		<summary type="html">&lt;p&gt;Created page with &amp;quot;&amp;#039;&amp;#039;&amp;#039;GLX_SHM_REG&amp;#039;&amp;#039;&amp;#039; is a &lt;a href=&quot;/System_Parameters&quot; title=&quot;System Parameters&quot;&gt;system parameter&lt;/a&gt; used on &lt;a href=&quot;/Alpha&quot; title=&quot;Alpha&quot;&gt;Alpha&lt;/a&gt; &lt;a href=&quot;/index.php?title=OpenVMS_Galaxy&amp;amp;action=edit&amp;amp;redlink=1&quot; class=&quot;new&quot; title=&quot;OpenVMS Galaxy (page does not exist)&quot;&gt;Galaxy&lt;/a&gt; systems only that specifies  the number of shared memory region struc...&amp;quot;&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;GLX_SHM_REG&amp;#039;&amp;#039;&amp;#039; is a [[System Parameters|system parameter]] used on [[Alpha]] [[OpenVMS Galaxy|Galaxy]] systems only that specifies  the number of shared memory region structures configured into the Galaxy Management Database (GMDB). If set to 0, the default number of shared memory regions are configured.&lt;br /&gt;
&lt;br /&gt;
If the condition value SS$_INSF_SHM_REG is returned for the $CRNMPSC_GDZRO_64 system service with the flag SEC$M_SHM_REG, the Galaxy shared memory code has run out of internal SHM_REG data structures. You need to increase the system parameter [[GLX_SHM_REG]] and reboot all Galaxy instances with this larger parameter value.&lt;br /&gt;
