# Database drivers
#
# Two pools are given here. Sybase uses the Sybase client libraries,
# obtained from Sybase. Postgres is freely available at
# www.postgresql.org. Sybase uses an external proxy daemon while
# Postgres uses an internal driver. The Sybase driver requires some
# configuration in ns/db/driver/sybase_driver to tell th "nsext.so"
# driver where to find the nssybpd executable and some other things.
# The Postgres driver doesn't need any of that because it's internal
# and does not use nsext.so.

# Accessing DB pools
#
# In the case of virtual servers you can give different virtual
# servers access to different databases, or you can let them access
# them all. AOLserver 3.x does not use virtual servers so the only
# useful value is "*", but if you use one config file for multiple nsd
# processes, or you are using a version of AOLserver that supports
# virtual servers, then you should list the pools you want to access.
#
ns_section "ns/server/${servername}/db"
ns_param pools * ;# Wildcard gives access to all

# Loading a Tcl module
