Detailed Description​

This is a RAC wait. A full table scan or fast full index scan is doing scattered reads for a DML operation.

In RAC wait event names:

  • gc denotes the Global Cache service.
  • current - is for DML operations
  • cr - is for select operations

The difference between CR and Current is that CR requires a block with a given SCN, whereas current does not (current mode fetches the block with the current SCN).
