DBMINRESBYTES, Minimum RESERVED BYTES value required for certification/upgrade is xxx - Currently is yyy
DBCERTIFY/MUPIP Error: DBCERTIFY and MUPIP UPGRADE report this error when the reserved bytes field of the database file header (as shown by DSE DUMP -FILEHEADER) is not at a sufficient value for the GT.M V5 upgrade.
Action: Increase the reserved bytes value with either MUPIP or DSE so that the value is at least 8 bytes for UNIX and 9 bytes for OpenVMS. Note that the reserved bytes value is reduced by the above amounts by MUPIP UPGRADE.
