Installing
These topics describe how to install HCL Informix® database servers, client products, and modules.
Administering
In addition to administering the database server, you can tune performance, replicate data, and archive data.
- System administration
  These topics contain concepts, procedures, and reference information for database and database server administrators to use for managing and tuning HCL Informix® database servers.
- Backup and Restore Guide
  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.
  - Overview of backup and restore
    These topics provide an overview of backup and restore concepts. They also provide information about planning for backup and restore operations.
  - ON-Bar backup and restore system
  - ontape backup and restore system
  - Backup and restore a Remote Secondary Server(RSS)
  - Integrated Backup Encryption
    These topics provide information about Integrated Backup Encryption.
  - HCL Informix® Primary Storage Manager
    HCL Informix® Primary Storage Manager is an application that manages storage devices used for backup and restore requests that are issued by . This storage manager supports both serial and parallel processing for backup and restore requests.

  - Backup and restore configuration parameter reference
  - Cloud Backup
    These topics provide information about storing and retrieving the backups directly to the ecosystem of selected cloud providers, namely Amazon S3 and Softlayer Object Storage.
  - Appendixes
    - Troubleshooting some backup and restore errors
      This appendix lists some error and informational messages that you can receive during a backup or restore, describes under what circumstances the errors might occur or the message might appear, and provides possible solutions or workarounds.
    - Migrate data, servers, and tools
      - Backing up before a database server or storage-manager upgrade
        Before you upgrade to a new version of the database server, you must perform a complete backup.
      - Upgrading a third-party storage manager
        If you upgrade a third-party storage manager vendors, do not remove the old storage manager until you verify that the new storage manager works for both backup and restore operations.
      - Changing storage-manager vendors
        If you change storage manager vendors, do not remove the old storage manager until you have proof that the new storage manager works for both backup and restore operations. You can use the old storage manager as a backup storage manager to use in case the new storage manager does not meet your needs.
      - Switching from ontape to ON-Bar
        You cannot back up data with ontape and restore it with , or conversely because the data storage formats and backup capabilities are different. However, you can back up data with ontape, prepare to use , and then back up with .
    - GLS support
      This appendix contains information about using Global Language Support (GLS) with .
- Enterprise Replication
  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.
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.

Switching from ontape to ON-Bar

You cannot back up data with ontape and restore it with , or conversely because the data storage formats and backup capabilities are different. However, you can back up data with ontape, prepare to use , and then back up with .

About this task

To switch from ontape to :

Procedure

Use ontape to perform a full backup.
Take the backup media offline to prevent possible reuse or erasure.
Configure the storage manager to be used with .
Configure your environment:
1. Set the configuration parameters that you use with and the storage manager.
2. If you use a storage manager other than the HCL Informix® Primary Storage Manager, create the sm_versions file with the storage-manager definition. The Informix® Primary Storage Manager does not use the sm_versions.std file.
Use (onbar -b or onbar -b -w) to perform a full backup.
Verify the backup with the onbar -v command.
