<h3>
<b><font size=+2>Standard Compatibility Test</font></b></h3>
&nbsp;
<p>&nbsp;
<br>&nbsp;
<br>&nbsp;
<p>Compatibility is an important aspect of the <a href="/project/gridengine/license.html">License</a>
under which Grid Engine source code is made available. In this context,
cross compatibility may have to be certified between a version of the Grid
Engine software which you have enhanced and a version declared as one of
Grid Engine's <font color="#990000">Reference Builds</font> from which
your modification deviates. Note, that over time there can be multiple
Reference Builds representing different stable software release levels.
You might intend to test compatibility with one or with multiple of those
Reference Builds. A list of the currently available Reference Builds with
all pertinent information can be found <a href="/project/gridengine/standards.html">here</a>.
<p>The following describes how to test compatibility between two builds.
You will need to create a <a href="../source/dist/dist.html">binary distribution
package</a>&nbsp; for both builds before you start with the compatibility
checking process. You will also have to make all preparations to be able
to run the Grid Engine <a href="../testsuite/testsuite.html">Testsuite</a>.
You will have to use the Testsuite level as defined in the <a href="/project/gridengine/standards.html">Reference
Build definition</a>.
<p>The compatibility test consist of a preparation step, a validation run
of the Standard Version and multiple compatibility checks. Your changed
version has to pass all tests without error and has to deliver the same
results as the validation run to be considered compatible.

<br>Release Notes:
<p>&nbsp;<a href="#notes_5_3">Version 5.3</a>
<p>
<hr WIDTH="100%">
<h3>
Preparation:</h3>

<ul>
<li>
Set up a testsuite cluster with more than one host</li>
</ul>

<blockquote>The <a href="../testsuite/testsuite.html">Testsuite</a> documentation
is describing how this can be done. Use the <b><i>Reference Build</i></b>
to which you want to test compatibility and run:</blockquote>

<blockquote>
<blockquote><tt>expect check.exp install</tt></blockquote>
The testsuite will generate a default setup file "defaults.sav" in the
testsuite directory. After that the testsuite will start the vi command
in order that the user can edit the testsuite settings. You will be asked
on which hosts you want to install a testsuite cluster and you will have
to use at least 2 for the purpose of the compatibility test. Please enable
the error mails by providing your e-mail address when setting up the testsuite.
The testsuite will report errors by e-mail.</blockquote>

<h3>
Validation:</h3>

<ul>
<li>
Run testsuite on Reference Build</li>

<br>&nbsp;
<p>&nbsp;
<p>Run the testsuite with following command (<a href="#testsuite start output">Testsuite
start output</a>):
<br>&nbsp;
<ul><tt>expect check.exp all 2 category COMPATIBILITY</tt></ul>

<p><br>Do not remove the test results of the validation run. Every testsuite
run will manipulate the results directory, so copy your validation results
before running another test. You will need to compare your validation run
results with the subsequent compatibility runs. No errors must occur during
the validation run. If you encounter errors then this might be due to network
setup problems in your cluster or similar issues. Fix those first before
you proceed. Report your problem if it persists. You cannot test compatibility
with a validation run with errors.</ul>

<h3>
Check 1: Qmaster compatibility</h3>

<ul>(If you are absolutely sure that your modification did not change sge_qmaster
you may skip this step, but be aware that changes in some libraries, like
for instance the scheduler library, may also modify sge_qmaster. Carry
out the test if you are not 100% sure.)
<br>&nbsp;
<li>
Shutdown the system</li>

<br>&nbsp;
<p>&nbsp;
<p>Use the testsuite to shutdown the cluster:
<br>&nbsp;
<ul><tt>expect check.exp kill</tt></ul>
</ul>

<ul>
<li>
Exchange the sge_qmaster binary with the one from your modified build</li>
</ul>

<ul>
<li>
Run the testsuite again:</li>

<br>&nbsp;
<ul><tt>expect check.exp all 2 category COMPATIBILITY</tt></ul>

<li>
Compare results with validation run</li>

<br>&nbsp;
<ul>&nbsp;Stop if the results are not equal.</ul>

<li>
Shutdown the system</li>

<br>&nbsp;
<p>&nbsp;
<p>Use the testsuite to shutdown the cluster:
<br>&nbsp;
<ul><tt>expect check.exp kill</tt></ul>

<li>
Re-Exchange the sge_qmaster binary with the one from the Reference Build</li>
</ul>

<h3>
Check 2: Scheduler compatibility</h3>

<ul>(If you are absolutely sure that your modification did not change sge_schedd
you may skip this step, but be aware that changes in some libraries, like
for instance the GDI library, may also modify sge_schedd. Carry out the
test if you are not 100% sure.)</ul>

<ul>
<li>
Exchange the sge_schedd binary with the one from your modified build</li>
</ul>

<ul>
<li>
Run the testsuite again:</li>

<br>&nbsp;
<ul><tt>expect check.exp all 2 category COMPATIBILITY</tt></ul>

<li>
Compare results with validation run</li>

<br>&nbsp;
<ul>Stop if the results are not equal.</ul>

<li>
Shutdown the system</li>

<br>&nbsp;
<p>&nbsp;
<p>Use the testsuite to shutdown the cluster:
<br>&nbsp;
<ul><tt>expect check.exp kill</tt></ul>

<li>
Re-Exchange the sge_schedd binary with the one from the Reference Build</li>
</ul>

<h3>
Check 3: Commd compatibility</h3>

<blockquote>(If you are absolutely sure that your modification did not
change sge_commd you may skip this step, but be aware that changes in some
libraries, like for instance the zlib, may also modify the sge_commd. Carry
out the test if you are not 100% sure.)</blockquote>

<ul>
<li>
Exchange all sge_commd binaries with the ones from your modified build</li>
</ul>

<ul>
<li>
Run the testsuite again:</li>

<br>&nbsp;
<p>&nbsp;
<br>&nbsp;
<br>&nbsp;
<ul><tt>expect check.exp all 2 category COMPATIBILITY</tt></ul>

<li>
Compare results with validation run</li>

<ul>&nbsp;
<br>Stop if the results are not equal.</ul>

<li>
Shutdown the system</li>

<br>&nbsp;
<p>&nbsp;
<p>Use the testsuite to shutdown the cluster:
<br>&nbsp;
<ul><tt>expect check.exp kill</tt></ul>

<li>
Re-Exchange the sge_commd binaries with the ones from the Reference Build</li>
</ul>

<h3>
Check 4: Client compatibility</h3>

<blockquote>(If you are absolutely sure that your modification did not
change any Grid Engine client binary you may skip this step, but be aware
that changes in some libraries, like the GDI library,&nbsp; may also modify
the client binaries. Carry out the test if you are not 100% sure.)</blockquote>

<ul>
<li>
Exchange all client binaries with the new ones</li>
</ul>

<ul>
<li>
Run the testsuite again:</li>

<br>&nbsp;
<ul><tt>expect check.exp all 2 category COMPATIBILITY</tt></ul>

<li>
Compare results with validation run</li>

<ul>&nbsp;
<br>Stop if the results are not equal.</ul>
</ul>

<h3>
Check 5: General compatibility</h3>

<ul>
<li>
Shutdown the system</li>

<br>&nbsp;
<p>&nbsp;
<p>Use the testsuite to shutdown the cluster:
<br>&nbsp;
<ul><tt>expect check.exp kill</tt></ul>

<li>
Set up a testsuite cluster with more than one host using the modified build</li>

<br>&nbsp;
<p>&nbsp;
<p>The <a href="../testsuite/testsuite.html">Testsuite</a> documentation
is describing how this can be done. Use the <b><i>modified build</i></b>.
<br>&nbsp;
<ul>&nbsp;expect check.exp install</ul>

<p><br>The testsuite will generate a default setup file "defaults.sav"
in the testsuite directory. After that the testsuite will start the vi
command in order that the user can edit the testsuite settings. You will
be asked on which hosts you want to install a testsuite cluster and you
will have to use at least 2 for the purpose of the compatibility test.
<p>Run the testsuite with following command on your modified build:
<br>&nbsp;
<ul>
<li>
<tt>expect check.exp all 2 category COMPATIBILITY</tt></li>
</ul>

<li>
Compare results with validation run</li>

<ul>&nbsp;</ul>
Stop if the results are not equal.
