Implementing Services › Back Up Service Definitions

Back Up Service Definitions

To assist you with the maintenance of your service definitions, you can create backup versions of your service image. By creating a backup version of your service image or definitions, you can perform the following:

• Update service definitions in any version of a service image
• Restore a service definition from a backup service image
• Merge two versions of a service image

To create a backup version of a service image

1. Enter /SADMIN.SI at the prompt.

   The service image list appears.

   Note: If you have not created a backup before, there is only one service image listed: $SERVICE 0001.The active service image can be $SERVICE 0001 only. $SERVICE 0001 cannot be deleted.

2. Enter C next to the service image you want to copy.

   The ServiceView : Service Image Definition panel appears.

3. Enter a new Database Version, Short Description, and (optionally) a Long Description.
4. Press F3 (File).

   A copy in progress panel opens while the copy occurs. The Service Image List appears with the backup version displayed in the list.

Update Service Definitions in a Backup Service Image

You can access a list of all the service definitions in any version of a service image. From this list you can update any service definitions contained in the service image.

To update a service definition in the $SERVICE 0002 backup image

1. Enter L (List Services) beside the $SERVICE 0002 service image in the Service Image List.

   The ServiceView : Service List panel appears showing the service definitions in that service image.

   Note: You can access the list of service definitions for another version of the service image by changing the version number on the Service Image List panel and pressing Enter.

2. Enter U beside the service definition that you want to update.

   The ServiceView : Panel Display List appears for that service definition.

3. Update the service definition, as required.
4. Press F3 (File) to save the changes.

   The ServiceView : Service List panel appears.

Restore a Service Definition from a Backup Service Image

If you have made changes to a service definition and you are having trouble with its implementation, you can restore it from a previous version of the definition.

To restore service definition SERV01 from $SERVICE 0002 service image to $SERVICE 0001

1. Enter C beside SERV01 in the ServiceView : Service List.

   The ServiceView : Service Image Definition panel appears.

2. Change the Database Version from 0002 to 0001 and press F3 (File).

   Because there is already a copy of the service in the target service image, the Confirm Copy Replace panel appears.

3. Press Enter to confirm the replace or F12 (Cancel) to cancel the request.

   The ServiceView : Service List panel appears.
