Hello partners

I had the following problem: I had installed Windows Server 2008 R2 Foundation in which administrative software is installed. This works with a Firdbird database handler.

Record that with that Windows license when you had a maximum connection of 25 users, the number 26 could not access the shared folders of the server or make the connection to the system. We change the server and place a standard Windows Server 2019 operating system and with this operating system I can exceed the number of users who visit the shared folders that are inside the server and the connections to the administrative system, but from there the issue of the users beginning to lose connection to the database and must reload the system so that they can read the database once the administrative system surpasses the 25 users.

Thank you all. Greetings.

 

 

 

Hola Compañeros.

Presento el siguiente problema: Tenia instalado Windows server 2008 R2 Foundation en el cual hay instalado un software administrativo. Este funciona con un manejador de bases de datos Firdbird.

Recordemos que con esa licencia de Windows cuando tenía un máximo de conexión 25 usuarios el número 26 no podía acceder ni las carpetas compartidas del servidor ni realizar conexión al sistema. Cambiamos el servidor y colocamos un sistema operativo Windows server 2019 standard y con este sistema operativo puedo superar la cantidad de usuarios que visitan las carpetas compartidas que se encuentran dentro del servidor y las conexiones al sistema administrativo, pero ahí viene el problema que los usuarios del sistema administrativo una vez superado los 25 usuarios comienzan a perder la conexión con la base de datos y deben volver a cargar el sistema para que pueda leer la base de datos.

Gracias a todos. Un saludo.

May want to ask here about support for Server 2019 and any limitations there might be.

Hi, I understand your redirection to firebird, but the question is this: Windows Server 2019 Standard, does it constantly refresh or clean user sessions?

Does this make users terminate the connection to the server?

Could this disconnect the database?

Could you make a delay in disconnecting users?

Could you choose the users to which you do not disconnect the session?

What happens when you reach the limit of connections on Windows Server, TCP / IP ports are closed too?@Dave Patrick 

 

 

Hola entiendo vuestro redireccionamiento a firebird, pero la pregunta es la siguiente: Windows Server 2019 Estándar, ¿refresca o limpia las sesiones de los usuarios constantemente?

¿esta hace de los usuarios finalicen la conexión con el servidor?

¿esto podría desconectar la base de datos?

¿Podría hacer un retardo en la desconexión de los usuarios?

¿Podría escoger los usuarios a los cuales no desconectar la sesión?

¿Qué pasa cuando llega al límite de conexiones en Windows Server, se cierran puertos TCP/IP también?@Dave Patrick 

Maybe you're asking about opportunistic locking?

https://support.microsoft.com/en-us/help/296264/configuring-opportunistic-locking-in-windows

 

As to max concurrent TCP connection in windows server should be something over 16 million. Firebird may have its own set of limitations, better to ask firebird experts about this.

 

 

 

Hi,
according to the answer by Microsoft Employee:
It depends on the edition, Web and Foundation editions have connection limits while Standard, Enterprise, and Datacenter do not.

Hola amigos. Gracias por vuestra colaboración y tiempo en ayudar a conseguir el problema presentado. Hemos encontrado la falla y vosotros teníais razón ya que el problema provenía de Firebird y no de Windows Server ya que los usuarios colocaban caracteres especiales tales como la cedilla “ç” y cuando se realizaba la consulta la base de datos se desconecta y los demás usuarios pierden la conexión. Los programadores del sistema están revisando como validar este carácter ya que es muy usado en Francia, Portugal u Cataluña.

 


Hello friends. Thank you for your collaboration and your time helping to solve the problem. We have found the fault and you were right since the problem came from Firebird and not from Windows Server. The users placed special characters such as the “ç” cedilla and when the query was made the database was disconnected and the other users lost connection. System programmers are cheking how to validate this character as it is widely used in France, Portugal or Catalonia.

@HotCakeX . @Dave Patrick 

Glad to hear, you're welcome.

 

 

You're welcome,
and Nice job finding out the cause of that problem!
