Mark , thank you for reply, the main reason I was asking is:
 I seen several times when I removed  user indexes using admin  console and  after 2-3 days they re-appeared back  ? This is something strange, I am running backups and exports on daily bases on on this database but can explain how the indexes are getting re-create  back ??
Thank you

Hi List,
I would like to know if after removing user indexes using the admin console there is need to run the
db2index.pl script  while the ldap is shutdown  or should be fine to run with DS online?
Thank you
