    Regarding Checkpoint & Dirty Buffers

    First of all thanks for all the responses. I am clear that the First point is right and SYBEX has made a mistake either "theoritically" or "English Language Based".




    ..Well.. again, you see you may derive your own way of understanding things to benefit your convinience of notions. But 'ENGLISH' remains the same. A statement of meaning can only be precise..it cannot be "Subjective" left to the imaginations of the reader. A "technical statement" ought to be precise and not poetry. I hope you will agree.

    Your words of "Allows" and "Requires" are your imaginations to suit your notion, it has no bearing on what SYBEX has said as "A checkpoint occurs when the dirty buffers are written to the disk" . To me, I am in no-way supportive to this statement of SYBEX, regardless of how one would want to interpret based on their convinences. In My Honest Opinion, it's a GROSS MISTAKE on SYBEX's part of either "understanding the concepts" or "English Usage". Period.
    Irrespective of what the SYBEX is saying is not to our discomfiture.
    Nevertheless whatever database might be it is all for the sole reason of basic nomenclature and same can be construed for all databases as ORACLE being one of them.

    It is very interesting and misleading when the AUTHOR of this query poser mentioned the misleading factor of Checkpoint behaviour.

    Perhaps there should be misconstrued by readers and the same can be interpreted.

    Anyhow very nice discussion and good understanding

    I have no idea what a "convenience of notions" is, or how my "word of" allow and requires are "imaginations", but if the point you were raising is that technical documentation is often poorly written/inaccurate then you are quite right. That's why I pointed you towards the Oracle manuals -- they are (usually) much more accurate, and often better written, than books by third-parties. The main thing is that we all now understand the relationship between checkpoints and dirty buffers, I think.

    For a real feast of inaccuracies and misleading statements, try "SQL for Dummies" -- it's a real laugh.
