Dear friends,

If you are running Enterprise Edition RAC, you can limit CPU with the Resource Manager. It is quite possible that the node evictions are because of CPU usage, so you must do this. Setting the css priority might also help, raise it to the maximum if that has not been done already.
Alternatively, if the CPU usage is high because sessions are not being balanced across both nodes, you will need to investigate the connect time load balancing that you have set up.

Note that this is John not me that suggest you that.
I think you can but I advise you to ask your sysadmin.
