This will reduce the number of blocks that may have to be logged to the minimum possible.Restore the size of the active window after you maximize it. To limit the effect of this additional logging, you should ensure you only place one tablepspace at a time in backup mode and bring the tablespace out of backup mode as soon as you have backed it up.

This lets the recovery process understand what archive redo log files might be needed to fully recover this file. The datafile headers which contain the SCN of the last completed checkpoint are not updated while a file is in hot backup mode. Hence, we log the entire block image so that during recovery, this block is totally rewritten from redo and is consistent with itself atleast. We cannot deal with that during recovery. The backup program has now gotten an fractured block - the head and tail are from two points in time. The backup program starts running again (multi-tasking OS here) and reads the last 4k of the block. the OS schedules the DBWR write to occur right now.

Meanwhile - DBWR has asked to rewrite this block. The backup program goes to read an 8k Oracle block. Lets say they are and the OS blocking read factor is 512bytes (the OS reads 512 bytes from disk at a time). This is because you can get into a situation where the process copying the datafile and DBWR are working on the same block simultaneously. In hot backup mode, the entire block is logged the first time. Normally only the changed bytes (a redo vector) is written. The first time a block is changed in a datafile that is in hot backup mode, the entire block is written to the redo log files, not just the changed bytes. Therefore oracle internally manages the consistency as below :ġ. The result is called a fractured block, meaning that the data contained in this block is not consistent. In this case, the copy utility may read the old data in the top half of the block and the new data in the bottom top half of the block. Also, assume that the copy utility reads the entire block while DBWR is in the middle of updating the block. For example, assume that you are backing up block 100 in datafile users.dbf. One danger in making online backups is the possibility of inconsistent data within a block. + Copy all the datafiles using appropriate O/S commands. Performing a full database backup (starting from 10g) + sql>alter tablespace system end backup + Copy the corresponding datafiles using appropriate O/S commands. + sql>alter tablespace system begin backup Make sure that the database is in archivelog mode From 10g onwards the entire database can be put in begin/end backup mode. In 8i, 9i we have to put each tablespace individually in begin/end backup mode to perform the online backup. To perform online/hot backup we have to put the tablespace in begin backup mode followed by copying the datafiles and then putting the tablespace to end backup.
