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.
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 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.

Syntax for archecker utility commands

The archecker utility provides a command-line interface for restoring data from an archive. To use archecker, you must specify both a configuration file and a schema command file.

Table-level restore

Table 1. Options for the archecker command
Element	Description
-b	Provides direct XBSA access for backups created with .
-d	Deletes previous archecker restore files, except the archecker message log. For more information, see When to delete restore files.
-D	Deletes previous archecker restore files, except the archecker message log, and then exits. The -D option can be used with the -X option to delete previous restore files plus any table-level-restore working tables in the sysutils database. For more information, see When to delete restore files.
-f `cmdfile`	Specifies that archecker use the command file specified by `cmdfile`. This option overrides the value of the AC_SCHEMA configuration parameter. For more information, see Schema command file.
-i	Manually initializes the system.
-lphys,stage,apply	Specifies the level of logical restore: phys Starts a logical restore of the system, but stops after physical recovery is complete. The backed up logical logs must be available. stage After physical recovery is complete, extracts the logical logs from the storage manager and stages them in their corresponding tables, and starts the stager. apply Starts the applier. The applier takes the transactions stored in the stage tables and converts them to SQL and replays the operations. The default level of logical restore if -l is not listed is -lphys,stage,apply. You can specify any combination of the logical restore levels, separated with commas. Spaces are not allowed between -l and levels. For more information, see Manually control a logical restore.
-s	Prints a status message to the screen.
-t	Specifies ontape as the backup utility.
-v	Specifies verbose mode.
-X	Specifies a table-level restore.
-V	Displays HCL Informix® version information.
-version	Displays additional version information about the build operation system, build number, and build date for HCL Informix®.

When you use , you can use an command to access archecker information to verify a backup. For information on the syntax for this command, see onbar -v syntax: Verifying backups.
