Check Reserved Pages with -cr and -cR

The -cr option checks each of the root dbspace reserved pages (see Reserved Pages) as follows:

• It validates the contents of the ONCONFIG file with the PAGE_CONFIG reserved page.
• It ensures that all chunks can be opened, that chunks do not overlap, and that chunk sizes are correct.

The following example checks each of the root dbspace reserved pages:

oncheck -cr

The -cR option performs the same operations as the -cr option, but it also checks all logical-log and physical-log pages for consistency. The -cr option is considerably faster because it does not check the log-file pages.

If you have changed the value of a configuration parameter (either through ISA, onparams, onmonitor, onspaces, or by editing the configuration file), but you have not yet reinitialized shared memory, oncheck -cr and oncheck -cR detect the inconsistency and return an error message.

If oncheck -cr does not display any error messages after you execute it, you can assume that all three items in the preceding list were checked successfully.
