If your process crashes with "Java heap space" error, your Runtime experiences a lack of memory :

You can try to increase the STAMBIA_MAX_MEMORY in initvariables script :

set STAMBIA_INIT_MEMORY=32m
set STAMBIA_MAX_MEMORY=512m
set STAMBIA_STACK_SIZE=256k

But sometimes, that won't be enough. You'll have to check the operations done in your process. Seek for the SQL operations and maybe reduce the fetch batch size parameter. It can also happens if you handle a huge XML file. In that case, you probably need to increase the STAMBIA_STACK_SIZE parameter.

Thanks for these informations.

I still have a question about the 3 memory parameters (in initvariables script), with the local runtime.
When I restart Stambia after modifying the initvariables file to increase values, this file is reinitialized, and new values are erased by default ones.

How can I keep permanently those new values?

Hi,
Indeed, each time the Designer restarts, the local Runtime's files are reset by default.
Simply add the file path to the stambiaRuntime/properties/protection.rules and it will no longer be reset.
