I performed a cluster archive (8 simultaneous data arcs) of a 170 gb table. Each of the 8 pieces came back in under 8 minutes. Data Dict archive and Release Lock times were small.
When I recover the table (sumitting the copy statements in paralle), it takes 35-40 minutes to recover the 8 data pieces (running in parallel).
The Build Table step is taking less than 5 minutes.
The table in question has a short width and several indices.
The box has ~ 72 amps, 8 nodes.
I have the number of session set at 2 sessions per node.
I would like to get the recovery time down to 200% of the archive time.
I am considering bumping up the number of sessions. However, I don't want to "hog" all the sessions on the box.
Any thoughts or recommendations?
