  - The HCL Commerce application
    Every time you deploy the HCL Commerce application, you are deploying a set of Docker containers that communicate with each other to run your HCL Commerce site. Each HCL Commerce application deployment can contain one or more stores.
  - Overview of administering an HCL Commerce site
    In HCL Commerce the person who performs administrative tasks is called a Site Administrator. The Site Administrator installs, configures, and maintains HCL Commerce and the associated software and hardware. The administrator responds to system warnings, alerts, and errors, and diagnoses and resolves system problems. Typically, this person controls access and authorization (creating and assigning members to the appropriate role), manages the Web site, monitors performance, and manages load balancing tasks. The Site Administrator might be responsible for establishing and maintaining several server configurations for different stages of development such as testing, staging, and production. The Site Administrator also handles critical system backups and resolves performance problems.
  - Staging environment
    an HCL Commerce staging environment is a runtime environment where business and technical users can update and manage store data and preview changes. The changes can then be propagated to the production environment.
  - Workspaces
    You can enable and manage workspace assets and determine policies such as locking rules and commit and publishing options.
  - HCL Commerce database
    As a site administrator, maintain the HCL Commerce database and ensure that any HCL Commerce utilities and processes that load and retrieve data from the database is configured to connect to the database properly.
  - Dynamic caching
    In general, caching improves response time and reduces system load. Caching techniques are used to improve the performance of World Wide Web Internet applications. Most techniques cache static content (content that rarely changes) such as graphic and text files. However, many websites serve dynamic content, containing personalized information or data that changes more frequently. Caching dynamic content requires more sophisticated caching techniques, such as those provided by the WebSphere Application Server dynamic cache, a built-in service for caching and serving dynamic content.
  - Extracting and loading data
    HCL Commerce provides utilities for preparing and loading data into a HCL Commerce database. The loading utilities are flexible and you can continue to use these utilities when you customize the HCL Commerce schema.
  - Payment plug-ins
    To configure a payment plug-in define payment and refund methods; payment and refund rules; and the payment protocols that you intend to use.
  - Search
    In keeping with HCL's commitment to current and open standards, HCL Commerce Search uses Apache Lucene as the basis of its Search framework. Lucene powers the Apache Solr search engine. This open-standards approach considerably eases the process of integrating Search with existing and third-party applications.
  - HCL Customer Service for HCL Commerce
    HCL Customer Service for HCL Commerce is a separately purchased product that provides a light-weight customer service solution that is embedded in the Aurora B2C and Aurora B2B storefronts. Even though this solution is a separately purchased product, it is not a separate application. Stores that are enabled with HCL Customer Service for HCL Commerce allow a customer service representative (CSR) to act on behalf of guest customers and registered customers. A CSR can manage customer accounts, cancel and reorder orders, and shop as customer. A CSR can also act on behalf of Buyer Administrators to help complete Aurora B2B tasks from the storefront, without having to access the Organization Administration Console.
  - HCL Commerce configuration file (wc-server.xml)
    Many aspects of the HCL Commerce runtime application are configured in an XML file. This XML file is located inside the HCL Commerce Java Platform, Enterprise Edition EAR.
  - Enabling the SSL Accelerator option
    An SSL Accelerator (or SSL Terminator) strips off HTTPS encryption at or before the Web server tier in a multitier setup. When you use an SSL Accelerator with HCL Commerce, you can use the SSL Accelerator option to configure HCL Commerce to correctly receive requests that require redirects.
  - Managing features
    You can administer the features for your store and site, such as attribute, catalog, promotion, marketing, order management features, and more. The administration tasks that you can complete differ depending on the type of feature and the tool that you use to administer your store and site.
  - Logging services
    HCL Commerce provides facilities for logging. For existing customers, ECTrace and ECMessage are still supported. For new implementations, use the WebSphere Application Server recommendation for logging and tracing.
    - Configuring logging for runtime environments
      You can handle logging and tracing configurations in your runtime environments by using Run Engine commands.
    - Application server log files
      When you are starting and stopping an application server, a number of log files are generated. After you start or stop an application server, check the log files to ensure that both the application server and the application that runs inside the application server started or stopped successfully.

    - Enabling Management Center client-side logging and tracing
      A Site Administrator can enable logging and tracing for the Management Center to troubleshoot problems that a business user might have while using the Management Center. Client-side logging and tracing refers to tracking all the actions that a business user completes while using the Management Center user interface. By default the debugger window is enabled.
  - Business auditing
    Business auditing is the capturing of the business logic and objects during a HCL Commerce operation. You may want to audit your business for various reasons: generic, such as to review various tasks performed weekly; or specific, such as to track the steps involved in a particular Customer Service Representative's order. A report on business auditing is available in the Administration Console.
  - Business events
    Each time that a command triggers a business event, a record is added to the BUSEVENT database table to persist data from the event. Event listeners and external systems (such as the Marketing component, a back end order management system, or an external analytics system) can use this data to perform further processing.
  - Business Object thresholds
    Applying limits on business operations reduces the risk of system attacks where unbound conditions might result in system failures.
  - Stores in HCL Commerce
    HCL Commerce supports several different types of entities that are defined as stores. The assets of these store entities may be edited using the HCL Commerce Accelerator.
  - Enabling registered users to access all stores in the Extended Sites business model
    HCL Commerce users can access storefronts by virtue of having the role of Registered Customer in the organization that owns the store, or in any organization above it. The roles a user has access to during registration are defined within the MemberRegistrationAttributes.xml file.
  - Hystrix on the Store server
    The Hystrix framework is used as a proxy for back-end resources such as the Transaction server and Search server by default. This can be disabled, but does have performance implications that must be considered.
