Domino & DB2 crash: RM unavailable.: An error occurred accessing the db2 datasource

After the emergency power outages turn off two servers: Lotus Domino R8.5.1 and DB2 9.1.5 (storing data in a format DB2). Both servers run on a platform of MS Windows Server 2003 R2. After starting the Lotus Domino Server after some time the server crashes and the console log records the error: “RM unavailable.: An error occurred accessing the db2 datasource.”

Has anyone solved this problem and can help?
