    - Administrative Utilities
      - Overview of Utilities
        The Informix® database server utilities allow you to perform administrative tasks directly from the command line.
      - The finderr utility
        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.
      - The genoncfg Utility
        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.
      - The oncheck Utility
        Use the oncheck utility to check specified disk structures for inconsistencies, repair inconsistent index structures, and display information about disk structures.
      - The onclean utility
        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.
      - The oncmsm utility
        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.
      - The onconfig_diff utility
        Use the onconfig_diff utility to compare two onconfig files.
      - The ondblog utility
        Use the ondblog utility to change the logging mode for one or more databases.
      - The oninit utility
        The oninit utility starts the database server.
      - The onkstash Utility
        Use the onkstash utility to create a password stash file for an existing PKCS#12 keystore.
      - The onkstore Utility
      - The onlog utility
        The onlog utility displays the contents of a logical-log file, either on disk or on backup.
      - The onmode utility
        Use the onmode utility to change the database server operating mode and perform various other operations on shared memory, sessions, transactions, parameters, and segments.
      - The onparams Utility
        Use the onparams utility to add or drop a logical-log file, change physical-log parameters, and add a new buffer pool.
      - The onpassword utility
        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.
      - The ifxclone utility
        You use the ifxclone utility to create a server clone from a snapshot of an existing database server.
      - The onspaces utility
        Use the onspaces utility to manage the storage spaces in your database.
      - The onstat utility
        The onstat utility reads shared-memory structures and provides statistics about the database server at the time that the command runs.

  - InformixHQ Guide
    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.
- Backup and Restore Guide
  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.
- Enterprise Replication
  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.

The onkstash Utility

Use the onkstash utility to create a password stash file for an existing PKCS#12 keystore.

A password stash file allows database clients or the database server itself access to their respective keystore without the inconvenience for the user to supply the password every time.

The onkstash utility accepts the file name of a PKCS#12 keystore (ending with extension ".p12") and the password for this keystore. It writes the password in an encrypted format to the password stash file. The name of this stash file is same as the keystore filename, but with the extension ".stl".

If the password for a keystore gets changed, the new password must be stashed again using the onkstash utility. If a password stash file exist with the old keystore password, then it is overwritten with the new password in an encrypted format.

Syntax

onkstash <keystore file> <password>

where <keystore file> is the name of the PKCS#12 keystore file, and <password> is the current password for the keystore.

Usage

The onkstash utility determines the file name for the password stash file from the name of the keystore file. It checks if the given password is correct and then writes it in an encrypted format to the stash file.

If the password stash file gets created by onkstash, the file access permissions are set to 600. If the password stash file already exists, the permissions are not changed. It is recommended to check the permissions for the keystore file as well as for the password stash file, and correct them if deemed necessary.

In addition to stashing the keystore password, the onkstash utility can also provide the version of the encryption library used. Run the command "onkstash -version" to determine, whether GSKit or OpenSSL is used as encryption library and the version of that library.
