In my Redhat server , I have a database is running on it , I have the below message is often appear in the database , I am not sure what is it , but I am wonder why it pop that we have root user login from console ( message 1 ) , is it mean someone use root user to login the database from console ? I sure we do not do it , we seldom login from console , but the message pop frenquently , can advise what is it mean ? the message 2 is from another database ( another server ) , it also pop frenquently , it seems mean root run batch in the database , I think it is normal as we run some batch job from root user , can advise how to fix the error of message 1 ? thx

message 1
=======
Login by root on /dev/console


message 2
=======
Login by root on batch

I guess the first question would be, which database engine? That could make a difference.

Your English makes it sort of hard to understand exactly what you're asking, but I'm going to interpret it this way: if the message is in the database engine's logs but not in the system logs, the problem may not be system root at all, but rather the database engine's "root" user. Yes, this is a guess, but the best I can do at the moment.
