All of the data set entries in the hiperbatch caching global table (GCT) have been filled. No additional data sets can be cached except retained Virtual Storage Access Method (VSAM) data sets in CREATE (LOAD) mode, and those only after a data set entry becomes available. Caching will continue for those data sets already opened and connected. Caching will also be done for new opens if the CGT already contains an entry for that data set.
To re-establish full hiperbatch caching capabilities, you must re-IPL the system.
You can change the size of the CGT to allow for more data set entries using the data lookaside facility (DLF) installation exit routine. The change would take effect after the next IPL.
