Hi All,

When looking at v$latch it gave me the following stats for 'redo copy'

GETS: 35
MISSES: 21
IMMEDIATE_GETS: 326975
IMMEDIATE_MISSES: 65 according to my understanding 'redo copy' is required when the process writes to the redo buffer. am i right?

if i'm right, why is it that this latch is requested with a no-wait option(evident from high IMMEDIATE_GETS as compared to GETS).

regards
Naveen
