User response
The statistics are described in detail in the DFHNCS4D data area. The individual fields have the following meanings:
-
Response counts:
- Asynch
-
Number of requests for which completion was asynchronous.
- Unavail
-
Number of times requests were deferred because the structure was temporarily unavailable, for example because system-managed rebuild was in progress.
- Normal
-
Number of normal responses.
- Not fnd
-
The specified entry (table or item) was not found.
- Vers chk
-
A version check failed for an entry being updated. This occurs when a duplicate name is found while creating a new entry, or when an assign request finds the counter has reached its limit, or when a compare and swap type request (assign with increment, rewind or update) finds that the counter changed before the attempt to set the new value, in which case the request is retried until successful.
- List chk
-
A list authority comparison failed. This should only be possible during server initialization.
- Str full
-
The list structure became full.
- I/O err
-
Some other error code was returned by IXLLIST.
