When transaction logging is enabled, Lotus Domino assigns a database instance identifier (DBIID) tag to each database. When Lotus Domino records a transaction in the log, it includes the DBIID. During recovery, Lotus Domino uses this DBIID to match transactions to databases.
Some database maintenance activities can cause Lotus Domino to assign a new DBIID to a database. After Lotus Domino assigns a new DBIID, all new transactions recorded in the log use this DBIID. However, any old transactions would still have the old DBIID and would no longer correspond to the new DBIID. As a result, Lotus Domino cannot apply these old transactions to the database.
Note: To avoid losing data, you should immediately perform a full database backup whenever a database receives a new DBIID.
When you perform this backup, you capture all the database transactions up until that point and ensure that Lotus Domino needs only the new transactions (with the new DBIID) to restore the database.
