IBM Informix Flexible Grid: Extending Data Availability

In this IBM® Redbooks® publication, we focus on, and provide an overview of, the high availability and Enterprise Replication features of IBM Informix® 11.70. Informix provides solutions for making data highly available in the MACH11 cluster. The components of the MACH11 cluster include High Availability Data Replication (HDR), Shared Disk Secondary (SDS), and Remote Secondary Standby (RSS) servers. Enterprise Replication (ER) provides a means of selectively replicating data between systems in near real time. The Informix Flexible Grid eliminates the administrative complexity of ER. Flexible Grid provides the ability to automatically create database objects, such as tables, indexes, and stored procedures, on all nodes within the grid as a single operation. These enhanced Enterprise Replication features provide solutions for those customers requiring reliable and quick dissemination of data across a global organization. There is also enhanced capability for customers requiring High Availability Disaster Recovery, in the form of the ability to resend primary server indexes to secondary servers without requiring a rebuild of the index on the primary server. Capabilities such as these enable faster, easier, and more reliable distribution and high availability of data, resulting in improved access and use throughout the enterprise.

Embedding IBM Informix

In this IBM® Redbooks® publication, we discuss and describe the capabilities for embedding Informix® into applications and software. We introduce the technological architecture and describe several of the functions and features that support Informix as a robust and powerful embeddable DBMS. Many of these features are unique in the industry today, enabling clients to create a business advantage. The Informix database server can support the requirements of an embeddable DBMS, and is doing so for many companies today. The low administration requirements of the Informix database server enable clients to deploy thousands of Informix instances, embedded in applications in locations where there are no technical resources to support the database. The real requirement is for applications with embedded databases that require little or no administration, take minimum storage resources, have excellent performance, and are highly reliable. As a mature and reliable DBMS, the Informix database server works well with small, growing, and large databases, and meets the key requirements for embedded databases, which include the ability to execute without needing any configuration or other DBA administrative activities, and the flexibility to work on all of the platforms commonly used in the marketplace today.
