After you create the stored outlines, Oracle won t automatically start using them. You have to use the ALTER SESSION or ALTER SYSTEM statement to set USE_STORED_OUTLINES to TRUE. The following example uses the ALTER SYSTEM statement to enable the use of the stored outlines at the database level: SQL> ALTER SYSTEM SET use_stored_outlines=true; System altered. SQL> You can also set the initialization parameter USE_STORED_OUTLINES to TRUE, to enable the use of the stored outlines. Otherwise, the database won t use any stored outlines it has created. java qr code New QR Code Reader Library - DZone Mobile

If you use synchronous procedure calls to deliver notifications, the sender delivers the notification in succession to each subscriber, blocking during each delivery. The time it takes to deliver the notification completely to all subscribers is the sum of the processing times of all subscribers. Figure 8-23 shows the notification delivery sequence of A sending notifications to B and then to C. You can easily change the stored access paths while using the plan stability feature. You can use either the DBMS_OUTLN_EDIT package or OEM to perform the changes. javascript qr code generator svg yuriy-budiyev/code-scanner: Code scanner library for ... - GitHub

Changes such as database upgrades, or even minor changes such as adding or deleting an index, could affect SQL execution plans I explained the Oracle stored outlines feature earlier in this chapter as a way to preserve SQL execution plans to prevent performance deterioration when the database undergoes major changes such as a database upgrade Oracle recommends that you use the new feature called SQL Plan Management (SPM) to keep performance from being affected by major system changes SQL Plan Management preserves database performance under the following types of system changes: Database upgrades New optimizer version Changes in optimizer parameters Changes in system settings Changes in schema and metadata definitions Deployment of new application modules Although you can tune SQL statements using the SQL Tuning Advisor and ADDM, that s at best a reactive mechanism and requires the DBA to intervene SPM is designed as a preventative mechanism. qr code vcard generator javascript How to generate QR code with logo inside it? - Stack Overflow

15 Mar 2018 ... These-days, QR - code has become a tech fashion. There is a reason behind that, It's very easy to create and use it. So now let's see how we ... Figure 8-23. Delivering notifications synchronously It may be inefficient for the sender to wait all this time. To reduce the processing time, the sender could notify all the subscribers concurrently, using separate threads. While the immediate effect of concurrent delivery is a reduced delivery time, a side effect is the loss of predictability in the delivery order. If B and C send notifications to a subscriber D, the notifications may arrive at D in a different order with respect to the nonconcurrent delivery case, as shown in Figure 8-24. The database controls the evolution of SQL plans using the new SQL plan baselines, which are sets of efficient execution plans captured by the database over a period of time The database allows a new execution plan to become part of a SQL plan baseline for a statement only if the new plan doesn t cause a regression in performance The database uses only those execution plans that are part of a SQL plan baseline to execute SQL statements, and thus the database achieves the key goal of preserving database performance in the face of major system changes such as database upgrades The SPM comes in very handy when you re upgrading to Oracle Database 11g After you upgrade to Oracle Database 11g from, say, the Oracle Database 10g release, first leave the OPTIMIZER_FEATURES_ ENABLE parameter at 102. Once the SPM mechanism collects the execution plans and stores them as SQL plan baselines, you can switch to the 111 setting for the OPTIMIZER_FEATURES_ENABLE parameter This way, you ensure that you re using all the new capabilities of the 11g release, without compromising SQL performance: performance is safeguarded through the use of SQL plan baselines, which are similar in this regard to the stored outlines maintained by the database.. Under SQL Plan Management, the database maintains a plan history, which is a record of all SQL plans generated over time for a SQL statement by the optimizer. The optimizer uses the plan history to figure out the optimal execution plan for a statement. Not all plans in the plan history for a statement java qr code generator library Generate QR Code image from Java Program | Java Code Geeks ...
