Self-tuning in Mimer SQL

Self-tuning in Mimer SQL

(OP)
Hi!
I've been reading the documentation of Mimer SQL, and I found very interesting the fact that they have so few parameters for tuning. How did they do that? Why does Oracle and SQL Server make us work so hard instead?
thanks in advance

RE: Self-tuning in Mimer SQL

I think this has been a general design philosophy of the Mimer system. To really have ease of use, you do not want parameters that are hard to understand the consequences of (in particular if you have production systems with many different applications running).

Also, this is something you have to build into a product to begin with, and not something that can easily be fixed up afterwards.

RE: Self-tuning in Mimer SQL

Ok, I agree that too many parameters to tune is not the idea. What I would like to know is if they are really self-tuning the system, or if they just configured it for the must regular cases, (which I don't find a bad idea at all for little-medium enterprises)?

RE: Self-tuning in Mimer SQL

In many systems there is a parameter to set the size of the transaction log (or rollback segement). In Mimer the corresponding structure is the commit set in TRANSDB. The commit set in Mimer dynamically grows and shrinks depending on transaction load. The system tries to keep it small to keep down restart times in case of a machine crash.  No intervention is ever necessary!

I think this is a good example of a self-tuning feature!
