Appserver Active Clients

Posted by Carlos Vázquez on 16-Nov-2017 10:29

Hi, I am using OE11.63, over AIX plataform, we have a appserver with a lot of request, but our problem is "Active Clients"

We see that the number of clients is growing as the day progresses until it reaches its maximum and blocks the service.

The current value for maximum clients is 1024, and I don´t want to keep growing it.

There is a way to free the appserver? this is a programming issue?

Hi Carlos,
 
If you don’t actually have that many physical users then this is most likely an application coding issue where the code is not disconnecting from the appserver and/or the client is not deleting persistent procedures it ran on the appserver.

Hi Brian, thanks for your  answer, but, apart of  

h_app:disconnect()

delete object h_app.

There is any thing else to do it?

Regards

You are running stateless operating mode.  Check any program that runs something on this appserver and ensure that you disconnect (like you are doing) and also you do a delete procedure <blah> against any procedure you ran persistently on the appserver from the client, for example...
 
run bubba.p on server hAppServer persistent set hProc.

We don´t run any persistent programs.  This appserver is the back end for a REST application, have a lot of calls, but shorts ones.

Running  the same  programs all day long, but as the number of request grow, fail to free the client.

Here is a example of code that we are using.

   114     CREATE SERVER h_app.

   115     msino = h_app:CONNECT ("-AppService soiw -S 5162 -H " +

   115     mServer) NO-ERROR.

   116

   117   1     IF NOT msino THEN DO:

   118   1         CREATE estatus.

   119   1         estatus.codigo  = "500".

   120   1         estatus.mensaje = "Sin conexion para crear Venta".

   121   1         RETURN.

   122         END.

   123

   124         RUN soi/crea_t_pagos_3.p ON h_app ( TABLE sesion,

   125                                             ticket.origen,

   126                                             ticket.ticket,

   127                                             INPUT TABLE pago,

   128                                             INPUT TABLE opcionales,

   129                                             OUTPUT TABLE venta,

   130                                             OUTPUT TABLE estatus

   131                                           ).

   132

   133     h_app:DISCONNECT ().

   134     DELETE OBJECT h_app.

Carlos,
 
If that is all the code does then I don’t have an answer.  Please open a support case so we can investigate this in more detail.
 
Thanks, Brian

Thanks Brian, I already did it. But I am looking everywhere for help...Some times over here is faster than support..

Hello Carlos,

at line 121 you leave your program without deleting object h_app.

The persistent procedure does still persistently on the appserver from the client.

I think that, if you delete object h_pp before the RETURN, your problem maybe is solved.

Kind regards,

Richard Zwart

I agree with [mention:6a07d624f4174b7395501c64e5a45da8:e9ed411860ed4f2ba0265705b8793d05] and adding to what he suggested. Delete "object h_app" inside the FINALLY block. This will make sure that object is deleted even when there are abrupt/unhandled exceptions in the code.
