Migrating Oracle E-Business Suite R12 from Linux 32-bit to Linux 64-bit [ID 471566.1]

Overview

This document details the process of migrating an Oracle E-Business Suite Release 12 system from a Linux 32-bit operating system to a Linux 64-bit operating system. The migration process incorporates portions of existing processes and references steps in existing documentation. The details of each step are not repeated in this document.

The successful completion of all relevant steps in the Installation and Upgrade Notes for both the source system (Linux 32-bit) and the target system (Linux 64-bit) is required before starting the migration process.

Prerequisites

Prior to performing the migration, both the source and target systems must meet the requirements documented in the Installation and Upgrade Notes (Linux 32-bit and Linux 64-bit, respectively) and Cloning Oracle Applications Release 12 with Rapid Clone.

    1. Perform all prerequisite steps in the Rapid Clone document

      Section 1: Prerequisite Tasks of the Cloning Oracle Applications Release 12 with Rapid Clone document details the prerequisite steps to clone an Oracle E-Business Suite system. The platform migration process in this document requires cloning the application tier components from the Linux 32-bit environment to the Linux 64-bit environment. Perform all steps in Section 1: Prerequisite Tasks to prepare both the source and target systems for the migration of the Oracle E-Business Suite system.

    2. Install the Database Oracle home

      On the target Linux 64-bit machine, perform the installation of the database that corresponds to the database version on the source system.

      10gR2
      For 12.0, install the 10.2.0 database Oracle home using 12.0 Rapid Install. See the "Installing Technology Stack Components" chapter of the Oracle Applications Installation Guide: Using Rapid Install (Release 12.0).

      11gR1
      For 12.0, see the "Before the Database Installation" and "Database Installation" sub-sections of Section 1 in the Interoperability Notes Oracle E-Business Suite Release 12.0 with Oracle Database 11g Release 1 (11.1.0.6) or Interoperability Notes Oracle E-Business Suite Release 12.0 with Oracle Database 11g Release 1 (11.1.0.7).

      For 12.1, install the 11.1.0 database Oracle home using 12.1 Rapid Install. See the "Installing Technology Stack Components" chapter of the Oracle E-Business Suite Installation Guide: Using Rapid Install (Release 12.1).

      11gR2
      For 12.0 and 12.1, see the "Before the Database Installation" and "Database Installation" sub-sections of Section 1 in the Interoperability Notes Oracle E-Business Suite Release 12 with Oracle Database 11g Release 2 (11.2.0).



Note: The source and target database versions must be the same. Be sure to include the Oracle OLAP option in the database installation on the target system.

Migration

The migration of the E-Business Suite system from the 32-bit environment to the 64-bit environment is a two-part process of migrating the application tier using the steps documented in Cloning Oracle Applications Release 12 with Rapid Clone and migrating the database using the steps documented in My Oracle Support Notes 456197.1 (10gR2), 762669.1 (11gR1), 456347.1 (11gR2).

Migrate the Database Tier

Refer to Section 3: Migration Procedure in the corresponding My Oracle Support Notes 456197.1 (10gR2), 762669.1 (11gR1), 456347.1(11gR2) and perform the following steps.

  1. Shut down the application tier services
  2. For 10gR2 and 11gR1, de-register the original database server machine
  3. Export OLAP analytical workspaces
  4. Create a .trc file to use as template to recreate the control files on the target machine
  5. Shut down the original (source) database
  6. For 10gR2, choose (Option A) Migrate Linux 32-bit database to Linux Itanium, which applies to database migrations from Linux 32-bit to Linux 64-bit; after (Option A) is completed, import OLAP analytical workspaces
    For 11gR1 and 11gR2, choose (Option B) Migrate Linux 32-bit database to Linux x86-64

Migrate the Application Tier

Refer to Section 2: Cloning Tasks of Cloning Oracle Applications Release 12 with Rapid Clone and perform the following steps.

  1. Prepare the source system
    • Prepare the source system application tier for cloning

  2. Copy the source system to the target system
    • Copy the application tier file system

Update the Target System

  1. Update environment variable
    On the target system, set the environment variable LDEMULATION to elf_i386.
  2. Update CTXORIG.xml
    Update the the value of the s_platform parameter in CTXORIG.xml from Linux to LINUX_X86-64. The CTXORIG.xml file is located in the <COMMON_TOP>/clone/context/apps directory of the target system. A sample entry is shown below:
    <platform oa_var="s_platform" osd="LINUX_X86-64">LINUX_X86-64</platform>

Post-Migration

The post-migration of the E-Business Suite system from the 32-bit environment to the 64-bit environment is a two-part process of setting up the application tier using the steps documented in Oracle E-Business Suite Maintenance Procedures and Cloning Oracle Applications Release 12 with Rapid Clone and configuring the target database using the steps documented in My Oracle Support Notes 456197.1 (10gR2), 762669.1 (11gR1), 456347.1 (11gR2).

Database Tier

Refer to Section 4: Post-Migration Tasks in the corresponding My Oracle Support Notes 456197.1 (10gR2), 762669.1 (11gR1), 456347.1(11gR2) and perform the following steps to configure the target system and to synchronize the application tier with the database tier.

  1. Natively recompile PL/SQL code
  2. Start the new database listener
  3. For 11gR2, de-register the original database server machine
  4. Implement and run AutoConfig on the database server node
  5. Re-create custom database links
  6. Reconfigure the application tier to connect to the target database machine

Application Tier

Refer to Section 2: Cloning Tasks of Cloning Oracle Applications Release 12 with Rapid Clone and perform the following steps.

  • Configure the target system
    • Configure the target system application tier server nodes

Refer to Oracle E-Business Suite Maintenance Procedures and perform the following steps using AD Administration.

  1. Relink AD executables (Use AD Relink for this step)
  2. Relink Applications programs
  3. Generate message files
  4. Generate form files
  5. Generate report files
  6. Generate product JAR files

Refer to Section 3: Finishing Tasks of Cloning Oracle Applications Release 12 with Rapid Clone and perform the following steps.

  1. Update profile options
  2. Update printer settings
  3. Update Workflow configuration settings
  4. Verify APPLCSF variable setting
  5. Update the SESSION_COOKIE_DOMAIN value in ICX_PARAMETERS
