Hi,

I downloaded WL-OPC v1.9.1 version. I edited in setenv.properties file configuration. But when I use “opc start” command. It gives the following error. Could you help me? How can I start WL-OPC?

Regards.

Hi Can,

This error is the wrong path for java in setenv.properties file configuration.
Because in Linux alternative link using for java path.
If you are using this command in terminal. “echo $JAVA_HOME” then it gives a true java path.
ex: echo $JAVA_HOME --> /usr/lib/java/jdk1.8.0_201
In setenv.properties file JAVA_HOME line change with your full java path.

Then you can start WL-OPC.

Regards.
