Update JVM Property

Using REST you can update the JVM Property. It is supported only when you are using deployment with TIBCO Enterprise Administrator mode.

Here is a generic cURL example that updates the JVM Property. 

curl -u <USER>:<PASSWORD> -X POST -H "Accept: application/json" -H "Content-Type: multipart/form-data" -v 
"<BROKER_URL>:<BROKER_PORT>/livecluster/rest/v1/sf/engines/<DAEMON_ID>/<ENGINE_INSTANCE>/archives" -F 
"archiveFile=@<ARCHIVE_FILE>" -F "COMMAND=savejvmproperty" -F "INSTANCES=<INSTANCE_1,INSTANCE_2,...,INSTANCE_n>" -F 
"PROPNAME=<PROPNAME_IN_JVMPROPERTIES_FILE>" -F "PROPVALUE=<NEW_PROPVALUE>"
Here,

INSTANCES : Identifies multiple instance names.

PROPNAME : The JVM property name.

PROPVALUE: The JVM property value
