Use the ZOSTOUCH utility on a z/OS system where PowerExchange is installed to update the Last Referenced Date (LRD) of selected PowerExchange data sets.
If an incorrect management class was specified for PowerExchange data sets that the PowerExchange Listener uses, you can use ZOSTOUCH to update the LRD of the data sets instead of manually changing the data sets to use a correct management class.
ZOSTOUCH performs the following actions:
Processes each file DD in sequence until no more DDs are found.
Opens and closes the file, which causes the LRD to be set to the current date.
Reports file information from the IBM fldata() function to standard output, which you can view in SYSPRINT.
