A “hot” deployment or update is an update to a running application on a running server and the changes are dynamically applied without the need for restarting your application server. If you try to perform a “hot” update to a module containing SCA references, you may find that the module does not function correctly after the deployment, as WESB and WPS ( also IBM Business Process Manager) cache references to EJB stubs pointing to modules registered by the SCA runtime.

You may notice the following errors in your SystemOut.log where you application is installed:

SCA unable to establish connection to SIB/ME in 108 secs.

Internal Error. : org.omg.CORBA.OBJECT_NOT_EXIST: SERVANT_NOT_FOUND

If you notice these errors and your application module is not functioning properly unless you restart your application server, then you most likely will need to update your SCA Feature Pack. The most recent version of the SCA Feature Pack 1.0.1.15 will allow you to perform “hot” updates on modules that contain SCA references, eliminating the need to restart your application server.

You can check your current installed feature pack version my running the WAS_INSTALL_ROOT/bin/versionInfo -maintenancePackages command.

You should see something like the following:
