java heap size error in Business central 7.x

[Meli]

hello Team:

I have got  java heap size error during validating a rule in Business central 7.x UI. I am using wildfly 19.0.0 and modified vi /opt/wildfly19/bin/standalone.conf

as following 

JAVA_OPTS="-Xms1G -Xmx1Gm -XX:MetaspaceSize=512M -XX:MaxMetaspaceSize=1024m -Djava.net.preferIPv4Stack=true"

I set xms and xmx to 1G however, still having the issue.my question is 

1 what is the recommended size to set on xms and xmx?

2 is there any other solution for this issue 

thanks

[Meli]

can someone look into the above issue?

thank you

I don't know the right heap size for this , but the following below did help me.

-Xms64m -Xmx1G -XX:MetaspaceSize=2G -XX:MaxMetaspaceSize=2G -Djava.net.preferIPv4Stack=true

Also for me even after setting in the standalone.conf the value wasn't reading. Make sure the initial part of the log prints the value you gave and not the previous one. For me I had to set an  environment variable of name JAVA_OPTS with above value for it to really work. If you look the standalone.conf it is written to read the environment variable first and if not available then from configuration.

But if you just had to make some POCs for testing or working on local you could use the docker image available.If you use a showcase image it already comes with prebuilt users and role and needs no configuration to run. Up the kie workbench and kie server with following commands.

docker run -p 8080:8080 -p 8001:8001 -d --name drools-wb jboss/drools-workbench-showcase:latest

docker run -p 8180:8080 -d --name kie-server --link drools-wb:kie-wb jboss/kie-server-showcase:latest

if the business central gets slow while running on containers increase the resource allocation for docker.

Hope it helps.
