Re: Wait LCP to ensure durability
The IO threads are using count=1, this is a bit of a misnomer.
There is a lot of IO threads, one for each open file at least
and in addition by default 2 threads for tablespace files.
In the configuration it is mandatory to set count, so it must
be set to 1, for IO threads we actually ignore this number.
These threads are most likely the threads with tid's a bit
higher (in the 8000 and 9000 ranges).
You can get even better understanding which are the IO threads
by ensuring that top prints the last CPU the thread executed on.
The IO threads should all have executed last on CPU 11.
