    ORA-07445: exception encountered: core dump

    Hi,

    I am not much experience in oracle. I have one issue regarding oracle core dump.

    From alert log file I got following message.

    Errors in file /opt/oracle/u01/admin/CEMSDB/udump/cemsdb_ora_24373.trc:
    ORA-07445: exception encountered: core dump [0000000100FFA0E8] [SIGSEGV] [Address not mapped to object] [0x00000015A] [
    ] []

    I have checked to access cemsdb_ora_24373.trc file but it doesn't exist.

    I have stack trace the core dump file for oracle from that I got following message.
    core 'crash.oracle.24373' of 24373: oracleCEMSDB (LOCAL=NO)

    I really don't understand any of the above conents. I think there is problem with oracle, I have also checked listener.log file but I don't get anything from that.

    Why core dump file is generated for oracle. Please guide me what was the root cause of this problem?

    Log an SR. This is internal Oracle error
