Creating an IBM DFSMSdss backup profile
IMS Recovery Expert can make backups using DFSMSdss. You might want to use DFSMSdss profiles if your site does not have fast-replication hardware, or if your site's hardware does not support Snap or FlashCopy® but supports other fast-replication through DFSMSdss.
About this task
This type of backup profile supports DFSMSdss traditional copies and IBM®/STK SnapShot. IMS Recovery Expert can maintain up to 99 generations of DFSMSdss backups on disk.
For DFSMSdss backups, the target volumes must be online when profile setup is run and when the backup is taken. In addition, all target volumes must have their own unique volume serial.
Note: If fast-replication is not used, the backup process might be lengthy depending on the number
of volumes copied.
Procedure
- On the System Backup Profile Display panel
(BSY$BPRD),
specify C on the Cmd line
and press Enter.

specify information in the following fields:
- Creator
- This field is automatically populated with your user ID as the profile creator.
- Profile name
- Specify a name for the profile (up to 30 characters).
- Description
- (Optional) Specify a profile description.
- IMS SSID
- Specify the IMS system or group for the profile in this field. To view a list of systems and groups to choose from, specify ? in this field and press Enter. The SSID Selection panel is displayed. This panel lists available systems and groups and indicates whether they are active or inactive. Select a system or group by specifying S next to the SSID or group name, and then press Enter.
- Backup Method
- Specify L to select DFSMSdss backup.
- Source/Target Mapping
- Specify how source volumes are determined and mapped to the target
volumes. You can specify one of the following values in this field:
- Specify A to select Auto discover/pool mapping. If you specify this option, the source volumes are automatically discovered at run time and mapped to target volumes using a pool of target volumes (either units or SMS storage groups).
- Specify S to select Stogroup discover/pool mapping. If you specify this option, the source volumes are discovered using SMS storage groups that are specified for an IMS system. These source volumes are mapped to target volumes using a pool of target volumes (either units or SMS storage groups).
- Specify M to select Manual mapping. If you select this option, you can manually specify the source volumes and map them to target volumes.
- Update Option
- This option controls how other users can use your profile.
- Specify U to allow others to update the profile.
- Specify V to allow others to view but not update the profile.
- Specify N to prevent others from viewing or updating the profile.
- Press Enter.

- Backup Method
- The backup method used for this profile. This field contains L for DFSMSdss backup.
- Current generation
- When you first create a profile, this field will be set to 0. After the profile has been built and submitted, this field will contain the generation that is currently mirroring IMS.
- Setup Needed
- When you create a profile, this field will be set to Y. The profile setup process must be run the first time a profile is built and the resulting job submitted. When profile setup has been performed, this field will contain N when you update the profile. If you update a profile and change the volume configuration, number of generations, or backup scope, you must run the profile setup again and this field will be reset to Y.
- Specify information in the following fields:
- Backup Scope
- Specify if you want a full backup taken (both data and logs) or to back up data only. Note that if you specify data only and IMS Recovery Expert detects log data on the volumes during the backup, the backup will proceed without error only if all IMS log and data volumes have been included in the profile. In this case, the backup will be flagged as a mixed data backup and you will only be able to restore both the data and the logs.
- Backup Generations
- Specify the number of generations of backups you want to keep. Valid values are 1 to 99.
- Offload Options
- Specify Y in this field if you want to retain more backups than the number specified in the Backup Generations field. If you specify this option, IMS Recovery Expert will offload older backups to another device (such as tape or other volumes). When you initially select this option, the Offload Options panel will be displayed. If you edit the profile at a later time and you want to update the offload options, specify U in this field.
- Issue Log Suspend
- If all of the source and target volumes support a storage-based consistency function, then set this value to N. Set this value to Y if all of the source and target volumes do not support a storage-based consistency function. If all source and target volumes are FlashCopy capable, then IMS Recovery Expert stops all logging activity on the IMS system(s) while the backup is made when this value is set to Y. If any of the source or target volumes are not FlashCopy capable, then the backup can only be made if the IMS system(s) is not active.
- Validate IMS volumes
- If you specify Y in this field, each time the backup job is run, IMS Recovery Expert will determine what volumes the IMS environment is using and ensure the volumes are included in the backup. The profile setup process will always validate volumes, among other profile setup procedures.
- Enable DB Restore
- If you want to enable IMS Recovery Expert application or database-level recovery from backups created by this profile, specify Y in this field. During backup, IMS Recovery Expert saves information about database data sets that allows databases to be individually restored later.
- Issue NOTIFY.IC
- If you want to have a NOTIFY.IC done for each object when a backup
is created, specify Y in this field. The NOTIFY.IC
will be done for each recoverable object in the backup and allows
DBRC to be notified that a backup of the object was created. Note: Issue NOTIFY.IC is set to Y when a System Level Backup is created. IMS Recovery Expert will issue a NOTIFY.IC for each object in the System Level Backup with an invalid image copy data set name. If an image copy data set is needed, then the image copy data sets can be created by generating the build image copy JCL from System Level Backup. Refer to Creating image copies from System Level Backups for more information on generating the build image copy JCL.
- Select the source and target volumes for the specified IMS environment.
