Folks,
I know that when creating indexes a couple of settings such as
SORT_AREA_SIZE can have a big impact on duration. What settings apply
during online rebuilds? Are the rules the same? What tips do you have?
Basically we have some very large indexes in an OLTP system (several
indexes are across ~250m rows, several GB in physical storage) which have
fairly low density due to deletes and updates. In looks like the time has
come to rebuild then to gain some performance. Any other suggestions
regarding tricks to avoid this, etc would be greatly appreciated.
Thanks,
Mark.
PS: If you going to suggest things which are version specific we're
dealing with 8.1.7.4 on Solaris.
