Passing JVM options

To perform tasks such as attaching a debugger or configuring the garbage collector, pass JVM options to Hyperledger Besu.

Besu passes the contents of the BESU_OPTS environmental variable to the JVM. Set standard JVM options in the BESU_OPTS variable.

For Bash-based executions, you can set the variable for only the scope of the program execution by setting it before starting Besu.

Example

BESU_OPTS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005 \
besu --network=rinkeby
