[Monetdb-developers] Question about remote connection to MonetDB
Hi: I am a starter of MonetDB.I encountered a problem about conneting a remote MoneDB server via ODBC.The problem is discribed as follows: Given that the MonetDB server is running on a host(10.20.30.1),and,the Application program is running on a host (10.20.30.2).The MonetDB version is the windows version.I have tried to connet the server through the ODBC connect string in my appliction program,but failed,by the way,I am ensure the connect string is correct. My question is: 1.Can MonetDB server be connected via ODBC driver from a remote Application Clinet? 2.If it is so,how can I connet the MonetDB server.Wether need I do some configuration in the configure file of the MonetDB server? Waiting for your suggestion!Thanks! best regards! Davy China -- View this message in context: http://www.nabble.com/Question-about-remote-connection-to-MonetDB-tf1950030....

You have to enable the server to listen to remote connections. This can be done by using: mapi_start(true); instead of just "mapi_start();". I hope this helps.
Thank you very much.I have added the parameters according your suggestion.But I stil can not connet to the server from another host client.Please help me. The conent of the MSQLserver are as follows: @echo off rem figure out the folder name set MONETDB=%~dp0 rem remove the final backslash from the path set MONETDB=%MONETDB:~0,-1% rem start the real server "%MONETDB%\Mserver.bat" --dbinit="module(sql_server); sql_server_start();mapi_start(true);" %* -- View this message in context: http://www.nabble.com/Question-about-remote-connection-to-MonetDB-tf1950030....

Could you try this? "%MONETDB%\Mserver.bat" --dbinit="module(sql_server); mapi_start(true); mapi_register(sql_frontend());" %*
:( I have tried to do that,but I got the following message: !01 ERROR: interpret: no matching MIL operator to 'sql_frontend()'. !01 ERROR: interpret_params: mapi_register(param 1): evaluation error. -- View this message in context: http://www.nabble.com/Question-about-remote-connection-to-MonetDB-tf1950030....

A question we should have asked before givin any answer: Which version of MonetDB and MonetDB/SQL are you using? Stefan

I use the windows version 4.10.2. by the way,why the MonetDB odbc driver cannot be configured as other odbc driver(eg.Postgresql,Ora,and so on).I mean that i can configure the connetion information via the odbc.(eg.the destnation hostname,database name,login name,password)? -- View this message in context: http://www.nabble.com/Question-about-remote-connection-to-MonetDB-tf1950030....

Background: given that your MSQLserver.bat says/uses "%MONETDB%\Mserver.bat" --dbinit="module(sql_server); sql_server_start(); mapi_start();" %* and not (yet) "%MONETDB%\Mserver.bat" --dbinit="module(sql_server); mapi_register(sql_frontend()); mapi_start();" %* and that your Mserver does not seem to know sql_frontend() (yet), suggests that you're using MonetDB 4.10.2 & MonetDB/SQL 2.10.2 (or older), right? You should consider upgrading to the latest release MonetDB 4.12.0 & MonetDB/SQL 2.12.0 cf. http://sourceforge.net/mailarchive/forum.php?thread_id=19514893&forum_id=42505 http://monetdb.cwi.nl/GetGoing/Download/index.html Stefan -- | Dr. Stefan Manegold | mailto:Stefan.Manegold@cwi.nl | | CWI, P.O.Box 94079 | http://www.cwi.nl/~manegold/ | | 1090 GB Amsterdam | Tel.: +31 (20) 592-4212 | | The Netherlands | Fax : +31 (20) 592-4312 |

you probably also what the MonetDB/SQL server to be open for remote connections, hence: "%MONETDB%\Mserver.bat" --dbinit="module(sql_server); sql_server_start(true); mapi_start(true);" %* ^^^^ ^^^^ Stefan
