Hi Andrei Thanks for 'living' at the edge. The octopus module is not (yet) meant for production work, but rather an active area of research & development. As such, I am afraid you can not apply it for now. regards, Martin On 6/7/11 2:51 AM, Andrei Cojocaru wrote:
Hi all,
I am trying to setup (and play around with) a MonetDB-Apr11 cluster since the dataset I am expecting to have is beyond what can fit in the memory one node (starting with at least a few hundred gigabytes). I have been following the instructions athttp://www.monetdb.org/Documentation/Cookbooks/Recipes/Cluster and have a few nodes setup. I ran all the commands given there on all the nodes except for the creation of the master database which I ran on only the master. Also, I set the pipe to octopus_pipe on the master database. In mclient, I ran the following commands (from the sample squid test for octopus in the MonetDB source code):
create table squidA( Bid int, Cval int); create table squidD( Eid int, Fval int);
-- let's fill the tables create procedure fill(lim int) begin declare i int; set i = 0; while i< lim do insert into squidA values(i,rand()); insert into squidD values(i,rand()); set i = i+1; end while; end;
declare size int; set size=100; call fill(size);
It all runs with no errors. However, when I run: select Bid from squidA, I get a screenful of errors. They are all a variation of:
TypeException:octopus.tentacle_3_11[6]:'octopus.bind' undefined in: _18:bat[:oid,:int] := octopus.bind(_2:str, _8:str, _9:str, _13:str, _19:int, _16:int, _17:int, version:int)
Would you be able to offer some guidance on how to get this running? I was considering setting up application level partitioning and run multiple MonetDB instances directly, but if octopus does a lot of that work I would prefer to save myself the development and debugging time.
Thanks for any help you could provide.
