Upgrading high-availability installations
All servers that are configured for the HA feature must be on the same version. Thus, all servers must be upgraded at the same time.
Before you begin
Note: During the upgrade of HCL Launch , the contents of the appdata/patches directory (including all .jar files) will be appended with
.off, preventing the existing test fixes from being loaded once the HCL Launch Server is started post-installation. All UI test fixes applied to the Tomcat directory will be
wiped by the upgrade and will not be recoverable.
If a text fix received for a reported defect is not fixed in the upgraded version, you may need to open a Support Case to request a new build.
Procedure
- Back up the database.
-
Ensure that no application and generic processes are running.
Open the Dashboard and confirm that no processes are running. If processes are running, you can wait for them to complete or by clicking Cancel in the same row as each process, cancel them. You can use the Message of the Day feature ( ) to notify users of the planned upgrade, and request that they do not start new processes.
-
Download and extract the installation package.
Upgrades are done with the same package used to perform new installations.
-
Shut down the servers.
Warning: Ensure that all servers are stopped. If any servers are accessing the database when the upgrade happens, the upgrade will cause errors.
-
Ensure that each server is stopped and unable to connect to the load balancer.
If a server process is still running, when you install the new version, you see an error that says "A previously installed version of HCL Launch is running. Please shutdown the running HCL Launch and start the installation again."
- Run the server installation script.
-
From the command line, run the server installer program.
- On Windows™, run the install-server.bat file.
- On Linux™, run ./install-server.sh.
Depending on your system settings, you might need to run this file as an administrator. - When prompted for the location of the installation directory,
enter the path to one of the servers.By specifying an existing installation, you are asked if you want to upgrade the current installation. If you answer yes, the script leads you through the upgrade steps.
-
Restart the upgraded server.
Always use service scripts to start or stop the server. See Starting and stopping the server.
- After the first server is back online, upgrade the other servers. After you upgrade the first node, you will not be prompted to upgrade the database when you upgrade the other nodes.
