Fetch modes allow us to change this behavior to optimize application performance when needed. Entity fetch modes We briefly mentioned fetch modes in previous chapters but haven t discussed them in great detail. Discussing entity retrieval is an ideal place to fully explore fetch modes. As we suggested, the EntityManager normally loads all entity instance data when an entity is retrieved from the database. In ORM-speak, this is called eager fetching, or eager loading. If you have ever dealt with application performance problems due to premature or inappropriate caching, you probably already know that eager fetching is not always a good thing. The classic example we used in previous chapters is loading large binary objects (BLOBs), such as pictures. Unless you are developing a heavily graphics-oriented program such as an online photo album, it is unlikely that loading a picture as part of an entity used in a lot of places in the application is a good idea. Because loading BLOB data typically involves long-running, I/O-heavy operations, they should be loaded cautiously and only as needed. In general, this optimization strategy is called lazy fetching. JPA has more than one mechanism to support lazy fetching. Specifying column fetch-mode using the @Basic annotation is the easiest one to understand. For example, we can set the fetch mode for the picture property on the Item entity to be lazy as follows:

The data access functionality gets its own layer for two reasons Delegating the persistence functionality into its own layer protects the system from change and keeps tests quick to run and easy to write One of the primary reasons for abstraction in object-oriented systems is to isolate sections of the applications from change The data access functionality is no different, and it is designed to isolate the system from changes in the persistence mechanisms As an example, a business requirement change might force all user accounts to be stored inside an LDAP-compliant directory instead of a relational database While this might happen rarely, abstracting the persistence operations behind a single interface makes this a low-impact change for the system A more likely scenario is a change in the data access layer s implementation and libraries.

does. This script is dropping and re-creating a table called SESS_STATS. If your schema already has such a table, you ll probably want to use a different name!

A SELECT statement generated by the find method to retrieve Item entities would not load data from the ITEMS.PICTURE column into the picture field. Instead, the picture data will be automatically loaded from the database when the property is first accessed through the getPicture method. Be advised, however, that lazy fetching is a double-edged sword. Specifying that a column be lazily fetched means that the EntityManager will issue an additional SELECT statement just to retrieve the picture data when the lazily loaded field is first accessed. In the extreme case, imagine what would happen if all entity data in an application is lazily loaded. This would mean that the database would be flooded with a large number of frivolous SELECT statements as entity data is accessed. Also, lazy fetching is an optional EJB 3 feature, which means not every

The other script is called watch_stat.sql, and for this case study, it uses the MERGE SQL statement so we can initially INSERT the statistic values for a session and then later come back and update them without needing a separate INSERT/UPDATE script: merge into sess_stats using ( select a.name, b.value from v$statname a, v$sesstat b where a.statistic# = b.statistic# and b.sid = :sid and (a.name like '%ga %' or a.name like '%direct temp%') ) curr_stats
