Troubleshooting

Various issues arise as users work with the probe. Troubleshooting information is provided to help you diagnose and resolve such issues.

Fails to Connect

The Probe for CA Spectrum (CORBA) fails to connect to the SpectroSERVER when configured with a host file. You may receive the following message when configuring a host file:

07/01/10 10:36:39: Debug: [1 server1] Connecting to SpectroServer
07/01/10 10:36:42: Debug: [1 server1] Exception =
org.omg.CORBA.OBJECT_NOT_EXIST:   vmcid: 0x0  minor code: 0  completed: No
07/01/10 10:36:42: Error: Exception thrown when attempting to start CORBA service:
07/01/10 10:36:42: Error: Unable to access CORBA service, head is shutting down

This indicates that there is a connection issue between the probe and the SpectroSERVER. A possible reason is that the probe cannot find the location of the SpectroSERVER specified in the ca_spectrum_corba_host.xml host file.

To resolve this problem, set the domain property in host file to the SpectroSERVER host FQDN which is reachable from probe host.

For the information about the required format of the connection information in the host file, see Using the host configuration file.

Migration Guidelines

The table below provides a comparison between older version of CA Spectrum probe that are useful when migrating to new version of the probe.

Table 1. Migration Changes
Existing: nco_p_spectrum_corba_v9	New: nco_p_ca_spectrum_corba	Changes
AllAlarmsOnRestart	InitialResync	This property takes the following values: false: The probe only retrieves alarms generated since the last connection. true: The probe retrieves all active alarms; no alarm filter is applied by the probe. The default is false.
EventRetry	EventRetryCount	Name change
OS.Host	OSHost	Name change
OS.Password	OSPassword	Name change
OS.Port	OSPort	Name change
OS.Username	OSUsername	Name change
Retry	SpectrumRetry	Use this property to specify whether the probe attempts to reconnect to a SpectroSERVER after losing the connection. This property takes the following values: true: The probe's connection waits for connection to reestablish with the SpectroSERVER. false : The probe does not wait for connection to reestablish with SpectroSERVER. The default is true.
ResyncOnFailOver	ResyncOnFailOver	Use this property to specify whether the probe performs a resynchronization during the SpectroSERVER failover process. This property takes the following values: true: The probe performs a resynchronization. false: The probe does not perform a resynchronization. The default is false.
ResyncOnPrimaryOnly	ResyncOnPrimaryOnly	Use this property to make the probe resynchronize with the primary SpectroSERVER only during the SpectroSERVER failover process. This property takes the following values: true: The probe performs a resynchronization with the primary SpectroSERVER only. false: The probe resynchronizes with either SpectroSERVER. The default is false.
