Description
The deployed BE engine cannot be started in TIBCO Administrator UI.
A fatal error is reported when we initialize the configured channels (TLS enabled).
Error:

Note:
You can start the BE engine successfully in a console by executing the script created for the deployed BE application under $TIBCO_HOME/tra/domain/<domainName>/application/<applicationName>.

Resolution
Root cause:
The environment settings of the Hawk agent are inherited by BE agent. The Hawk agent started with a different Java version (1.8) as the BE agent (11.0). In a Java 1.8 environment the
OS library path includes the sunec shared library (Linux: libsunec.so), which is not compatible with Java 11.
The "java.lang.UnsatisfiedLinkError" reported in a Java 11 applications, when the sunec shared library is included in the configured OS library path.
Solution:
The OS library path variable in the be-engine.tra file depends on the Operating System.
e.g. (Linux)
From:
tibco.env.LD_LIBRARY_PATH=%TPCL_HOME%/lib%PSP%%AS3x_HOME%/lib%PSP%%FTL_HOME%/lib%PSP%%AS_HOME%/lib%PSP%%RV_HOME%/lib/64%PSP%%JVM_LIB_DIR%/server%PSP%%JVM_LIB_DIR%%PSP%%RV_HOME%/lib%PSP%%EMS_HOME%/clients/java%PSP%%TERR_HOME%/lib/x86_64%PSP%%LD_LIBRARY_PATH%
To:
tibco.env.LD_LIBRARY_PATH=%TPCL_HOME%/lib%PSP%%AS3x_HOME%/lib%PSP%%FTL_HOME%/lib%PSP%%AS_HOME%/lib%PSP%%RV_HOME%/lib/64%PSP%%JVM_LIB_DIR%/server%PSP%%JVM_LIB_DIR%%PSP%%RV_HOME%/lib%PSP%%EMS_HOME%/clients/java%PSP%%TERR_HOME%/lib/x86_64

Solution:
- Modify $BE_HOME/bin/be-engine.tra and remove the OS library path variable at the end of the OS library path to avoid that BE application loads the inherited settings of the Hawk agent
- Force deployment in TIBCO Administrator to apply the changes in tra files of the deployed BE applications
The OS library path variable in the be-engine.tra file depends on the Operating System.
