The database routinely checks new plans so as to evolve the SQL plan baselines, which involves changing a nonaccepted plan into an accepted plan and this part of the SQL plan baseline. As mentioned earlier, a nonaccepted plan must show superior performance to an accepted plan in order to be converted into an accepted plan in the baseline. If you re manually loading SQL plans, there is no need to formally evolve the plans, as every plan you load is automatically deemed an accepted plan. However, any plans that the database captures automatically must be formally evolved into the SQL plan baseline. You can evolve SQL plan baselines either by executing the EVOLVE_SQL_PLAN_BASELINE function or with the help of the SQL Tuning Advisor. The following example shows how to execute the EVOLVE_ SQL_PLAN_BASELINE function to add new accepted plans to the baseline. SQL> exec dbms_spm.evolve_sql_plan_baseline (sql_handle => '123456789111'); The example uses the SQL_HANDLE attribute to specify the plan for a specific SQL statement, but by ignoring this attribute, you can make the database evolve all nonaccepted plans in the database. You can also submit a list of SQL plans if you wish, by specifying the PLAN_LIST attribute. .net barcode reader sdk BarCode 4.0.2.2 - NuGet Gallery

The SQL Tuning Advisor evolves SQL plan baselines by automatically adding all plans for which you have implemented the advisor s SQL profile recommendations to the SQL plan baseline for a statement. You can limit the set of possible accepted plans for SQL statements by setting the FIXED attribute to YES for a SQL plan. When you fix a plan in a baseline, the optimizer prefers it to other nonfixed plans in the baseline, even if some of the other plans are actually cheaper to execute. The database stops evolving a fixed SQL plan baseline, but you can always evolve the baseline by adding a new plan to the baseline. The following query on the DBA_SQL_PLAN_BASELINES view shows important attributes of SQL plans in the baseline: SQL> SELECT sql_handle, sql_text, plan_name, fixed, autopurge FROM dba_sql_plan_baselines; origin, enabled, accepted, read barcode from image c#.net Asp.net barcode and qr code scanner | The ASP.NET Forums

Type coupling between a user-defined class and a platform class There is no way to completely eliminate the coupling between Class1 and the built-in classes and types, because the only way to perform standard console I/O in C# is via the System component. You could replace System.String with a user-defined string class, but this wouldn t eliminate any coupling because the effect would only be to change what Class1 is coupled to. You must accept the fact that the coupling between Class1 and the built-in classes is not dependent on bad design, and generally can t be avoided. The coupling that exists between a class and a built-in type is a special case of type coupling called platform type coupling, or simply platform coupling. All OO software incurs platform coupling, but the presence of this form of coupling doesn t typically reduce the quality of a software system. The assumption here is that the built-in components and types are stable and well tested; however, this might not always be the case. Java software used to be particularly susceptible to problems caused by platform coupling.
