Dears,

My production DB is hanging. I am unable to login to the system. It seems that too much logs have been generated and check point not completed.

Thread 1 cannot allocate new log, sequence 229916

Checkpoint not complete

  Current log# 1 seq# 229915 mem# 0: +FRA_DG/hemo/onlinelog/group_1.351.935315765

  Current log# 1 seq# 229915 mem# 1: +REDO_DG/hemo/onlinelog/group_1.341.935315765

Thread 1 advanced to log sequence 229916 (LGWR switch)

  Current log# 2 seq# 229916 mem# 0: +FRA_DG/hemo/onlinelog/group_2.352.935315765

  Current log# 2 seq# 229916 mem# 1: +REDO_DG/hemo/onlinelog/group_2.342.935315765

I need your urgent help please.
