The QUERY_REWRITE_INTEGRITY parameter specifies the degree to which Oracle will enforce integrity rules during a query rewrite: enforced, trusted, or stale tolerated. trusted: Oracle assumes the materialized view is current and allows rewrites using relationships that are not enforced by Oracle. enforced: This is the safest mode; Oracle doesn t use transformations that rely on unenforced relationships. This mode always uses fresh data, guaranteeing consistency and integrity. stale tolerated: Oracle will allow query rewrites using unenforced relationships.

This crucial initialization parameter specifies how Oracle s SQL statements are supposed to share cursors. The three possible values are forced, exact, and similar. You ll learn more about setting this parameter in 21. Default value: exact Parameter type: Dynamic. Both the ALTER SESSION and ALTER SYSTEM commands can be used to change the value.

Caution You have to be extremely careful when using the CURSOR_SHARING parameter. As you ll learn in 18, using the forced option will force Oracle to use bind variables, and thus will enhance your application performance. However, there are many caveats, and the wrong option for this parameter can hurt performance. If you re using a stored outline, CURSOR_SHARING = similar could cause problems in your application.

The DB_BLOCK_SIZE parameter sets the standard database block size (measured in bytes, such as 4096, which is a 4KB block size). The System tablespace and most other tablespaces use the standard block size. You set the standard block size from 2KB to 32KB (2, 4, 8, 16, or 32) in the DB_BLOCK_SIZE parameter. (Because the size is specified in bytes, the actual range for the DB_BLOCK_SIZE parameter is 2,048 32,768.) You can also specify up to four nonstandard block sizes when creating tablespaces. You have to carefully evaluate your application s needs before you pick the correct database block size. Whenever you need to read data from or write data to an Oracle database object, you do so in terms of data blocks. Also, you always should make the DB_BLOCK_SIZE value a multiple of your operating system s block size, which you can ascertain from your UNIX or Windows system administrator.
Remember that the data block is the smallest unit in the Oracle physical database structure. When you are Tip querying data, the rows aren t fetched individually; rather, the entire block in which the row resides is read into memory in one fell swoop.
If you re supporting data warehouse applications, it makes sense to have a very large DB_BLOCK_ SIZE something between 8KB and 32KB. This will improve database performance when reading huge chunks of data from disk. Large data warehouses perform more full table scans and thus perform more sequential data access than random access I/Os.
CHAPTER 9 CREATING AN ORACLE DATABASE
However, if you re dealing with a typical OLTP application, where most of your reads and writes consist of relatively short transactions, a large DB_BLOCK_SIZE setting would be overkill and could actually lead to inefficiency in input and output operations. Most OLTP transactions read and write a very small number of rows per transaction, and they conduct numerous transactions with random access I/O (index scans), so you need to have a smaller block size, somewhere from 2KB to 8KB. A large block size will hurt performance for most OLTP applications, as the database has to read large amounts of data into memory even when it really needs very small bits of information. Default value: 8192 (bytes) Parameter type: Static
