Interesting that “is_mixed_page_allocation†is true for design and still Phony for just about any consumer database. Would that be viewed as a “bug†since model is imagined to be used as being the template for almost any new consumer database?
any workaround you'll be able to suggest for this ? looks like there is nothing on oracle aid both and wasn't able to find just about anything superior(except your site) pointing in the direction of a possible Option but unsure how…
Exactly where I'm heading is always that I think by default oracle collects histograms (method_opt) automobile in 10g. I am gonna guess they may have histograms set on these partitions. If we clear away the histograms I do think we can easily take away the impact of the bind variable peaking ???
1 component to consider During this technique is numerous designers are typically restricted by their particular knowing. They could realize MySQL although not Oracle or SQL Server. They basically choose MySQL Considering that the other databases are much too unfamiliar.
In R—along with other languages with literal expression tuples—you can simulate the ternary operator with some thing similar to the R expression c(expr1,expr2)[one+ailment] (this idiom her latest blog is a little bit much more organic in languages with 0-origin subscripts).
BUT in tests, I learned I couldn't duplicate-paste the question from Grid Management into SQLplus, and execute it to achieve a similar target. Oracle doesn't see this as staying a similar question whatsoever, and will likely not make use of the profile established according to the SQLPlus operate.
ON controls whether the database can create Preliminary internet pages employing a mixed extent for the first eight web pages of a desk or index.
I have expertise activating sql_profiles that the sql tuning advisor constructed. I’ve witnessed your article about making a sql_profile from awr and / or perhaps the shared pool views.
The trace file should have slightly blurb at the highest declaring it located the Profile inside the SMB and then it's going to make an effort to validate it afterwards within the trace file. A seek for 10053 on This great site should convert up some samples of The sort of data obtainable from the trace data files.
Those people supplied Profiles typically Have a very evenly documented trace (OPT_ESTIMATE) that permits it to scale the optimizer estimates for many operations – basically it’s a fudge aspect. The trouble with this particular trace is, considerably from locking a strategy in place, it's locking an empirically derived fudge Consider location. This still leaves the optimizer with loads of overall flexibility In relation to selecting a plan. What's more, it sets up a typically developing predicament exactly where the fudge things prevent making feeling as the studies transform. So the observation that SQL Profiles have a tendency to bitter eventually.
(i.e. – following generating an Define you'll want to think about the hints to make sure they make sense, and then verify the statement essentially uses the Define, and afterwards confirm that it actually arrives up with the correct prepare through the use of All those hints, and so on…)
