Home -> Community -> Mailing Lists -> Oracle-L -> Re: any problem rebuilding indexes used for replication
I think Jonathan is correct when he says that index rebuilds are not often
needed.
Tom Kyte states that they are never needed, which I don't believe to be correct.
I'll try to back this up with data in the future.
So if Tom asks any of you why you don't use automatic space management in your LMT's, you can ask him why he doesn't use 'alter index rebuild'. ;)

renu (and Jared),
The reason I'm very interested in whether there's performance improvement
is
that there's a thread on the newsgroup about index rebuild recently. See
Jonathan Lewis says there's almost no need to rebuild indexes, although
his
"Practical Oracle8i" lists at least one case you may benefit by
rebuilding. (I
don't have the book with me). Asktom.oracle.com has numerous messages
advising
against rebuilding indexes. Let's set theory aside for a moment and do the
experiment. Please post your report of performance change. Thanks.
