NNO-00058: cannot load topology data from configuration database



NNO-00058: cannot load topology data from configuration database..

Answer / guest

Cause: An error was encountered while trying to load the
server's topology data from the configuration database. If
more information is available, it will appear under this
error. This error will cause the server to shut down.

Action: Make sure that the database is running, that its
name and password as specified in the Oracle Network Manager
are accurate, and that there is SQL*Net connectivity between
the Oracle Names server and the database. To force the
server to start up anyway, using its checkpoint data, start
the server with the names.no_region_database parameter set
to TRUE. If no checkpoint data is available, the server will
shut down.
