Informix V11.70 delivers functions, values and quality. It delivers newlevels of performance, availability, and autonomy that will help meet customer's modern business requirements and help partners grow with minimal complexity and lower computing costs.
Informix V11.70 offers:
* More Flexibility: Informix V11.70 offers more options and choices to scale capacity, and to better manage and utilize resources. Further, Informix V11.70 provides new interoperability with several open source tools, bringing a broad set of choices for application development.
* Higher Reliability: Informix V11.70 offers enhanced autonomics and greater automation including during failure recovery.
* Higher Performance: With Informix V11.70, business transactions run faster and analytic queries run up to 50% faster than before.
* Greater Efficiency: With the ability to better utilize existing hetergenous infrastructure, an automated task scheduler, higher performance and further reduced administration requirements, Informix V11.70 offers a higher level of efficiency.
New in Informix V11.70
New Informix grid capabilities take scalability, flexibility, resource utilization and workload management to new levels:
* Heterogeneous flexibility leverages existing resource investments and enables scaling beyond a single cluster: Different Informix clusters can be brought together enabling applications to see an entire cluster as a single node. Workloads can be managed and spread across different nodes within this heterogeneous environment. Administrators can dynamically add or drop Informix server nodes to meet changing workload requirements.
* Highly simplified management and administration with rolling upgrades: Nodes can be setup with a single click using OpenAdmin Tool or by a single command from the command line interface. Administrators have the flexibility to automatically replicate just schema changes or schema as well as data changes. The management can be performed at any node within this environment. The Informix Connection Manger in Informix V11.70 facilitates easy rolling upgrades.
* Massive, linear scalability: Administrators can now utilize resources spread across geographies to serve as nodes for linear scaling of application requirements.
* Seamless, transactional continuity during failover: With transactional survival capabilities, within an Informix grid, transactions can continue to run on an established Informix secondary server when a primary server fails.
Best-of-breed embeddability that gets more autonomous
* More autonomy for even less human and programmatic intervention: Informix V11.70
o Automated storage allocation for extending space when pre-determined thresholds are met , contributing to added self-maintenance
o Built-in support and automatic registration of extensions and advanced data types contributing to added self-configuration
o Standardization of alarm and error codes for application exception handling as well as automated scheduler tasks for CPU allocation, time-outs and error notifications
* Simplified Installation: Informix V11.70 introduces a platform independent installation process with a standardized approach.
Enhanced warehouse infrastructure that optimizes performance and lowers costs
* Better performance with faster query response times:
o Star join optimization that improves query execution speed
o Support for multi-index scans and push down hash joins
* Simplified management of growing warehouse needs
o Automatic lookup of tables and addition of table fragments as tables grow
o Automatic interval fragmentation of time-cyclic data using interval and list strategies
o Statistics by fragment level
Enhanced security management that can help improve efficiency in support of compliance and data protection efforts
* Higher granularity with auditing: With selective row-level auditing, customers can now choose which tables and operations they wish to audit and track.
* Enhanced authentication simplifies user administration
o Informix V11.70 offers centralized user administration that logically separates Informix user names from operating system users on which the Informix server is running.
o Informix V11.70 introduces Trusted Context feature that allows middle tier applications to specify trusted users providing the ability to reuse connections between users after authentication.
o Informix V11.70 provides the capability to protect data at rest with Encryption Expert feature that encrypts Informix data on disk.
Application development enhancements for increased developer productivity and serving modern business needs
* Can mean faster time to market for applications and increased developer productivity: Informix V11.70 introduces Stored Procedure Language debugging API that enables integration with industry-lading application debuggers.
* Increase adoption and deployment of SOA applications, which can lower cost: With Informix V11.70, multiple instances of Informix can attach to a remote IBM Websphere MQ server.
* Increased options and easier enablement of open source applications with Informix:
o Increased support for industry standard SQL
o Increased interoperability with open source software
o New SQL syntax for easier porting of open source applications to Informix
* Improved developer productivity with IBM Optim Development Studio
o Enables faster development and testing of SQL queries, stored procedures and Web Services using IBM Optim Development Studio
o Visual analysis of SQL statements, execution and performance with IBM ODS
* Richer, faster Web 2.0 application development with included mashup functionality
o Rapid assembly and deployment of mashup applications
o Rapid development and deployment of visual BI reports

IBM真搓啊，developer,express版本还是TimeLimited,本来想下个玩玩，有时间限制就懒得搞了。 原来11.5的都没有时间限制的，不知道哪个神经又搭错了。
