hi,guys.
i meet some problems.
i can't logon TSO .
here is the system message:
LCL701 UNABLE TO ESTABLISH SESSION - INIT SELF FAILED WITH SENSE 08570002

Hello,

Suggest you call your help desk or technical support group to resolve your problem.

The 08570002 indicates the application (TSO you tell us) has not opened the ACB in VTAM. This could be you attempting to access TSO before TSO is available, or your site shut down TSO for some reason, or your site shut down your terminal LU for some reason -- there's plenty of reasons why you'd get this error.
