Hello,
I am about to (fingers and mouse at the ready) install DB2 on a Linux
machine using the db2setup command. All is well. But ....
During the install it asks if I want to create an instance, which I
believe I do. My hesitation is that this computer will be the co-
ordinator node for a multi-node (two computers) system in the very near
future. I need to have a single node for now, using many disks and
partition across the disks for performance. I then need the metrics of
how long particular queries take. From there, I will add a second node
and partition across the nodes and take the metrics of how long those
same queries take. This is all for planning purposes on how many
machines, and what kind of horse-power is needed.
My question is : Do I create an instance now? Can I then add a node
without re-creating the instance I already have?
If I create an instance on this machine, should I use the PARTITIONED
INSTANCE option of the setup? I will be partitioning across the three or
so disks that I have (if I were to just stripe the TS across the disks, I
cannot control where the partitions of the primary key are stored - I
THINK) so I am inclined to think that I use the PARTITIONED INSTANCE
option.
I'm kinda new to PDF, so please excuse any silliness to this post.
Thanks,
Mairhtin
