If you installed Oracle binaries for Oracle versions 10g or later on shared disks, you must disable the Oracle clustering daemon.
Oracle versions 10g and later provide a clustering daemon called Oracle Cluster Synchronization Service Daemon (CSSD). If the Oracle binary files are on a shared storage, the init command to start the daemon may result in an error. Because a VCS cluster for Oracle does not require this daemon, Veritas recommends you to disable the daemon.
