The Monitor Server is a separate server from the database server that monitors the Adaptive Server. The Monitor Server can provide real time or historical data to client applications. The Sybase Monitor Server can be protected by the LifeKeeper Sybase ASE resource hierarchy during the resource creation, or added to the LifeKeeper protection after the resource hierarchy creation. In addition, the Sybase Monitor Server can be removed from LifeKeeper protection after the hierarchy has been created.
Adding a Sybase Monitor Server
To add a Sybase Monitor Server to an existing Sybase ASE resource hierarchy, the Sybase srvbuild or other configuration utility must have created one.
- On the Edit menu, select Resource, select Properties. A Resource Properties Wizard will appear.
- Select the resource tag from the Select Resource drop-down. This is the resource tag for the LifeKeeper protected Sybase ASE resource to modify.
- Select the LifeKeeper Server from the Select Server for Resource drop-down. This will be the server to update the Sybase ASE resource instance on. If changes are required on more than one LifeKeeper server, then this process should be repeated for each server in the cluster.
- Select the Resource Configuration button on the Resource Properties page. This will launch a Reconfiguration Wizard for the protected resource selected in Step 3. The first screen of the wizard will display the current configuration settings for the resource under LifeKeeper protection. Select Next.
- If a valid Sybase Backup Server exists, the next screen will allow you to configure it now. Refer to Modifying Protection for the Sybase Backup Server for considerations regarding modifying the Backup Server protection.
- If a valid Sybase Monitor Server exists on the specified server, the next screen will display a drop-down for the Sybase Monitor Server to add or remove. Select the Sybase Monitor Server to add from the list. Select Next. Note: For Sybase ASE installations where the Sybase software is installed on shared storage, the file system containing the installation must be in-service on the server where the reconfiguration will take place.
- Select Reconfigure. If any errors are displayed they must be corrected before proceeding. Otherwise, select Done.
- Any Sybase Monitor Server configuration file paths or associated database devices should be manually protected with a LifeKeeper file system resource and made a dependent of the parent Sybase ASE resource hierarchy.
- The virtual IP address associated with the Sybase Monitor Server must be made a dependent of the parent Sybase ASE resource hierarchy. To find the associated IP address, look for the master and query lines following the Sybase Monitor Server name in the interfaces file.
Removing a Sybase Monitor Server
The following steps outline the process for removing a Sybase Monitor Server from an existing Sybase ASE resource hierarchy.
- On the Edit menu, select Resource, select Properties. A Resource Properties Wizard will appear.
- Select the resource tag from the Select Resource drop-down. This is the resource tag for the LifeKeeper protected Sybase ASE resource to modify.
- Select the LifeKeeper Server from the Select Server for Resource dropdown list. This will be the server to update the Sybase ASE resource instance on. If changes are required on more than one LifeKeeper server, then this process should be repeated for each server in the cluster.
- Select the Resource Configuration button on the Resource Properties page. This will launch a Reconfiguration Wizard for the protected resource selected in Step 3. The first screen of the wizard will display the current configuration settings for the resource under LifeKeeper protection. Select Next.
- If a valid Sybase Backup Server exists, the next screen will allow you to configure it now. Refer to Modifying Protection for the Sybase Backup Server for considerations regarding modifying the Backup Server protection
- If a valid Sybase Monitor Server exists on the specified server, the next screen will display a dropdown for the Sybase Monitor Server to add or remove. Select ‘none’ from the list to remove protection for the Sybase Monitor Server. Select Next.
- Select Reconfigure. If any errors are displayed they must be corrected before proceeding. Otherwise, select Done.
- Any Sybase Monitor Server configuration file paths or associated database devices that are no longer in use should be removed from the Sybase ASE resource dependency and deleted from LifeKeeper.
- Any Sybase Monitor Server virtual IP resources that are no longer in use should be removed from the Sybase ASE resource dependency and deleted from LifeKeeper.
