Configuring JVM Parameters
You can configure the required JVM parameters such as
the heap size in the jvm.options file in the config/ directory
of your Hazelcast distribution. Use one option per line. You can also
use # at the beginning of the line for comments.
For example, to start Hazelcast with a 8GB heap use the following content
in the jvm.options file:
# JVM Configuration
-Xmx8GYou can also use the JAVA_OPTS environment variable
for ad-hoc configuration option. For example, to start Hazelcast
with a 8GB heap, you can use the following command:
JAVA_OPTS=-Xmx8G bin/jet-startYou can use the JAVA_OPTS also to pass additional properties to Hazelcast:
JAVA_OPTS=-Dhazelcast.operation.thread.count=4 bin/jet-startTo mask sensitive data in logs passed via JAVA_OPTS, use the maskOpts parameter.
maskOpts should contain a comma-separated list of option keys to mask.
This parameter must be included within JAVA_OPTS.
Usage example:
JAVA_OPTS="-Djavax.net.ssl.keyStorePassword=keypassword -Djavax.net.ssl.trustStorePassword=trustpassword -DmaskOpts=javax.net.ssl.keyStorePassword,javax.net.ssl.trustStorePassword"This will produce logs like:
... -Djavax.net.ssl.keyStorePassword=**** -Djavax.net.ssl.trustStorePassword=***
