Subj:   Building Secondary Indexes
 
From:   Doorey, Andrew ST

We had a failure where a database ran out of space whilst creating a secondary index on a table. This database was 40Gb and contained one large table which was 32Gb without the index and 36Gb once it had been built. I checked the table for skewing, but this was not the reason it ran out of space.

Can anyone explain why this failed as there was 4Gb free space? From the sizes of the table and database involved I guess that it needs twice the space of the index whilst it is being built, but this is purely a guess.


Thanks,

Andy Doorey.
