Creating and editing a dataset

A dataset in BMC CMDB is used to capture data from different data sources.

To create a dataset

1. Open the Datasources page.
   Dashboard > Manage Datasources
2. Click Add Dataset.
   

3. Specify the following fields:

   Name	Type a unique name. The name cannot contain any characters that are not allowed in file names for the operating system of your server. For example, on a Windows server, your job name cannot contain the following characters: \ / : * ? " < > |
   Dataset ID	Type a unique ID string for the dataset. The dataset ID cannot contain a slash (/) , semicolon (;) , or comma (,). If you do not provide an ID, the system generates a GUID to use for this ID. The name and dataset ID cannot be changed from this page after you have created the dataset.
   Accessibility	Select whether the instances can be created, modified, and deleted in the dataset. Writable — Any process can write to the dataset. Read Only — No process can write to the dataset. Data can only be viewed.
   Dataset Type	Select the Regular or Overlay radio buttons. For information about overlay datasets, see Overlay datasets.
   Source Dataset ID (available only if you select Overlay in the Dataset Type list)	Specify the existing regular dataset upon which your new dataset will be overlaid.
   Permissions	Select the groups and roles which will have permissions to this dataset in the Groups and Roles list.

4. Click Save.
   The dataset appears in the Datasets list of the Datasources page. 

To edit a dataset

You cannot edit dataset properties from the CMDB Portal except for the permissions. You must use the BMC Dataset Remedy AR System form to edit a dataset.

1. Open the BMC.CORE.CONFIG:BMC_Dataset form.
   For example:
   http://<midTier:port>/arsys/forms/<ARServer/>BMC.CORE.CONFIG:BMC_Dataset
   http://vw-bsm-idd-midtier:8080/arsys/forms/idd-arserver/BMC.CORE.CONFIG:BMC_Dataset
   
   The form opens in search mode.
2. Enter search criteria to find the dataset you want to edit and click Search.
3. Edit the properties and click Save.
