TIBCO Activation Service 1.1.0

Description

Symptoms ->

While installing TAS on a Linux Machine that already has an older version of Java installed, the yum install command does not show any error on the console; however, the following error is seen in the tibco-activation logs [/var/log/tibco/tibco-activate-install.log]:
-------------------------------------------------------------
Error: Java 17 or 21 is required, but has not been detected
-------------------------------------------------------------

Additionally, the README.txt file, which contains the Service URL, is not created in the '/usr/libexec/tib-lm/' directory.


Cause ->

The error is seen when TAS is installed on a Linux Machine that already has an older version of Java installed. TAS requires JAVA 17 in order to function properly. Since the JAVA_HOME is set to Java 1.8, the TAS runs into this error.

An older version of Java is already present on the machine:

2. Upgrade Java version to 17 on the Linux machine.

  1. Install Java 17 on the machine:
    sudo dnf install java-17-openjdk-devel -y

  2. Switch the default Java version to 17: 
    For RHEL server ->
    sudo alternatives --config java

    For Debian-based or Ubuntu system ->
    sudo update-alternatives --config java

    Result would be like:
    -------------------------------------------------------------------------------
    [diksha_gosavi@gasdseudtas1101 jvm]$ sudo alternatives --config java
    There are 2 programs which provide 'java'.

    -------------------------------------------------------------------------------

 

3. Reinstall TAS on the machine:

  1. For RHEL server ->
    sudo yum -y install tibco-activation_1.1.0_x86_64-server.rpm
    sudo yum -y install tibco-activation_1.1.0_x86_64-util.rpm

  2. For Debian-based or Ubuntu system ->
    sudo apt-get -y install ./tibco-activation_1.1.0_x86_64-server.deb
    sudo apt-get -y install ./tibco-activation_1.1.0_x86_64-util.deb


The tib-activate-install logs do not show any error messages
