Hi,

I got #GDKrealloc(21474836496) fails error when I tried to run TPC-H benchmark with a scale factor 100. The error happened during loading tables. Here are information about my configuration:

The monetdb version used: changeset: 45737:bfd558546498 tag: tip user: Martin Kersten mk@cwi.nl date: Thu Oct 25 21:55:38 2012 +0200 summary: Add missing variable.

The machine used: 64 bit Ubuntu natty With 7.806 GiB available main-memory.

Compiler option used: 64 bit OIDs used

Runtime options used: /home/borgdb/monetdb/install/bin/mserver5 --set gdk_dbfarm=/home/borgdb/monetdb/dbfarm --dbname=tpch100 --set merovingian_uri=mapi:monetdb://sc-borgdb6:50000/tpch100 --set mapi_open=false --set mapi_port=0 --set mapi_usock=/home/borgdb/monetdb/dbfarm/tpch100/.mapi.sock --set monet_vault_key=/home/borgdb/monetdb/dbfarm/tpch100/.vaultkey --set gdk_nr_threads=8 --set max_clients=64 --set sql_optimizer=default_pipe --set monet_daemon=yes

I am new to monetdb, so I am not sure if that is a known issue. If it is a known issue, my question is: on a 64 bit machine with 7.8GiB memory, how big a scale factor(TPC-H benchmark) can be handled by monetdb with 64 bit OID? If there any runtime option that enables monetdb to handle a big scale factor when run TPC-H benchmark?

On my configuration, I succeeded in running TPC-H with scale factor 10, but failed with every scale factor >= 15.

Any comments will be greatly appreciated,

Thanks, Joe
