Oracle 11g R2 adds a powerful new tool that can be detected in the application of any version of database objects, not all database objects to support version management, but private synonyms, views, and almost all of the PL / SQL objects, including stored procedures, functions, types, body types, packages, package bodies and triggers, version management of the real benefit is to simplify the deployment of a modified version of the application code to the production database, if the deployment of a series of errors encountered can be easy to roll back all of the objects to the previous version.

The previous article, I studied in depth the new features of Oracle 11g Certification "Flashback Data Archive (Flashback Data Archive, FBDA)", which is also known as "all recall (Total Recall)", only capture changes data, such data on a particular object, they constitute the FBDA, when the user through the Flashback Versions Query (Flashback Versions query) when the history of the lookup table, Oracle will be directly from the database to return UNDO tablespace recent changes in the data returned from the FBDA older data. Oracle has a current certification exams are very popular subjects 1Z0-144.

Although this feature is good, but in earlier versions, there are many restrictions, including add, modify, rename, delete table column, truncate table, modify table constraints, and modify the partition table partition specification, Oracle Certification, these all without limitation, the DDL for more complex operations, such as the use DBMS_REDEFINITION package has been stored FBDA redefining the basis of the table, Oracle 11g R2 provides a new DBMS_FLASHBACK_ARCHIVE packages, stored procedures DISASSOCIATE_FBA the underlying table will be separated from the FBDA, Once the requested changes are made, stored procedures will be used to re-associate REASSOCIATE_FBA the table and modify the underlying table.

In previous versions, use the CREATE TABLE statement to create the table, will also automatically create a table of the initial segment, starting from Oracle 11gR2, change the default behavior, create a table will not create the initial section, until there are data inserted into the table. In addition, any reliance on the table index or LOB segments can not be created until there is data insertion will be created, the table SEGMENT CREATION DEFERRED storage attribute specifies the default behavior, but you can use the SEGMENT CREATION IMMEDIATE property covered it.

Oracle 11g R2 Oracle 10g has continued since the admirable self-management, self-adjusting, self-healing features, this new version offers many new features, some are late features, some innovations, Oracle DBA can make use of These new features improve work efficiency, to become a real "information engineers." I believe you need a professional website Testinside help. Exam Testinside the same time there are other certification ,220-701 is a non-Oracle certification exams.
