  4. 5008 - Out of Balance: High

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 DA-MPs traffic is unbalanced and processing a higher than average load, the IPFE server displays the 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 indicate the IPFE traffic on a DA-MP server is unbalanced for some reason. There is no impact to traffic or connections and this alarm does not cause disconnection or congestion. As new connections are established, and statistics indicate the server is no longer overloaded, alarm 5008 clears.

Diagnostic Information:

Collect the following DATA before contacting My Oracle Support 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, and then Server page.
  3. Consult the application server's documentation for recovery steps.
  4. It is recommended to contact My Oracle Support if further assistance is needed.
