# Configuration file for MonetDB Version 5 server

# The configuration file is an integral part of a database store
# and aimed to initialize the server and service components.
# This startup file is read by the GDK kernel to set system wide parameters. 

# It may be inspected by application/scripts for specific settings,
# but such client side configurations are better packed in their
# own structure.

# It can also reside in the local directory
# where mserver is called, or the home directory of the MonetDB user.

# Absolute path where MonetDB is installed
prefix=/ufs/mk/monet5/Linux

# GDK Section
#============
# All databases are stored as a directory under the directory
# given below.  Use this value to change the overall location
# of your data.

# MonetDB can only handle one database at a time.  You can specify
# the name of the database to use below.  Note that you can use
# multiple databases, but that you have to edit the database name
# and restart MonetDB.

# The options below deal with various aspects of memory usage behaviour.
# If you don't know what these values mean, you should leave them alone.

# gdk_mem_bigsize & gdk_vm_minsize will be set/limited to
# 1/2 of the physically available amount of main-memory
# during start-up in src/tools/mserver.mx
# memory chunks of size >= gdk_mem_bigsize (in bytes) will be mmaped anonymously

# valgrind issues:
# for 32 bit systems it tries claim 3G of (virtual) memory
# set the alloca map to "no" to run mserver with valgrind;
# also, you need to tell valgrind to use 8-byte alignment, hence:
# "valgrind --alignment=8 mserver --set gdk_alloc_map=no ..."
