Observe the following service restrictions for Oracle Solaris Cluster configurations:
Routing protocols might inadvertently broadcast the cluster interconnect as a publicly reachable network to other routers, despite the setting of the IFF_PRIVATE flag on the interconnect interfaces.
Routing protocols might interfere with the failover of IP addresses across cluster nodes that impact client accessibility.
Routing protocols might compromise proper functionality of scalable services by accepting client network packets and dropping them, instead of forwarding the packets to other cluster nodes.
Install servers – Do not use an Oracle Solaris Cluster configuration to provide a highly available installation service on client systems.
These numbers are reserved for the Oracle Solaris Cluster daemons rgmd_receptionist, fed, and pmfd, respectively.
If the RPC service that you install also uses one of these program numbers, you must change that RPC service to use a different program number.
Scheduling classes – Oracle Solaris Cluster software does not support the running of high-priority process scheduling classes on cluster nodes. Do not run either of the following types of processes on cluster nodes:
Processes that run in the time-sharing scheduling class with a high priority
Processes that run in the real-time scheduling class
Oracle Solaris Cluster software relies on kernel threads that do not run in the real-time scheduling class. Other time-sharing processes that run at higher-than-normal priority or real-time processes can prevent the Oracle Solaris Cluster kernel threads from acquiring needed CPU cycles.
