By default, Oracle estimates the export job space requirements in terms of blocks. It simply takes your database block size and multiplies it by the number of blocks all the objects together will need. Here is an example of what you ll see in your log file (and on the screen): Estimate in progress using BLOCKS method . . . Processing object type SCHEMA_EXPORT/TABLE/TABLE_DATA Total estimation using BLOCKS method: 654 KB Since the space estimation in terms of blocks is the default behavior, you don t need to specify the ESTIMATE parameter during the export. However, if you have analyzed all your tables recently, you can ask the Data Pump Export utility to estimate the space requirements by using the statistics the database has already calculated for each of the tables. In order to tell the database to use the database statistics (rather than use the default BLOCKS method), you need to specify the ESTIMATE parameter in the following manner: ESTIMATE=STATISTICS Here s what you ll see in your log file when you use the ESTIMATE=STATISTICS parameter: Estimate in progress using STATISTICS method . . . Processing object type SCHEMA_EXPORT/TABLE/TABLE_DATA . estimated "SYSTEM"."HELP" Total estimation using STATISTICS method: 65.72 KB

While the ESTIMATE parameter is operative only during an actual export job, you can use the ESTIMATE_ONLY parameter without starting an export job. Listing 14-4 shows one such example. Listing 14-4.

Figure 2-7. The hierarchy of subscription models The four basic subscription models are channel, type, filter, and group. A channel denotes the physical or abstract construct through which notifications are sent to subscribers. A channel might be an outgoing procedure call, a network connection, a UML component port, or something else. Subscriptions by type are commonly used in direct-delivery EBSs developed with a component model (such as JavaBeans, .NET, or Delphi Object Pascal) that supports events or notifications as OO types. Filtered subscriptions use a filter to accept or reject notifications based on various criteria. A group represents a collection of subscribers that share the same subscription. Group subscriptions are useful when many subscribers are interested in getting the same notifications. The group would be associated to the proper channel or channels with the appropriate filters.

Connected to: Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - P tion With the Partitioning, OLAP, Data Mining and Real Application Testing optio FLASHBACK automatically enabled to preserve database integrity. Starting "SYSTEM"."SYS_EXPORT_SCHEMA_01": system/******** estimate_only=y Estimate in progress using BLOCKS method . . . Processing object type SCHEMA_EXPORT/TABLE/TABLE_DATA . estimated "SYSTEM"."REPCAT$_AUDIT_ATTRIBUTE" 64 KB . . . . estimated "SYSTEM"."SQLPLUS_PRODUCT_PROFILE" 0 KB Total estimation using BLOCKS method: 320 KB Job "SYSTEM"."SYS_EXPORT_SCHEMA_01" successfully completed at 11:20:16 C:\> Although the log indicates that the export job successfully completed, all the previous job really did was to estimate the space that you will need for the actual export job.

The Data Pump Export utility provides a way to initiate a network export Using the NETWORK_LINK parameter, you can initiate an export job from your server and have Data Pump export data from a remote database to dump files located on the instance from which you initiate the Data Pump Export job Here s an example that shows you how to perform a network export: $ expdp hr/hr DIRECTORY=dpump_dir1 NETWORK_LINK=finance DUMPFILE=network_exportdmp LOGFILE=network_exportlog In the example, the NETWORK_LINK parameter must have a valid database link as its value This means that you must have created the database link ahead of time This example is exporting data from the finance database on the prod1 server Let s say you have two databases, called local and remote In order to use the NETWORK_LINK parameter and pass data directly over the network, follow these steps: 1.

You can think of notification channels like television channels: Once you select a channel, you get all the programs broadcast on that channel. Event publishers can use any number of channels. If they use just one, then all notifications are sent on that one channel. More commonly, publishers define multiple channels and use an internal mapping algorithm to associate notifications to channels. Some publishers define a different channel for each type of possible notification. A channel denotes the physical or abstract construct through which event notifications leave the publisher. In direct-delivery models, it is the responsibility of the event publisher to establish a mapping between events and channels. In indirect-delivery models, the notification middleware might be responsible for establishing the mapping. A channel can provide notifications for a single event or a group of events, as shown in Figure 2-8, Figure 2-9, and Figure 2-10.
