Update System Property

Using REST you can update System property for one or multiple instances. It is supported only when you are using deployment with TIBCO Enterprise Administrator mode.

Here is a generic cURL example that updates system property for one or multiple instances. 

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=savesystemproperty" -F "INSTANCES=<INSTANCE_1,INSTANCE_2,...,INSTANCE_n>"
 -F "PROPNAME=<PROPNAME_IN_SYSTEMPROPERTIES_FILE>" -F "PROPVALUE=<NEW_PROPVALUE>"
Here,

INSTANCES : Identifies multiple instance names

PROPNAME : The system property name.

PROPVALUE : The system property value
