What does really mean by Grock?

Hello gurus,

I have a question, what does Grock in Oracle RAC CSS?
I always find some info of Grock associate of ocssd.log, as below:
"
2011-04-29 04:00:19.056: [CSSD] [1076291904] clssgmQueueShare: overall grock DBPROD 0 1 queue of customer (0x2aaab00cbd60) Member, global target type (0x2aaab001a980)
Grock DBPROD, refcount 12
2011-04-29 04:00:19.063: [CSSD] [1076291904] clssgmQueueShare: type (0x2aaab0133fd0) target local grock DG_LOCAL_DATA 0 1 member queue of customer (0x2aaab0150760),.
local Grock DG_LOCAL_DATA, refcount 11 "

I searched this word, but not exactly the result.

Hi mac;

Grock is essentially an internal structure to keep css Group management information.
