Re: Does coalescing a tablespace cure all types of fragmentation?

Hi Cherie,
Coalescing a tablespace only combines extents that are next to each other that have no data blocks in them. In other words, if you have 2 100k extents that are empty and next to each other, after coalescing, you now have 1 200k free extent. This is free space defragmenting. Data defragmenting involves reorging the tablespace.

HTH,
