- Sometimes, the database management system used in the BDA
software is not installed properly, producing errors like:
System Error #3603:ooHandle(ooFDobj)::open():Cannot open
initializing Schema Database session object
Check to see if the TCP/IP
protocol is installed by clicking the right mouse button on the
"Network Neighborhood" icon on the Desktop, selecting properties, and then
looking in the "Protocols" tab. If TCP/IP
does not appear on the protocols list, install it by clicking on the "Add"
Install the database
management system from a DOS shell. Windows typically installs DOS such
that it can be run from the Start button. It can typically be found under the
"Programs" heading and is usually listed as either "MS-DOS Prompt" or
"Command Prompt" (for Win9x and NT respectively). Once DOS has been started, the
directory must be changed to the BDA directory and the "ooinstallfd" program
should be run as follows:
ooinstallfd -standalone -lockserverhost <name of your
The computer name can be found by clicking the right
mouse button on the "Network Neighborhood" icon on the Desktop, selecting
properties, and then looking in the "Identification" tab.
- In SGE, you can move a space, by selecting it and clicking
on the "move" button, but it is not currently
possible to edit a space by dragging walls or wall joints to change the
size and/or shape. If a
space needs to be edited, it has to be deleted and recreated.
- If you use non-alphanumeric characters
in the name of a project, such as "?" ";", etc., the BDA will complain only when you try to save the project, it will
refuse to save it and quit. Do not use non-alphanumeric characters in project names.
- If you try to draw a window on an interior wall, SGE will
properly notify you that you cannot have windows on interior walls. Sometimes,
though, it will not let you continue, giving you the same error
when you try to draw on an exterior wall. Hitting
the ESC key will take you out of the "window draw" mode and you can start again.
- When you change an Object in the Browser by selecting
another option from the BDA libraries, the left window does
not automatically reflect the changes. Selecting
another object and then the object under consideration will display the updated properties.
- If a crash should occur while running BDA, the user may
notice an "Error: unable
to find oo..." type of message when BDA
is subsequently started. Once this error message is acknowledged, the user should cancel from the Open Project dialog and exit BDA. Then
upon starting BDA again, the error will not occur and the program should
- The placement/removal of roofs is automatically done by the
BDA. When a new space is drawn, the BDA will remove the roofs of any overlapped space on
the floor below. However, the whole roof is removed
for each overlapped space, rather than only a fraction of the roof that corresponds to the
Though BDA allows the user to edit the size
of the drawing area, this is not fully functional as yet. The
user will not be able to draw outside the original drawing area.
This is a known bug which needs to be corrected.
The version of
DOE2.1E that is linked to BDA sometimes hangs with large projects.
Save the project frequently and if the simulation hangs, use the task
manager to exit out of BDA. Try restarting
the project and running the simulation again.
BDA is not backward
compatible. Older versions of BDA projects cannot be
imported into newer versions.
