# DBSPACETEMP:
# OnLine equivalent of DBTEMP for SE. This is the list of dbspaces

# If specified it must be a colon separated list of dbspaces that exist
# when the OnLine system is brought online. If not specified, or if
# all dbspaces specified are invalid, various ad hoc queries will create
# temporary files in /tmp instead.
DBSPACETEMP # Default temp dbspaces
# DUMP*:
# The following parameters control the type of diagnostics information which
# is preserved when an unanticipated error condition (assertion failure) occurs
# during OnLine operations.
# For DUMPSHMEM, DUMPGCORE and DUMPCORE 1 means Yes, 0 means No.
DUMPDIR /tmp # Preserve diagnostics in this directory
