You can use the IBM® Installation Manager command
line to update the product with the fix packs that are available for WebSphere® Application Server Liberty
Core.
Before you begin
Important:
Java™ SE 17 is the recommended Java SDK because it provides the latest features and security updates. As an
alternative to installing Java SE 17, you can install another
supported Java SDK version. Liberty runs on any of the Java SE versions that
are listed in the Java SE versions column of the Supported Java Releases table on the Open Liberty website.
The Liberty end of support date for Java
SE 11 is October 2026, fix pack 26.0.0.10. The Liberty end of support date for Java SE 8 is
October 2026, fix pack 26.0.0.10. The Liberty
end of support date for Java SE 17 is October 2027, fix pack 27.0.0.10. For more information, see
Removal notices.
Contact the IBM Software Support Center for information
about updates for WebSphere Application Server Liberty Core. The most current information is available from the IBM Software Support Center and Fix Central.
IBM Installation Manager Version 1.8.5 or later is required to update to Liberty fix pack 16.0.0.2 or later.
Through version 19.0.0.8, the minimum acceptable version of IBM Installation Manager is 1.8.5.
As of version 19.0.0.9, the minimum acceptable version of IBM Installation Manager is 1.9.0.
If you want to install Liberty assets from local directory-based repositories or an
instance of the Liberty Asset Repository Service, configure the repositories. For more information
about the Liberty asset repositories, see Installing assets using Installation Manager.
Tip: As an alternative to the procedure that is described in this article, Installation
Manager allows you to use the updateAll command in a response file or on the
command line to search for and update all installed packages. Use this command only if you have full
control over which fixes are contained in the targeted repositories. If you create and point to a
set of custom repositories that include only the specific fixes that you want to install, you should
be able to use this command confidently. If you enable searching service repositories or install
fixes directly from other live web-based repositories, then you might not want to select this option
so that you can select only the fixes that you want to install using the
-installFixes option with the install command on the command
line or the installFixes attribute in a response file.
Procedure
-
For a list of fix packs that are available for WebSphere Application Server Liberty Core
and specific information about each fix, perform the following actions.
- Go to Fix
Central.
- Click Find product.

- Access the live service repository that contains the fix pack, and use web-based updating.
Use
Installation Manager on your local system to update
WebSphere Application Server Liberty Core
with the interim fixes from the live web-based service repositories.
To install a fix pack from a service repository, perform the following actions:
- Log on to your system.
- If you do not already have Installation Manager credential-storage and master-password files
containing your IBM software user ID and password, create
files that will allow you to access the repository.
Note: These are the credentials that you use to
access protected IBM software websites.
Tip: When creating a credential-storage file, append /repository.config at the end
of the repository URL location if the imutilsc command is unable to find the URL
that is specified.
- Stop all servers and applications on the WebSphere Application Server Liberty Core
installation that is being updated.
- Change to the
Installation_Manager_binaries/eclipse/tools directory, where
Installation_Manager_binaries is the installation root
directory for the Installation Manager.

where offering_ID is the offering ID that is listed in Liberty product offerings for supported operating systems.Tips:
New: When you update Liberty, all installed Liberty addons and features are also
updated.
You can install additional addons and features by specifying them on the
user.addon and user.feature properties, as shown in the
following example. Note that the feature short names or symbolic names are separated by double
commas:imcl install com.ibm.websphere.liberty.CORE.ND,embeddablecontainer
-properties user.addon=extendedPackage-1.0,user.feature=portlet-2.0,,portletserving-2.0

You can install assets from instances of the Liberty Asset
Repository Service or local directory-based repositories with or without internet access. Add the
repository URL, directory path, or archive file path on the -repositories
parameter. These repositories are accessed in the order that they are specified. For more
information about these asset repositories, see Installing assets using Installation Manager. To install assets from the IBM
WebSphere Liberty Repository, you must have access to
the internet. To enable access to the Liberty Repository, on the -properties
parameter, set the user.useLibertyRepository option to true
.
The Liberty Repository is the last of the repositories that are accessed during
installation.
- The offering_version, which optionally can be attached to the offering ID
with an underscore, is a specific version of the offering to install
(
16.0.2.20160503_0200
for example).
- If offering_version is not specified, the latest version of the
offering and all interim fixes for that version are installed.
- If offering_version is specified, the specified version of the offering and
no interim fixes for that version are installed.
The offering version can be found attached to the end of the offering ID with an underscore
when you run the following command against the
repository:
imcl listAvailablePackages -repositories repository_URL_or_path
- You can also specify
none
, recommended
or all
with the -installFixes
argument to indicate which interim fixes you want installed
with the offering.
- If the offering version is not specified, the
-installFixes
option
defaults to all
.
- If the offering version is specified, the
-installFixes
option defaults to
none
.
- To install the embeddable EJB container and JPA client, specify the optional
embeddablecontainer
feature after the offering ID, separated by a comma. Note: A removal notice was issued for the embeddable EJB container and JPA
client feature as of the 16.0.0.2 fix pack, so the feature is eligible for future removal. For more
information, see Removal
notices.
The embeddable EJB container is a
Java archive (JAR) file that you can use to run enterprise
beans in a standalone Java Platform, Standard Edition (SE)
environment. You can run enterprise beans by using this embeddable container outside the application
server. The embeddable EJB container is a part of the EJB 3.1 specification and is primarily used
for unit testing enterprise beans business logic.
The JPA client can be used with the
embeddable EJB container to provide Java Persistence API
capability in a Java SE environment.
- Optional: List all installed packages to verify the installation:



./imcl listInstalledPackages -long
imcl.exe listInstalledPackages -long
- Download the file that contains the fix pack from Fix Central, and use local updating.
