Oracle 11g helps DBAs and developers with the capacity of viewing tables that have been added earlier on, encourages superior compression of different kinds of data, provides useful disaster recovery functions, and a lot more. Version 11g of Oracle Database incorporates built-in testing capabilities for changes along with other useful tools and features. Exceptions are capable of being traced back to the source in Oracle 10g.Oracle offers new SQL tuning recommendations with 10g.External tables can be used for unloading/ write/read data in 10g.Oracle 10g enables DBAs and developers to enqueue/dequeue in bulk with its new array-based advanced queuing tool in 10g.The evolution of Oracle data can now be viewed as a flashback version query in Oracle 10g.The auto-trace enhancement feature allows the use of DBMS_XPLAN for creating output for its explain plans in Oracle 10g release 2.Oracle now "fixes" DBMS_OUTPUT via new enhancements responsible for impacting dbms_output in the Oracle 10g release 2.Flashback restore points enable the capturing of a point in time for affecting flashback operations in release 2 of Oracle 10g.Dml error logging performance: The Release 2 of Oracle 10g features add-on performance characteristics of DML error logging.SQL plan enhancements: New Oracle 10g features allow for enhanced SQL performance investigations that are simpler to use.Pl/SQL optimization in Oracle 10g: The compiler optimization for much quicker PL/SQL optimization in Oracle 10g comes equipped with altogether new features about optimization bugs.The collect function in 10g: String aggregation can be used along with the newly introduced 10g COLLECT group function.Partition-wise dependencies possible in 10g release 2: Partitions can be modified without the requirement of invalidating dependent objects.Binding in-lists in 10g: The newly introduced MEMBER OF collection condition can be used as an alternative to IN-list binding in 10g.Oracle 10 g uses the Real Application Cluster (RAC) tool for installing a database across multiple servers. Individuals and corporations use Oracle 10g to automate different types of database management tasks. It offers several supporting grid computing features of the likes of automatic load balancing, resource sharing, etc. Along with other tools and features, Oracle 10g provides an application server and a database management system (DBMS). Oracle 10g is a computing product group belonging to Oracle's grid. They will be referred to through to SQL statements or as conditions in SQL statements. The hidden columns, after being assigned, will not be available through a generic query. Invisible columns are capable of being defined in a table in Oracle 12c. The hidden column feature is not present in Oracle 11g.

are some practical and useful enhancements introduced in Oracle 11g as new features.
#Oracle 10g release date Offline#
The online and offline methods of migrating table partitions and subpartitions can be easily implemented in oracle 12c. Table partitions and subpartitions movementĬomplex, time-consuming procedural logic has to be written by users for moving partitions/ subpartitions from one tablespace to another. Oracle 12c supports the In-memory aggregation concept. This version of Oracle does not support the In-memory aggregation concept. The table has to be added to the memory so that high-speed data can be accessed easily by the users.
#Oracle 10g release date full#
In-memory tables are used for full table scans and are supported by Oracle 11g. Big table cache provides significant performance benefits in terms of workloads that were earlier limited by I/O response time or throughput. The automatic big table caching serves to be a new concept in Oracle 12C. This new version of Oracle’s cache mechanism, referred to as big table cache, improves upon the performance metric for a full table scan. Additionally, it is not possible to implement Full Database caching in this version of Oracle. The In-memory parallel query statement does not work to perfection with multiple scans contended for the cache memory in Oracle 11g. LISTAGG and Nth_value are some new features and services in Oracle 11g.Īpprox_count_distinct () is a new feature in 12c it offers an approximation of distinct count aggregation. It does not consider the performance tuning of data in the given tables. Despite the creation of more than one index, only one column is capable of being used at any given point of time. Multiple indexes may be created on the same column. Additionally, the ideal index tool can be used in Oracle 11g. It is possible to create just a single index on any one table column.
