ESB 5.0.0 is using the Carbon Kernel version 4.4.5 and in the
"wso2server.sh" carbon file, it will check the Java version like below and
assign the values of the VM parameters to the "JVM_MEM_OPTS" variable,
according to the java version. Then use the "$JVM_MEM_OPTS" parameter in
the
system property section (refer [1])
if [ -z "$JVM_MEM_OPTS" ]; then
java_version=$("$JAVACMD" -version 2>&1 | awk -F '"' '/version/ {print
$2}')
JVM_MEM_OPTS="-Xms256m -Xmx1024m"
if [ "$java_version" \< "1.8" ]; then
JVM_MEM_OPTS="$JVM_MEM_OPTS -XX:MaxPermSize=256m"
fi
fi
.........................
while [ "$status" = "$START_EXIT_STATUS" ]
do
$JAVACMD \
-Xbootclasspath/a:"$CARBON_XBOOTCLASSPATH" \
$JVM_MEM_OPTS \
Without creating a new server for ESB 5.0.0 (Carbon Kernel 4.4.5), we can
use the same CarbonServer44 component.
We can check the JAVA version and according to that, we can set the
relavent VM parameters.
I think that is the best way to handle this issue, without introduce a new
CarbonSever vertion inside the DevStudio.
