  1. Copy the service pack file to the <PRODUCT_HOME>/repository/components/servicepacks/ directory. For example, the image below shows how a new service pack named servicepack001 is added to this directory. 
    The servicepacks directory with the new servicepack001 subdirectory, which contains servicepack_patches.txt and the lib subdirectory with the patch JAR files.
  2. Start your product. The following steps will be executed:

    1. Before applying any patches, the process first creates a backup folder named patch0000 inside the <PRODUCT_HOME>/repository/components/patches/ directory, which will contain the original content of the <PRODUCT_HOME>/repository/components/plugins/ directory. This step enables you to revert back to the previous state if something goes wrong during operations.

    2. The latest service pack in the <PRODUCT_HOME>/repository/components/servicepacks/ directory will be applied. That is, the patches in the service pack will be applied to the <PRODUCT_HOME>/repository/components/plugins/ directory.

    3. In addition to the service pack, if there are individual patches added to the <PRODUCT_HOME>/repository/components/patches/ directory, those will also be incrementally applied to the plugins directory. 

      Info

      The metadata file available in the service pack will maintain a list of the applied patches by service pack. Therefore, the metadata file will be compared against the <PRODUCT_HOME>/repository/components/patches/ directory, and only the patches that were not applied by the service pack will be incrementally applied to the plugins directory. 

...

You can apply each patch individually to your system as explained below. Alternatively, you can apply patches through service packs as explained above.

  1. Copy the patches to the <PRODUCT_HOME>/repository/components/patches/ directory.

  2. Start the Carbon server. The patches will then be incrementally applied to the plugins directory.

    Note

    Before applying any patches, the process first creates a backup folder named patch0000 inside the <PRODUCT_HOME>/repository/components/patches/ directory, which will contain the original content of the <PRODUCT_HOME>/repository/components/plugins/ directory. This step enables you to revert back to the previous state if something goes wrong during operations.
