In addition to administering the database server, you can tune performance, replicate data, and archive data.
These topics contain concepts, procedures, and reference information for database and database server administrators to use for managing and tuning HCL Informix® database servers.
These topics describe the Simple Network Management Protocol (SNMP) and the software that you need to use SNMP to monitor and manage HCL Informix® database servers and databases.
The HCL Informix® implementation of SNMP lets database administrators monitor Informix database servers and databases.
Welcome to the documentation for HCL Informix® 15.0 and related client tools and products.
HCL Informix® is a fast and scalable database server that manages traditional relational, object-relational, and dimensional databases. Its small footprint and self-managing capabilities are suited to embedded data-management solutions.
These topics describe how to install HCL Informix® database servers, client products, and DataBlade® modules.
HCL Informix® includes utilities and applications that you can use to perform administrative tasks and capture information about configuration and performance.
These topics provide the information required to administer HCL Informix®.
These topics include comprehensive descriptions of HCL Informix® configuration parameters, the system-monitoring interface (SMI) tables in the sysmaster database, the syntax of database server utilities such as onmode and onstat, logical-log records, disk structures, event alarms, and unnumbered error messages.
This publication describes how to use the DB-Access utility to access, modify, and retrieve information from HCL® Informix® database servers.
These topics describe how to use the HCL Informix® High-Performance Loader (HPL) to load and unload large quantities of data efficiently to or from Informix databases.
These topics describe how to configure and operate your HCL Informix® database server to improve overall system throughput and to improve the performance of SQL queries.
This section provides a brief introduction to Simple Network Management Protocol (SNMP).
You can configure an SNMP Network Manager to notify you when a specific event occurs.
You can issue a one-time data request to compare the configuration parameters of two database servers. You can issue periodic data requests to provide statistical information for assessing database performance or resource allocation.
All the information that OnSNMP provides is available from other sources, such as the system catalog tables, the sysmaster and sysutils databases, dbaccess calls, and the onstat utility.
The SNMP standard has two versions: SNMPv1 and SNMPv2.
The architecture for the HCL® Informix® implementation of SNMP depends on your operating system.
HCL Informix® products include a Global Language Support (GLS) feature, which lets you work with languages that use code sets other than the standard English code set. However, the SNMP protocols that OnSNMP supports (SNMPv1 and SNMPv2) do not recognize these different code sets.
This section describes the types of MIBs and the types of MIB objects that the HCL Informix® database server uses.
As a background task, OnSNMP periodically updates the contents of MIB tables that it derives from catalog information. The refresh control value determines the amount of time that OnSNMP spends refreshing these MIB tables versus the amount of time that it spends responding to queries from the master agent.
This section lists the files that are typically installed for the HCL® Informix® implementation of SNMP on UNIX™ and Windows™.
An SNMP Network Manager hides most of the structures of the Management Information Base (MIB). However, an understanding of this structure can help you comprehend the information that an SNMP Network Manager displays.
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.
These topics describe how to use the HCL® 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.
These topics describe the concepts of data replication using HCL Informix® Enterprise Replication, including how to design your replication system, as well as administer and manage data replication throughout your enterprise.
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.
You can use the HCL Informix® implementation of client APIs to develop applications for Informix database servers.
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.
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.
In addition to designing and implementing Informix® dimensional databases, you can use tools to create data warehouse applications and optimize your data warehouse queries.
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.
You can use the popular JSON-oriented query language created by MongoDB to interact with data stored in HCL Informix®.
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.
You can use the HCL Informix® implementation of the SQL language to develop applications for Informix database servers.
Several troubleshooting techniques, tools, and resources are available for resolving problems that you encounter in your HCL Informix® database server environment.
