Additional Information
When you request statistics for files that are referenced with recoup chain-chasing indicator (RCI) IDs, the display will be different depending on whether there was a full recoup or a selective recoup done for those IDs.
Examples
The following example displays the statistics for a B+Tree data file (file ID FDED) and an associated B+Tree index file (file ID BBBB). The B+Tree file has 8000 data blocks and 421 nodes. File version 00 of FDED shows the statistics for the prime block. It shows one block (the prime block). File version 01 of FDED shows that 7999 overflow data blocks have been chain chased. File version 00 of BBBB shows the statistics for the node blocks.
