Chapter 2. Major Corrections

File paths related to the Monitoring feature of RHN Satellite have been rewritten to conform to the Linux Standards Base (LSB). Monitoring files that were once in the /opt directory have been moved to /usr/bin/ for executable scripts, /var/log/ for log files, and /var/lib/ for associated library files.

For example, to execute the script called monitor-queue, instead of typing /opt/notification/scripts/monitor-queue you can now type monitor-queue or /usr/sbin/monitor-queue at a shell prompt.

rhn-proxy and rhn-satellite are no longer running services. All services related to RHN Proxy Server and RHN Satellite functionality (httpd, jabberd, tomcat, Monitoring, Monitoring Scout, and the database service) can be stopped, started, and restarted individually.

You can stop, start, or restart all Satellite services at once using the following command:

 /usr/sbin/rhn-satellite {stop|start|restart}

You can stop, start, or restart Proxy using the following command:

/usr/sbin/rhn-proxy {stop|start|restart}

The default Virtualization Type when creating a kickstart profile has been changed from none (which is no longer an option) to Xen para-virtualized Guest. If you do not intend to creat a kickstart profile for virtual guest, you should leave it at the default and it will not affect your profile.

RHN Satellite no longer supports kickstart distributions located outside of the Satellite server. All distributions must be synced and located on the Satellite server itself.

The Nocpulse home directory has been moved from /home/nocpulse to /var/lib/nocpulse. Nocpulse is now created as system account with uid of less than 500.

An issue has been fixed where Monitoring would fail to run with an external database that had a different name than the database instance name.

Monitoring probes now work even when the SSH daemon has defined banner text.

An issue has been fixed where repomd cache files were broken for custom channels on RHN Proxy on RHEL 5 systems.

To resolve this issue, after reinstallation of Proxy, run the following command:

rm -f /var/spool/rhn-proxy/list/*

Monitoring code has been refactored and all files from the /opt/ directory related to Monitoring have been moved to their proper directories (/etc/nocpulse/, /var/lib/nocpulse/, /var/log/nocpulse/, and /var/log/notification).

Mail for the nocpulse user is now forwarded to root (as defined in the /usr/lib/nocpulse/.forward file).

Monitoring log files now include date and timestamps for every record.

A new configuration option, enable_snapshots, has been added to the /etc/rhn/rhn.conf file. This allows administrators to enable or disable capturing system snapshots. By default, snapshots are enabled; to disable it, edit the enable_snapshots option to the following:

 enable_snapshots=0

RHN Satellite 5.3.0 now has the ability to purge system snapshots via the API.

Subsystem script /etc/rc.d/init.d/osa-dispatcher now returns correct status.

TNSping monitoring probe has been rewritten to work with Oracle Instant Client.

When using Satellite with SELinux enabled, if /var/satellite/ is changed to an NFS mount after the initial installation, you must run the following command:

/usr/sbin/setsebool -P spacewalk_nfs_mountpoint 1
