I'm working on an Oracle cluster which is running on Sun Solaris.
Everything was working till yesterday which we restarted it. Now I'm trying to take a backup and following error appears:
EXP-00008: ORACLE error 607 encountered
ORA-00607: Internal error occurred while making a change to a data block
