Error Information
ERROR STATUS
(W#16#...)
Explanation
0 0000 Connection was able to be established
0 7000 Call with REQ=0, establishment of connection not initiated
0 7001 First call with REQ=1, connection being established
0 7002 Follow-on call (REQ irrelevant), connection being established
1 8086 The ID parameter must not have value of zero.
0 8087 Maximal number of connections reached; no additional connection possible
1 809B The local_device_id in the connection description does not match the target
CPU.
1 80A3 Attempt being made to re-establish an existing connection
1 80A7 Communications error: you have called TDISCON before TCON was complete.
TDISCON must first complexly terminate the connection referenced by the ID.
1 80B3 Inconsistent parameters:
Error in the connection description
Local port (parameter local_tsap_id)is already present in another
connection description
ID in the connection description different from the ID specified as parameter
1 80B4 When using the protocol variant ISO on TCP (connection_type = B#16#12) for
passive establishment of a connection (active_est = FALSE), you violated one
or both of the following conditions: "local_tsap_id_len >= B#16#02" and/or
"local_tsap_id[1] = B#16#E0".
1 80C3 Temporary lack of resources in the CPU.
1 80C4 Temporary communications error:
The connection cannot be established at this time.
The interface is receiving new parameters.
1 8722 CONNECT parameter: Source area invalid: area does not exist in DB
1 8732 CONNECT parameter: The DB number lies outside the CPU-specific number
range.
1 873A CONNECT parameter: Access to connection description not possible (e.g. DB
not available)
1 877F CONNECT parameter: Internal error such as an invalid ANY reference
