We recently announced the availability of AD-TXK Delta 13. This is part three in a series of blog articles to highlight the Oracle E-Business Suite (EBS) System Schema Migration, a key new feature of AD-TXK Delta 13 and Oracle E-Business Suite Release 12.2.11.

What are the Requirements to Complete the EBS System Schema Migration?

There are four requirements to complete the EBS System Schema Migration as follows:

  1. Apply AD-TXK Delta 13.
  2. Apply the EBS 12.2.11 Release Update Patch (RUP) or the EBS System Schema Migration Consolidated Patch.
  3. Update Your Custom Code with Mandatory Compliance Requirements.
  4. Apply the EBS System Schema Migration Completion Patch.

For more information, see the following:  Oracle E-Business Suite Release 12.2 System Schema Migration (MOS Note 2755875.1)

This blog article focuses on Requirement 1: Apply AD-TXK Delta 13. The remaining requirements to complete the EBS System Schema Migration will be described in detail in upcoming blog articles.

What are the Key Features of AD-TXK Delta 13?

The following are the key features introduced with AD-TXK Delta 13:

  • A new schema, EBS_SYSTEM, is created. Prior to the introduction of the EBS_SYSTEM schema, Oracle E-Business Suite installed application objects in the Oracle Database SYS and SYSTEM schemas. Migration to the EBS_SYSTEM schema removes the need for any EBS-owned objects to reside in the SYS and SYSTEM schemas.  
  • All EBS administration utilities (such as adop, adadmin) now prompt for the EBS_SYSTEM password.
  • AD and TXK code objects are moved from the SYS or SYSTEM schemas to EBS schemas (APPS, APPS_NE or EBS_SYSTEM) and all EBS code references to the moved code objects are updated accordingly.  
  • AD and TXK code has been updated to leverage public database APIs.
  • Database service names are now used for EBS application tier connections to the database.

How Do You Apply AD-TXK Delta 13?

Applying AD-TXK Delta 13 is similar to other AD and TXK RUPs. Use the instructions in the following My Oracle Support knowledge document to apply AD-TXK Delta 13:

Per the documentation, perform the following tasks prior to applying AD-TXK Delta 13:

  • Run the Online Patching Database Compliance Checker (ADZDDBCC.sql) to verify the health of your EBS database objects and configuration.
  • Download the patches and manually run adgrants.sql on the database tier which will:
    • Create the EBS_SYSTEM schema.
    • Grant the required privileges to the EBS_SYSTEM schema.
  • Manually unlock the EBS_SYSTEM account.
  • Manually set the EBS_SYSTEM password to match the SYSTEM password.
