The oncheck -pr command

The database server stores chunk information in the reserved pages PAGE_1PCHUNK and PAGE_2PCHUNK.

To list the contents of the reserve pages, run oncheck -pr. The following example shows sample output for oncheck -pr. This output is essentially the same as the onstat -d output; however, if the chunk information has changed since the last checkpoint, these changes are not in the oncheck -pr output.
