            <title>[DOCS-11255] Document that 3.6 implicit sessions may cause noTimeout cursors to close while in use.</title>

                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;The following code will work on MongoDB 3.4. The cursor is created with the no timeout option and is left open on the server until the application closes it.&lt;/p&gt;

&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;MongoDB 3.6 drivers will add an implicit session to every command. The find command will use a new session and again create a cursor with the no timeout option. However, that session will timeout after 30 minutes of inactivity and the cursor will be closed.&lt;/p&gt;

&lt;p&gt;Users that need the cursor timeout to exceed the session timeout will need to write code to periodically refresh the session. This will prevent the session (and cursor) from timing out:&lt;/p&gt;

&lt;p&gt;I don&apos;t think this change has been documented yet. CC &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=alyson.cabral&quot; class=&quot;user-hover&quot; rel=&quot;alyson.cabral&quot;&gt;alyson.cabral&lt;/a&gt;&lt;/p&gt;

&lt;h2&gt;&lt;a name=&quot;Scope&quot;&gt;&lt;/a&gt;Scope&lt;/h2&gt;

&lt;ul&gt;
	&lt;li&gt;Update &lt;a href=&quot;https://docs.mongodb.com/manual/reference/method/cursor.noCursorTimeout/index.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;noCursorTimeout&lt;/tt&gt;&lt;/a&gt; to include the session refresh requirements (e.g. implicit 30 minute max)&lt;/li&gt;
	&lt;li&gt;Update &lt;a href=&quot;https://docs.mongodb.com/manual/reference/method/Mongo.startSession/#Mongo.startSession&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;Mongo.startSession()&lt;/tt&gt;&lt;/a&gt; and &lt;a href=&quot;https://docs.mongodb.com/manual/reference/command/startSession/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;startSession&lt;/tt&gt;&lt;/a&gt; to include the session timeout limit (30 minutes) + refreshSession&lt;/li&gt;
	&lt;li&gt;Add the &lt;tt&gt;Session.refreshSession()&lt;/tt&gt; shell method if it exists. Otherwise point to &lt;a href=&quot;https://docs.mongodb.com/manual/reference/command/refreshSessions/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;refreshSession&lt;/tt&gt;&lt;/a&gt; dbcommand&lt;/li&gt;
	&lt;li&gt;Update find/agg behavior sections to call out 30 minute session timeout behavior&lt;/li&gt;
	&lt;li&gt;Add to Cursor.tailable, tailable pages&lt;/li&gt;

                            <comment id="2411034" author="ravind.kumar" created="Fri, 6 Sep 2019 17:47:17 +0000"  >&lt;p&gt;As a small update, i&apos;m currently poking around this and am considering two stages to this fixup:&lt;/p&gt;

&lt;p&gt;1) note (for all cursor-related docs) that the sessionTImeout overrides noCursorTimeout, and to use refreshSessions + explicit sessions for all ops to prevent session timeout.&lt;/p&gt;

&lt;p&gt;2) for ops issued outside of a session, a combination of currentOp ( to retrieve the lsid) and refreshsessions should work instead. &lt;/p&gt;

&lt;p&gt;1 I can finish must faster than 2, which will require some testing to confirm my thoughts. &lt;/p&gt;</comment>
                            <comment id="2408864" author="ravind.kumar" created="Thu, 5 Sep 2019 14:21:14 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=alyson.cabral&quot; class=&quot;user-hover&quot; rel=&quot;alyson.cabral&quot;&gt;alyson.cabral&lt;/a&gt; am I right in thinking that, for 3.6+, this means that any op that returns a cursor (find/agg in particular) can timeout after 30 minutes of session inactivity (no auth reresh) ?&lt;/p&gt;

&lt;p&gt;e.g. a user starts an agg op that takes more than 30 minutes to return, session timeout kills the cursor? &lt;/p&gt;

&lt;p&gt;If so then I think I&apos;ll have to call out this behavior in quite a few places. I&apos;d also like to see if we can provide better guidance than &apos;run &lt;tt&gt;refreshSessions&lt;/tt&gt; periodically for all open sessions&apos;. &lt;/p&gt;</comment>

You need to run a command that requires auth such as &lt;a href=&quot;https://docs.mongodb.com/manual/reference/command/refreshSessions/#dbcmd.refreshSessions&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;refreshSessions&lt;/a&gt;.&lt;/p&gt;</comment>
