This means that for the rebuild to start it will need some short term access which can be blocked if another operation is already running (an update for instance). This prevents updates to the underlying table but allows read operations, such as SELECT statements. An offline index operation that creates a nonclustered index acquires a Shared (S) lock on the table. This prevents all user access to the underlying table for the duration of the operation. An offline index operation that creates, rebuilds, or drops a clustered, spatial, or XML index, or rebuilds or drops a nonclustered index, acquires a Schema modification (Sch-M) lock on the table. Table locks are applied for the duration of the index operation. ONLINE cannot be set to ON when an index is being created on a local temporary table. At the end of the operation, an S lock is very briefly held on the source if a nonclustered index is being created, or an SCH-M (Schema Modification) lock is acquired when a clustered index is created or dropped online, or when a clustered or nonclustered index is being rebuilt. At the start of the operation, a Shared (S) lock is very briefly held on the source object. This allows queries or updates to the underlying table and indexes to continue. During the main phase of the index operation, only an Intent Share (IS) lock is held on the source table.

Online index operations are available only in SQL Server Enterprise, Developer, and Evaluation editions. The default is OFF.įor an XML index or spatial index, only ONLINE = OFF is supported, and if ONLINE is set to ON an error is raised. Specifies whether underlying tables and associated indexes are available for queries and data modification during the index operation. also confirm updatestats for table index which is not rebuild the index. confirms as blow parameters mention which is configured all production servers. I have checked at 9 AM there is no table locking and blocking that particular table which was made it rebuild the index.Īs per your script rebuild index is online mode even though table is accessing through application even if locking that table. I have configured index rebuild on weekly basis at 3 AM.in production server, It will create CSVs with the result of the queries in the OutputFolder.
