Clean up Default WESB System Applications. (3 of 285 technotes for 2015)

Several system applications are provided as part of the vanilla installation of WebSphere Enterprise Service Bus (WESB). However, not all of the default system applications are required for every WESB runtime topology. In an effort to reduce the number of ear files in the WESB environment the below 9 applications may be removed without any adverse effect to WESB environment  Eight/Nine of the applications are related to Business Space and one application is a RAL (Remote Artifact Loader) app.  I recently performed this clean up on a WESB 7.5 environment with excellent success.  Please note that if you are using Business Space, or RAL- do not remove these applications.
The following 9 WESB System Application Ears can be removed:
Business Space Applications

1. BPMAdministrationWidgets_esb_env2.AppTarget
2. BSpaceEAR_esb_env2.AppTarget
3. BSpaceForms_esb_env2.AppTarget
4. BSpaceHelp_esb_env2.AppTarget
5. PageBuilder2_esb_env2.AppTarget
6. REST Services Gateway
7. REST Services Gateway Dmgr
8. mm.was_esb_env2.AppTarget
9. wesbWidget_esb_env2.AppTarget
10. RemoteAL61 (Remote Artifact Loader)
