How to rebuild indexes in InnoDB

[Anil Doppalapudi]

Hi,

users are complaining that response time is slow. right now what I am doing
is dropping indexes on table and recreating them. After that Database is
working fine for some days and again it is giving problem. dropping and
recreating indexes taking lot of time. any alternative


Thanks in advance.
