Oracle Database Client 21c - Multi-OS,

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

## Oracle Database Client 21c AMI by cloudimg

Connect your application tiers, CI/CD pipelines, and DBA workstations to Oracle Database servers in minutes - not hours. This pre-configured AMI eliminates the manual download, dependency resolution, and environment variable setup that typically consumes 2-4 hours of engineering time per instance. Launch a production-ready Oracle Client environment with a single click and start querying immediately.

## Why This AMI Instead of a Manual Install

Installing Oracle Database Client on a vanilla EC2 instance requires downloading the installer from Oracle, resolving library dependencies for your specific Linux distribution, configuring ORACLE_HOME and PATH variables, setting up tnsnames.ora, and validating connectivity. This AMI delivers all of that pre-solved:

• Oracle Database Client 21c fully installed and configured with OCI, SQL*Plus, JDBC, and ODP.NET Core libraries
• Environment variables and paths pre-set so tools work immediately after launch
• AWS CLI v2, Systems Manager Agent, and CloudWatch Agent pre-installed for automation and observability
• ENA networking enabled for low-latency, high-throughput connections (up to 25 Gbps single flow)
• SELinux enabled with latest security patches applied at build time

## Supported Operating Systems

Choose the Linux distribution that matches your existing fleet standards - all from a single listing:

• Oracle Linux 8
• CentOS 7
• AlmaLinux 8
• Rocky Linux 9

This eliminates the need for separate subscriptions or custom builds when your organization runs mixed Linux environments.

## Common Use Cases

• Microservices and application tiers requiring OCI, JDBC, or ODP.NET Core libraries to connect to Oracle Database servers
• CI/CD pipelines running Data Pump exports, RMAN backups, or SQL*Plus automation scripts
• DBA workstations for ad-hoc queries, monitoring, and administrative tasks
• BI gateways and monitoring agents that need lightweight, secure Oracle connectivity on EC2

## Security Baseline

• Hardened OS image with SELinux enforcing mode enabled
• Latest patches applied at AMI build time
• No database engine or listener included - this is a client-only image with minimal attack surface
• Deploy in a private subnet with security groups restricting outbound traffic to port 1521 on your database hosts

## Requirements and Limitations

• Architecture: x86_64 (AMD/Intel) EC2 instances
• Minimum instance: t3.small (2 vCPU, 2 GB RAM) for light workloads; m5.large recommended for CI/CD pipelines
• Oracle licensing: This AMI contains the Oracle Database Client only. You must hold appropriate Oracle Database licenses or use Oracle Technology Network license terms for your database server connections.
• Supported server versions: Oracle Database Client 21c is certified to connect to Oracle Database12.1, 12.2, 19c, and 21c servers
• Not included: No database engine, no listener, no Oracle Enterprise Manager agent

## 24/7 Expert Support

This AMI includes round-the-clock support from cloudimg specialists with an average one-hour ticket response time and a guaranteed 24-hour resolution SLA. Whether you need help with tnsnames.ora configuration, connectivity troubleshooting, or integration with your CI/CD toolchain, our team is available 365 days a year.

## Get Started

Launch the AMI, SSH into your instance, and run "sqlplus username@service_name" to verify connectivity to your Oracle Database. Pre-configured environment variables mean no additional setup is required for basic operations.
