible examples: $conn = new PDO('mysql:host=host;dbname=db'); $conn = new PDO('mysql:host=host;port=3307;dbname=db'); $conn = new PDO('mysql:host=host;port=3307;dbname=db', 'user'); $conn = new PDO('mysql:host=host;port=3307;dbname=db', 'user', 'pass'); I've been trying some regular expressions (preg_[match|split|replace]) but they either don't work or are too complex, my gut tells me this is not the way to go but nothing else comes to my mind. Any suggestions?

  • Need help with displaying the message correctly in the pole display

    - by SA
    Hi, I am using an HP RS232 pole display with the following setting: Char type: USA/Europe (default) Command mode: EPSON (default) Baud rate: 9600, n , 8, 1 (default?) Passthru None (Default) Here's the code using System.IO.Ports; private SerialPort port; port = new SerialPort("COM2", 9600, Parity.None, 8, StopBits.One); port.Handshake = Handshake.None; Port.WriteLine("Welocome to something something"); It has 2 lines consisting of 20 characters each with a total of 40 characters. I have no control how and where the characters get displayed. I have set it to accept ASCII char set and so I am able to type as is visble in the Writeline message

  • GPIB connection to external device using MATLAB

    - by hkf
    Is there a way to establish a GPIB connection using MATLAB without the instrument control Tool box? (I don't have it). Also is there a way for MATLAB to know what the external device's RS232 parameter values are ( Baud rate, stop bit etc..). For the RS232 connection I have the following code: % This function is meant to send commands to Potentiostat Model 263A. % A run includes turning the cell on, reading current for time t1, turning % the cell off, waiting for time t2. % t1 is the duration [secs] for which the Potentiostat must run (cell is on) % t2 is the duration [secs] to on after off % n is the number of runs % port is the serial port name such as COM1 function [s] = Potentiostat_control(t1,t2,n) port = input('type port name such as COM1', 's') s = serial(port); set(s,'BaudRate', 9600, 'DataBits', 8, 'Parity', 'even', 'StopBits', 2 ,'Terminator', 'CR/LF'); fopen(s) %fprintf(s,'RS232?') disp(['Total runs requested = ' num2str(n)]) disp('i denotes number of runs executed so far..'); for i=1:n i %data1 = query(s, '*IDN?') fprintf(s,'%s','CELL 1'); % sends the command 'CELL 1' %fprintf(s,'%s','READI'); pause(t1); fprintf(s,'%s','CELL 0'); %fprintf(s,'%s','CLEAR'); pause(t2); end fclose(s)

  • mysql query: SELECT DISTINCT column1, GROUP BY column2

    - by Adam
    Right now I have the following query: SELECT name, COUNT(name), time, price, ip, SUM(price) FROM tablename WHERE time >= $yesterday AND time <$today GROUP BY name And what I'd like to do is add a DISTINCT by column 'ip', i.e. SELECT DISTINCT ip FROM tablename So my final output would be all the columns, from all the rows that where time is today, grouped by name (with name count for each repeating name) and no duplicate ip addresses. What should my query look like? (or alternatively, how can I add the missing filter to the output with php)? Thanks in advance.

  • How does Windows Remote Desktop Connection Work?

    - by Devoted
    How does Windows Remote Desktop connection work? An IP address is used to connect to the computer but....how can that IP be accessed from anywhere? If, for example, the IP address is 192.168.1.55, there MUST be another 192.168.1.55 somewhere else in the world. How does Remote Desktop know which one to connect to? Thanks so much
