Home -> Community -> Mailing Lists -> Oracle-L -> RE: Space Manager vs. Live ReOrg vs TS ReOrg
I agree with Jesse.
Although Live Reorg would be a great tool, it was extremely COST INTENSIVE. I would love to be able to reorg tables with essentially no down time but, so far, the cost does not outweigh the benefit.
The nice thing with Space Manager is that it will create your DB scripts for you .... and then you can save them and re-use them the next itme those tables needed reorg. Even if you no longer have Space Manager. Either that, or you can let Space Manager schedule and run them for you in off hours.
Of course, my personal favorite is the standard DBA Set of Scripts that you run on your scheduled maintenance days. We get what we can done ... and the rest, until such time as the on-line reorg software is cost effective, waits for the next window.

>> Space Manager: Cheap, but needs downtime.
>> Live Reorg: Expensive, but no real downtime.
>> TS Reorg: Now owned by CA, so I probably won't even look at it. :)

Space Manager is an "offline" tool -- It creates a script that will create a new table, populate it, and replace the old table with it, and during this time the table is not accessible.
Live Reorg only has a "very short" window where the table is locked -- Quest says a few seconds -- while the table is reorg'd. And, while I haven't used it, I'm guessing that Live Reorg will not invalidate objects (like triggers) that have a dependency on the table being reorg'd, unlike Space Manager's brute force method.
Space Manager 3 is OK. v4 should be much nicer once it's out of beta (read: more stable). There are enough major bugs in v4 (easy to reorg a 500K index to a 500M index) that I'm going to wait for an "official" version. :)
Bottom Line:
Space Manager: Cheap, but needs downtime.
Live Reorg: Expensive, but no real downtime.
TS Reorg: Now owned by CA, so I probably won't even look at it. :)
Good luck!

My client and I are currently planning on re-orging some of our database - say about 90G out of a 120G database (2 schemas). We've identified 3 tools and are seeking feedback on the pros/cons of each option.
....
anyone?
Also, can anyone explain the difference between Space Manager and Live ReOrg? Both are marketed by Quest, making me wonder what, if anything, is the difference...
