PingGateway 2024.9

Set up environment variables and system properties

Configure environment variables and system properties as follows:

  • By adding environment variables on the command line when you start PingGateway.

  • By adding environment variables in $HOME/.openig/bin/env.sh, where $HOME/.openig is the instance directory. After changing env.sh, restart PingGateway to load the new configuration.

Start PingGateway with a customized router scan interval

By default, PingGateway scans every 10 seconds for changes to the route configuration files. Any changes to the files are automatically loaded into the configuration without restarting PingGateway. For more information about the router scan interval, refer to Router.

The following example overwrites the default value of the Router scan interval to two seconds when you start up PingGateway:

  • Linux

  • Windows

$ IG_ROUTER_SCAN_INTERVAL='2 seconds' /path/to/PingGateway-2024.9.0/bin/start.sh
C:\IG_ROUTER_SCAN_INTERVAL='2 seconds'
C:\start.bat %appdata%\OpenIG

Define environment variables for startup, runtime, and stop

PingGateway provides the following environment variables for Java runtime options:

IG_OPTS

(Optional) Java runtime options for PingGateway and its startup process, such as JVM memory sizing options.

Include all options that are not shared with the stop script.

The following example specifies environment variables in the env.sh file to customize JVM options and keys:

  • Linux

  • Windows

# Specify JVM options
JVM_OPTS="-Xms256m -Xmx2048m"

# Specify the DH key size for stronger ephemeral DH keys, and to protect against weak keys
JSSE_OPTS="-Djdk.tls.ephemeralDHKeySize=2048"

# Wrap them up into the IG_OPTS environment variable
export IG_OPTS="${IG_OPTS} ${JVM_OPTS} ${JSSE_OPTS}"
C:\set "JVM_OPTS=-Xms256m -Xmx2048m"
C:\set "JSSE_OPTS=-Djdk.tls.ephemeralDHKeySize=2048"
C:\set "IG_OPTS=%IG_OPTS% %JVM_OPTS% %JSSE_OPTS%"
JAVA_OPTS

(Optional) Java runtime options for PingGateway include all options that are shared by the start and stop script.
