Hi,
control file sequential read
Reading from the controlfile. This happens in many cases. For example, while:

making a backup of the controlfiles

sharing information (between instances) from the controlfile

reading other blocks from the controlfiles

reading the header block

Wait Time: The wait time is the elapsed time of the read.

Parameters:

file#
The controlfile from which the session is reading.

block#
Block number in the controlfile from where the session starts to read. The block size is the physical block size of the port (usually 512 bytes, some UNIX ports have 1 or 2 Kilobytes).

blocks
The number of blocks that the session is trying to read.
