Home -> Community -> Mailing Lists -> Oracle-L -> RE: Core dump with ora 7445
Can you fill me in on your setup? We are getting very similar behavior (a
core dump on constraint violation was one of several triggering events) on
our Digital 4.0d server running 8.1.5. Are you on similar hardware? If so we
should go off-list and share notes on my currently opened TAR on this
(12833964.600). We get core dumps from any unhandled user exception from
some, but not all, client applications. This seems like either an Oracle bug
or a client setup issue, because the same piece of code can cause an
ORA-7445 & core dump & end of file on communications channel on SQL
Worksheet or TOAD, but not on SQL*Plus, all running on the same client
against the same server/instance. I'm looking into kernel settings right now
(signal 11 is a segmentation fault, after all), and Oracle has issued bug
1282252 on the issue.
I'll be out in Anaheim at IOUG-A if anyone wants to share notes on the joys of ORA-7445's with me. Also won't have access to my regular email the whole time, so please send to cjgait_at_yahoo.com if you want to talk about it this coming week.
