Informix OnLine

• High Performance
  IBM Informix® OnLine and OnLine Extended Edition, Version 5.2 achieve their high performance by establishing efficient data storage methods for fast data access, buffering data in memory to minimize disk access, utilizing multiprocessor features to enable simultaneous access by different processors, determining the most efficient search strategy automatically,and just recently supporting greater than 2 GB chunk offsets and pipe connectivity.
• Data Consistency
  Ensures that data is kept correct and consistent despite the large numbers of user accesses.
  

  IBM Informix OnLine and OnLine Extended Edition do this via several built-in mechanisms--at the systems and transaction levels--without posing any unnecessary barriers to information access and smooth performance.

• Distributed Client/Server Capability
  Allows you to transparently manipulate multiple databases at different locations. And with a two-phases commit protocol, you'll know that transactions interacting with multiple database servers are always kept in consistent state.
• Ease of Administration
  Administrator maintains high levels of performance and backup and recovery plans by monitoring daily activities and adjusting parameters as needed.
• Support for pipe connectivity
  This feature allows the Rapid Application Development (RAD) tools -- such as Informix 4GL and Informix SQL 7.31 or later -- to use pipes to communicate with OnLine Extended Edition 5.20 servers running on the same machine, instead of having to use a TCP/IP loopback connection with Informix Star or Informix Net. Customers who use OnLine Extended Edition 5.20 with the 7.31 tools can save the cost of purchasing Informix Net or Informix Star separately. Customers who are still using the version 4.x tools can upgrade to OnLine Extended Edition 5.20, and take advantage of the many language enhancements in the version 7.31 tools.
• Support for greater than 2GB chunk offsets
  This performance-related feature allows customers to utilize the entire capacity of the disk drive without partitioning it into smaller logical devices and employing logical volume managers. This capability increases the return-on-investment (ROI) by maximizing the use of the latest computer hardware with greater storage capacity -- saving the cost of purchasing third-party storage management solutions.
• Support for Linux
  Linux is a major platform for database and application servers. IBM Informix OnLine Extended Edition for Linux provides a proven, easy-to-manage database offering high performance, stability and reliability. Together Linux and IBM Informix OnLine Extended Edition for Linux are the building blocks for success in e-business.

Informix OnLine is an easy-to-use, embeddable database server providing superior online transaction processing, data integrity, and multimedia data management capabilities for low-to-medium workloads. The lists below provide the system requirements for each of the editions.
