Hi,

It is the server process which write redo records into the redo log buffer.

For the server process to write this redo records, it has to first acquire a redo allocation latch and there after, redo copy latch.

Redo allocation latch controls the allocation of space for redo entries in the redo log buffer. There is one redo allocation latch per instance.

Once the space is allocated in redo log buffer cache, the server process will acquire the redo copy latch, for copying the redo’s to redo log buffer.

Can some one correct my understanding on Redo allocation and Redo copy latch, if it wrong.

Thanks
Naveen.
