Administering
This documentation provides information about the administration tools for managing and monitoring IBM Domino® servers and databases.
Managing servers
Manage Domino® servers by performing any of these tasks.
Managing a cluster
After you have set up a cluster, you can perform tasks to manage it.
Managing database availability in a cluster
There are three database attributes that let you specify whether a database is available for user access.
Making a database unavailable for user access
On occasion, you may want to make a database unavailable for user access. You would do this if you want to do some maintenance on the database or if you want users to fail over to a different replica of the database because the server is reaching a high level of use. To make a database unavailable to users, you mark the database as out of service.

- Administering
  This documentation provides information about the administration tools for managing and monitoring IBM Domino® servers and databases.
  - Administration tools
    Topics in this section describe the tools you can use to administer a Domino® server.
  - Monitoring
    This section describes how to use the tools and features that help you monitor a Domino® system.
  - Managing servers
    Manage Domino® servers by performing any of these tasks.
    - Changing the server administrator
      If the name of the former administrator is explicitly listed in the access control list (ACL) for the Domino® Directory, delete the name of the former administrator from the ACL. Add the name of the new administrator and assign the administrator Manager access.
    - Setting and managing passwords for the server console
      Set server console passwords to protect against unauthorized use of the server console.
    - Decommissioning a Domain Search server
      If you want the server that creates full-text indexes of the Domino® domain to resume duty as a regular Domino server, remove it from the appropriate group in the Domino Directory, edit its Server document, and then delete some files from its directory structure.
    - Decommissioning a server
      You use the Decommission Server Analysis tool when you are consolidating existing servers and/or permanently removing a server from service. Whether you are combining two servers into one server or renaming a server, the result is the same -- the old server name is replaced with the new server name.
    - Deleting a server name
      You can use the Administration Process to delete references to a server from the Domino® Directory, and from database ACLs and Extended ACLs. The Administration Process automatically deletes mail-in database documents and cross-certificate documents as necessary during the Delete Server process.
    - Dropping user sessions on a server
      Dropping user sessions from a server may be useful when you need to make a database or server temporarily unavailable to correct a problem; users can reconnect after you are ready. You can drop one user session or all user sessions for the current database, or selected user sessions, from the server.
    - Finding a server name in the domain with the Domino® Administrator
      You can search for a server name in the domain and then view a log that includes document links and directory links to each occurrence of the server name.
    - Recertifying a server ID
      Use the original certifier to recertify a server ID that has a certificate that is about to expire.
    - Uninstalling a Domino® partitioned server
      You can remove all server partitions from a computer or you can remove just one server partition.
    - Reinstalling or moving a Domino® server from one computer to another
      Use this procedure to reinstall a server if an error occurs and the installer does not complete during the install of an incremental installer, or if the Domino® server is crashing and troubleshooting does not reveal the root cause.
    - Transaction logging
      Domino® transaction logging captures changes made to a database and writes them to a transaction log. The logged transactions are then written to disk in a batch, either when resources are available or when scheduled.
    - Installing and running NSD as a Microsoft™ Windows™ service
      Installing and running NSD as a Microsoft™ Windows™ service is no longer available as of IBM® Domino® 10.
    - Setting up a Fault Reports database
      The Notes/Domino Fault Reports database stores data that is collected at the time of a server crash. Data is collected from both the client and the server and can then be used to measure client reliability and determine the areas where problems exist.
    - Client and server diagnostics
      Use these tasks to perform client and server diagnostics to collect diagnostic information after a server or client crash.
    - Collecting diagnostic information after a server or client crash
      The automatic diagnostic collection tool collects diagnostic data after server and client crashes and sends the collected data to a mail-in database when the server or client restarts. You can then use the collected data to determine the cause of the crash.
    - Using the IBM_TECHNICAL_SUPPORT directory
      The IBM_TECHNICAL_SUPPORT database contains data that has been collected using the Domino® Configuration Collector and the Automatic Diagnostic Data Collection tool. It also includes system information files and documents that have been exported from the Domino Directory and saved as .dxl documents using the Save command entered at the Domino server console.
    - The Domino® server log file (LOG.NSF)
      Every Domino® server has a log file (LOG.NSF) that reports all server activity and provides detailed information about databases and users on the server. The log file is created automatically when you start a server for the first time.
    - Controlling the size of the log file
      By default, the log file (LOG.NSF) records information about the Domino® system.
    - The Domino® Web server log (DOMLOG.NSF)
      You can log your server activity and Web server requests to the Domino® Web server log (DOMLOG.NSF) database. This option may be preferable if you want to create views and view data in different ways.
    - Using console log mirroring
      Console log mirroring causes a new server thread to be created which monitors all messages written to the Console Log file and duplicates these messages into another file. When this new file is filled, the thread closes the mirrored file and creates a new file into which subsequent messages are written. You can delete the closed mirrored files at your discretion.
    - Using the Domino® Configuration Tuner to evaluate server settings
      The Domino® Configuration Tuner (DCT) evaluates server settings according to a growing catalog of best practices. All servers in a single domain can be evaluated together. DCT generates reports that explain the issues DCT uncovers, suggests mitigations, and provides references to supporting publications.
    - Activity Logging
      You use activity logging to collect information about the activity in your enterprise. You can use this information to charge users for the amount they use your system, monitor usage, conduct resource planning, and determine if clustering would improve the efficiency of your system.
    - Managing a cluster
      After you have set up a cluster, you can perform tasks to manage it.
      - Balancing the workload in a cluster
        After monitoring your cluster and determining that you want to make an adjustment, you can perform the following tasks to better balance the workload across the servers in a cluster.
      - Improving server availability in a cluster
        Clusters are designed to improve server availability.
      - Managing failover in a cluster
        When you set up a cluster, you create replicas of databases so that users fail over automatically to a different replica if the database or server they try to access is unavailable.
      - Streaming cluster replication
        Streaming cluster replication (SCR) takes advantage of the fully-connected nature of clusters and data streaming to produce a low-overhead cluster replicator.
      - Managing replication in a cluster
        You should use both cluster replication and standard replication in a cluster and run them both at the same time. Cluster replication is the primary means of replication in a cluster, while standard replication updates any databases that the Cluster Replicator couldn't update.
      - Configuring and controlling cluster replication
        When you add a server to a cluster, Domino® starts the Cluster Replicator automatically. Each time you start the server, the Cluster Replicator starts. You can also control cluster replication in various ways, such as disabling, pausing, and resuming it.
      - Creating configuration settings for all servers in a cluster
        If there are configuration settings that you want to apply to some or all servers in a cluster, you can create a Configuration Settings document that applies to the servers you want.
      - Managing database availability in a cluster
        There are three database attributes that let you specify whether a database is available for user access.
        Making a database unavailable for user access
        On occasion, you may want to make a database unavailable for user access. You would do this if you want to do some maintenance on the database or if you want users to fail over to a different replica of the database because the server is reaching a high level of use. To make a database unavailable to users, you mark the database as out of service.
        Restoring access to out of service databases
        You can restore access to a database that was taken out of service by changing its service status. After a database is returned to service, it becomes fully available to users again.
        Deleting databases from a cluster
        To minimize disruption to users, you can set a database to be deleted after every active user has finished using the database. To do this, you mark the database as Pending delete. When a database is pending delete, the database does not accept any new database open requests. After all users have closed the database, Domino® pushes changes to another replica and then deletes the database.
      - Adding a server to a cluster
        Use the administration server when adding a server to a cluster. The administration server does not have to be part of the cluster.
      - Removing a server from a cluster
        Use the administration server when removing a server from a cluster. The administration server does not have to be part of the cluster.
      - Moving a server from one cluster to another
        To move a server from one cluster to another, you simply add the server to the new cluster. Domino® automatically removes the server from the old cluster.
      - Viewing information in the Cluster Database Directory
        The Cluster Database Directory contains one document for each database in the cluster. The document tells you such information as the server, path, and replica ID of the database; whether cluster replication is enabled for the database; and whether the database is out of service or pending delete. The Cluster Manager and the Cluster Replicator use this information to determine if the database is available and how to access it during failover and cluster replication, respectively.
  - Managing databases
    Topics in this section describe how to set up and manage Domino® databases.
- Tuning
  Use this information to improve IBM® Domino® server, Domino Web server, and messaging performance through the use of resource balancing and activity trends, Server.Load commands, advanced database properties, cluster statistics, and the Server Health Monitor.

Making a database unavailable for user access

On occasion, you may want to make a database unavailable for user access. You would do this if you want to do some maintenance on the database or if you want users to fail over to a different replica of the database because the server is reaching a high level of use. To make a database unavailable to users, you mark the database as out of service.

About this task

When you mark a database as out of service, users cannot open the database. Open database requests fail over to a replica, if one is available. If no replica is available, Domino® denies users access to the database and displays an explanatory message.

Users who are using the database when you mark it as out of service continue to have access until they close the database. If users close an out-of-service database and then try to reopen it, they fail over to another replica on an available server, if there is one. This means that the database is gradually brought to an OUT OF SERVICE state without disruption to users who are actively using it. In addition, replication updates from other replicas continue to occur even when a database is marked as out of service.

Procedure

In the Server pane of the Domino® Administrator or the Web Administrator, expand either All Servers or Clusters.
Select the server that contains the database you want to mark out of service.
Click the Files tab.
Do one of the following:
- In the Task pane in the Domino® Administrator or the Web Administrator, select the folder or view that contains the database you want.
- In the Task pane in the Domino® Administrator only, expand Cluster Directory, and then select the view you want.
In the Results pane, select the database or databases you want.
In the Tools pane, expand Database, and then click Cluster.
Click Out of service, and then click OK.

What to do next

To mark all databases on a server out of service, when managing failover, use the SERVER_RESTRICTED setting. A restricted server does not accept new database open requests.
