We have a 4.2.1.9 server under OS/390. We need to upgrade to 4.2.3.0 to fix a memory leak. The anonymous FTP server for TSM maintenance has file saying: "Please refer to your readme for the instructions to get to the password protected ftp site to get the latest fix". SYS1.SAMPLIB(ANR4421) seems to be the README file for the 4.2.1 server, but I can't find any information on the password protected FTP site in that PDS member. What am I missing here?
