        Topics in this section describe ways to correct issues with SQL Server configuration.
        Unable to connect to SQL Server
        If Discover is unable to connect to the SQL Server database, try the following steps:
        Failure to install due to model database size mismatch
        During installation of the Discover databases, the Discover Database Manager may report a failure because of a mismatch between the configured database sizes in Discover and the model database sizes that are configured in SQL Server Management Studio.
        Configuring use of SQL Server dynamic ports
        Discover does not natively support use of dynamic ports when accessing SQL Server. If possible, Discover recommends disabling use of dynamic ports.
        Migrating to a new SQL Server
        If you are migrating to a new instance of SQL Server, there are more steps that are required.
        Poor SQL Server performance on 64-Bit operating systems
        Follow this procedure to correct poor SQL Server performance on 64-Bit operating systems.
        SuperSocket information: (SpnRegister): error 1355 in Windows application event log
        If the SQL Server is unable to register a Service Principal Name (SPN), a SuperSocket information: (SpnRegister): error 1355 message is thrown.
        SQL Server blocks access to procedure sys.sp_OAGetProperty
        In some environments, the following error may be displayed in the SQL Server error log:
        Setting the recovery model and logging levels for Discover databases
        To properly maintain the Discover databases, control their size, and improve performance, Discover recommends using the Simple Recovery Model for SQL Server and compressing the log files.

        Topics in this section describe ways to correct issues with Discover database configuration.
      - Configuration issues
        Use the information in this section to troubleshoot database configuration and data collection issues.
  - Report Access Permissions
    Users whose accounts contain the proper permissions may administer Discover reports. Depending on the type of report, permissions to administer individual reports of that type are configured in the report definition.
  - Managing User Agents
    Through Discover, you can monitor the different types of user agents that contact your web application. Through a provided set of data objects, Discover can identify the type of traffic that is requesting resources from your web application and then monitor counts and other information that pertains to the type of user agent. These objects can be used as the source data for developing a useful set of user agent-related reports, enabling you to closely monitor the composition of traffic to your site.
  - Configuring User Agent Detection
    This section describes how to acquire and maintain the configuration files necessary for parsing of fixed and mobile user agents and how to prepare those files for use in the HCL Discover platform.
  - Configuring User Agent Events
    To use the data that is injected into the [ExtendedUserAgent] section by the Discover SessionAgentTLTRef, a Discover administrator must create events that create charts for this data.
  - User Agent Tools
    These external utilities can be used to monitor and update user agent configuration data that is required by Discover.
  - bot Detection
    Most commercial enterprise web applications are subjected to significant traffic from web crawling bots. Short for "robot," a bot is a software agent that navigates websites to extract information about them. Some bots are used by search engines for indexing pages.

    Use the links below to access reference information on file formats, common standards, and more in use by the Discover system.
  - Integrating HCL Discover and Unica Journey
    HCL Discover and Unica Journey integration works with CEP configuration. The CEP configuration enables the event to be sent to CEP and the external systems. Unica Discover-Unica Journey integration is supported from version 12.1.0.3 onwards.
  - Integrating HCL Discover and Unica Interact
    HCL Discover and Unica Interact integration works with CEP configuration. The CEP configuration enables the event to be sent to CEP and the external systems. Unica Discover-Unica Interact integration is supported from version 12.1.0.3 onwards.
  - Selective Deletion
    You can delete sessions and session fragments from the HCL Discover system with the Selective Deletion tool.
  - Using the ArchiveConfig utility
    Run the ArchiveConfig utility to configure and execute Selective Archiving.
  - ELK Configurations
    Before configuring ELK on HCL Discover, there are some prerequisites:
  - Securing Interprocess Communication
    Discover 12.1.8 and above supports the use of a new SSL certificate based mechanism for securing all inter-process communication between the Discover servers. This is important in a distributed environment with multiple servers, as the components of Discover communicate with each other over the network, using a variety of ports.

Unable to connect to SQL Server

If Discover is unable to connect to the SQL Server database, try the following steps:

About this task

Procedure

SQL Server custom ports
- By default, SQL Server listens on port 1433, which is also the default communication port for Discover, unless selected differently during installation. You can verify this value through the SQL Server Configuration Manager.
Unable to connect through dynamic ports
- If your SQL Server implementation uses dynamic ports, you must sync your Discover solution with them. See Configuring use of SQL Server dynamic ports.
SQL network protocols
- By default, SQL Server does not enable TCP and Named Pipes, which are used by Discover. Verify that these protocols are enabled through the SQL Configuration Manager.
