Dear All,

We tested failover functionality with "shutdown abort" or "shutdown immediate" 
and it works fine. But failover did not happen when one of the Node got crashed
with follwoing error.

ORA-00600: internal error code, arguments: [], [], [], [], [], [], [], []
Instance terminated by SMON, pid = 3245

My tnsnames.ora is configured like below.
=========================================================
mydb=
  (DESCRIPTION=
   (FAILOVER=ON)
   (LOAD_BALANCE=ON)
   (ADDRESS=(PROTOCOL=TCP)(HOST=machine1)(PORT=1521))
   (ADDRESS=(PROTOCOL=TCP)(HOST=machine2)(PORT=1521))
   (CONNECT_DATA=(SERVICE_NAME=mydb.mycompany.com)
                 (FAILOVER_MODE=(TYPE=SELECT)(METHOD=BASIC))))
mydb1=
  (DESCRIPTION=
   (FAILOVER=ON)
   (ADDRESS=(PROTOCOL=TCP)(HOST=machine1)(PORT=1521))
   (ADDRESS=(PROTOCOL=TCP)(HOST=machine2)(PORT=1521))
   (CONNECT_DATA=(SERVICE_NAME=mydb.mycompany.com)
                 (FAILOVER_MODE=(TYPE=SELECT)(METHOD=BASIC))))
mydb2=
  (DESCRIPTION=
   (FAILOVER=ON)
    (ADDRESS=(PROTOCOL=TCP)(HOST=machine2)(PORT=1521))
    (ADDRESS=(PROTOCOL=TCP)(HOST=machine1)(PORT=1521))
    (CONNECT_DATA=(SERVICE_NAME=mydb.mycompany.com)
                    (FAILOVER_MODE=(TYPE=SELECT)(METHOD=BASIC))))

======================================================
Could someone shed lights on this?

Thanks
Jay.
