I am facing the issue with SSH user equivalence, i followed the same above steps but while running cluster verification script getting error that user equivalence failed.

Have removed the files under .ssh directory and i again tried the same above steps but still facing the same issue.

$ ssh rsvmsb295 date
The authenticity of host ‘tsbmnv256 (10.156.77.57)’ can’t be established.
RSA key fingerprint is f9:40:94:52:d0:ca:b4:94:7a:ba:48:83:ed:15:34:e4.
Are you sure you want to continue connecting (yes/no)? yes

$ ssh rsvmsb295 date

JUst check the issue and help me and does this ssh equivalence set up modify any root level files?

Do you have a mail server I can try out? –It didn’t work after alter session set smtp_out_server=’www.yahoo.com:25′; (see code below for error: ‘ORA-24247:network access denied by access control list (ACL)’
). Thanks so much. –cwan
