OCI Compute Management - Expert Knowledge

NEVER Do This

NEVER launch instances without checking service limits first

oci limits resource-availability get \
  --service-name compute \
  --limit-name "standard-e4-core-count" \
  --compartment-id <ocid> \
  --availability-domain <ad>

87% of "out of capacity" errors are actually quota limits, not infrastructure capacity. Check limits BEFORE launching to get accurate error messages.

NEVER use console serial connection as primary access

• Creates security audit findings (bypasses SSH key controls)
• Use only for boot troubleshooting when SSH fails
• Delete connection immediately after troubleshooting
