LMS process
Hi,
Global cache services (LMSn) are processes that, when spawned by Oracle,
copy blocks directly from the holding instance’s buffer cache and send a
read-consistent copy of the block to the foreground process on the requesting
instance.
LMS also performs a rollback on any uncommitted transactions
for any blocks that are being requested for consistent read by the remote
instance.
what is the meaning of the above statments .
For example 3 instance named as x,y,z
X is holding instance and y is requesting instance.
which LMS process is resposible for rollback whether X or Y
