2486154 - How to increase performance on altering a table column ?


  • There is a business requirement to change the data type of a column from numeric(7,0) to numeric(9,0).
  • Some of the tables are huge and are taking more than 48 hours.
  • Tried doing straight alters and by dropping indices first and recreating them after the alters.
  • But, both these methods are taking about the same time.

Can you please advise on the strategies and server config parameters we should use?
