Automation can be done in object server which facilitates the user to detect changes in the object server and we generate responses to these changes. This help the admin that he will get to know about the changes done in the object server without taking any action.

• Probe is a java written code which works as a agent it connect to the source where there is possibility of generating an event.
• It detects it, collects it and forward the data to object server as events where it is displayed in event list.
• Probes are event source specific.
• Rules for the event detection and collection are define in the rules file.
• The event collected are updated in the table alerts.status.

• Gateways are the intermediaries between the object server and the third party application such as databases for the exchange of events.
• Gateways can also be used to replicate events and to maintain the backup of object server.

• Import and export Tivoli Netcool/OMNIbus ObjectServer configurations to deploy duplicate Tivoli Netcool/OMNIbus systems in your network.
• Extract a subset of configuration items from Tivoli Netcool / OMNIbus Object Servers and import them into other ObjectServers.
• Save Tivoli Netcool/OMNIbus ObjectServer configuration data for backup purposes.

The components are as follows:
• Conductor
• Event List
• Filter Builder
• View Builder

• Ans. Netcool is a SLM tool which is used to monitor the real time networks, flow of data from one tool to another.
• It provides the consolidated view of the events generated on one screen collected from another tool
• Netcool can gather various informations like server down alerts, CPU utilization high alerts, memory alerts, disk space, mount point full related alerts etc. etc.

• The ObjectServer
• Probes
• Gateways
• Desktop Tools
• Administration Tools

• The ObjectServer is the in-memory database server at the core of Tivoli Netcool/OMNIbus.
• Event information is forwarded to the ObjectServer from external programs such as probes and gateways.
• This information is stored and managed in database tables, and displayed in the event list.

• Single server can generate the alert repeatedly until the problem is not resolved related to that alert.
• So deduplication is used by object server in Netcool/Omnibus.
• This process makes sure to avoid the multiple entries generated in the Event List.
• Therefore repeated events are collected, identified and updated as a single event.
• This process reduces the size of data as well.

• For UNIX: From a command prompt, type: $NCHOME/omnibus/bin/nco &
• For Windows: From the Windows Start menu, click Netcool Conductor.
• Type your user name.
• Type your password
• The ObjectServer name defaults to NCOMS
• Click Ok.
