Conventions used in this guideAll probe guides use standard conventions for operating system-dependentenvironment variables and directory paths.

Operating system-dependent variables and paths

All probe guides use standard conventions for specifying environment variablesand describing directory paths, depending on what operating systems the probe issupported on.

For probes supported on UNIX and Linux operating systems, probe guides use thestandard UNIX conventions such as $variable for environment variables andforward slashes (/) in directory paths. For example:

$OMNIHOME/probes

For probes supported only on Windows operating systems, probe guides use thestandard Windows conventions such as %variable% for environment variables andbackward slashes (\) in directory paths. For example:

%OMNIHOME%\probes

For probes supported on UNIX, Linux, and Windows operating systems, probeguides use the standard UNIX conventions for specifying environment variablesand describing directory paths. When using the Windows command line withthese probes, replace the UNIX conventions used in the guide with Windowsconventions. If you are using the bash shell on a Windows system, you can use theUNIX conventions.

Note: The names of environment variables are not always the same in Windowsand UNIX environments. For example, %TEMP% in Windows environments isequivalent to $TMPDIR in UNIX and Linux environments. Where such variables aredescribed in the guide, both the UNIX and Windows conventions will be used.

Operating system-specific directory names

Where Tivoli Netcool/OMNIbus files are identified as located within an archdirectory under NCHOME or OMNIHOME, arch is a variable that represents youroperating system directory. For example:

$OMNIHOME/probes/arch

The following table lists the directory names used for each operating system.

Note: This probe may not support all of the operating systems specified in thetable.

Firewall considerationsWhen using CORBA probes in conjunction with a firewall, the firewall must beconfigured so that the probe can connect to the target system.

Most CORBA probes can act as both a server (listening for connections from thetarget system) and a client (connecting to the port on the target system to whichthe system writes events). If you are using the probe in conjunction with a firewall,you must add the appropriate firewall rules to enable this dual behavior.

There are three possible firewall protection scenarios, for which you mustdetermine port numbers before adding firewall rules:1. If the host on which the probe is running is behind a firewall, you must

determine what remote host and port number the probe will connect to.2. If the host on which the target system is running is behind a firewall, you must

determine the incoming port on which the probe will listen and to which thetarget system will connect.

3. If each host is secured with its own firewall, you must determine the followingfour ports:a. The outgoing port (or port range) for the probe.b. The hostname and port of the target system.c. The outgoing port on which the target system sends events if the probe is

running as a client.d. The incoming port on which the probe listens for incoming events.

Note: Most, but not all, CORBA probes listen on the port specified by theORBLocalPort property. The default value for this property is 0, which means thatan available port is selected at random. If the probe is behind a firewall, the valueof the ORBLocalPort property must be specified as a fixed port number.

CORBA probes that use EventManager or NotificationManager objects may usedifferent hosts and ports from those that use NamingService and EntryPointobjects. If the probe is configured to get object references from a NamingService orEntryPoint object, you must obtain the host and port information from the systemadministrator of the target system. When you have this information, you can addthe appropriate firewall rules.

Data acquisitionEach probe uses a different method to acquire data. Which method the probe usesdepends on the target system from which it receives data.

The Probe for Huawei N2000 (CORBA) gathers events from the Huawei N2000using a Common Object Request Broker Architecture (CORBA) interface.

Data acquisition is described in the following topics:v “Retrieving alarms” on page 4v “Status checking” on page 4v “Timeout” on page 4v “Backoff strategy” on page 4v “Filtering alarms” on page 5v “Event synchronization” on page 5

IBM Tivoli Netcool/OMNIbus Probe for Huawei N2000 (CORBA) 3

v “Command line interface” on page 6v “Peer-to-peer failover functionality” on page 7v “Running multiple probes” on page 8

Retrieving alarmsThe probe can retrieve alarms by calling the pullNewAlarms() method or by usingthe CORBA notification service.

Note: IBM recommends that you use the pullNewAlarms() method to retrieve data.

To make the probe use the pullNewAlarms() method, specify a value of false forthe UseNotificationService property. You must also specify values for thefollowing properties:v PullInterval - specifies the frequency with which the probe calls the method.v AlarmBatchSize - specifies how many alarms the probe retrieves each time the

method is called.

To make the probe use the CORBA notification service, specify a value of true forthe UseNotificationService property.

Status checkingThe probe checks that the Huawei N2000 server is running by sending a pingcommand every 60 seconds.

You can use the Agentheartbeat property to change the ping frequency.

TimeoutThe probe has a timeout facility that allows it to disconnect from the system ifthere has been no activity for a predefined amount of time.

You can use the Timeout property to specify how long the probe waits beforedisconnecting from the system.

Backoff strategyIf the Retry property is set to true, and the probe fails to establish a connection orloses an existing connection to the device, it reverts to a backoff strategy. The probetries to reestablish a connection after one second, two seconds, then four seconds,and so on, up to a maximum of 4096 seconds. Once the connection is made to theCORBA interface, the probe tries to log in to the device. If the probe fails to log in,it shuts down and tries to connect again. The backoff strategy remains in placeuntil a successful login occurs.


Filtering alarmsYou can limit the types of alarms the probe retrieves using the filtering properties.

The filtering properties allow you to exclude alarms according to their severity. Forexample, to exclude alarms of severity Indeterminate, set theExcludeSeverityIndeterminate property to true.

The following filtering properties are available:

Table 4. Filtering properties

Property Alarm Severity

ExcludeSeverityCleared Cleared

ExcludeSeverityCritical Critical

ExcludeSeverityIndeterminate Indeterminate

ExcludeSeverityMajor Major

ExcludeSeverityMinor Minor

ExcludeSeverityWarning Warning

Note: By default, the probe retrieves alarms of all severities.

Event synchronizationThe probe supports event synchronization between the Huawei N2000 system andthe ObjectServer.

When the probe restarts and requests a full resynchronization, the Huawei N2000does not send any cleared alarms. The ObjectServer will still show those alarms inits event list.

To synchronize the ObjectServer with the Huawei N2000 so that the ObjectServershows only uncleared events, set the Resynch and EventSynchronization propertiesto true. After the resynchronization is complete, the events that did not come fromthe Huawei N2000 through resynchronization (those that have been cleared) willbe removed from the ObjectServer.

Note: Event synchronization only works for resynchronization events. It does notaffect any new notification alarms. The ObjectServer will continue to receive allnotifications sent by the Huawei N2000, without regard to the state of the alarms.

Before running the probe for event synchronization, change the followingproperties in the EventSynch_N2000.sh file, located in the $OMNIHOME/probes/directory:Server="NCOMS" (ObjectServer Name)User="root" (User name for ObjectServer)Password="" (Password)


Command line interfaceThe probe has a command line interface (CLI) that you can use to performcommands using the probe, for example, to acknowledge or clear alarms in theCORBA interface.

To use the CLI, you must use the CommandPort property in the properties file tospecify a port through which commands will be sent. When you want to issuecommands, use Telnet to connect through this port.

Note: The probe can only use Telnet to connect to destination systems that haveenabled the Telnet.

The following table describes the commands that you can use with the commandline interface.

Table 5. CLI commands

Command Description

acknowledge_alarm Use this command to acknowledge one or morealarms in the CORBA interface.

This command takes as a parameter thenotification IDs of the alarms beingacknowledged. The syntax for the command is:

acknowledge_alarm Notification_Id1,Notification_Id2, ... Notification_Idn

clear_alarm Use this command to clear one or more alarms inthe CORBA interface.

This command takes as a parameter thenotification IDs of the alarms being cleared. Thesyntax for the command is:

clear_alarm Notification_Id1,Notification_Id2, ... Notification_Idn

help Use this command to display online help aboutthe CLI.

quit Use this command to close the connection to theprobe.

version Use this command to display the version of theprobe.

Note: Because the CLI is based upon Telnet connections, you can connect to theprobe from anywhere. This means that simple scripts can be set up to allow usersto acknowledge selected events from the Netcool/OMNIbus event list.


Peer-to-peer failover functionalityThe probe supports failover configurations where two probes run simultaneously.One probe acts as the master probe, sending events to the ObjectServer; the otheracts as the slave probe on standby. If the master probe fails, the slave probeactivates.

While the slave probe receives heartbeats from the master probe, it does notforward events to the ObjectServer. If the master shuts down, the slave probe stopsreceiving heartbeats from the master and any events it receives thereafter areforwarded to the ObjectServer on behalf of the master probe. When the master isrunning again, the slave continues to receive events, but no longer sends them tothe ObjectServer.

Example property file settings for peer-to-peer failover

You set the peer-to-peer failover mode in the properties files of the master andslave probes. The settings differ for a master probe and slave probe.

Note: In the examples, make sure to use the full path for the property value. Inother words replace $OMNIHOME with the full path. For example:/opt/IBM/tivoli/netcool.

The following example shows the peer-to-peer settings from the properties file of amaster probe:Server : "NCOMS"RulesFile : "master_rules_file"MessageLog : "master_log_file"PeerHost : "slave_hostname"PeerPort : 5555 # [communication port between master and slave probe]Mode : "master"PidFile : "$OMNIHOME/var/opc_ua"

The following example shows the peer-to-peer settings from the properties file ofthe corresponding slave probe:Server : "NCOMS"RulesFile : "slave_rules_file"MessageLog : "slave_log_file"PeerHost : "master_hostname"PeerPort : 5555 # [communication port between master and slave probe]Mode : "slave"PidFile : "$OMNIHOME/var/opc_ua2"


Running multiple probesYou can run multiple instances of the probe.

For each running instance, specify a different port to which the server listens usingthe ORBLocalPort property.

Running multiple probes in a failover configuration

If you have implemented a peer-to-peer failover configuration, both the masterprobe and the slave probe have their own Object Request Broker (ORB) local port.

Where you are running this configuration in conjunction with a firewall, add thereceiving port of each probe to the firewall rules. The direction of the connection isfrom the target system to the master or slave probe.

You set the peer-to-peer failover mode in the properties files of the master andslave probes.

Include the following peer-to-peer settings in the master's probe properties file:PeerHost : "slave_hostname"PeerPort : 5555 # [communication port between master and slave probes]

Include the following peer-to-peer settings in the slave's probe properties file:PeerHost : "master_hostname"PeerPort : 5555 # [communication port between master and slave probes]

Properties and command line optionsYou use properties to specify how the probe interacts with the device. You canoverride the default values by using the properties file or the command lineoptions.

The following table describes the properties and command line options specific tothis probe. For more information about generic Netcool/OMNIbus properties andcommand line options, see the IBM Tivoli Netcool/OMNIbus Probe and GatewayGuide.
