There is no manpage information for db_open, which is the current version of the database toolkit that comes in db.h. There is documentation for dbopen, but that does not seem to exist in RedHat 6.0.
This issue has been forwarded to a developer for further action.
My suggestion is to create fast workaround. The original Sleepy Cat documentation shall be included to the system documentation for the version that comes originally with the system. problem is that Sleepy Cat provides documentation for the latest release (currently 2.7.5) that sligtly differs from the one in RH60, e.g. see DB_RUNRECOVERY error code. RH team can release this workaround as documentation errata.

it's called "dbopen", not "db_open" and is present in Red Hat Linux 6.2
