H.2 Altair Grid Engine (GE)

File/Property	Updates What?	Updated During
`/cm/shared/apps/uge/var/`	head node	hostname/domain change, failover
<GE instance name>`/common/host_aliases`

The default value of $PBS_CONF_FILE in BCM

is /cm/local/apps/ <openpbs or pbspro>/var/etc/pbs.conf

H.4 LSF

File/Property	Updates What?	Updated During
`$LSF_ENVDIR/lsf.conf`	head node	hostname/domain change, failover
`$LSF_ENVDIR/lsf.cluster.`<clustername>	head node	add/remove/update nodes
`$LSF_ENVDIR/lsf.sudoers`	head node	hostname/domain change, failover
`$LSF_ENVDIR/hosts`	cloud-director	add/remove/update cloud nodes
`$LSF_ENVDIR/lsbatch/`<clustername>`/`	head node	add/remove/update queues
`configdir/lsb.queues`
`$LSF_ENVDIR/lsbatch/`<clustername>`/`	head node	add/remove/update nodes
`configdir/lsb.hosts`

The default value of $LSF_ENVDIR in BCM

is /cm/shared/apps/lsf/var/conf/ <clustername>

On each node where the lsfd service runs, CMDaemon creates a symlink /etc/lsf.conf that points to $LSF_ENVDIR/lsf.conf. This is required by LSF daemons.
