The database server
Disk, memory, and process management
Virtual processors and threads
These topics describe virtual processors, explain how threads run within the virtual processors, and explain how the database server uses virtual processors and threads to improve performance.
Manage virtual processors
These topics describe how to set the configuration parameters that affect database server virtual processors, and how to start and stop virtual processors.
Shared memory
These topics describe the content of database server shared memory, the factors that determine the sizes of shared-memory areas, and how data moves into and out of shared memory.
Manage shared memory
Data storage
The database server uses physical units of storage to allocate disk space. It stores data in logical units. Unlike the logical units of storage whose size fluctuates, each of the physical units has a fixed or assigned size that is determined by the disk architecture.
Manage disk space
You can use several utilities and tools to manage disk spaces and the data that the database server controls.
Allocate disk space
This section explains how to allocate disk space for the database server.
Specify names for storage spaces and chunks
Chunk names follow the same rules as storage-space names.
Monitor storage spaces
You can monitor the status of storage spaces and configure how you are notified when a storage space becomes full.
Manage dbspaces
This section contains information about creating standard and temporary dbspaces with and without the default page size, specifying the first and next extent sizes for the tblspace
tblspace
in a dbspace when you create the dbspace, and adding a chunk to a dbspace or blobspace.
Manage blobspaces
This section explains how to create a blobspace and determine the blobpage size.
Manage sbspaces
This section describes how to create a standard or temporary sbspace, monitor the metadata and user-data areas, add a chunk to an sbspace, and alter storage characteristics of smart large objects.
Manage the plogspace
You create or move the plogspace with the
onspaces
utility or equivalent SQL administration API command.
Automatic space management
You can configure the server to add more storage space automatically when more space is required. You use space more effectively and ensure that space is allocated as necessary, while reducing out-of-space errors. You reduce the time required to manually monitor your spaces to determine which storage space might run out of free space. If you configure the server to automatically add space, you can also manually expand a space or extend a chunk.
Drop a chunk
Use the
onspaces
utility to drop a chunk from a dbspace.
Drop a storage space
Use
onspaces
or
to drop a dbspace, temporary dbspace, blobspace, sbspace, temporary sbspace, or extspace.
Creating a space or chunk from the storage pool
If your storage pool contains entries, you can create storage spaces or chunks from free space in the storage pool.
Returning empty space to the storage pool
You can return the space from an empty chunk or storage space to the storage pool.
Manage extspaces
Skip inaccessible fragments
Display databases
You can display the databases that you create with SMI tables
or
.
SMI tables

Monitor disk usage
Multitenancy
You can segregate data, storage space, and processing resources for multiple client organizations by creating multiple tenant databases in a single instance of .
Storage optimization
Data compression and consolidation processes can minimize the disk space that is used by your data and indexes.
Data compression and consolidation processes can minimize the disk space that is used by your data.
Load data into a table
Moving data with external tables
You can use external tables to load and unload database data.
Storage space encryption
Logging and log administration
Fault tolerance
High availability and scalability
A successful production environment requires database systems that are always available, with minimal if any planned outages, and that can be scaled quickly and easily as business requirements change.
Distributed data
Overview of automatic monitoring and corrective actions
You can use the SQL administration API, the Scheduler, and drill-down queries to manage automatic maintenance, monitoring, and administrative tasks.

Administrator's Reference
The
HCL OneDB™ Administrator's Reference
includes comprehensive descriptions of
HCL OneDB™
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.
DB-Access User's Guide
This publication describes how to use the utility to access, modify, and retrieve information from
HCL® OneDB®
database servers.
OneDB Explore
OneDB Explore
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 OneDB 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. OneDB Explore 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. OneDB Explore is the centralized hub for graphical monitoring, alerting, and administration of your Informix database servers.
Backup and Restore Guide
The
HCL OneDB™ Backup and Restore Guide
describes how to use the
HCL® OneDB®
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.
