Answer 1

I found solution just now, this is very simple i was not aware this but this is how it working
Hope this helps
I granted sysdba from node A but not from node B, thinking that if you grant any privilege at instance level that is applicable to db level but that is not the case with sysdba privs
so i need to grant it from both nodes A and B.
here is the output
test case
initially no entry for instance 2
1) select * from gv$pwfile_users;
INST_ID USERNAME SYSDB SYSOP SYSAS
2 SYS TRUE TRUE FALSE
1 SYS TRUE TRUE FALSE
1 RMAN1 TRUE TRUE FALSE
2) grant sysdba to rman1 -- this I did at NODE B or instance 2
3) SQL> select * from gv$pwfile_users;
INST_ID USERNAME SYSDB SYSOP SYSAS
2 SYS TRUE TRUE FALSE
2 RMAN1 TRUE FALSE FALSE
1 SYS TRUE TRUE FALSE
1 RMAN1 TRUE TRUE FALSE
4) I am able to connect remotely
C:\Documents and Settings\kthoka> sqlplus rman1/rman1@ppmqa "as sysdba"
