hi all
I tried to exceute the
1.Alter index ORDERLINEITEMJOURNAL_IX1 rebuild;
2.Alter index ORDERLINEITEMJOURNAL_PK rebuild;
on my database on the database server which is at remote location ,so i am accessing it through putty.During the second alter indexd command my server got hanged so i closed the the session(putty) and when again i tried to start the oracle, i got the following error

SQL> startup
ORACLE instance started.

ORA-01110: data file 1: '/data1/seek01/system01.dbf'
ORA-01207: file is more recent than controlfile - old controlfile

can anybody please help me to solve this error. is there any recovery option? so that i am able to start the oracle as it was working fine befor running the alter index command. It's very urgent.
