## What it does

The skill equips an agent with Node.js scripts targeted at Oracle database administration. It includes `execute_sql` for arbitrary statements alongside `get_query_plan`, which extracts execution metrics via `EXPLAIN PLAN` without running the query.

Diagnostics include `list_active_sessions` to display the default top 50 active connections with their SQL text. It also ships `list_top_sql_by_resource` to pinpoint the top 5 statements by CPU, I/O, or Elapsed Time. Storage tracking relies on `list_tablespace_usage` and schema checks through `list_invalid_objects`.

All scripts require Node.js. Database credentials must live in your `.env` files, as the scripts automatically read them; missing environment variables will cause executions to fail immediately.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill oracledb -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill oracledb -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill oracledb -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install cline/skills oracledb
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill oracledb -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/cline/skills --path skills/oracledb
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill oracledb -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/cline/skills/tree/HEAD/skills/oracledb/SKILL.md

## When to use it
- inspect execution plans using EXPLAIN PLAN without running SQL
- find invalid database objects requiring recompilation
- track tablespace utilization and storage space
- identify resource-heavy SQL statements by CPU or I/O

## Example prompts
- Check for invalid objects across the schema using list_invalid_objects.
- Generate an execution plan for SELECT * FROM orders WHERE id = 10
- List the top 5 SQL statements consuming the most CPU time.

BEGIN THIRD-PARTY FILE 22882ab6a668326a
```text

name: oracledb
description: Use these skills to manage and monitor Oracle databases by executing SQL statements, exploring schema metadata, analyzing query performance, monitoring active sessions and resource consumption, and managing storage and object health.
---

## Usage

All scripts can be executed using Node.js. Replace `<param_name>` and `<param_value>` with actual values.

**Bash:**
`node <skill_dir>/scripts/<script_name>.js '{"<param_name>": "<param_value>"}'`

**PowerShell:**
`node <skill_dir>/scripts/<script_name>.js '{\"<param_name>\": \"<param_value>\"}'`

Note: The scripts automatically load the environment variables from various .env files. Do not ask the user to set vars unless skill executions fails due to env var absence.


## Scripts


### execute_sql

Executes any SQL statement.

#### Parameters

| Name | Type | Description | Required | Default |
| :--- | :--- | :--- | :--- | :--- |
| sql | string | The SQL to execute. | Yes |  |


---

### get_query_plan

Generate a full execution plan for a single SQL statement using EXPLAIN PLAN. This can be used to analyze query performance without execution. Requires the SQL statement as input as a parameter.

#### Parameters

| Name | Type | Description | Required | Default |
| :--- | :--- | :--- | :--- | :--- |
| query | string | The SQL statement for which you want to generate plan (omit the EXPLAIN keyword). | Yes |  |


---

### list_active_sessions

List the top N (default 50) currently running database sessions (STATUS='ACTIVE'), showing SID, OS User, Program, and the current SQL statement text.



---

### list_invalid_objects

Lists all database objects that are in an invalid state, requiring recompilation (e.g., procedures, functions, views).



---

### list_tables

Lists all user tables in the connected schema, including segment size, row count, and last analyzed date. Filters by a comma-separated list of names. If names are omitted, lists all tables in the current user's schema.



---

### list_tablespace_usage

List tablespace names, total size, free space, and used percentage to monitor storage utilization.



---

### list_top_sql_by_resource

List the top N (default 5) SQL statements from the library cache based on a chosen resource metric (CPU, I/O, or Elapsed Time). Shows SQL ID, execution count, buffer gets, disk reads, CPU time, and elapsed time.
