" 00C90110The data manager detected an inconsistent data condition. This may be caused by an inconsistency in either the DB2P' catalog or the DB2 directory. In this case, the OBD for the requested OBID cannot be located in the database descriptor (DBD). The DBD in storage may be inconsistent. Specifically, the OBDDMAP(OBID) array element should contain an offset into the DBD where the OBD should be located. However, in this case the OBD expected was not at the indicated offset.To prevent further damage and possible loss of data, the inconsistency must be corrected before any further SQL access is attempted to this database."
