    Hi guys,
    I found the following error in the alert file, will this cause any problems for database? It did show regular archive log after those errors.

    is this ur latest & last alert log errror message in that file

    Check the space in the disk where archived log files are there.

    Also query the V$log, V$logfile to see the status of the redolog files.

    If everythinhg what vendechukp said is correct, check if the Directory has right permissions. Sometime (it has been seen on NT) Windows explorer changed the directory permission.

    I check the views, the redo logs looks fine. The wired thing is normally the database has lots of activity during the weekend, and about 8 archived log generated for Sunday, I query the v$archived_log, I only saw one archived log on Sunday. will this mean the database has slow performance during the day, and less transactions? will the error messge mean the archive process is behind of the log writer, so the resource wait on the log, it could cause slow database application? even though, it did catched up on Monday, I check the view and alert, it looks fine on Monday.

    thanks,

    You have three archive background processes running. While one redo log is being archived by one process the other archive process also trying to archive it and resulting in error.

    I think you can ignore this error.

    I agree with you.
    As tom said, this is the normal behavior.Oracle does not know other process is archiving the redo, so multiple arch processes will try to archive the same one.
    you can look at the alert file, all groups are finally successfully archived.
