Subj: | | Re: Updates using MLOAD SESSIONS |
|
From: | | Frank Martinez |
Multiple sessions are created by Multiload anyway! The sessions command only specifies how many, as opposed to the default which is
something like "The number of amps + 2" (ok, it's 7:00am, I don't remember right now). Whoa, if you've sorted the input file by the Primary
Index, you COULD cause yourself a hot amp! Or rather worse, a rolling hot amp! Setting the sessions to one would ensure that you have
reduced a massively parallel processing database to a non-parallel processing one! Why the heck do you want to do THAT? And why in
anyone's right mind would you worry about the ORDER of updates? Uh, this is set processing, remember? The definition of relational, even
the way SQL "thinks" about doing things is by sets. Let's hear what you want to accomplish, ok?
