# The error means that Sentinel is unable to find the necessary Java class in the class library path Sentinel uses. To correct the error, perform the following -

1. Take a back up of the file trkserver in the bin folder of the Sentinel installation folder.
2. Add the following line before the first occurrence of the keyword SENTNEL_CLASSPATH

# This is a temporary fix - For missing DB2 database drivers.
SENTINEL_CLASSPATH=${SENTINEL_CLASSPATH}:${SENTINEL_INSTALL_DIR}/lib/db2/db2jcc.jar:${SENTINEL_INSTALL_DIR}/lib/db2/db2jcc_license_cu.jar
# End of Change - For missing DB2 database drivers

3. Save the file & restart Sentinel.
