1 Understanding the Oracle Fusion Middleware 11g Release 1 (11.1.1.1.0) Migration

This chapter contains the following sections:

1.1 What is a Patch Set?

Patch set is a mechanism for delivering fully tested and integrated product fixes. A patch set includes all files that have been rebuilt to implement the bug fixes. All of the fixes in the patch set have been tested and are certified to work with one another.

Oracle Fusion Middleware 11g Release 1 (11.1.1.2.0) is cumulative and includes all of the fixes from Oracle Fusion Middleware 11g Release 1 (11.1.1.1.0).

Patch sets contain generic fixes that apply to all platforms and may also include platform-specific fixes.

1.2 Overview of Oracle Fusion Middleware 11g Release 1 (11.1.1.2.0) Patch Assistant

Patch Assistant enables you to migrate your existing configuration of Oracle Fusion Middleware 11g Release 1 (11.1.1.1.0) components, used in conjunction with the 11.1.1.1.0 and 11.1.1.2.0 installations. Patch Assistant is not a complete software distribution. You must run this Patch Assistant over an existing Oracle Fusion Middleware 11g Release 1 (11.1.1.1.0) installation. Patch Assistant is designed to work with all Oracle Fusion Middleware 11g Release 1 (11.1.1.1.0) products. You may see messages that an Oracle product is not present in a domain or instance. This message is informational and does not indicate an error.

Refer to Table 3-7 for the Oracle Fusion Middleware components supported by Patch Assistant.

Note:

Patch Assistant is used only for updating Oracle Fusion Middleware 11g Release 1 (11.1.1.1.0) Domains and Oracle Instances. If you are not updating your existing 11.1.1.1.0 domains and instances, you are not required to use Patch Assistant.

Patch Assistant helps to migrate the following from Oracle Fusion Middleware 11g Release 1 (11.1.1.1.0):

  • Oracle Fusion Middleware Domains

    Note:

    It is required that you migrate the entire Oracle WebLogic domain. When the domain is migrated, all components in the domain are also migrated.
  • Oracle Instances

  • Oracle Fusion Middleware 11g Release 1 (11.1.1.1.0) database schema created using Oracle Repository Creation Utility (RCU)

    Note:

    You must migrate both the schema and the middle tier.

When you run Patch Assistant tool, the configuration files contained in the Oracle Fusion Middleware 11g Release 1 (11.1.1.1.0) domain and Instance directories are copied to the new directories in the Oracle Fusion Middleware 11g Release 1 (11.1.1.2.0) installation. The Middleware home is the full path of the Oracle directory that contains the Oracle Fusion Middleware installation, and MW_HOME will be used in this documentation to refer to the directory where the product is installed.

Note:

MW_HOME must be replaced with the full path name of the installed Oracle Fusion Middleware instance.
