Hi ,
I have few doubts about coalesce tablespace in 9i.
1) Will it free within a segment in 9i?
2) Does it has effect on LMT ?
3) My all tablespaces are LMT therefore what & how much effect
will coalesce have ?
Please let me know any major issues with it.
Rgds,
Somu |

LMT tablespace mostly no fragmentation.
But you can look for the object details in dba_segments -->empty blocks and once you run coalesce tablespace identify the difference in empty_blocks column for dba_segments for all objects create on that tablespace.
Thanks,
Satya
