Hi,

What is meant by GCS Shadow process? During RAC instance recovery,the content of alert log is,

Quote:

LMS 0: 0 GCS shadows cancelled, 0 closed
LMS 1: 0 GCS shadows cancelled, 0 closed
Set master node info
Submitted all remote-enqueue requests
Dwn-cvts replayed, VALBLKs dubious
All grantable enqueues granted

LMS 0: 1801 GCS shadows traversed, 329 replayed
LMS 1: 1778 GCS shadows traversed, 302 replayed
Submitted all GCS remote-cache requests
Fix write in gcs resources
Reconfiguration complete

Can anyone please explain,what these two events are,

1. LMS 0: 0 GCS shadows cancelled, 0 closed
2. LMS 0: 1801 GCS shadows traversed, 329 replayed

Thanks..
