For an online game, every downtime will have a certain impact on player activity, user experience, operational data, etc., so that most of the downtime and upgrades are carried out in the early hours of the morning. The TcaplusDB upgrade allows the game to run as usual without any impact. How does the TcaplusDB upgrade work? This time we’ll look at the second step: the TCAPDIR upgrade.

1. Upgrade Notes

The version of dir should be consistent with the version of tcapcenter. Generally, the version of Tcapdir should be upgraded after the upgrade of tcapcenter

2. The upgrade process

  1. Click “Operation and Maintenance Platform” ->” Cluster Status “to enter the operation page

  1. Locate the TCAPDIR section and click to expand the list of machines.

  1. Expand the DirsVR part. Since there are few DIR servers, it is suggested to upgrade grayscale one by one. Click the process to be upgraded, and then click the “Batch Local Upgrade” button, or directly click the “Upgrade” field after the process to be upgraded to jump to the upgrade interface

  1. Select the version to be upgraded, check whether the version number is the version to be upgraded, click the button “OK to upgrade”, then the background will enter the upgrade procedure

  1. To find the upgrade transaction, go to the transaction page by following these steps

Locate the Association Name column Processtype: Tcapdir, and click in to see the progress of the upgrade

Or synchronously refresh the “Cluster Status” page to check whether the updated TCAPDIR version is normal. If the version is changed to the target version, the upgrade is successful.

The upgrade process is generally within 10 seconds. If it is found that the Dirsvr to be upgraded is in the red “stop” state for a long time, the upgrade may fail and it is necessary to log in to the machine to check the log.
