Best is:

c:\set oracle_sid=NJ01
c:\svrmgrl
svmgrl>connect internal
svmgrl>shutdown immediate / shutdown abort
svmgrl>exit

c:\set oracle_sid=NJ02
c:\svrmgrl
svmgrl>connect internal
svmgrl>shutdown immediate / shutdown abort
svmgrl>exit

Once you do this then:

c:\set oracle_sid=NJ01
c:\svrmgrl
svmgrl>connect internal
svmgrl>startup mount
svmgrl>alter database open;
svrmgr>exit

c:\set oracle_sid=NJ02
c:\svrmgrl
svmgrl>connect internal
svmgrl>startup mount
svmgrl>alter database open;
svmgrl>exit
