Home -> Community -> Mailing Lists -> Oracle-L -> performance comparision between LMT and DMT
Hi:
We have several oracle 8173 dbs on Solaris 2.8. Recently I was planning to
move all dictionary managered tablespace to locally-managered tablespace
(except SYSTEM ts), because there are many advantages using lmt as I read.
Today I did the following on a test db and here is what I did and found:
The import run successfully and the whole time was 5 hours and 40 minutes. This is about 35 minutes longer than the time it took last week!
The only thing different was that the old tbs were NOT lmt, the dump file are basically the same, not much data change and there is no other stuff running on the machine. So my question is that if this is normal or I miss something here? Another questions is that from your experience how much improvement in terms of performance did you see after you convert dmt to lmt?
