When I try to start a session to the IBM Debug Tool my session hangs up.
The IBM Debug Tool internally does a CLSDST and TPX cannot associate the second incoming BIND to an ACT entry.
The TPXLOG will show the message: TPXL0053 BINDLOST - NO ACT ENTRY FOUND - ACB= vtrm-ID, PLU=applid
Use an UNIQUE virtual terminal instead of a GROUP one for this application. This can be done by defining the IBM Debug Tool with TYPE=UNQ in the ACT.
Under user maintenance, the user should have a Transfer option of MULT.
TSO can be on 1 TPX, and IBM Debugger on another TPX session.
TPX must be recycled when you change this parameter.
