root b30a4f0d32 Diagram generation: ref-arch-driven procedure + spec validator + KB enrichment 
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.

Provision and deploy a maximum availability solution for PeopleSoft on Oracle Cloud

Summary (catalog)

Step-by-step PeopleSoft MAA deployment on OCI. Terraform stacks for infrastructure provisioning, Data Guard configuration, and PeopleSoft application tier setup.

Architecture (fetched from source)

Architecture

This architecture shows an Oracle Maximum Availability Architecture (Oracle MAA) solution for PeopleSoft. The PeopleSoft high availability architecture is layered on top of Oracle Database and Oracle Fusion Middleware maximum availability architectures, including a secondary site to provide business continuity in the event of a primary site failure.

The following shows a full-stack Oracle MAA architecture, including primary and secondary sites. The secondary site is a replica of the primary.

Description of the illustration peoplesoft-maa-arch.png

peoplesoft-maa-arch-oracle.zip

Each site consists of the following:

  • An HTTPS load balancer for web-based application services

  • Two servers that host the PeopleSoft Pure Internet Architecture (PIA) domain

  • Two servers that host both the PeopleSoft Application Server and the Process Scheduler domains

  • A shared file system for PeopleSoft application software and report repository

  • An Oracle Real Application Clusters (Oracle RAC) database, with two database servers and shared storage

  • Oracle Active Data Guard , which allows routing of “mostly read operations” to the standby database while keeping the standby database current with the primary

Both the application tier shared file system and the database are replicated to the secondary site – the application tier using rsync, and the database tier using Oracle Data Guard .

The data at the second site is kept in sync with the primary by using appropriate replication mechanisms.

  • For the database itself, Oracle Active Data Guard ensures the standby database is kept in sync and transactionally consistent.

  • For file system output generated during the operation of the application, rsync is used to frequently replicate the output to another region. There will be a small gap to resolve by identifying missing file system components and determining the action to take for each.

About Required Services and Roles

This solution requires the following services and roles:

  • Oracle Cloud Infrastructure (OCI)

  • PeopleSoft

  • Oracle Exadata Database Service on Dedicated Infrastructure

These are the roles needed for each service.

  • Define network topology

  • Provision Virtual Cloud Networks (VCNs)

  • Provision network resources such as route tables, gateways and subnets

  • Establish network firewalls rules by creating security lists and applying them to the appropriate subnet.

  • Provision and manage OCI load balancer (LBaaS)

  • Obtain signed TLS/SSL certificates for LBaaS

Oracle Cloud Infrastructure Oracle Exadata Database Service on Dedicated Infrastructure : Tenancy Administrator / PeopleSoft administrator

  • Provision Oracle Exadata Database Service on Dedicated Infrastructure , compute instances and OCI File Storage resources

Compute Instances VM OS: psadm2 Install, configure and manage PeopleSoft application tier components

PeopleSoft Application Administrator: ps Configure roles and responsibilities, UI configuration, Process scheduler setup, and so on within the application

Note:

There are other users and passwords that are specific to the PeopleSoft deployment. For example, Tuxedo and Oracle WebLogic Server domains, that are only known to the implementation team and are not covered here.
