    Unanswered: ORA-07445: core dump in kkogbro()

    Dear all,

    when issuing a view query through a web browser (oracle forms) the remote client receives ora-3113, at the same time alert.log shows:

    ORA-07445: exception encountered: core dump kkogbro()+192 SIGSEGV Address not mapped to object 0x000000000.

    These are the details of the environment:
    Oracle Database 10g Release - 64bit Production
    With the Real Application Clusters option
    System name: Linux
    Release: 2.6.9-
    Version: #1 SMP Wed May 2 15:06:32 PDT 2007
    Machine: x86_64

    Is this an oracle bug or can it be solved?

    Thank you very much for any help!
    Kind regards!

    You can lead some folks to knowledge, but you can not make them think.
    The average person thinks he's above average!
    For most folks, they don't know, what they don't know.

    Thanks for the reply. This is most probably a bug according to OS.

    Saw somewhere though that
    SQL> alter system flush shared_pool;
    SQL> alter system flush buffer_cache

    can delay the this occurrence...does anybody have an opinion on this? Is it a good idea to do this on a production database, and can it negatively influence on something else except for the temporary performance downgrade since the objects need to be retrieved back to the SGA

    Kind regards.
