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.
