Typical problems and their solution

Things to check first

  • Is there sufficient main memory?
    • SUSE Manager requires at least 4GB (four gigabytes) of main memory
    • Adding swap space is a good idea
  • Is there sufficient disk space?
    • SUSE Manager requires approx 30GB of disk space for a full SLES11SP1 repo
  • Are client and server synchronized on time?
    • Else the certification validation might fail. Run sntp -P no -r pool.ntp.org to synchronize time with ntp.org;
  • Actions don't get scheduled/executed, a number of other things do not work as expected
    • Is Taskomatic running out of memory (can you find "OutOfMemoryError" in /var/log/rhn/rhn_taskomatic_daemon.log)?
    • Give taskomatic more memory by editing /etc/rhn/rhn.conf and adding taskomatic.maxmemory = 2048.

Setup problems

Hostname of the server

    • You cannot change the hostname of the server after setup
    • The hostname must resolve to the correct IP address via DNS
      • Make sure your DNS server is correctly configured

SSL certificate creation fails

    • You must enter a valid country code
      • e.g. UK is invalid, GB is valid

Client does not get activated

    • Often caused by a missing channel assignment:
      • Add Repositories to SUSE Manager
      • Combine Repositories to Channels
      • Assign Channels to Activation Codes
      • Activate the client with an Activation Codes
