All-

I ahave implemented the reorgs on my database by using the key column for each table.

Basically the table is clustered by the key column.

Now , i am thinking of reorging the indexes of the few of the tables.

When i do reorg indexes , will it alter the cluster order ?
reorging only indexes will have any peformance impact on the database since i already have reorg by key column.

thanks
