In your database， the Log Writer （LGWR） process is unable to write to a member of a current redo log group due to read/write failure. Which two effects would you see in your database？（）
A:The database instance aborts.
B:The database operation temporarily halts till the member becomes available.
C:Writing proceeds as normal. LGWR writes to the available members of a group and ignores the unavailable members.
D:The member would be marked as STALE and an error message would be written to the alert log file and LGWR trace file.
E:The status of the group changes to INACTIVE and an error message would be written to the alert log file and LGWR trace file.
