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.
The Informix® Administrator's Reference includes 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.
Use the onspaces utility to manage the storage spaces in your database.
HCL Informix® includes utilities and applications that you can use to perform administrative tasks and capture information about configuration and performance.
The Informix® Administrator's Guide provides the information required to administer HCL Informix.
The Informix® database server utilities allow you to perform administrative tasks directly from the command line.
Use the finderr utility to view additional information on Informix® error messages. On UNIX™ and Linux™ platforms, the information appears on the command line. On Windows™ platforms, the information appears in the Error Messages program.
Use the genoncfg utility to expedite the process of customizing the default Informix® configuration file (onconfig.std) to the host environment and your planned usage of a database server instance.
Use the oncheck utility to check specified disk structures for inconsistencies, repair inconsistent index structures, and display information about disk structures.
Use the onclean utility to force a shut down of the database server when normal shut down with the onmode utility fails or when you cannot restart the server. The onclean utility attempts to clean up shared memory, semaphores, and stops database server virtual processes.
Use the oncmsm utility to start or shut down a Connection Manager, load a new configuration file into a Connection Manager to modify the Connection Manager's settings, or update the format of a configuration file.
Use the onconfig_diff utility to compare two onconfig files.
Use the ondblog utility to change the logging mode for one or more databases.
The oninit utility starts the database server.
Use the onkstash utility to create a password stash file for an existing PKCS#12 keystore.
The onlog utility displays the contents of a logical-log file, either on disk or on backup.
Use the onmode utility to change the database server operating mode and perform various other operations on shared memory, sessions, transactions, parameters, and segments.
Use the onparams utility to add or drop a logical-log file, change physical-log parameters, and add a new buffer pool.
Use the onpassword utility to encrypt and decrypt a password file. Connection Manager and Enterprise Replication utilities require a password file to connect to database servers over an untrusted network.
You use the ifxclone utility to create a server clone from a snapshot of an existing database server.
Run onspaces utility commands to manage your storage spaces.
Use the onspaces -c -d command to create a dbspace or a temporary dbspace.
Use the onspaces -c -P command to create a plogspace in which to store the physical log.
Use the onspaces -c -S option to create a sbspace or a temporary sbspace.
Use the onspaces -c -x option to create an extspace.
Use the onspaces -ch option to change the default specifications of a sbspace.
Use the onspaces -cl option to clean up stray smart large objects in sbspaces.
Use the onspaces -d option to drop a chunk in a dbspace, blobspace, or sbspace.
Use the onspaces -d option to drop a dbspace, blobspace, plogspace, sbspace, or extspace.
Use the onspaces -f option to specify the value of the DATASKIP configuration parameter on a dbspace level or across all dbspaces.
Use the onspaces -m option to start mirroring for a dbspace, blobspace, or sbspace.
Use the onspaces -r option to end mirroring for a dbspace, blobspace, or sbspace.
Use the onspaces -ren option to rename a dbspace, blobspace, sbspace, or extspace.
Use the onspaces -s option to change the status of a mirrored chunk in a dbspace, a non-primary chunk within a noncritical dbspace, a blobspace, or an sbspace.
The onstat utility reads shared-memory structures and provides statistics about the database server at the time that the command runs.
The Informix® DB-Access User's Guide describes how to use the DB-Access utility to access, modify, and retrieve information from Informix database servers.
The describes how to use the HCL Informix® to load and unload large quantities of data efficiently to or from Informix databases.
The Informix® Performance Guide describes how to configure and operate your HCL Informix database server to improve overall system throughput and to improve the performance of SQL queries.
The describes 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.
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.
The Informix® Backup and Restore Guide describes how to use the 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.
The HCL® Informix® Enterprise Replication Guide describes the concepts of data replication using Informix Enterprise Replication, including how to design your replication system, as well as administer and manage data replication throughout your enterprise.
