Administering
Topics in the Administering category highlight tasks that are typically performed by the Site Administrator, to support daily operations of the HCL Commerce site.
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.
Cache invalidation
In order to maintain the relevance of cached data, based on time, user or other variables, the data will have to be invalidated or removed from the cache. Dynacache provides different methods for performing cache invalidation. There are four methods to invalidate the cache.
Removing cache entries through the Cache Monitor
The WebSphere Application Server Cache Monitor provides the options to manually invalidate cache entries.

  - 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.
    - Preparing to use caching in HCL Commerce
      Before you use caching in HCL Commerce, ensure that you prepare. If there are major changes to your caching setup, repeat the preparation steps.
    - Administering caching in HCL Commerce
      An administrator using caching in HCL Commerce should be familiar with full page and fragment caching, Edge Side include, and using the dynamic API not to cache.
    - Cache invalidation
      In order to maintain the relevance of cached data, based on time, user or other variables, the data will have to be invalidated or removed from the cache. Dynacache provides different methods for performing cache invalidation. There are four methods to invalidate the cache.
      - Writing commands for command-based invalidation
        In order to allow a command call be intercepted by the dynamic cache, the command must be written to the WebSphere Command Framework with its implementation class extending from CacheableCommandImpl (in the com.ibm.websphere.command package). To simplify command writing for command-based invalidation, HCL Commerce has updated the abstract classes, ControllerCommandImpl and TaskCommandImpl to extend from CacheableCommandImpl so that any commands extend from these abstract classes would also extend from CacheableCommandImpl and therefore be eligible for command-based invalidation.
      - Defining the invalidation policies in cachespec.xml
      - Adding sample invalidation policies to your store's cachespec.xml file
        You can add invalidation policies that are provided in the sample invalidation files to your store.
      - Removing cache entries through the Cache Monitor
        The WebSphere Application Server Cache Monitor provides the options to manually invalidate cache entries.
      - Cache invalidation using Kafka and ZooKeeper
        You can use Apache Kafka and Apache ZooKeeper to do cache invalidation. Invalidation jobs can be run either from local or remote servers.
    - Dynamic caching considerations with JSTL
      HCL Commerce uses the Java Server Tag Library (JSTL) to create new JSP pages. If <% out.flush(); %> does not surround the <c:import> tag, using dynacache introduces strange behavior. The out.flush statement is required for all <c:import> statements, not just those for fragments. Even if the page is being cached using full-page caching, the out.flush tags are still required to surround the <c:import> tags.
    - Store relationships for cached store pages
      If your store is using data defined in another store through a store relationship, you must use the request attributes specified by the cache filter to define the relationships. The cache filter is a servlet filter that defines request attributes from the session and store relationship information that can be used by the WebSphere Application Server dynamic cache. The dynamic cache then uses this information to construct cache IDs and dependency IDs to be used for cache invalidation.
    - Improving marketing performance by using caching
      To improve marketing performance, use runtime caching to eliminate processing to and from the database.
    - Data recording: Improving runtime performance
      Two options are provided which can improve runtime performance regarding the recording of user behavior data.
    - Clearing the marketing Web service cache
      You can clear the Web service cache to ensure that the content displayed in an e-Marketing Spot is current and relevant.
    - Setting up command caching for catalog filter
      If your site uses catalog filters, you can set up command caching for catalog filter to help improve site performance.
    - Improving store function performance using caching
      To improve store function performance, use runtime caching to eliminate processing to and from the database.
    - Improving store performance through Commerce Composer JSP caching
      There are two types of JSP components within the Commerce Composer solution. Each can be cached for improved site performance.
    - Improving search engine optimization (SEO) performance using caching
      To improve SEO performance, use runtime caching to eliminate processing to and from the database.
    - Improving price rule performance using caching
      To improve price rule performance, you can tune your business object caching and set up dynamic cache invalidation for prices generated by price rules.
    - HCL Commerce data cache
      HCL Commerce contains code to use the WebSphere Dynamic Cache facility to perform caching of lower level computation outputs such as CPU intensive operations, database query results, search query results, and REST request results.
    - HCL Commerce Search caching
      HCL Commerce Search uses fragment caching in the storefront.
  - 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.
  - 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.

Removing cache entries through the Cache Monitor

The WebSphere Application Server Cache Monitor provides the options to manually invalidate cache entries.

Before you begin

Ensure that the cache monitor is enabled. To enable it, see Enabling cache monitoring. When accessing the application, the port of the cache monitor is same as the port of the server endpoints. For the default Store container, this port is 8080/8443. For the Search container, it is 3737/3738.

Procedure

Launch the cache monitor using one of the following methods:
1. You can access the web application using a web browser with the following web address:
```
http://host_name:port/cachemonitor
```
2. However, for a more secure access, it is recommended that you access the Administration host machine:
```
https://admin_host_name:port/cachemonitor
```
3. For example, if the virtual host VH_ instance_name_admin is used for installing the Cache Monitor, then the Cache Monitor can be accessed as:
```
https://admin_host_name:8002/cachemonitor
```

Do one of the following steps:

Option	Description
Remove an entry from cache	Click Invalidate when viewing a cache entry.
Remove all entries for a certain dependency ID	Click Invalidate when viewing entries for a dependency ID or click Invalidate when viewing entries for a template.
Clear the entire contents of the cache	Click Clear Cache while viewing statistics or contents.
Clear the contents on the ESI processors	Click Clear Cache while viewing ESI statistics or contents.
Clear the contents of the disk cache.	Click Clear Disk.
