Migrating application database from H2 to Postgres

Hi @flamber

Thanks for the prompt answer. I was actually just reading this article on memory as i did not know why it started with such low memory and yes it was taking forever to start up.

Now I have ExecStart=/usr/bin/java -Xms1g -Xms2g -jar /opt/metabase/metabase.jar.

Still it starts up pretty slow... Actually started it about 10 minutes ago and still not up, I do not see any messages in the log that will show me if it is up or not, I basically check lsof -i tcp:3000 to see the port is listening and then sit and refresh my browser... very frustrating and I wish i could see some log or something to tell me if it is up and working or if there are issues.

I already have followed the instructions in the last link you have sent and it is setup as a service.

I did not fully understand the article on PRNG and the link provided: https://ruleoftech.com/2016/avoiding-jvm-delays-caused-by-random-number-generation
