Troubleshooting Discover databases
If you are experiencing an access or performance-related issue with your installed Discover SQL database, review the troubleshooting tips in this section, which may help to resolve your issue.
Configuration issues
Use the information in this section to troubleshoot database configuration and data collection issues.
Data collection
Poor data collection performance
If the data collection process is consuming large volumes of memory or failing to finish, you may need to adjust the Data Collector Batch Size setting, which defines the maximum number of records to extract or load for the Data Collector in a single batch. The default value is set to 2000.

      - Configuration issues
        Use the information in this section to troubleshoot database configuration and data collection issues.
        Data collection
        Poor data collection performance
        If the data collection process is consuming large volumes of memory or failing to finish, you may need to adjust the Data Collector Batch Size setting, which defines the maximum number of records to extract or load for the Data Collector in a single batch. The default value is set to 2000.
        Slow data collection times
        Typically, data collection should run in under 5 minutes. If the data collection process is more than 10 minutes, then you should increase the size of the Data Trim Interval setting.
        Database connection timeouts
        If your Discover databases are experiencing repeated timeouts, you may need to adjust the Database Connection Timeout setting. The default connection timeout is set to 30 seconds. After the system was running for a while and traffic was increased, your hardware may not be able to manage the traffic level at the current setting.
        Data collection performance from multiple canisters
        By default, Discover can collect from two canisters at one time. If your environment has more canisters, you can increase the size of the Data Collection - Max Concurrent setting. The appropriate setting depends on your hardware environment.
        Database is getting too large
        If the size of your database is pushing the limits of your storage, you may consider adjusting some settings.
        Error - an existing connection was forcibly closed by the remote host
        When this error occurs frequently, you should check log information as described here.
  - 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.
  - Discover Reference Information
    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.

Poor data collection performance

If the data collection process is consuming large volumes of memory or failing to finish, you may need to adjust the Data Collector Batch Size setting, which defines the maximum number of records to extract or load for the Data Collector in a single batch. The default value is set to 2000.

Note: Do not set this value over 5000.
