[Monetdb-developers] problems with starting the monetDB4 xquery server
by Mtekel 04 Jun '09

04 Jun '09

Hello, I have problems starting the monetDB xquery server under windowsXP sp3. When I click on the link in the start menu, dos window appears but then it closes immediatelly and I can't see what's there (after pausing I can see only the first 6 lines of the program output as described below, then after unpausing it immediatelly quits and closes the window). If I run MXQserver.bat, or Mserver.bat --dbinit="module(pathfinder);" I get only this: # MonetDB Server v4.28.4 # based on GDK v1.28.4 # Copyright (c) 1993-July 2008, CWI. All rights reserved. # Copyright (c) August 2008-2009, MonetDB B.V.. All rights reserved. # Compiled for i686-pc-win32/32bit with 32bit OIDs; dynamically linked. # Visit http://monetdb.cwi.nl/ for further information. # PF/Tijah module v0.9.0 loaded. http://dbappl.cs.utwente.nl/pftijah That's all. The server immediatelly ends. However If I run only Mserver.bat, the server "runs" - I get the prompt, but for example I can't connect to the web interface on the port 50000. Does anyone have any advice what to do? How to make it work? Any advice appreciated, Best regards Michael

The MonetDB team at CWI/MonetDB BV are pleased to announce the new "May2009" feature release of the MonetDB suite of programs. This is a feature release, however it is is (mostly) backward compatible with the previous releases (Nov2008 and Feb2009). The two slight incompatibilities are: - The way string data is stored was changed for 64-bit architectures with 32-bit OIDs. There is however an automatic conversion on startup of the server. The biggest problem is, you can't go back to an older version once the new version has run. This incompatibility affects only the Windows 64 bit build (the other 64 bit builds use 64-bit OIDs). - The default location of the write-ahead log (WAL) has changed. This is relevant for both MonetDB5/SQL and MonetDB4/XQuery on all platforms. When the server first starts on an existing database, it will notice that the WAL is missing and will refuse to continue with a message which indicates where the WAL is now expected. You can either use a command line option to tell the server where the WAL is, or you can manually move the WAL to the new location. This latter option is done automatically on Windows when you use the Start menu to start the server. More information on the new release (and the above mentioned incompatibilities) is available at <http://monetdb.cwi.nl/projects/monetdb/Development/Releases/May2009/>. The sources and binaries are available at <http://monetdb.cwi.nl/projects/monetdb/Download/>. -- Sjoerd Mullender

[Monetdb-developers] mclient mem-usage during --dump
by Wouter Alink 28 May '09

Hello, Question: is there any reason for mclient to use (large) amounts of memory during a dump of a sql database? syntax used: $ mclient -lsql -D -dsomedatabase > dump.sql I observe >12 GB of resident memory use when dumping a 2GB (in dump text format) database (it steadily grows), using the May2009 stable branch (of last week) Top shows: 28371 walink 16 0 12.2g 12g 2944 R 87 4.0 10:48.58 mclient I haven't investigated it any further, but I was first of all wondering whether it actually needs these amounts of memory? Greetings, Wouter
