  • Increase Heap Memory for NotArb:
  • Add Logging:
  1. Configurations
  2. Shell Scripts

run-bot.sh

PreviousShell ScriptsNextrun-jupiter.sh

Last updated 5 months ago

You can adjust the default run-bot.sh:

1

Navigate to your notarb-unix folder

Use cd to navigate inside the notarb-unix folder

2

Open the run-bot.sh using nano

Run the command nano run-bot.sh

3

Change any of the settings below

4

Save and exit

Forgot how to use Nano? 

#!/bin/bash

# The path to the bot config file (required)
export bot_config_path="./bot-config.toml"

# Move to the correct workdir to prevent path issues
cd "$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"

# Source the notarb_java.sh script with the specified VM arguments
# We highly recommend you increase the -Xmx value to better fit your system. Refer to other VM args here:
# https://docs.oracle.com/en/java/javase/22/docs/specs/man/java.html#standard-options-for-java
. "./libs/notarb_java.sh" \
    -server \
    -Xms256m -Xmx2048m \
    -XX:+UseSerialGC

Increase Heap Memory for NotArb:

  • -Xms256m Sets the initial heap size to 256 MB. This specifies the starting amount of memory the JVM will allocate for the application, ensuring it has at least 256 MB from the beginning.

  • -Xmx2048m argument increases the maximum heap memory allocated to the Java Virtual Machine (JVM) to 2048 MB (2 GB). Adjusting this value allows you to control how much memory the Java application can use.

    • Other values you can use:

      • 1g = 1 GB

      • 1024m = 1 GB / 1024 MB

  • -XX:+UseSerialGC specifies a garbage collector configuration for the JVM, in this case enabling the Serial Garbage Collector, which is suitable for small applications or those with single-threaded memory allocation patterns.

Add Logging:

You can add logging by adding 2>&1 | tee -a notarblogs.txt at the end of -XX:+UseSerialGC

Example: -XX:+UseSerialGC 2>&1 | tee -a notarblogs.txt

This will generate a notarblogs.txt file where all the logs will be saved. You can use this for debugging purposes.
