Yanni: For years we have been asking for documentation on how to read the Oracle core, sysstate and errorstack dumps. If I remember and Cary please correct me, a paper was published for Oracle 6 & 7 on how to read some of the data. It is very crude and truly internals-type documentation. I'm not aware of anything in the public market that helps you read the dumps, however, you can, with time, look at one and figure out what's going on. Kala? Thank You Stephen P.
