Db2 v11.5.9.0 installation: error while loading shared libraries: libaws-cpp-sdk-transfer.so

On Red Hat 8.8 *Rocky Linux 8.8* I have Db2 v11.5.8.0 installed and database is working fine. 1. Today I downloaded v11.5.9.0 and unpacked the tar file. 2. I executed db2prereqcheck and all prerequisites are met. Successful. 3. Installed Db2 using db2_install command. Successful. 4. Upgraded instance with db2iupdt command. Successful. 5. Then I tried to start up an instance with db2start and error: *db2start: error while loading shared libraries: libaws-cpp-sdk-transfer.so: cannot open shared object file: No such file or directory* It looks some library is missing. I try to search the web, but can't find how to install this library. Any idea?
