## What it does

This skill investigates network, authentication and driver failures around Amazon RDS for Oracle. It covers port `1521`, VPC peering, Transit Gateway, `ORA-12170`, thin and thick `python-oracledb` modes, and `DPI-1047` Oracle Client errors.

It includes patterns for EC2, ECS Fargate, EKS and Lambda, with Secrets Manager, Kerberos, TLS/TCPS, NNE, SSM port forwarding and Oracle Connection Manager on EC2. RDS Proxy does not support RDS Oracle, so you need a different connection-pooling route.

The skill asks for explicit confirmation before creating or changing RDS resources. It will not delete an instance, force a failover, reboot it or enable public access; it offers an assessment instead.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill rds-oracle -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/rds-oracle/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/rds-oracle/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill rds-oracle -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/rds-oracle/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill rds-oracle -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/rds-oracle/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aws/agent-toolkit-for-aws rds-oracle
```

2. **Manually: put the files in place**
- File: `.github/skills/rds-oracle/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill rds-oracle -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aws/agent-toolkit-for-aws --path skills/specialized-skills/database-skills/rds-oracle
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/rds-oracle/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill rds-oracle -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aws/agent-toolkit-for-aws/tree/HEAD/skills/specialized-skills/database-skills/rds-oracle/SKILL.md

## When to use it
- trace `ORA-12170` timeouts across VPCs
- fix `DPI-1047` in `python-oracledb`
- plan a Lambda connection to RDS Oracle
- connect EKS workloads through stored Oracle secrets
- check TLS/TCPS or NNE transport encryption

## Example prompts
- “Investigate an `ORA-12170` timeout from EC2 to RDS Oracle in another VPC.”
- “Help me fix `DPI-1047` in a `python-oracledb` application.”
- “Review a Lambda connection design for RDS Oracle using Secrets Manager.”

# Amazon RDS for Oracle — Connectivity

## Safety guidance

This skill covers creating and modifying RDS for Oracle resources when the user requests it. The agent MUST confirm the action with the user before executing. Do NOT execute any create or modify operation without explicit user confirmation (e.g., "yes", "proceed", "confirmed", "go ahead"). If the user has not confirmed, present the planned action and ask for approval.

### Execute these operations (after user confirmation)

- Create an instance: `create-db-instance` (requires a DB subnet group; RDS Oracle is VPC-only and not publicly accessible by default)
- Create a custom parameter group: `create-db-parameter-group` (family `oracle-se2-19`, `oracle-ee-19`, etc.)
- Create an option group: `create-option-group` (for Oracle Native Network Encryption, TLS/TCPS, S3 integration, APEX, Spatial)
- Change backup retention: `modify-db-instance --backup-retention-period`
- Enable/disable deletion protection: `modify-db-instance --deletion-protection`
- Change CloudWatch log exports: `modify-db-instance --cloudwatch-logs-export-configuration`
- Attach/detach parameter group or option group: `modify-db-instance --db-parameter-group-name / --option-group-name`
- Tag resources: `add-tags-to-resource`, `remove-tags-from-resource`

### Resource tagging (always apply on resource creation)

When creating any RDS for Oracle resource (`create-db-instance`, `create-db-parameter-group`, `create-option-group`, `create-db-instance-read-replica`), ALWAYS include these tags using the RDS list-of-records `--tags` syntax:

`--tags Key=created_by,Value=rds-oracle-skill Key=generation_model,Value={your-model-id}`

Example: `--tags Key=created_by,Value=rds-oracle-skill Key=generation_model,Value=claude-sonnet-4-20250514`

Include these tags even if the user does not mention tagging, so that they can identify the resources created via this skill. If the user provides additional tags, append these to their tags rather than replacing them. The same applies when tagging via `add-tags-to-resource` on existing resources.
```
