      - Overview of Utilities
        The Informix® database server utilities allow you to perform administrative tasks directly from the command line.
        Obtaining utility version information
        Use the -V and -version options of many Informix® command-line utilities to obtain version, primarily for debugging.
        Setting local environment variables for utilities (UNIX)
        On UNIX™ operating systems, you can start certain utilities without setting local environment variables in your shell environment. You can set local environment variables in the onconfig file. When you run the command to start the utility, use the -FILE option to point to the onconfig file.

      - The finderr utility
        Use the finderr utility to view additional information on Informix® error messages. On UNIX™ and Linux™ platforms, the information appears on the command line. On Windows™ platforms, the information appears in the Error Messages program.
      - The genoncfg Utility
        Use the genoncfg utility to expedite the process of customizing the default Informix® configuration file (onconfig.std) to the host environment and your planned usage of a database server instance.
      - The oncheck Utility
        Use the oncheck utility to check specified disk structures for inconsistencies, repair inconsistent index structures, and display information about disk structures.
      - The onclean utility
        Use the onclean utility to force a shut down of the database server when normal shut down with the onmode utility fails or when you cannot restart the server. The onclean utility attempts to clean up shared memory, semaphores, and stops database server virtual processes.
      - The oncmsm utility
        Use the oncmsm utility to start or shut down a Connection Manager, load a new configuration file into a Connection Manager to modify the Connection Manager's settings, or update the format of a configuration file.
      - The onconfig_diff utility
        Use the onconfig_diff utility to compare two onconfig files.
      - The ondblog utility
        Use the ondblog utility to change the logging mode for one or more databases.
      - The oninit utility
        The oninit utility starts the database server.
      - The onkstash Utility
        Use the onkstash utility to create a password stash file for an existing PKCS#12 keystore.
      - The onkstore Utility
      - The onlog utility
        The onlog utility displays the contents of a logical-log file, either on disk or on backup.
      - The onmode utility
        Use the onmode utility to change the database server operating mode and perform various other operations on shared memory, sessions, transactions, parameters, and segments.
      - The ON-Monitor Utility
      - The onparams Utility
        Use the onparams utility to add or drop a logical-log file, change physical-log parameters, and add a new buffer pool.
      - The onpassword utility
        Use the onpassword utility to encrypt and decrypt a password file. Connection Manager and Enterprise Replication utilities require a password file to connect to database servers over an untrusted network.
      - The ifxclone utility
        You use the ifxclone utility to create a server clone from a snapshot of an existing database server.
      - The onspaces utility
        Use the onspaces utility to manage the storage spaces in your database.
      - The onstat utility
        The onstat utility reads shared-memory structures and provides statistics about the database server at the time that the command runs.

It provides critical performance management capabilities, monitoring how key performance metrics are changing over time and tracking how efficiently Informix is running your workload even when you’ve stepped away from your screen. Its monitoring system feeds directly into a customizable alerting system so you can be immediately alerted via email, Twilio, or PagerDuty whenever an issue occurs on one of your Informix database server instances. InformixHQ is designed to be scalable to efficiently manage and monitor as many Informix database server instances as you need. Moreover, it's a tool that can be shared by the DBAs, the app developers, the ops engineers, and management and accessed from any desktop, laptop, or mobile device. InformixHQ is the centralized hub for graphical monitoring, alerting, and administration of your Informix database servers.
- Backup and Restore Guide
  These topics describe how to use the Informix® ON-Bar and ontape utilities to back up and restore database server data. These utilities enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.
- Enterprise Replication
  These topics describe the concepts of data replication using Informix® Enterprise Replication, including how to design your replication system, as well as administer and manage data replication throughout your enterprise.
Migrating and upgrading
You can upgrade to the 14.10 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. The resources that are external to the information center are marked as such.
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.
