Application server update (Apache Tomcat)

The installer updates the application server for all INUBIT components.

If there is a newer Tomcat version as the current one, the patch installer automatically creates a backup of the Tomcat directory and installs the new Tomcat version. The following steps are performed:

The current Tomcat directory is moved to: <SUITE-INSTALL-DIR>/inubit/apache-tomcat-<version>
The new Tomcat version is installed in the following directory: <SUITE-INSTALL-DIR>/inubit/apache-tomcat

After the update

Driver: No adjustments for drivers etc. are required. be made
Link: In the <SUITE-INSTALL-DIR>/inubit/inubit_setenv.[sh|bat] file, the entry for "CATALINA_HOME" points to the newly added Tomcat installation folder.
Backup: The previous Tomcat installation is located in the folder <SUITE-INSTALL-DIR>/inubit/apache-tomcat-<version>.

Manual Apache Tomcat update

The installer regularly provides officially tested updates for the bundled Tomcat instance. If your compliance requirements regarding critical CVEs demand faster response times, you can upgrade the Tomcat version yourself at any time.

Tomcat is highly backward-compatible, so such updates generally proceed without issues. However, since we cannot pre-verify your specific version, you perform this step at your own responsibility. We recommend reverting to our verified reference environment if you encounter unexpected behavior or once our official patch is released.

Prerequisites

INUBIT Process Engine is shutdown.

Proceed as follows

Place the new Apache Tomcat on your system.
In the file <SUITE-INSTALL-DIR>/inubit/inubit_setenv.[sh|cmd] set the value of the environment variable CATALINA_HOME to the newly installed Apache Tomcat folder.
Start the Process Engine.

In the event of problems, you can revert to the previous Tomcat version at any time by resetting the path in <SUITE-INSTALL-DIR>/inubit/inubit_setenv.[sh|cmd] to the previously used directory.
