FTP Server Fails to Start - Initialization Failure

Troubleshooting

Problem

FTP Server fails to start because TCP3D2C RC1009 and TCP12F0.

Resolving The Problem

FTP Server fails to start. FTP server joblog shows the following message:

TCP12F0 - FTP server initialization failure.

The WRKREGINF command shows all of the following FTP exit points:
QIBM_QTMF_CLIENT_REQ,
QIBM_QTMF_SERVER_REQ,
QIBM_QTMF_SVR_LOGON,
QIBM_QTMF_SVR_LOGON,
QIBM_QTMF_SVR_LOGON and no exit programs defined.

Removing and reinstalling the FTP exit points did not fix this problem.

Further review of the FTP server joblog shows the following message before message
TCP3D2C: TCP3D2C - Secure connection error, return code -1009 ( UNUSED).

RC1009 can be caused by having a certificate (that does not exist) assigned to the FTP
server application ID.

Certificate assignments are stored in QUSRSYS/QYCDCERTI. Check the certificate
assignment in DCM.

Because SSL is not configured (as a result not used), SSL was disabled using the
CHGFTPA ALWSSL(*NO) command.

The server will then start successfully.
