Table 1. Files: Summary statistics - data table requests information
DFHSTUP name Description
File Name The name you specified in the DEFINE FILE command of resource definition online.
Table type This 1 byte field is set as follows:
  • C when a CICS® maintained table is closed.
  • P when a file that accessed a CICS maintained table is closed, but the table remains open because other files that are using the table are still open.
  • S when the source data set for a user maintained table is being closed.
  • U when a user maintained table is closed.
  • L when a locking model coupling facility data table is closed.
  • K when a contention model coupling facility data table is closed.
Successful reads The total number of reads from the data table.
Recs in table The number of reads where the record was not found in the data table, so CICS retrieved the record from the source file.
Adds from reads The total number of records placed in the table by the loading process, or as a result of API READ requests issued while loading was in progress.
Add requests The total number of attempts to add records to the table as a result of WRITE requests.
Adds rejected - exit The total number of records CICS attempted to add to the table that were rejected by the global user exit.
Adds rejected - table full The total number of records CICS attempted to add to the table but was could not because the table already contained the maximum number of records specified.
Rewrite requests The total number of attempts to update records in the table as a result of REWRITE requests.
Delete requests The total number of attempts to delete records from the table as a result of DELETE requests.
Highest table size The peak number of records present in the table.
Chng Resp/Lock Waits For a CFDT that uses the locking model, records are locked down when they are read for update. This count is the number of times it was necessary to wait for a record that was already locked.

For a CFDT that uses the contention model, records are not locked when they are read for update. If a subsequent rewrite or delete request finds that the record has already changed, a CHANGED response is returned. This count is the number of times that a CHANGED response was issued.
