yes, for few configurations only similar to MS SQL and Oracle. To reduce the downtime, you can do a system assessment and Requirements to configure everything in a single shot to reduce the downtimes..

>> you mean this section "Table 3. Configurable Database Configuration Parameters"  and this column "Auto" ? which means setting auto apply without restart ?

Yes, refer to column Cfg. Online in Table 3.

>> all version of DB2 can do it ?

Similar to other RDBMS, few configuration settings changes with version but most remains the same.

What I meant is that Even though restart is not required for majority of the configurations, if you don't want to have frequent downtime required then consolidate all changes together.. honestly, I've never seen any environment changing these kind of settings very frequently..

yeah. me neither , but just in case.

someone very "SMART" said MySQL is good but once use it, restart everyweek ! and any change in configuration need a restart.

I ask this just in case.
