Marking a Data Item as Unreferenced: Summary z/OS MVS Programming: Sysplex Services Guide SA23-1400-00 |
|
You use the RESET_REFBIT request to mark as unreferenced specified
data items.
If time-out criteria for the coupling facility are exceeded, the RESET_REFBIT request can complete prematurely. When a request completes prematurely, the system returns a token in the CAARESTOKEN field of the answer area. You can use this token to restart the request from the point at which it completed prematurely. To restart a request, first process the data based on the count information that the RESET_REFBIT returns in the ANSAREA. After processing the data, code the IXLCACHE REQUEST=RESET_REFBIT request as you previously coded it with the exception of the RESTOKEN keyword. The RESTOKEN keyword must specify the token that the system returned. There are other keywords that are required and some that are optional.
For a description of keywords that are applicable to all IXLCACHE
requests, see:
