  1. Hello, This is a Windows Server 2022 where MARS is running on as a Windows service. There is no nginx or similar application between, so MARS Windows service is directly accessed. Not a heavy server at all. It is less than 10 simultaneous users at most and on average there is a single client accessing the server. I do not have any access to the server and I am not given any. It is reported that MARS Windows service is responding ECONNRESET error after random days of usage. Sometimes it is a month sometimes it is 10 days. There are application log files. They all seem fine. Last request is served then service is shutdown and restarted. There is no errors or request not completed according to logs. Once it happens it is the same error if MARS Windows service is tested to be used from localhost. I never had any problem with MARS. I have similar installations on Windows Server 2019/2022 with more simultaneous users which are running for years. My internet searches didn't help me much. Any help is appreciated. Thanks & Regards, Ertan
  2. Hello, There are some chain requests triggered from clients. Some requests among them takes time processing on the server side. I should send a response to client fast. Server side operations are not relevant to the response. Since, MARS is handling each request in a separate thread, I also created a custom thread for this time consuming operation and process it. My problem is, database context is removed as soon as response is sent and its thread is destroyed. Any further database operations from that point in my custom thread results in access violation. Is there a way that I can get a database connection from MARS database pool for my own custom threads independent of requests? Thanks & Regards, Ertan
  3. Hello, MARS file serve samples are based on fixed static data (ContentTypes demo). I have several endpoints serving dynamic data in ZIP files. When upload finishes on the server side, remaining temporary files are kept on disk. This become a problem on server systems in time. I would like to learn if it is possible to have MARS delete them automatically at the end of the communication. I will write my own thread but asking before just in case. Thanks & Regards, Ertan
  4. Hello, I am trying to provide client library for FirebirdSQL database connection for a MARS-Server project. I tried a few different INI parameters, all failed including second line below FireDAC.MAIN_DB.DriverID=FB FireDAC.MAIN_DB.VendorLib="C:\Program Files\Firebird\Firebird_2_5\WOW64\fbclient.dll" FireDAC.MAIN_DB.Database=C:\Program Files\Firebird\Firebird_2_5\examples\empbuild\EMPLOYEE.FDB I wonder what I should be using to be able to use a fbclient.dll in another directory than the EXE file. Thanks & Regards, Ertan
  5. Hello, I have orders and orderdetails tables. There is one method that should be returning several orders when used. I would like to return a json string to such requests as in following example { "orders":[ { "id":1234, "date":"2020-05-29", "details":[ { "item":"1", "amount":3 }, { "item":"5", "amount":2 }, { "item":"116", "amount":1.3 } ] } ] } I know that I can define method to return a TJsonObject and build json piece by piece in method code. However, I would like to avoid that, if possible. I wonder if there is/are some other ways of doing so in MARS. Thanks & regards, Ertan
