GoldenGate on RAC


A number of architectural options are available to Oracle RAC, particularly surrounding storage.

Let's start by looking at the importance of shared storage.

RAC relies on shared storage in order to support a single database having multiple instances, residing on individual nodes. Therefore, as a minimum the GoldenGate checkpoint and trail files must be on the shared storage so all Oracle instances can "see" them. Should a node fail, a surviving node can "take the reins" and continue the data replication without interruption.

Since Oracle 11g Release 2, in addition to ASM, the shared storage can be an ACFS or a DBFS.
