This topic outlines the prerequisites for provisioning a virtual EBS R12.2 instance to target environments.

 

Ensure your target EBS R12.2 instance is supported

See Virtual EBS R12.2 Instance Requirements to ensure you can provision your EBS R12.2 instance.

Ensure your EBS 12.2 environments comply with Oracle's documentation

Your environments must comply with Oracle's requirements for installing EBS. These requirements are outlined on Oracle E-Business Suite Release Notes, Release 12.2 (Doc ID 1320300.1) found at https://support.oracle.com.

Oracle has released an E-Business Suite Pre-Install RPM (available on ULN and public yum) that includes all required RPMs for both the appsTier and dbTier of a R12.2 installation. Details can be found in Oracle E-Business Suite Installation and Upgrade Notes Release 12 (12.2) for Linux x86-64 (Doc ID 1330701.1) found at https://support.oracle.com.

Prepare the dbTier for provisioning

Delphix Engine's Unix Environment Requirements

The dbTier must meet the target requirements outlined in Requirements for Unix Environments. These requirements are generic to all target Unix environments you add to the Delphix Engine.

oracle User

The Delphix Engine must have access to an oracle user on the dbTier.

  • This user should be a member of both the EBS dba and oinstall groups.
  • This user will be given proper permissions to manage the dbTechStack and database.

oraInst.loc

An oraInst.loc file must exist on the dbTier prior to provisioning. This file will specify where the oraInventory directories live or where they should be created if they do not already exist.

The oraInst.loc file is typically located at /etc/oraInst.loc on Linux or /var/opt/oracle/oraInst.loc on Solaris. Ensure that the oraInventory to which this file points is writeable by the oracle user.

Consult Oracle EBS documentation for more information about where to place this file on your dbTier and what this file should contain.

Oracle Central Inventory

The Oracle Central Inventory is a repository for all Oracle products (software) installed on a system. Since the Central Inventory consists of system-specific information, it is required that the Central Inventory be saved on a local non-shared directory on the system. While software can be shared across nodes, the inventory should be local to each system. The global inventory/central inventory(oraInventory) for each node should be on a local file system other than Delphix mount base path.

The Delphix Engine's Oracle Database Requirements

The dbTier must meet the target requirements outlined in Oracle Support and Requirements. These requirements are generic to all target Unix environments expected to host a virtual Oracle database.

Prepare the appsTier for Provisioning

Delphix Engine's Unix Environment Requirements

The appsTier must meet the target requirements outlined in Requirements for Unix Environments. These requirements are generic to all target Unix environments added to the Delphix Engine.

applmgr User

The Delphix Engine must have access to an applmgr user on the appsTier.

  • This user should be a member of the EBS oinstall group.
  • This user will be given proper permissions to manage the appsTier.  

oraInst.loc

An oraInst.loc file must exist on every appsTier node prior to provisioning. This file will specify where the oraInventory directories live or where they should be created if they do not already exist.

The oraInst.loc file is typically located at /etc/oraInst.loc on Linux or /var/opt/oracle/oraInst.loc on Solaris. Ensure that the oraInventory to which this file points is writable by the applmgr user or application tier OS user.

If you are provisioning a single-node appsTier,

    • [Required] The global inventory/central inventory(oraInventory) for each node should be on a local file system other than Delphix mount base path.

If you are provisioning a multi-node appsTier,

    • The following recommendations are mandatory;
      • While configuring SHARED APPL_TOP application, Delphix expects the oraInventory directory path should be beneath the Delphix mount base path.
      • The inventory_loc variable defined in file /etc/oraInst.loc on all application servers should point to same shared oraInventory directory location on shared Delphix mount base path.
      • The Delphix Engine's cloning workflow requires that all nodes in the appsTier have access to the shared oraInventory directories via Delphix-provided storage.
    • [Required] The Delphix Engine's automation requires that all nodes in the appsTier have access to the oraInventory directories via Delphix-provided storage.

Objective of placing oraInventory on Shared Delphix mount storage

While configuring shared APPL_TOP application, instead of storing oraInventory on the local directory of each server, all application servers should  point to the same oraInventory directory on shared Delphix mount storage, so that you need to patch only on a single server and the oralnventory gets in-sync for all application servers thus preventing the oralnventory of remaining servers becoming invalid.

Details can be found in Sharing The Application Tier File System in Oracle E-Business Suite Release 12 (Doc ID 384248.1) found at https://support.oracle.com. You can also consult Oracle EBS documentation for more information about where to place this file on your appsTier and what this file should contain.
