Testing the System with UETP |
|
|
| |
To start UETP, enter the following command and press Return:
UETP displays the following prompt:$@UETP
Run "ALL" UETP phases or a "SUBSET" [ALL]?Throughout the startup dialog, brackets indicate the default value, which you can choose by pressing Return.
When running UETP for the first time, it is recommended that you choose the default value (ALL) and run all the phases. If you choose ALL, UETP displays three more questions, which are described in Single Run Versus Multiple Passes through Report Formats. If you want to run all the test phases, skip the next section.
Running a Subset of Phases ![]()
You can run a single phase by entering SUBSET or S in response
to the following prompt:
Run "ALL" UETP phases or a "SUBSET" [ALL]?If you enter S or SUBSET, UETP prompts you for the phase you want to run as follows:
You can choose one or more of the following phases:
DEVICE, LOAD, DECNET, CLUSTER
Phases(s): There is no default; enter one or more phase names from the
list. Separate
two or more phases with spaces or commas. If your choice includes the LOAD phase, UETP displays three prompts:
How many passes of UETP do you wish to run [1]? How many simulated user loads do you want [n]? Do you want Long or Short report format [Long]?If you exclude the LOAD phase from your list of choices, UETP responds with only two prompts: the first and the third.
The next three sections discuss how you can respond to these questions. After you have answered the questions, the phase you have selected runs to completion.
Single Run Versus
Multiple Passes ![]()
If you
specified the default ALL or a subset of phases at the last prompt,
UETP displays the following message:
How many passes of UETP do you wish to run [1]?You can repeat the test run as many times as you want. If you enter 1 in response to the prompt (or press Return for the default), UETP stops after completing a single run. If you specify a number greater than 1, UETP restarts itself until it completes the specified number of passes.
You can run UETP once to check that the system is working, or many times to evaluate the system's response to continuous use. For example, a service technician who is interested only in verifying that a newly installed system works might run UETP once or twice. A manufacturing technician might let the system run for several hours as part of the system integration and test.
When you specify multiple UETP runs, you can request a short console log. (See Report Formats.) Ensure that all line printers and hardcopy terminals have enough paper because each run requires two pages.
Defining User Load for Load Test ![]()
After
you specify the number of passes, UETP prompts you as follows:
How many simulated user loads do you want [n]?
| UETP displays this prompt only if you choose to run the LOAD phase, either implicitly (by running all phases) or explicitly (by running a subset and specifying the LOAD phase). |
Although the given default value is the best choice, you can increase or decrease the user load by entering your own response to the prompt. However, be aware that an increase can cause the test to fail because of insufficient resources.
If you want to see UETP display the user-load equation as it runs, see Interpreting UETP Output.
Report Formats ![]()
The following prompt allows you to choose between long or
short report formats:
Do you want Long or Short report format [Long]?
Long Report Format ![]()
If you choose the long report format (the default), UETP sends the
following information to the console terminal:
UETP records all its output in the UETP.LOG file, regardless of your response to this question.
In many cases, it might not be convenient to have UETP write the bulk of its output to the terminal. For example, if you run UETP from a hardcopy terminal, the output printing can slow the progress of the tests. This delay might not be a problem if you have requested only one run; however, you might prefer to use the short format if you intend to run multiple passes of UETP from a hardcopy terminal.
Short Report Format ![]()
If you request the short format, UETP displays status information
at the console, such as error messages and notifications of the
beginning and end of each phase. This information enables you to
determine whether UETP is proceeding normally. If the short console
log indicates a problem, you can look at the file UETP.LOG for further
information. UETP.LOG contains all the output generated by the various
phases, as well as the status information displayed at the console.
After you choose the report format, UETP initiates its sequence of tests and runs to completion. If UETP does not complete successfully, refer to Troubleshooting: An Overview for troubleshooting information.
