SAS Environment Manager 2.3 provides the ability to display and monitor four SAS Metadata Server cluster-specific resources: By selecting a node in the cluster and connecting to it, you can control either the individual node or the entire cluster, depending on your selection. Individual nodes within the cluster can be viewed by using the Server Manager plug-in under SASMeta – Logical Metadata Server. Here’s a screenshot of the Cluster tab in Metadata Manager in SAS Management Console. Additional functionality has been added to the Metadata Manager to display the overall status of the cluster, including the presence or absence of a quorum. SAS Management Console enables you to view the overall status of a metadata server cluster and to individually monitor each node in the cluster. In this blog post, I’ll share two different tools that you can use. A clustered SAS Metadata Server keeps its data in sync, balances its workload, and continues to handle requests if a node fails – all while presenting a single face to the outside world.īecause the SAS Metadata Server supports all the SAS applications in your environment, it’s important to monitor the performance and availability of the servers in the cluster. The metadata server cluster reduces single-point-of-failure concerns for the SAS Metadata Server. The SAS 9.4 Metadata Server cluster was introduced to help address this need.Ī SAS Metadata Server cluster is a coordinated set of metadata servers that act as a single metadata server for a SAS software deployment.
