ONS process and high paging
Dear all,
I would like to share with you a problem that we've been facing in the past few days, and hope to get some suggestions or solutions from your side:
First of all we are running an Oracle RAC 10g (10.2.0.3) with two database nodes on two dedicated IBM Power servers with AIX 5.3 as OS.
We have executed a memory upgrade during last week by Replacing on both servers our old 8GB RAM with new 16GB RAM, and after that we increased SGA_target to 8GB and SGA_max_size to 9GB on both instances. Unfortunately the next day one of the instances crashed, after investigation we have noted that there was very high paging activity on the server, so we immediately increased the swap space from 16GB to 48GB and restarted the server.
