Why are you running what appears to be an unpatched version of Oracle 11gR2? My first recommendation would be to consider patching to address the numerous known issues... -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Laimutis.Nedzinskas@xxxxxx Sent: Monday, October 07, 2013 8:15 AM To: sbecker6925@xxxxxxxxx Cc: oracle-l Subject: Re: Core dump then database crash Scan alert log for ANY errors/warnings before the crash.

It didn't come all the way down. Some processes were still running so we did a shutdown abort (non-prod database) and restarted it. All looks good now. So far research hasn't yielded any answers about why it crashed. One of the errors is something we haven't seen before. Can anyone shed some light on the following error? ORA-07445: exception encountered: core dump [dbgtrReserveSpace()+100] [SIGSEGV] [ADDR:0x10] [PC:0x107A73284] [Address not mapped to object] [] We appreciate any help or pointing us in the right direction. -- Sandy GHX -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
