From 5.2<\/span> and above, Zoom server can be configured to perform database checkpointing<\/span> only at scheduled automatic server restarts. Previously, every time Zoom server started, checkpointing would be performed. This checkpointing would take stock of all data operations executed on the Zoom server since the previous checkpoint, compacting the database in the process. However, this was inconvenient as the server became unavailable until checkpointing completed, especially at times when say, administrative setting changes require server restarts.<\/p>\n\n\n\n

For Zoom versions before 5.2<\/span>, checkpointing is enabled by default and is executed upon Zoom Server startup.<\/div>\n\n\n\n

With, Zoom 5.2<\/span> and above, if the Zoom server has been scheduled to restart automatically at a particular time and frequency, say daily at 1 AM, then checkpointing is performed only on those scheduled server restarts. On all other restarts, the server will not perform checkpointing.<\/p>\n\n\n\n

Automatic Checkpointing Service<\/h2>\n\n\n\n

The auto-restart can be configured using the Zoom Web Management Console<\/span>. Log into<\/strong> Web Management Console <\/span>as an admin. Go to<\/strong> Server Control Panel<\/span> under System <\/span>node in the Admin Menu<\/span> on the left. Click Automatic Server Restart Settings<\/span>.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

If Enable Auto-Restart Service<\/span> is checked, Zoom will follow the scheduled setup, such as every 7 days on Sunday midnight, to perform a server restart and a subsequent checkpoint. In order to do so, before every auto-restart, the <doCheckpoint><\/code> tag under <autorestartspec><\/code> in server.xml<\/span> is automatically modified to true<\/em> by the auto-restart service. Once the checkpoint is finished, the property is reset back to false<\/em> in server.xml<\/span> file.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
If auto-restart is disabled, checkpoint will be enabled for each restart. Administrators can override this by setting <doCheckpoint><\/code> tag as false<\/em> in server.xml<\/span> to ensure that the server restarts without checkpointing. However, after a successful startup, the server will revert to performing checkpointing on subsequent restarts. This is necessary as periodic checkpointing needs to be performed automatically.<\/div>\n\n\n\n

<\/a>Forced or Manual Checkpointing<\/h2>\n\n\n\n

The administrator can enable or disable the automatic checkpointing with server restarts either by using javaZoom<\/strong><\/span> tool or by directly modifying server configuration file. Each method is explained below.<\/p>\n\n\n\n
