Hi,
We have ODA box(2 node with 11gR2) as a Primary and ODA box(2 node with 11gR2) as a standby. Till yesterday evening both Primary and Standby were in sync. Afterwards we were moving indexes to another tablespace and index rebuilding in Primary. After this log transport not happening and below error we were getting in Primary alert log. Database protection mode is 'maximum availability'.
