IO execution not allowed at session initialization

Hello!

I installed on ZOS 2.5 the Natural 9.2.3 and the NDV 9.2.3 + CICS TP 6.2, but I have the following problem when I try to MAP any system entry point via NaturalOne:

This error came out only if I try to send STACK=(LOGON LIB) parameter.

Got new connection
Client USERID arrived
Worker task active, SID=SYSTEMID, client: USERID
ClientDir: Client USERID already stored in Client Directory.
Session runtime connect successful, Lib:
PrintError: IO execution not allowed at session initialization
Cancel IO, A(IO-Buffer)=1E7CC268
Cancel IO done, A(IO-Buffer)=00000000
Connection error, cancel session SYSTEMID
Worker task disconnect, client: USERID
Free LTCB…and finish

Without STACK parameter I got this message:

Got new connection
Client USERID arrived
Worker task active, SID=SYSTEMID, client: USERID
ClientDir: Client USERID already stored in Client Directory.
Session runtime connect successful, Lib:
Exec IO, bufflen:2443

Later when the NDV try to cancel the connected sessions the following messages are arrives:

I’m new in ADABAS/Natural system programming.

Thank you for your help in advance!

Do you have Natural Security? It’s liklely something is running at startup that is trying to do I/O - PRINT, INPUT,WRITE,DISPLAY,etc. Check the user and library profiles to see what the startup program is set to.
