Hello. 1) I put attention that TNS write events into its log in too big frequency: ~ 10 time in second. I see that it is for every connection, but I assume that this no too good to performance. Is there some way to tell to TNS not to write event for every connection but only for errors? 2) May I to remove alert.log of DB? Or DB will make me problems with this? 3) How can I tell to my client connect directly to my instance rather than during TNS? I have Oracle RAC 11g running on Red Hat 4 64 bit. Thank you for ahead.
