HTH, Peter Schauss -----Original Message----- From: oracle-l-bounce@freelists.org [mailto:oracle-l-bounce@freelists.org] On Behalf Of Marquez, Chris Sent: Thursday, May 19, 2005 11:39 AM To: oracle-l@freelists.org Subject: ORA-07445, "SIGSEGV", & "address"??? All, I am about to open a TAR...painfully. Had a database (server?) crash a 2AM. Further sadness, the node/instance that crashed hung the other RAC node/instance...could not pull of the RAC reconfiguration...a whole other issue. One crash leads to another crash/hang :o|) I would like to get comments on the true meaning of "SIGBUS", "SIGSEGV", "...physical address", "...Address not mapped". I have always believed these to be Oracle/OS memory related issues?
