Re: AS400 Transaction in performance tools

Thanks Vern! I also found this on the work management redbook.

Transaction - A transaction is a logical unit of work on the iSeries
system. It is commonly referred to in relation to database operations.

From the v5r4 Work Management guide - note the end of the 2nd
paragraph, which mentions transaction count - I think transactions are
basically hitting the Enter key. And maybe function keys that cause the
interactive session to do some work.

Total Response Time and Number of Transactions: Following the times and
dates are the total response time and the number of transactions. The
total response time is in seconds and contains the accumulated value of
all the intervals the job was processing between pressing the Enter key
at the workstation and when the next display is shown. This information
is similar to that shown on the Work with Active Job (WRKACTJOB)
display. This field is only meaningful for interactive jobs.

It is also possible in the case of a system failure or abnormal job end
that the last transaction will not be included in the total. The job end
code in this case would be a 40 or greater. The transaction count is
also only meaningful for interactive jobs other than the console job and
is the number of response time intervals counted by the system during
the job.


OK - here it is, as I search for "transaction" further into the manual -

Note: A transaction is defined as any operator interaction, like
scrolling, pressing enter, pressing function keys, and so on. Typing at
the workstation without pressing enter is not considered a transaction.
If a job at the workstation does not meet the inactive criteria, the job
is considered active.

Hi Guys,

I'm compiling an AS400 performance report for management and I've just been
asked a question which I can't provide a basic answer:

What is an AS400 transaction?

The best answer I can come up with so far is saying any database read and
write on the iSeries is a transaction.

What's the best way to explain an AS400 transaction?

Thanks!
