I'm experimenting with a basic cluster configuration inside Virtual
Box (running Ubuntu 10.04 LTS) using
MySQL distrib mysql-5.5.22 ndb-7.2.6, for linux2.6 (x86_64). (I've
downloaded the latest generic Linux
binary from the main website.)
I've successfully set up a working cluster inside a single VM
(obviously just for testing), which contains
two ndb_mgmd, two ndbd and two mysqld nodes. (In production I plan to
run these on two or more
I've posted my cluster configuration and the outline of how I start
my processes to pastebin.
Everything works fine, but I've noticed that there are four ndbd
processes running on the machine.
I've posted some info on these four processes to pastebin too.
I've noticed that each two processes are in a parent-child
relationship, and I figure that this *could*
be normal, but I'm not sure. Anyone has an explanation why is this
happening? (I didn't find info
on this particular matter in the MySQL 5.5 Reference Manual - not yet at least.)
Thanks in advance!
