SpectroRX
SpectroRx uses a problem-solving technique called case-based reasoning to organize
the knowledge about network problems. A case consists of the alarm resolution
information that you enter and additional alarm information provided by SPECTRUM.
As you enter information about new alarms, SpectroRx adds the case to its case
library. When you request information about solutions for a current alarm, SpectroRx
finds the cases that are similar to that alarm and sorts them according to their degree
of similarity to the alarm situation. The most similar case is displayed first, the least
similar last. You review these past cases and adapt the solutions to the current
problem.
SpectroRX Conversion Instructors
The location of SpectroRx has changed from ${SPECROOT}/CBR to
${SPECROOT}/SG-Tools/CBR. With this change, the location of the
database files has also changed. These files (cbr.db, cbr.map, prob_list,
and sol_list) now default to ${SPECROOT}/SG-Tools/CBR/SpecRx. To
change this default, please refer to the section in your manual that
discusses “Customizing the Environment.”
In addition, the structure of the database has changed, both to allow
more freedom in documenting problems (in the Probable Cause files) and
for greater efficiency in accessing the database.
In order to use your existing database(s) with the new SpectroRx, some
changes to the database files will be needed. The first step in this process
is to move the files from their current location (the previous default was
${SPECROOT}/CBR) to the new location (as mentioned above). The
following files need to be moved (this list is comprehensive if you are
missing any file other than the first four, there is no need for concern):
cbr.db cbr.map prob_list sol_list cbr_back.db cbr_back.map
prob_list.bak sol_list.bak
Once these files have been copied to the new location, each must be
modified (make a backup copy first). The changes are as follows (please
