OpenEdge Replication and after-imaging : Calculating current database after-image volume : Using the RFUTIL command

Using the RFUTIL command

To determine the after-image volume from the command line, you must run the following command at the start and at the end of your desired time frame:
rfutil db-name -C aimage extent list
The after-image extent size is shown in 1K blocks. Subtract the end value from the start value to determine how many blocks (count) have been written. Use this value to calculate the after-image generation rate per period depending on the network rate desired. It is important to note that emptying the after-image extents negates this method, as it changes the after-image block counts within the extent to zero.
