Issue:
The following message occurs when issuing the 'Pick' command (PF6) for all of the DC's (Data Collectors) that reside locally to the User Interface:
DBG55095E DC not available,(RC=132).
These same Data Collectors can be addressed remotely from other LPARS, just not from the same LPAR as where the DC's are running.
Cause:
The cause of the 'DBG55095E DC not available,(RC=132)' message in this specific scenerio was due to a bad ACBNAME parameter definition in the VTAM UI APPLs defined to the local LPAR.  
The five RAF UI APPL definitions for the given LPAR all had ACBNAME=DBG004.  
As stated in the RAFUIAPPL  .SOURCE library member, the ACBNAME must start with DBG001 and increase consecutively with each definition (EG. DBG001-DBG009).
Resolution:
Correcting the ACBNAME parameter for the local RAF UI APPL definitions to reflect DBG001-DBG005, and then deactivating / activating the RAF UI APPLS resolved the 
'DBG55095E DC not available,(RC=132)' error message for all of the local DC's, allowing for the 'PICK' (PF6) command to show them as 'Available'.
