Automatic tuning of db_file_multiblock_read_count

The combination of your db_block_size and the setting for db_file_multiblock_read_count determine the "real" read sizes for an Oracle database, and prior to Oracle 10g Release 2, setting the db_file_multiblock_read_count was tricky. 

When you implement multiple blocksizes you should set your db_block_size based on the size of the tablespace where your large-object full-scans will be occurring. Remember, the parameter db_file_multiblock_read_count is only applicable for tables/indexes that are full scanned.

The value of db_file_multiblock_read_count can have a significant impact on the overall database performance and it is not easy for the administrator to determine its most appropriate value.

Spot hidden Oracle performance trends!

Using the principles of decision support systems technology, BC has developed an important new Oracle tuning tool, Ion for Oracle. Ion quickly isolates the reports on the important optimization issues, separating the wheat from the chaff like no other performance tuning software.

After several years of hard work, Ion for Oracle is finally available for general release. Ion is unlike any other Oracle tool on the market, a tool that encapsulates expert techniques to allow a DBA to quickly visualize important trends and signatures.

Predictive analytics is the key to repairing Oracle problems before they cripple your database, and I created Ion for Oracle to allow any DBA to quickly identify changing workloads and unobtrusive patterns of data access. To try Ion for free, see here:
