The backup process can be managed with the Backup portlet. Refer to the Teradata Viewpoint Configuration Guide for more information. Restoring Teradata Alerts Database The following procedure restores the Teradata Alerts ("cam") database from a backup made by Viewpoint 14.0 or later. This procedure restores the cam database only. For instructions on restoring Teradata Viewpoint databases along with the Teradata Alerts database, refer to Teradata Viewpoint Configuration Guide. Starting with Teradata Viewpoint 14.0, the backup is performed incrementally for alert log data to improve the overall speed of the backup process. Because log data is backed up incrementally, smaller portions of the data can be restored. You can choose to restore: Teradata Alerts Installation, Configuration, and Upgrade Guide, Release

24 Chapter 3 Administrative Tasks Restoring Teradata Alerts Database Configuration data: restores Teradata Alerts configuration data. Alert log data is not restored. This option drops the cam database and creates it again. Notice: This option deletes all collected data in cam because it creates a new cam database. Current data: restores alert log data in cam for the current week. Data from previous weeks is not restored. Historical data: restores alert log data in cam from previous weeks. Alert log data from the current week is ignored. Everything (default): restores all data in cam. This option drops the database and creates it again. When restoring a backup in a clustered environment, perform the following restoration steps on the primary server. 1 If the Teradata Notification Service is running on a Windows or Linux servers, stop the service. 2 Stop the Teradata Alerts and Viewpoint services on all Teradata Viewpoint servers: /etc/init.d/dcs stop /etc/init.d/tmsmonitor stop /etc/init.d/viewpoint stop /etc/init.d/camalert stop /etc/init.d/tdactivemq stop 3 If the backup files are located on network storage, perform the following steps: a b c Mount the remote host directory on the Teradata Viewpoint server. The remote directory should be the root directory for the backups and should contain the database directory (cam). mkdir /data/restore mount remote host:remote directory /data/restore In the /etc/opt/teradata/cam/cam.properties file, define the value of the backup.dir property to /data/restore. Ensure the directory and file permissions within /data/restore are readable by the postgres Linux user. 4 If the backup files are located on a backup server of a third-party application, perform the following steps: a b c Make a directory on the Teradata Viewpoint server to store the files from the backup server: mkdir /data/restore Copy the files from the backup server to this directory on the Teradata Viewpoint server. This directory should contain the database directory (cam). In the /etc/opt/teradata/cam/cam.properties file, define the value of the backup.dir property to /data/restore. 24 Teradata Alerts Installation, Configuration, and Upgrade Guide, Release 15.00

25 Chapter 3 Administrative Tasks Manually Uninstalling Teradata Alerts Packages d Ensure the directory and file permissions within /data/restore are readable by the postgres Linux user. 5 Run the restore script as follows: For configuration data: /opt/teradata/cam/alert/bin/camrestore.sh conf For current data: /opt/teradata/cam/alert/bin/camrestore.sh curr Note: This option does not attempt to create the cam database and tables, therefore it should be performed after the database has been created by running the conf option. For historical data: /opt/teradata/cam/alert/bin/camrestore.sh hist Note: This option does not attempt to create the cam database and tables, therefore it should be performed after the database has been created by running the conf option. Everything (default): /opt/teradata/cam/alert/bin/camrestore.sh 6 Validate that the script completed successfully by looking for the message RESTORATION OF ALERTS ON server COMPLETED SUCCESSFULLY! If the restoration process failed, an error message is displayed instead of the success message. If the restoration process fails or is interrupted in any manner, fix the problem that caused the failure and execute these steps again. 7 If the backup files are located on network storage, edit the /etc/opt/teradata/cam/ cam.properties file to change the value of the backup.dir property back to / data/backup. 8 If the backup was generated from an earlier version of Teradata Alerts, run /opt/ teradata/cam/alert/bin/setupdb.sh to update the cam repository for Start the Teradata Alerts and Viewpoint services on all Teradata Viewpoint servers: /etc/init.d/tdactivemq start /etc/init.d/camalert start /etc/init.d/viewpoint start /etc/init.d/tmsmonitor start /etc/init.d/dcs start 10 If the Teradata Notification Service was running on a Windows or Linux server, start the service. Manually Uninstalling Teradata Alerts Packages If necessary, you can uninstall the Teradata Alerts packages manually. 1 Use the rpm e command to uninstall each package. For example, to uninstall the camportlets package, run the following command: Teradata Alerts Installation, Configuration, and Upgrade Guide, Release

26 Chapter 3 Administrative Tasks Teradata Notification Service Cluster Configuration rpm -e camportlets 2 Uninstall the packages in the following order: camportlets camalert tdactivemq Teradata Notification Service Cluster Configuration To use BTEQ and Run Program alert actions on Windows, Teradata Notification Service must be installed on a Windows Server. Only one Teradata Notification Service for Windows can run within a Teradata Alerts cluster. To use BTEQ and Run Program alert actions on Linux, Teradata Notification Service must be installed on a Linux Server. Only one Teradata Notification Service for Linux can run within a Teradata Alerts cluster. Teradata Notification Service connects to the active database cache on the Viewpoint server. When the active cache database is promoted, the service automatically connects to the new active database. Teradata Notification Service connects to the messaging service on the Viewpoint server. When a Teradata Alerts messaging service failure occurs, the Teradata Notification Service is automatically reconnected to the secondary messaging service. When the messaging service is restored, the Teradata Notification Service reconnects to the original messaging service. The sections below describe the steps required when enabling or disabling a cluster configuration. Cluster Enabling The Teradata Notification Service may be running when a Viewpoint cluster is configured. The service should initially be configured as the notification service for the server that is to become the primary Viewpoint server. After configuring the Viewpoint cluster, the Teradata Alerts components running on the Viewpoint server are restarted in the new clustered configuration. The Teradata Notification Service automatically detects the configuration change within five minutes and reconfigures the service to operate in a clustered configuration. Cluster Disabling The Teradata Notification Service is aware of the two Viewpoint servers that are part of the cluster configuration. The initial state of the primary and secondary Viewpoint servers is maintained by the service. 26 Teradata Alerts Installation, Configuration, and Upgrade Guide, Release 15.00

27 Chapter 3 Administrative Tasks Teradata Notification Service Cluster Configuration After disabling the Viewpoint clustering, the Teradata Alerts components running on the Viewpoint servers are restarted as two standalone Viewpoint servers. The Teradata Notification Service automatically detects the configuration change within five minutes and reconfigures the service as the Teradata Notification Service for the initial primary Viewpoint server. If this is not the desired Teradata Alerts configuration, the service should be manually configured with the location of the Viewpoint server. About Replacing a Viewpoint Server The Teradata Notification Service is aware of the two Viewpoint servers that are part of the cluster configuration. The initial state of the primary and secondary Viewpoint servers is maintained by the service. If one of the Viewpoint servers is being replaced, it is recommended that the Teradata Notification Service be manually reconfigured to connect to the server that will remain in the cluster. After the Viewpoint cluster is reconfigured, the Teradata Notification Service reconfigures itself. Teradata Alerts Installation, Configuration, and Upgrade Guide, Release
