---
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.

### list_invalid_objects

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



---

### list_tables

---

### list_top_sql_by_resource
