Receiving the following message wait on the AS/400 when performing an XCOM SSL file transfer initiate from a Linux/UNIX server to AS/400:
LBE7204 message "Application error. MCH0601 unmonitored by CAXC2TCP at statement 0000000001, instruction X'0000'"
if the MCH0601 message is preceded by
XCM6231 Information 00 06/05/20 20:37:34.688595 XCOMMSG3 XCOM3 006E XCOMTSLV XCOM3 0284
Message . . . . : Unknown TP: DISCOVER
The cause of the message is due to having set parameter TRNENCRL_CIPHER= to something else other than TRNENCRL_CIPHER=COMPAT. XCOM AS/400 i5/OS supports only TRNENCRL_CIPHER=COMPAT. This applies to transfers initiated from Linux/UNIX/Windows.
On Linux/UNIX/Windows change the parameter to TRNENCRL_CIPHER=COMPAT and the transfer to XCOM r11.0 on AS/400 i5/OS will not receive the MCH0601 message.
XCOM on Linux/UNIX/Windows has a parameter TRNENCRL_CIPHER, the only value supported by XCOM AS/400 i5/OS is TRNENCRL_CIPHER=COMPAT. If another value is specified, and an error occurs (for example FILE_OPTION=CREATE and the file already exists on AS/400 i5/OS) we will see a job on AS/400 i5/OS waiting with a MCH0601 message. You must reply to this message.
