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.

Deploy Oracle E-Business Suite on Oracle Database@AWS

Summary (catalog)

EBS application tier on AWS EC2 with database on ExaCS via Database@AWS. App-to-DB connectivity through VPC-ODB peering. AWS ALB for web tier high availability.

Architecture (fetched from source)

Architecture

This architecture adheres to AWS landing zone best practices, employing multiple VPCs to logically separate shared and workload resources.

It establishes a highly scalable network topology by using AWS transit gateways, simplifying the deployment of complex hub-and-spoke networks. This robust network infrastructure facilitates seamless routing across AWS regions, between virtual networks, and to on-premises locations by using Direct Connect, Point-to-Site, and Site-to-Site VPN, all secured by AWS.

The following diagram shows the architecture for deploying Oracle E-Business Suite on Oracle Database@AWS .

Description of the illustration ebs-db-aws-architecture.png

ebs-db-aws-architecture-oracle.zip

The architecture has the following Oracle components:

  • OCI region An OCI region is a localized geographic area that contains one or more data centers, hosting availability domains. Regions are independent of other regions, and vast distances can separate them (across countries or even continents).

  • Availability domain Availability domains are standalone, independent data centers within a region. The physical resources in each availability domain are isolated from the resources in the other availability domains, which provides fault tolerance. Availability domains don’t share infrastructure such as power or cooling, or the internal availability domain network. So, a failure at one availability domain shouldn't affect the other availability domains in the region.

  • Virtual cloud network (VCN) and subnets A virtual cloud network (VCN) is a customizable, software-defined network that you set up in an OCI region. Like traditional data center networks, VCNs give you control over your network environment. A VCN can have multiple non-overlapping classless inter-domain routing (CIDR) blocks that you can change after you create the VCN. You can segment a VCN into subnets, which can be scoped to a region or to an availability domain. Each subnet consists of a contiguous range of addresses that don't overlap with the other subnets in the VCN. You can change the size of a subnet after creation. A subnet can be public or private.

In AWS, a VPC is the functional equivalent of a VCN.

  • Network security group (NSG) NSGs act as virtual firewalls for your cloud resources. With the zero-trust security model of OCI you control the network traffic inside a VCN. An NSG consists of a set of ingress and egress security rules that apply to only a specified set of virtual network interface cards (VNICs) in a single VCN.

  • Oracle Database@AWS Oracle Database@AWS is an Oracle Database cloud service on Oracle Cloud Infrastructure (OCI) that runs Oracle Database workloads in your Amazon Web Services (AWS) environment.

Oracle Database@AWS brings OCI technologies, such as Oracle Exadata Database Service , Oracle Autonomous Database , Oracle Real Application Clusters (Oracle RAC) and Oracle Data Guard to AWS customers.

  • Oracle Exadata Database Service on Dedicated Infrastructure Oracle Exadata Database Service on Dedicated Infrastructure enables you to leverage the power of Exadata in the cloud. Oracle Exadata Database Service delivers proven Oracle Database capabilities on purpose-built, optimized Oracle Exadata infrastructure in the public cloud. Built-in cloud automation, elastic resource scaling, security, and fast performance for all Oracle Database workloads helps you simplify management and reduce costs.

  • OCI Object Storage OCI Object Storage provides access to large amounts of structured and unstructured data of any content type, including database backups, analytic data, and rich content such as images and videos. You can safely and securely store data directly from applications or from within the cloud platform. You can scale storage without experiencing any degradation in performance or service reliability.

Use standard storage for "hot" storage that you need to access quickly, immediately, and frequently. Use archive storage for "cold" storage that you retain for long periods of time and seldom or rarely access.

This architecture has the following AWS components:

  • AWS availability zone An availability zone is a physically separate data center within a region designed to be available and fault-tolerant. Availability zones are close enough to have low-latency connections to other availability zones.

  • AWS Virtual Private Cloud An AWS Virtual Private Cloud (VPC) is a logically isolated section of the AWS Cloud where you can launch AWS resources, like EC2 instances, in a virtual network that you define. It provides a way to create your own private network within the AWS cloud, giving you control over your network configuration, including IP address range, subnets, route tables, and security groups.

  • Amazon FSx for NetApp ONTAP

Amazon FSx for NetApp ONTAP is a fully managed service that provides highly reliable, scalable, high-performing, and feature-rich file storage built on NetApp's popular ONTAP file system. FSx for ONTAP combines the familiar features, performance, capabilities, and API operations of NetApp file systems with the agility, scalability, and simplicity of a fully managed AWS service.

It offers scalability, efficiency, and security for enterprise workloads, including databases, virtualization, and AI applications. NetApp integrates with major cloud providers like AWS, and Google Cloud to enable seamless hybrid and multi-cloud deployments. With features like snapshots, deduplication, and disaster recovery, NetApp helps businesses optimize storage and data protection strategies. For this design we are using it for the Oracle EBS applications’ servers and for better security between production and non-production for cloning using Snap Mirror.

AWS FSx for NetApp ONTAP is used for Oracle E-Business Suite shared application tier file system (shared APPL_TOP) and as backup storage for Oracle databases using RMAN.

  • AWS Transit Gateway AWS Transit Gateway is a network transit hub used to interconnect virtual private clouds (VPCs) and on-premises/other networks. In the case of Oracle DB@AWS that is the ODB Network. As your cloud infrastructure expands globally, inter-region peering connects transit gateways together using the AWS Global Infrastructure. All network traffic between AWS data centers is automatically encrypted at the physical layer

  • AWS Direct Connect AWS Direct Connect provides a dedicated network connection between an on-premises network and the AWS Cloud, bypassing the public internet. This private connection offers increased bandwidth, reduced network costs, and a more consistent network experience compared to internet-based connections

  • Secure File Transfer Protocol Secure File Transfer Protocol (SFTP) is a network protocol that enables secure file transfer over SSH (Secure Shell), ensuring encryption and data integrity. Unlike traditional FTP, SFTP protects data during transmission by encrypting both commands and files, preventing unauthorized access. It supports authentication methods such as passwords, SSH keys, and multifactor authentication for enhanced security. SFTP is widely used for secure file sharing in enterprises, cloud environments, and automated data transfers.

  • Account

An AWS account is a fundamental resource container within Amazon Web Services (AWS) that holds your AWS resources and configurations. It's the primary way you interact with AWS services, providing a secure boundary for your cloud environment. Essentially, it's where you create, manage, and pay for your cloud-based resources.
