New partition pruning features of 10g

Filed under: Oracle 10g New Features,Oracle Business Intelligence,Oracle Performance — H.Tonguç Yılmaz @ 3:49 pm

As I mentioned earlier I started working with our data warehouse team on their migration project; Planning and Testing the 9iR2 to 10gR2 migration of our XXX Tb DWH

I will be testing Oracle’s 10gR2 features for performance. So before tests in details, I also wanted to mention some important very large Oracle database init.ora 10g parameters additional to ASM and CBO configurations I already mentioned; Listing 177a – Some important very large Oracle database init.ora 10g parameters

During some initial tests I experienced new partition pruning features of 10g; “PARTITION RANGE OR”-“KEY(OR)” and “PARTITION RANGE MULTI-COLUMN”-“KEY(MC)” access paths; Code Listing 177b – New partition pruning features of 10g

These tests will be really cool :)

Testing Information : the scripts mentioned are tested on Oracle Database 10g Enterprise Edition Release
