High availability and scalability
A successful production environment requires database systems that are always available, with minimal if any planned outages, and that can be scaled quickly and easily as business requirements change.
Connection management through the Connection Manager
Connection Managers can control automatic failover for high-availability clusters, monitor client connections and direct requests to appropriate database servers, act as proxy servers and handle client/server communication, and prioritize connections between application servers and the primary server of a high-availability cluster. Connection Managers support high-availability clusters, replicate sets, server sets, and grids.
Configuration examples for connection management
The following examples show steps for setting up connection management for various connection units and various systems.
Example: Configuring for an SSL connection
This example shows the steps to configure CM to listen for SSL connections from database clients.

      - Strategies for high availability and scalability
        HCL Informix® database software can be customized to create the appropriate high availability and scalability solution to match your business goals and environment.
      - High-availability cluster configuration
      - Cluster administration
      - Connection management through the Connection Manager
        Connection Managers can control automatic failover for high-availability clusters, monitor client connections and direct requests to appropriate database servers, act as proxy servers and handle client/server communication, and prioritize connections between application servers and the primary server of a high-availability cluster. Connection Managers support high-availability clusters, replicate sets, server sets, and grids.
        Configuring connection management
        To configure connection management, you must install software, set environments and connectivity information, create Connection Manager configuration files, and run the oncmsm utility.
        Monitoring and troubleshooting connection management
        Tools are available to monitor connection management, and help you diagnose potential problems.
        Strategies for increasing availability with Connection Managers
        You can increase the resiliency of your client/server communication environment.
        Configuration examples for connection management
        The following examples show steps for setting up connection management for various connection units and various systems.
        Example of configuring connection management for a high-availability cluster
        This example shows steps that are required to configure connection management for a high-availability cluster.
        Example of configuring connection management for a grid or replicate set
        You can use a Connection Manager to route client connections for the replication servers of a grid or replicate set.
        Example of configuring connection management for a high-availability replication system
        You can use a Connection Manager to route client connections for the participants of a replicate set and to control failover for high-availability clusters that participate in Enterprise Replication.
        Example: Configuring connection management for untrusted networks
        This example shows steps that are required to configure connection management for an untrusted network.
        Example: Configuring for prioritizing connections and network monitoring
        You can install Connection Managers on the hosts of application servers, and then prioritize the connections between specific application servers and the primary server of a high-availability cluster. This configuration allows the highest priority application server to maintain its connection to the cluster's primary server if a portion of the network fails.
        Example: Configuring for an SSL connection
        This example shows the steps to configure CM to listen for SSL connections from database clients.
        Example: Using the OpenSSL encryption library
        This example shows the steps to configure CM to listen for SSL connection using the OpenSSL encryption library.
        Configuring a CM to connect to Oninit using SSL
        Configuring a client to connect to a CM using SSL
        A client can be configured to connect to a CM via SSL by following the same steps used to configure a client to connect to an Informix server via SSL. In this case the CM acts like a server. Follow the steps in Configuring a client for SSL connections at Configuring a client for SSL connections.
      - Cluster failover, redirection, and restoration
        To maintain availability, you must plan for the failover of primary servers, redirecting client connections from unavailable servers, and restoring the cluster to its original configuration after a failure.

Migrating and upgrading
You can upgrade to the 15.0 release of HCL Informix® or migrate from other database servers to Informix. Upgrading is an in-place migration method that uses your existing hardware and operating system software. Some changes to the Informix database server can affect upgrading from a previous release.
Client APIs and tools
You can use the HCL Informix® implementation of client APIs to develop applications for Informix database servers.
Embedding Informix®
When you embed HCL Informix®, you can use enterprise-class high-availability and high performance with embeddability features such as easy programmability, a small disk and memory footprint, and silent deployment.
Extending Informix®
Beyond standard relational database objects, HCL Informix® can be extended to handle specialized data types, access methods, routines, and other objects. Informix includes many built-in extensions that are fully integrated in the database server. Informix also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for Informix.
Data warehousing
In addition to designing and implementing Informix® dimensional databases, you can use tools to create data warehouse applications and optimize your data warehouse queries.
Designing databases
The first step in creating a relational database is to construct a data model, which is a precise, complete definition of the data you want to store. After you prepare your data model, you must implement it as a database and tables. To implement your data model, you first select a data type for each column and then you create a database and tables and populate the tables with data. You can also implement fragmentation strategies and control access to your data.
JSON compatibility
You can use the popular JSON-oriented query language created by MongoDB to interact with data stored in HCL Informix®.
Security
You can secure your Informix® database server and the data that is stored in your Informix databases. You can encrypt data, secure connections, control user privileges and access, and audit data security.
SQL programming
You can use the HCL Informix® implementation of the SQL language to develop applications for Informix database servers.
Troubleshooting HCL Informix®
Several troubleshooting techniques, tools, and resources are available for resolving problems that you encounter in your HCL Informix® database server environment.
