5007 - Out of Balance: Low
- Alarm Group:
- IPFE
- Description:
- Traffic statistics reveal an application server is processing lower than average load. For example, if a TSA has three application servers, but the IPFE has only two connections open, then one of the application servers receives no traffic and thus is considered "underloaded."
- Severity:
- Minor
- Instance:
- IP address of the application server
- HA Score:
- Normal
- Auto Clear Seconds:
- N/A
- OID:
- ipfeIpfeBackendUnderloadedNotify
- Cause:
-
The IPFE has an algorithm to calculate the average traffic load of the DA-MP application servers, at times the traffic on a DA-MP server may outside of the average range. When an IPFE detects DA-MPs traffic is unbalanced and processing a lower than average load, the IPFE server displays the 5007 alarm.
Few of the causes the IPFE to raise this alarm are:
- A new DA-MP server has just been added to a cluster.
- A DA-MP has just been stopped for maintenance or some other reason.
- The activated traffic rate is to low.
These alarms are not harmful to the system, and indicates the IPFE traffic on a DA-MP server is imbalanced for some reason. There is no impact to traffic or connections and this alarm does not cause disconnection or congestion. As new connections get established, and statistics indicate the server is no longer under loaded, alarm 5007 gets cleared.
- Diagnostic Information:
-
Collect following data before contacting My Oracle Support for assistance.
- Export alarm history.
- grep * /proc/net/xt_recent* > xt_recent1_$(hostname)
- grep * /proc/net/xt_recent*/*> xt_recent2_$(hostname)
- tr.cat ipfe.STK>ipfeSTK_$(hostname)
- iqt -pE IpfeOption>IpfeOption_$(hostname)
- iqt -pE IpListTsa>IpListTsa_$(hostname)
Recovery:
- None required. Underloaded application servers do not impact traffic processing. This alarm clears when traffic statistics reveal the application server is no longer underloaded.
- It is recommended to contact My Oracle Support if further assistance is needed.
