# Use SQL*Plus to Validate RDS Database Connectivity **Last reviewed:** September 22, 2026 Use this page when SQL\*Plus is needed to validate Oracle-compatible RDS connectivity or run approved diagnostic queries for AIQ-related environments. ## Recommended guidance - Confirm the database engine is Oracle-compatible before using SQL\*Plus. - Use approved client software and least-privilege database accounts. - Never paste database passwords or connection strings with secrets into documentation. ## Validation workflow 1. Confirm hostname, port, service name/SID, network access, and security group rules. 2. Install the approved Oracle client or SQL\*Plus package for the admin workstation or host. 3. Test connectivity with a least-privilege account. 4. Run only approved read-only diagnostic queries unless a change window authorizes updates. 5. Record results without including credentials. **Note:** This article is not MySQL-specific despite its current book location; consider moving or consolidating if database books are reorganized. --- Last updated: September 22, 2026 If you have feedback on this topic, contact .
