The dbcc commands that you use to check page allocation are
dbcc checkalloc, dbcc indexalloc, dbcc
tablealloc, and dbcc textalloc.
dbcc checkalloc
If you do not provide a database name, dbcc checkalloc checks the current database.
dbcc indexalloc
dbcc indexalloc is an index-level version of dbcc checkalloc, providing the same integrity checks on an individual index, including checking for index partitions.
dbcc tablealloc
dbcc tablealloc requires that you specify the table name, the data partition ID, or the table’s object ID from the ID column in sysobjects.
dbcc textalloc
dbcc textalloc checks the allocation integrity of an object’s text and image data, and reports and fixes any problems it finds.
