Configuring Data Archiving
This topic talks about the data archiving policy for Reconciliation Engine and Normalization Engine. In the event where various engines, especially the Normalization Engine and the Reconciliation Engine generate large number of records in the respective forms related to job run history, it is desirable that the history of records is retained that can be quickly accessed. With this implementation a Configuration Administrator or a Configuration Manager will not have to go back and look at data from an historical perspective on these forms, but can access the retained history whenever needed to investigate execution history and success.
When the Reconciliation Engine and the Normalization Engine runs, there are jobs that run and every time a job runs on a particular CI, there is an entry that is made to the job runs form.
- The Archive Manager runs once in 24 hours. This is configurable.
- For CMDB (Reconciliation Engine and Normalization Engine) job run history forms, the default age of data that will be archived is 90 days. This is configurable and can be modified from the AR Archive Manager Console.
Data Archiving Policy for Reconciliation Engine
The archiving policy of type Copy to an archive form and delete from source is defined for the Reconciliation Engine where all the records with last modified date earlier than 90 days are considered for archiving. The archived data is pushed to the RE:JobRuns_Archive form where it can be searched.
Data Archiving Policy for Normalization Engine
The archiving policy of type Copy to an archive form and delete from source is defined for the Normalization Engine where all the records with last modified date earlier than 90 days are considered for archiving. The archived data is pushed to the NE:JobRuns_Archive form where it can be searched. As an exception for Normalization Engine, the data for continuous jobs is not archived.
The RE:JobRuns and the RE:Job_Events forms are associated. When you archive the data from the RE:JobRuns form, the data in the RE:Job_Events form related to the JobRuns instance ID is also archived based on the defined association. For more information on Associations, see Associations Overview. For information on archiving, see Archiving data.
Viewing Archived records
You can view the archived records by opening the following forms in Midtier:
The following are the benefits of CMDB data Archiving feature:
- Reduces the size of production data sets
- Improves overall system performance (for example, searches run more quickly, because they look only at production data and not at archived data)
