Approach
In all TIBCO ActiveMatrix installations, the path to JRE home is specified in the CLASSPATH.tra files in the TIBCO_HOME
directory. When a new TIBCO host is created, a TIBCO_CONFIG_HOME
directory is created, and all the host and node files in this TIBCO_CONFIG_HOME
directory point to the CLASSPATH.tra files in the corresponding TIBCO_HOME
directory.
- One or more
TIBCO_CONFIG_HOME
directories can point to the sameTIBCO_HOME
directory. - A single
TIBCO_CONFIG_HOME
can contain multiple "TIBCO ActiveMatrix Administrator Instances" pointing to differentTIBCO_HOME
directories.
The following diagram illustrates the relationship between the files in the two directories. In this diagram, the:
- Diamond shaped nodes are from
TIBCO_CONFIG_HOME
and oval shaped are fromTIBCO_HOME
. - Dark colored nodes are modified during the update to JRE 1.8.
Updating the JRE path in the common CLASSPATH.tra files in the TIBCO_HOME
directory updates the JRE version for all the hosts and nodes in the TIBCO_CONFIG_HOME
directories pointing to it. Any new node instance created after that also uses JRE 1.8.
TIBCO_HOME
level, and not at an individual TIBCO_CONFIG_HOME
level. This means that when .tra files in TIBCO_HOME
are updated all the TIBCO hosts and nodes in different TIBCO_CONFIG_HOME
directories that point to a particular TIBCO_HOME
is automatically updated to use JRE 1.8.
