5008 - Out of Balance: High

Alarm Group:

IPFE

Description:

Traffic statistics reveal an application server is processing higher than average load and does not receive new connections.

Severity:

Minor

Instance:

IP address of the overloaded application server.

Note:

When traffic statistics indicate the application server is no longer overloaded, this alarm clears.

HA Score:

Normal

Auto Clear Seconds:

N/A

OID:

ipfeIpfeBackendOverloadedNotify

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 reaches outside of the average range. When an IPFE detects that a DA-MPs traffic is unbalanced, processing a higher than average load, the IPFE server raises 5008 alarm.

Few of the causes for 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 high.

These alarms are not harmful to the system, and indicates that the IPFE traffic on a DA-MP server is imbalanced for some reason. There is no impact to traffic or connections and this alarm will not cause disconnection or congestion. As new connections get established, and statistics indicate the server is no longer overloaded, alarm 5008 gets cleared.

Diagnostic Information:

Collect the following DATA before contacting My Oracle Support (MOS) for assistance.

1. Export alarm history.
2. grep * /proc/net/xt_recent* > xt_recent1_$(hostname).
3. grep * /proc/net/xt_recent*/*> xt_recent2_$(hostname).
4. tr.cat ipfe.STK>ipfeSTK_$(hostname).
5. iqt -pE IpfeOption>IpfeOption_$(hostname).
6. iqt -pE IpListTsa>IpListTsa_$(hostname).

Recovery:

1. IPFE monitors traffic statistics and does not assign connections to the overloaded application server until statistics indicate the server is no longer overloaded.
2. Check the status of the application servers by navigating to the Status & Manage > Server page.
3. Consult the application server's documentation for recovery steps.
4. It is recommended to contact My Oracle Support.
