The most common cause of this problem is an out of memory error caused by a limitation in the size of the heap on the JBoss server 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:

_\[installation root\]\caintegrator2\jboss-4.0.5.GA\server\default\log_

Note that the study's status will continue to show as 'Processing' on the 'Manage Studies' page even after the deployment has failed and the error has been logged.

The heap size is set in the 'run.bat' file located at the following Wuthe following Windows path:

_\[installation root\]\caintegrator2\jboss-4.0.5.GA\bin_

By default, the heap size is set between 256 and 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:

The recommended heap size varies greatly depending on the size of your dataset and the amount of available physical memory on your caIntegrator server.
