Oracle EBS R12 shared file system using oracle cloud FSS

Creating a shared file system for Oracle E-Business Suite (EBS) R12 using Oracle Cloud File Storage Service (FSS) involves several steps. Oracle Cloud FSS provides a scalable and secure NFS-based file storage solution, which can be used for shared file systems in Oracle EBS R12 environments. Here's a high-level guide on setting up this configuration:

Prerequisites

1. Oracle Cloud Infrastructure (OCI) Account: Ensure you have an active OCI account with necessary permissions.
2. Oracle EBS R12 Environment: An existing or New Oracle EBS R12 environment setup in OCI or Clone
3. OCI CLI or Console Access: You can use either the OCI CLI or the web console to configure FSS.

Steps to Configure Shared File System Using Oracle Cloud FSS

Create File System

• OCI Console > Storage > File Storage > Create File System
• Name: EBS_Shared_FS
• Compartment: your_compartment

Create Mount Target

• OCI Console > Storage > File Storage > Mount Targets > Create Mount Target
• Name: "EBS_Mount_Target"
• Compartment: "your_compartment"
• VCN: "your_vcn"
• Subnet: "your_subnet"

Configure Export Options

• OCI Console > Storage > File Storage > File Systems > EBS_Shared_FS > Export Options > Create ExportExport
• Path: /ebs_shared
• Source: 0.0.0.0/0 (or restrict to specific IPs/Subnets)
• Access: Read/Write

Mount File System on EBS Nodes

• On each EBS node
• sudo yum install -y nfs-utils
• sudo mkdir -p /mnt/ebs_shared
• sudo mount <mount_target_ip>:/ebs_shared /mnt/ebs_shared
• echo "<mount_target_ip>:/ebs_shared /mnt/ebs_shared nfs defaults 0 0" | sudo tee -a /etc/fstab

1. Configure Oracle EBS to Use the Shared File System:

• Modify the Oracle EBS configuration to use the new shared file system.
• Update the Utl_file_dir parameter in the database if necessary.
• Configure application and concurrent manager nodes to use the shared storage for necessary directories such as $APPLCSF, $COMMON_TOP, $APPL_TOP, etc.
