How to configure a VCS SQL Server group to monitor and control MSDTC and/or the SQLServerAgent
The VERITAS Cluster Server (VCS) SQL Enterprise Agent is set by default to monitor the SQLServer service only. In some instances, it may be desirable to expand the agent's capabilities and have MSDTC and the SQLServerAgent under the agent's control. This TechNote will describe the procedures for modifying the SQL agent to facilitate control of these resources.
1. Open the VERITAS Cluster Manager; highlight and offline the SQL service group. (Figure 1)
2. Highlight the SQL service group and select Add Resource. (Figure 2)
3. In the Add Resource box, type the name of the resource to be added in the Resource Name section (in this case, MSDTC). Next, select the Generic Service resource from the Resource Type listing. Finally, select the SQL group from the available group listings in the Service Group selection box*. (Figure 3)
4. Once the resources have been added, verify that they appear under the Generic Service resource listing in Cluster Manager, under the SQL service group. (Figure 4)
5. Open Control Panel Services and verify that the MSDTC and SQLServerAgent service startup types are set to manual on both nodes. (Figure 5)
6. Open Cluster Manager and select the Attributes tab. Highlight each of the resources and double-click on the Service Name attribute. Enter the name of the service to be monitored in the Scalar Value box (in this case, MSDTC and SQLServerAgent). (Figure 6)
7. Highlight the SQL service group and select the Resource tab. The new resources that have been added are listed but are not part of the current dependency tree. (Figure 7)
8. Highlight the MSDTC resource and link it to the MSSQL resource so that the MSDTC is the parent resource. If done correctly, the following message will appear. (Figure 8)
9. Highlight the SQLServerAgent and link it to the MSSQL resource so that the SQLServerAgent is the parent resource. If done correctly, the following message will appear. (Figure 9)
10. Through Cluster Manager, right-click on the SQL group and select Online. Confirm that all of the resources come online. (Figure 10)
*Setting the MSDTC and/or the SQLServerAgent resources to critical will cause the entire SQL service group to fault, in the event that either of these resources faults.
