InformixHQ Guide
InformixHQ is a modern web console for visualizing, monitoring, and managing your Informix server instances. It is purpose built for ease-of-use, scaling out, and optimizing DevOps needs. 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.

Migrating and upgrading
You can upgrade to the 15.0.0 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. 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.

Starting the InformixHQ Server

This topic provides a brief tutorial to help you get started with InformixHQ Server.

Locate the informixhq-server.jar and the monitoring-server.log4j.xml file in the $INFORMIXDIR/hq directory of your Informix database server installation.
Create an InformixHQ server configuration file. You can refer to the $INFORMIXDIR/hq/monitoring-server-example.properties file as an example.
Optionally, edit the monitoring-server.log4j.xml file to configure logging in the InformixHQ.
Note: By default InformixHQ runs on 8080 port. For more information, see InformixHQ server configuration.
Start the InformixHQ server using the following command:
```
 java -jar informixhq-server.jar monitoring-server.properties &
```
where monitoring-server.properties is the name of the InformixHQ server configuration file.
Note: Staring from 14.10.xC4 onwards, you can start the server using an alternate method. For more information on this, see Starting the InformixHQ Server and the Agent on Windows and Starting the InformixHQ Server and the Agent on Linux.
Sample output after starting the InformixHQ server with monitoring-server.log4j.xml:

When the InformixHQ server is started for the first time, a user with system administrator privileges for InformixHQ is created with the username and password as admin.
Using a web browser, go to the InformixHQ UI at http://localhost:8080/ and login with the user and password admin. On first login, you will be prompted to reset your password.
Note: We strongly recommend users to use a secured connection i.e. SSL while starting InformixHQ Server. To know how to configure it, see InformixHQ setup as Secured Server (SSL).
Once logged in, click Add Server to add an Informix server that you want to monitor.
