How do I increase the heap on Linux?

[jbuszkie]

Not sure if this is the correct forum... but I'm playing around with V9 and The main reason is to increase the heap. How do I do that in Linux? I mostly remember how to in Windows.. but in linux, I have no idea.

Is it a Java setting? is it a Sage setting?

Thanks,

Jim

Ok.. I'll answer my own question! I had to do a google search to find it!

In the startsagecore script in the install directory there is a variable you have to change.

PIDFILE=/var/run/sagetv.pid
HEADLESS=true
JAVAMEM=-Xmx2048m
JAVAOPTS=

The red is what you have to change. Don't forget to stop and restart the server!

I think the correct way is to create/edit sagesettings and put the changes in there. ie, for my setup I have the following in my sagesettings.

export JAVAMEM=-Xmx1024m

If you edit the startsagecore then it will get overwritting when you update.

If sagesettings is not there and you create it, then make sure that you set the execute bit as well.

So I create a file and put the stuff in there?

Do I need the
#!/bin/bash

at the top?

So it looks like

#!/bin/bash
export JAVAMEM=-Xmx1024m

I see that the startsage script calls the sagesettings..

Probably a much better way to do that!
Thanks Sean!

Edit: Cool! It worked fine. Thanks again for that tip!

And for others who might come along this thread: If you are using the Docker install, there is a setting in the container's 'advanced view' to set this.

I'm a novice with Linux but I have my system working fine with v9 and OpenDCT. My JVM max had defaulted to 768 when I installed v9 so I created the script above to set it to 1024. Even though I set it to 1024, when I check in Setup-System Information it shows only 955mb. Is there anything else I should have changed?

I think that's accurate.. there is overhead taken out of the 1024 that doesn't get reported in the UI (which shows max usable space).

Thank you for the clarification. That explains it.
