But there was no JRE_new folder in the PMP directory, anywhere. I did, however, find one in the ppm file itself (took me a bit to realize that the ppm files themselves were just zip files). So I exctracted it and put it in place under /var/local/ucs/PMP/jre . This let me complete the UpdateManager process. But the service wouldn't start. Error logs stated that the process couldn't find java binary. Looking back in the /var/local/ucs/PMP/jre directory, I found that it's contents had been replaced with a zipfile called 'jre_new.zip' which had not been extracted. So I unzipped it, got it oriented and then was able to continue on my merry way to 12.2 .
