Okay ... so this is 9204 db, and I am trying to correctly interpret the MAX.WAIT column value for 'global cache cr request' ... I assume that max wait means in all waits this was the max value for given wait event. right? If so, Did I really have wait of 3288.24 (seconds, centi seconds, milliseconds???)

If so, I can't see that in the trace file, I checked all the 'ela=' values for wait event g_c_cr_r .... where the heck this value 3288.24 came from? And how do I find it? Truse me, the trace file is > 5G.
