If a VSAM sphere updated by CICS® is damaged and unusable, you can use CICSVR to re-create the VSAM sphere.
CICSVR:
You can set up a periodic automatic invocation of CICSVR SCAN, which keeps track of all the CICS forward recovery logs.
When the forward recovery run is complete, CICSVR has re-created the updated data.
For more information about the CICSVR functions, see the CICS VSAM Recovery MVS/ESA User’s Guide and Reference.
You can also use CICSVR to:
CICSVR lets you manage this RCDS information using the dialog interface.
You can use the dialog interface to remove information you no longer need about:
You can set an automatic function to delete and uncatalog logs after a specified time, and you can use CICSVR to delete parts of an MVS log stream. For added security, CICSVR maintains three copies of the RCDS.
Using CICSVR with DFSMShsm ensures that you have all information about backups. You need not keep a separate record of backups or logs for each data set.
For more information about the CICSVR archive utility and the MVS log stream copy utility, see the IBM® CICS VSAM Recovery MVS/ESA Implementation Guide.
To recover your VSAM data, start the CICSVR dialog interface. Select the data sets you want to work with, and then select "Complete recovery" from the main panel (see Running CICSVR). CICSVR guides you through the creation of your recovery job. An extensive help function ensures that you can always find out what to do next.
Use default values stored by CICSVR on previous runs, or use your own values. You decide which values to save for next time. You can browse, save, and, if necessary, edit the JCL before you submit it.
You need not withdraw services and close CICS regions to protect your data. You can maintain 24-hour availability of your data and ensure its integrity with CICSVR.
With BWO and the concurrent copy function, you can back up data while the data sets are open and being updated. CICSVR can recover using BWO copies, ensuring that the data is protected from loss at all times. If the data should become damaged or inaccessible, CICSVR can use BWO backups to retrieve the data. Because you can make backups without interrupting your CICS regions, you can make them more often.
