The diagram path now follows a documented standard procedure (lookup the closest Oracle Architecture Center reference → confirm components → author absolute_layout → spec validator → render → visually verify) and ships persistent guardrails so layout regressions can't recur. Persistent procedure changes (apply to all users, all sessions): - tools/diagram_spec_validator.py — geometry checks (CONTAINER_TOO_THIN, CONTAINER_PADDING_VIOLATION, LABEL_OVERFLOW_PARENT) run BEFORE either renderer (drawio + PPTX). Catches the subnet-collapse / label-overflow bugs that the post-render drawio validator missed. - tools/oci_diagram_gen.py + tools/oci_pptx_diagram_gen.py — call the spec validator before emitting any output. Adds mysql / mysql_heatwave type aliases. - tools/archcenter_pattern_lookup.py — scores against cached page descriptions (not just the 1-line summary), supports --queries for multi-fragment composition, and applies synonym expansion via kb/architecture-center/synonyms.yaml so "LB HA cross AD" matches "load balancer high availability availability domain". - kb/architecture-center/synonyms.yaml — canonical synonym table (load balancer, autonomous database, data guard, …) used by the lookup scorer. KB enrichment: - tools/archcenter_description_fetcher.py + 121 cached _description.md under kb/diagram/assets/archcenter-refs/<slug>/. Removes the runtime dependency on docs.oracle.com when authoring specs and feeds the pattern-lookup scorer. - 110+ cached .drawio / .svg / .png references for offline reuse, plus the OCI Toolkit v24.2 import (kb/diagram/assets/oci-toolkit-drawio). Documentation: - docs/skill/output-formats.md — new "Standard diagram-generation procedure (MANDATORY)" + geometry rules + the new validator entry. - SKILL.md option 2 — references the mandatory procedure. - README.md — describes the spec validator, archcenter_pattern_lookup and description fetcher, and updates the KB-health table. Tooling that backs the procedure (cumulative across recent sessions): tools/archcenter_case_runner.py, archcenter_batch_driver.py, archcenter_zip_downloader.py, drawio_visual_validator.py, drawio_fidelity_eval.py, harvest_drawio_icon.py, import_oci_library.py, oci_pptx_diagram_gen.py, oci_pptx_render.py, refresh_pptx_icon_index.py.

Considerations for Configuration
Before you begin to configure backups and recovery, review these assumptions and considerations.
-
The virtual cloud network (VCN) where Oracle Exadata Database Service on Dedicated Infrastructure is configured, must route packages to the OCI Services Network (where Recovery Service is configured) via a service gateway.
-
There are two types of backups: Oracle managed backups and user configured backups. Oracle managed backups are configured using the OCI console or REST API. User configured backups are configured using the dbaascli only.
-
This playbook uses Oracle managed backups to Recovery Service . User configured backups are out of scope of this playbook.
-
Combining Oracle managed backups and user configured backups is not supported.
-
The Recovery Service enables databases to restore to the last known good state with minimal data loss, to a specific timestamp, or SCN. The OCI console, however, does not support restoring a database from a specific backup from the list of backups displayed in the console. Although it's not possible to restore a database from a backup in this list, the list of backups can be used as a reference as to what data is currently available for restore operations.
-
The OCI console cannot restore a particular pluggable database (PDB) . Only the full container database (CDB) can be restored.
