A userApplication failover or degeneration occurred because of an Oracle instance resource failure.
[Case 1]
If there is insufficient space to archive, and data updating processing through monitoring SQL hangs, an oracle resource might fail.
Check the Oracle alert log, so you might be able to detect the cause of the failure.
Also, backup archive logs then reserve enough disk space.
[Case 2]
If monitoring timeout occurs twice in a row, a resource failure will occur. If the following error message is output to syslog, you can determine the cause of this problem:
“ERROR: 0226: Watch Timeout occurred”
Take corrective action on Oracle.
In Oracle instance monitoring of PRIMECLUSTER Wizard for Oracle, if there is no reply from Oracle within a specified time, monitoring timeout will be considered. At the first monitoring timeout, the resource will only enter Warning, however, if it occurs twice in a row, a resource failure will be determined.
