representation, de-emphasizing anomalies that can occur at shorter time intervals. This applies
to following probes: Buffer Cache, Data Dictionary Cache, Disk Sort Ratio, Library Cache, and
Redo Log.
For CRITICAL and WARNING thresholds based upon time to work as intended, their values
cannot exceed the amount of time allotted to the timeout period. Otherwise, an UNKNOWN
status is returned in all cases of extended latency, thereby nullifying the thresholds. For this
reason, Red Hat strongly recommends ensuring that timeout periods exceed all timed
thresholds. In this section, this refers specifically to the probe TNS Ping.
Finally, customers using these Oracle probes against a database using Oracle's Multi-Threaded
Server (MTS) must contact Red Hat support to have entries added to the RHN Server's
/etc/hosts file to ensure that the DNS name is resolved correctly.
