In addition to administering the database server, you can tune performance, replicate data, and archive data.
The describes 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.
Welcome to the documentation for HCL Informix® 15.0.0 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 modules.
These topics contain concepts, procedures, and reference information for database and database server administrators to use for managing and tuning HCL Informix® database servers.
The HCL® Informix® Backup and Restore Guide describes how to use the HCL Informix 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.
HCL Informix® Enterprise Replication generates and manages multiple copies of data at one or more sites, which allows an enterprise to share corporate data throughout its organization.
Before you set up your replication system, plan how to include Enterprise Replication into your database server environment, design your database schema by following Enterprise Replication requirements, and then design your replication system between database servers.
After you design your replication system, you define it and start replication.
You use the cdr utility to configure and control from the command line on your UNIX™ or Windows™ operating system.
You can use configuration parameters and environment variables to configure the behavior of .
Grid routines are used to create and maintain the grid and to administer servers in the grid by propagating commands from a source server to all other servers in the grid.
Enterprise Replication routines used to control if a replicated transaction is recaptured.
You can monitor and debug Enterprise Replication activity using onstat -g commands.
These tables in the syscdr database contain progress information about consistency checking and synchronization operations.
The system-monitoring interface (SMI) tables in the sysmaster database provide information about the state of the database server. Enterprise Replication uses the following SMI tables.
This appendix contains simple examples of replication using the command-line utility (CLU).
Data sync warning and error messages describe problems with replicated transactions.
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.
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 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.
