There are a number of possible causes of a failure to load libdb2jcct2zos.so. A common error is the absence of the DB2 libraries from the STEPLIB of the WAS server processes. A failure like this can also be a symptom of a larger problem such as the DB2 Universal Driver not being been fully configured in the DB2 system you are accessing.
Check that all the steps for installing the DB2 Universal Driver have been performed for your DB2 system.
The installation instructions for the DB2 Universal
Driver can be found in the DB2 Information Center at
