... maybe instead of using different program(-name) suffixes (--program-suffix='-dsh') --- I'n not sure we ever tested that --- you could better use different installtion prefixes, say
--prefix=/home/bruder/monetdb-root-1 and --prefix=/home/bruder/monetdb-root-2
for different version of MonetDB?
that's what I/we usually do ...

Hi Moritz,

somehow, monetdb seems to think that "mserver5" is called "/home/bruder/monetdb-root/bin/monetdbd-dsh" in your case, but that "/home/bruder/monetdb-root/bin/monetdbd-dsh" seems to be "monetdbd" !? This is also reflected/confirmed by your dbfarm properties: " mserver /home/bruder/monetdb-root/bin/monetdbd-dsh "
Well, your configure uses --program-suffix='-dsh', hence, the -dsh suffix for all your commands, but I have no idea why your dbfarm / monetdbd / monetdb "confuse" mserver5-dsh & monetdbd-dsh ?
How did you start your monetdbd? I.e., what was the exact command line?
Best, Stefan

Hi,
so I read several times on the mailing-list, that it is indeed possible to run several MonetDB instances on the same server. I tried this myself with the following configuration:
System: Linux ... 3.13.0-79-generic #123-Ubuntu SMP Fri Feb 19 14:27:58 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux MonetDB version: mercurial revision 324165f1d055 from branch default (also tested with the topmost version) Configure script parameters: --disable-geom --disable-fits --disable-netcdf --disable-lidar --disable-shp --disable-gsl --disable-rintegration --disable-pyintegration --disable-jdbc --prefix=/home/bruder/monetdb-root --disable-assert --disable-testing --enable-optimize --program-suffix='-dsh'
- Another version is running with a different user on the default port
50000 2. With my user, I set up a local db-farm, using port 49999. (A prefix is used on binaries, to prevent any conflicts with the existing version.)
Creating a new database with *monetdbd* works, but once I try to start it with *monetdb*, it gives me the following error message:
starting database 'test'... FAILED start: starting 'test' failed: database 'test' appears to shutitself down after starting, check monetdbd's logfile for possible hints
Another thing I tried was starting mserver5 by hand: mserver5-dsh --dbpath=/home/bruder/monetdb-dbfarm/test --set merovingian_uri=mapi:monetdb://dbiron2:49999/test --set mapi_open=false --set mapi_port=0 --set mapi_usock=/home/bruder/monetdb-dbfarm/test/.mapi.sock --set monet_vault_key=/home/bruder/monetdb-dbfarm/test/.vaultkey --set gdk_nr_threads=16 --set max_clients=64 --set sql_optimizer=default_pipe --set monet_daemon=yes This time it won't accept my password (I assume the default password is *monetdb*): mclient-dsh -p49999 -dtest -umonetdb InvalidCredentialsException:checkCredentials:invalid credentials for user 'monetdb'
I added the log file and the properties of the db-farm.

Moritz
