oprocd mystic
Согласно документации на 10gR2, oprocd - A UNIX-based process monitor for a cluster. Note that this process will only appear on platforms that do not use vendor clusterware with Oracle Clusterware.
Process Monitor Daemon (OPROCD)—This process is locked in memory to monitor the cluster and provide I/O fencing. OPROCD performs its check, stops running, and if the wake up is beyond the expected time, then OPROCD resets the processor and reboots the node.
Так вот он есть только в 11g на Linux. В 10g он упоминается только в init скриптах. Кто нибудь знает почему это так случилось ?

ОтветитьУдалитьOracle Clusterware for release 10.2.0.4 and above on Linux platforms now uses the Oracle Clusterware Process Monitor Daemon (OPROCD) to monitor the system state, and health of each local cluster node as is currently done on all Unix platforms that do not run 3rd party vendor clusterware.
The OPROCD daemon runs along with the hangcheck-timer module on Linux platforms running Oracle Clusterware release 10.2.0.4 and above (See MetaLink for specific patchset release availability by Linux platform).
