Table 1. Files: Summary statistics -
requests information
| DFHSTUP name |
Description |
| File name |
is the name you specified in:
- The DEFINE FILE command of resource definition online
- (for BDAM files only) The TYPE=FILE, FILE operand of the DFHFCT
macro.
|
| Get requests |
is the total number of GET requests issued against
this file.
|
| Get upd requests |
is the total number of GET UPDATE requests issued
against this file.
|
| Browse requests |
is the total number of GETNEXT and GETPREV requests
issued against this file.
|
| Update requests |
is the total number of PUT UPDATE requests issued
against this file.
|
| Add requests |
is the total number of PUT requests issued against
this file.
|
| Delete requests |
is the total number of DELETE requests issued
against this file.
|
| Brws upd requests |
is the total number of READNEXT UPDATE and READPREV
UPDATE requests issued against this file (RLS only).
|
| VSAM EXCP request: Data |
A value is printed if the file has been opened
and used as a VSAM KSDS during the CICS® run.
See notes 1, 2 and 3.
|
| VSAM EXCP request: Index |
See notes 1, 2 and 3.
|
| VSAM EXCP request: RLS req timeouts |
is the total number of RLS requests made to this
file that were not serviced in the specified time limit, and therefore
the requests were terminated.
|
Notes: The “VSAM EXCP requests” fields indicate the number of
I/O operations on the file for data and index records respectively.
Also, note the following points:
- The values printed for both items relate to the file.
If dynamic allocation has been used to change the physical data sets
associated with a file, the value shown is an accumulation for all
the data sets.
- Take care when using these values for files
participating in data set name sharing, because VSAM maintains only
one count of EXCPs for all access method control blocks (ACBs) thus
connected. In this situation, the value reported against each file
represents the total accesses for all sharing ACBs during the period
for which the file was open. Therefore, if all files in the data set
name sharing group were open for the same period, each file would
have the same EXCP values reported against it, which would be the
total for all the files in the group. When the count of EXCPs rises
above x'80000000', the count is no longer reliable, and you should
consider redefining the file.
- For RLS, this value is a count of the number of calls
to the system buffer manager. It includes calls that result in either
a coupling facility cache access or an I/O.
- The EXCP count for RLS files is the count of all EXCPs for all tasks accessing the RLS file within that CICS region. It should be noted as stated in note 2, EXCP counts are stored in the file's corresponding ACB within that CICS region.
