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

2012-08-31 17:02 435 查看

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.

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.

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.

Shut down the application tier services

For 10gR2 and 11gR1, de-register the original database server machine

Export OLAP analytical workspaces

Create a .trc file to use as template to recreate the control files on the target machine

Shut down the original (source) database

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.

Prepare the source system

Prepare the source system application tier for cloning

Copy the source system to the target system

Copy the application tier file system

Update the Target System

Update environment variable

On the target system, set the environment variable LDEMULATION to elf_i386.

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.

Natively recompile PL/SQL code

Start the new database listener

For 11gR2, de-register the original database server machine

Implement and run AutoConfig on the database server node

Re-create custom database links

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.

Relink AD executables (Use AD Relink for this step)

Relink Applications programs

Generate message files

Generate form files

Generate report files

Generate product JAR files

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

Update profile options

Update printer settings

Update Workflow configuration settings

Verify APPLCSF variable setting

Update the SESSION_COOKIE_DOMAIN value in ICX_PARAMETERS
