Connect to SYSDBA from inside SQLplus? Default password?

Question

Ok, I could call SQLplus with the SYSDBA user as
sqlplus / as sysdba
but assume I am in a SQLplus session as SYSTEM user and I just want to quick switch to SYSDBA
through a "conn" command and execute some instructions?
How can I do this? How is the default password of SYSDBA (and SYSOPER) ?
the following does not work:
SQL>conn SYSDBA/sysdba
How else can I connect?

PeterPeter,
Well first of all, there is no user called SYSDBA, Its a role not a user. Here is the link which tells what this role contains and another SysOPER also,
http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/dba.htm#sthref137
Now the comamnd that you have given, connect sysdba/sysdba, is wrong fron start to finish as there is no user like this. One may think that the option to quickly switch can be setting the current schema to sys but that also doesn't work for SYS user,
