APAR PM96642 is fixed in Rational Developer for System z (RDz) v18.104.22.168 fixpack. This APAR picks up a fix from the Rational Common Licensing (RCL) product, and is not listed as one of the APARs fixed in that fixpack since it is an internal APAR.
The problem described in this APAR will occur if you are using a floating license with RDz, and the Rational Common licensing logger configuration file was not configured when RCL was first installed. The fix for this APAR will allow a restart of the RCL so that the configuration file will be read.
