<p class="MsoNormal"><span style="font-size:11.0pt"> Hello slony folks,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> I think this should be familiar territory for some: the doc has this example for performing controlled switchover.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">A small slonik script executes the following commands:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">lock set (id = 1, origin = 1);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">wait for event (origin = 1, confirmed = 2);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">move set (id = 1, old origin = 1, new origin = 2);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">wait for event (origin = 1, confirmed = 2, wait on=1);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> It’s been noted that the first wait op needs a “wait on=1” arg.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> Questions: does it matter which node this script is run on?
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> Is it also helpful to add waits with “wait on=2”? Or is it guaranteed (100% no timing issues) that waiting on the old origin node 1 insures that node 2 is ready to go as soon as the above-listed
waits finish?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> Thanks in advance,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
