By default, the heap size, which is dynamically allocated, is set at a minimum of 256 MB and a maximum of 512 MB, which is not nearly enough when deploying studies with large datasets. For instructions on how to modify the heap size by editing 'run.bat', please refer to the following page from the caIntegrator local installation guide:

The minimum heap space should be set to 4096 MB (4 GB), assuming that your caIntegrator server has this amount of physical memory available.

The recommended heap size varies greatly depending on the size of your dataset and the amount of available physical memory on your caIntegrator server. For reference, in for a dataset containing 500 Affymetrix CEL files that are approximately 16GB in combined size, the minimum heap size required for the study deployment to complete successfully is 15 GB.

Ideally, caIntegrator should be run on a dedicated server, with the heap size set as close as possible to the amount of available physical memory without destabilizing the underlying operating system.
