Changing OLDS characteristics
Before you scratch and reallocate an OLDS that has been archived, you must delete the log control record in the DBRC RECON data set for this OLDS by using the DBRC DELETE.LOG OLDS(ddname) SSID (name) command.
You must delete the log control record for an OLDS that has been scratched and reallocated because the log control record only indicates that the OLDS has been archived. If you need this OLDS for IMS restart or batch backout, DBRC indicates to IMS to use this OLDS instead of the SLDS created by the archive job.
