Shiva,
I am using a service to connect to the instance thru sqlplusw. This service is not-TAF Enabled. So no pre-connect nothing. When I make a connection to any of the instances, I see parallel processes/slaves on the other two nodes/instances to which I have not connected. On the other node the process looks like "ora_pz99_* ". I have tried to research this. I have not got much info. But I don't have a clue why this is happening. The parallel parameters
Those are the parallel query slave processes used to get the information from gv$ views. They are exclusively used to access the gv$views and you do not have any control over that. -- Best Regards, K Gopalakrishnan Co-Author: Oracle Wait Interface, Oracle Press 2004 http://www.amazon.com/exec/obidos/tg/detail/-/007222729X/ Author: Oracle Database 10g RAC Handbook, Oracle Press 2006 http://www.amazon.com/gp/product/007146509X/ -- //www.freelists.org/webpage/oracle-l
