How to turn off index and turn on index? We have big fact table with 64 milion rows per month. To load this huge table I want to turn off index and after laoding i want to turn on index. How to do this through informatica/database?
 
Simply include the Index Drop and Index Create DDL in Pre and Post SQL for the Mapping connections
 
With Index drop and create it needs to create indexes from scrach. Can it be possible to update existing indexes?
 
After large operations on a table it is always smart to execute statistics. This will ensure that the optimizer will have up-to-date info.

Will the indexes be updated with 'Update Statistics' without recreation?
 
This behavior may vary between RDBMS. You should look into the specifics of the target database you are working with.
My 2 cents: without specifying, both column and index statistics will be updated.
