When you deploy a study, you may find its status showing as 'Processing' on the 'Manage Studies' page hours or even days later (see screenshot below with study status highlighted in red). The status may remain stuck like this indefinitely, regardless of how fast your caIntegrator server is.
...
The most common cause of this problem is an out of memory error caused by a limitation limited heap space in the size of the heap Java Virtual Machine on the JBoss server instance running caIntegrator. If a study deployment fails due to this error, caIntegrator does not notify the user and instead logs the error in the server.log file located at the following Windows path:
...
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 KB article at:Wiki Markup
The minimum heap space should be set to 4096 MB (4 GB), assuming that your caIntegrator server has this amount of physical memory available._\[insert link here\]_
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 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.
