Troubleshooting

Use this section to diagnose any problems you have with this scenario.

CICS® TG fails to start up

Check the CICS TG log file. If you see the following message:

CTG8491E CTG910   Unable to read key ring CTGRING reason = java.io.IOException: Hardware error from call CSNBRNG returnCode 12reasonCode 0
CTG6513E CTG910   CICS Transaction Gateway failed to initialize

make sure ICSF is running before you start up CICS TG.

SSL requests fail

If you see the following error in the log:

FINER: Hardware error from call CSNBRNGL returnCode 12 reasonCode 0

make sure ICSF is running without any errors.

SSL handshake errors

Run an SSL trace on the Java™ client and Gateway daemon by specifying the Java override:

-Djavax.net.debug=ssl,handshake

-Djavax.net.debug=ssl,handshake,verbose

For CICS TG the output goes to the error log. The Java client output goes to the standard output stream.

Unsupported cipher

The level of JSSE determines which ciphers are supported. For example, Java 7 supports SSL_RSA_WITH_AES_128_CBC_SHA.
