Hi,
I got a message in the orclALERT.LOG that means:
Thread 1 advanced to long sequence <NUMBER>
Current log# 3 seq# <NUMBER> mem# 0: D:\<PATH>\REDO01.LOG
This message appears over the whole day (about every minute) and increases the file size of the alert log so that it takes a large amount of disk space.
Can anyone please tell me what I have to do. Or if I can ignore this massage. (Sorry, I'm new

)
Thank You!
