The Amazon Machine Image (AMI) for HCL OneDB provides all the information required to launch a virtual server instance in the AWS cloud. Simply select the AMI that meets your business needs and launch as many instances as required. HCL OneDB AMI includes the latest versions of:

HCL OneDB Products

Installation directory

HCL OneDB Server


HCL OneDB Mongo(WireListener)




HCL OneDB Explore







Note: HCL OneDB server, CSDK, JDBC, WireListener, REST and HCL OneDB Explore are installed and configured for OLTP environments. Please contact Lab Services using the “Contact Us” panel for guidance and support.

HCL OneDB on AWS is an enterprise-class database offered on the Amazon Web Services (AWS) Cloud. It features a cloud-delivered, ready-to-run, fast, resilient, and scalable database management system that manages traditional relational, object-relational, and dimensional data types. HCL OneDB on AWS offers the complete features of HCL OneDB on-premises deployments without the complexity and risk of managing your own infrastructure. AWS provides an infrastructure to run HCL OneDB in a flexible, scalable, and cost-effective manner in the cloud

HCL OneDB is offered as an hourly Amazon Machine Image (AMI). An AMI is an image applied to compute and memory resources which Amazon calls “EC2”. To place an order in your AWS account, navigate to “Services”, and then “EC2”. Click the “Launch Instance” button.

  1. 1. Navigate to “AWS Marketplace.
  2. 2. Search for “HCL OneDB” and select the latest available version. (Delivery Method is AMI - Amazon Machine Image).
  3. 3. Click on the Continue to Subscribe button and complete all selections.
  4. 4. Proceed through the remaining steps to provision a HCL OneDB EC2 instance (virtual machine) on AWS.
  5. 5. Connect to the virtual machine via a ssh program, using the private key for the keypair specified during your instance provisioning.
    • SSH as the user “ubuntu”.
      Here’s an example:
    • $ ssh -i ~/.ssh/my_aws_private_key ubuntu@hostname-of-my-HCL onedb-ec2
  6. 6. After you are logged into the virtual machine, use the sudo command to become the user “Informix”.
    • Example: $ sudo -u informix bash

As the user Informix, you will be able to run the various HCL OneDB commands, such as onstat, onmode, and oninit. The machine is configured with the HCL OneDB server running and listening to the following client types on the respective ports:


Without TLS

With TLS

Installation directory

HCL OneDB Server (SQLI)




HCL OneDB Mongo(WireListener)








HCL OneDB Explore Server





To control the network traffic on the EC2 instance (to and from), it is preferable to use the Amazon “Security Group”, instead of an OS-based firewall configuration.

For security reasons, the OS (Operating Systems) accounts on the AMI do not have a password, and the only account initially configured for inbound SSH is “ubuntu”. To allow a remote client to connect to the HCL OneDB database server you can set a password on the desired OS account or create a database user via the CREATE USER STATEMENT.

HCL OneDB AMI can be ordered in all AWS regions and on all EC2 types. Since EC2 types have varying amounts of CPU and memory, several types and amounts of storage may be added to an EC2, tuning the HCL OneDB Server to meet your needs (E.g., altering the number of CPU VPs, increasing the size of the buffer-pool, adding dbspaces on the desired storage devices).

To connect a remote client to HCL OneDB, first ensure the AWS Security Group permits traffic on the appropriate ports. To encrypt communication between the client and server, configure the client for TLS by following these guidelines:

HCL OneDB certificate is located at /home/Informix/client_ssl/selfsigned_ssl.cert. For security reasons this certificate should be changed immediately to a certificate you control.

HCL OneDBExplore is a web-based monitoring and administration tool for DBAs and developers which by default will already be configured, up and running. The Explore Server and Agent processes run as the OS user "HCL onedbexpu".

  • From inside your provisioned instance, open a browser and connect to Explore.
  • If you prefer to access HCL OneDB Explore from a remote host, first ensure that the AWS Security Group permits the traffic, and then use a browser to connect to https:// (your EC2 instance IP address) :28002.
  • Details about the initial credentials can be found in the /opt/hcl/onedb/explore/explore/ file. This is a text file and can be viewed using the UNIX “cat” command. Please refer to: Starting HCL OneDB Explore Server
  • To change the password for the “Explore server admin”, log into Explore as user “admin” and then navigate to the “User Settings” area.

    Please refer to: HCL OneDB Explore Server – User Settings

HCL OneDB is initially configured to interact with clients using the SQLI, Mongo, and REST protocols and to run with a small buffer pool on a single CPU VP. If you have ordered a larger EC2 type and want to get more power from HCL OneDB please consider increasing the number of CPU VPs as well as the buffer pool.
