In IBM® Tivoli®Netcool®/OMNIbus, when an event expires that event is acknowledged in IBM Tivoli® Monitoring (ITM), but if the problem still exists, ITM re-opens the situation and an update event will be sent from ITM to Netcool/OMNIbus. This update event does not contain all the necessary attributes, causing partial event data to be displayed in Netcool/OMNIbus. This utility helps resolve this situation.
In IBM® Tivoli®Netcool®/OMNIbus, when an event expires that event is acknowledged in IBM Tivoli® Monitoring (ITM), but if the problem still exists, ITM re-opens the situation and an update event will be sent from ITM to Netcool/OMNIbus. This update event does not contain all the necessary attributes, causing partial event data to be displayed in Netcool/OMNIbus.
To address this concern, this utility creates a table, to cache event data, in the Netcool/OMNIbus ObjectServer 'custom' database. It also adds triggers to the status and itm events tables in the ObjectServer alerts database. These triggers will cache expired events. When those situations either automatically re-opened or are manually opened in ITM, the event synchronization brings the events data to Netcool/OMNIbus. The triggers again take control and restore the missing attributes using the cached event data. This stores full event data in the alerts.status table once again. Besides, the caching and restoring of events the automation logic also purges the cache on a regular interval, and can log the change information to an output file.
Files in this package:
