  • ONLINE VERIFICATION OF A STANDBY DATABASE IN LOG SHIPPING PHYSICAL REPLICATION ENVIRONMENTS
    Publication number: 20130246358
    Abstract: Techniques are disclosed for performing an operation for determining whether a standby database is synchronized with a primary database in a log shipping physical database replication environment. In one embodiment, the operation may include receiving a transaction log at the standby database from the primary database. The transaction log may specify a first one or more checksum values for a first set of pages on the primary database. The operation may also include calculating a second one or more checksum values for a second set of pages on the standby database. The operation may also include determining whether the standby database is synchronized with the primary database by comparing the first one or more checksum values with the second one or more checksum values.
