Creation of gaps in standby

edited Jul 30, 2013 10:09AM in High Availability Data Guard, Sharding and Global Data Services (MOSC) 2 commentsAnswered
 Hello Team,I have few confusions regarding creation of gaps of standby logs:

- If the database (11.2.0.3) is in force logging mode, will the dynamic PL/SQL statements having NOLOGGING options (INSERT /*+ APPEND */, CTAS NOLOGGING) override the force logging mode and start creating gaps in standby?

- I have two node RAC (Primary) and one node active DR with Physical Data Guard, we always find gaps in thread 2 in standby. Does this thread 2 signifies, logs from node 2 of primary is having trouble shipping logs and thus resulting gaps? Do i need to enable both nodes in standby ?

Thanks !

Howdy, Stranger!
