The database server that is mentioned in the current command resides on an NFS- or RFS-mounted file system. However, no entry exists with the NFS or RFS host for the dbservername that is listed in the sqlhosts file. Ask your Informix database administrator to add the entry to the sqlhosts file. If you are using IBM Informix SE, be sure that an sqlexecd daemon is running on the NFS or RFS host.
