    Unanswered: Oracle datafiles....

    Hi All,
    I have an AIX 5.3 box with Oracle 10g installed. I cannot seem to open the oracle datafiles which are currently opened by the Oracle DBWR process. Is there any way to prevent Oracle processes from opening the datafiles in exclusive mode?

    Thanks,
    rajar

    Not as far as I know.
    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.
    Good judgement comes from experience. Experience comes from bad judgement.

    Oracle datafiles....

    I have written a program which is suppose to get a hexdump of a block. The program uses open64() call and tries to open the file in O_RDONLY mode. It fails with EINVAL. Found that if the oracle process DBWR is running, the file open fails. If the DB instance is brought down, then I can open the file.

    Thanks,

    So open the file when DB instance is down

    Or, make a backup copy of the file and do with it (with the spare one, I mean) what you want.
