WCP: Profile de Usuario, Cache, Sincronización y LDAP

Existen varios niveles de Caché y API que se debe entender con respecto a los perfiles de usuario en WebCenter Portal.

En el siguiente diagrama ilustro los distintos niveles que existen

Diagrama ilustrando las capas que participan en el Profile de WebCenter

Lo importante del diagrama es:
  1. La petición de la página de perfil o información de usuario pide al API de WebCenter Portal la información.
  2. WebCenter Portal API ofrece dos capas de API.
    • Acceso a través de la Java Object Caché a la información del usuario. (WebCenterSecurityUtils / WCSecurityUtility classes) Es la ilustada en la imagen
    • Acceso directo para obtener la información refrescada. (UserCacheManager class)
  3.  La Java Object Cache y la información de usuario es recogida del esquema de WebCenter Portal.
  4. El esquema de WebCenter Portal se refresca con la información de LDAP a través de procesos de sincronización.
A niveles de configuración es importante saber que:
  • La información de Caché, sincronización de las fotos con LDAP y tamanyo de batches de LDAP puede ser configurada en la Administración de WebCenter Portal en la sección de Tools & Services.
    Propiedades de Caché y LDAP de la consola de Administración para los Perfiles de Usuario
  • Mediante la función WLST setProfileConfig un administrador puede establecer los parámetros expuestos en la consola de administración además de establecer los parámetros ProfileSyncHourOfDay, ProfileSyncFrequencyInDays para configurar cada cuanto tiempo se hara la sincronización LDAP - Database.
Por otro lado remarcar el uso del API.

Las siguientes llamadas sacan la información de usuario de Java Object Caché. 
WebCenterSecurityUtils.getUserFromUserName 
WCSecurityUtility.getUserFromUserName

La siguiente llamada fuerza obtener la información de usuario de LDAP.
UserProfile userProfile = UserCacheManager.findUserFromUserName(username).getUserProfile();

OJET: Inter-Module communication in TypeScript Template

Image
In this post I bring another example on how to Communicate Modules using the Oracle JET - TypeScript Template based on the Oracle JET Cookbook: InterModule Communication From now and so on will create multiple examples using TypeScript for those who are not familiar with it and wants to turn the Cookbook examples into TypeScript :). The example ( ojet-typescript-list-detail ) can be found as usual in my GitHub repository: https://github.com/DanielMerchan/ojet-examples This example is a bit different compared to the Cookbook example where the modules are not running at the same time within a Module. This example is built as described in the following images: Customers module acts as the Wrapper Module. It coordinates when to load the list and detail modules. Customers module makes use also of signals npm module for communication between Customers-List, Customers-Detail. Explanation of the Example customers.js is the coordinator responsible module for: initiali

OJET: Build and Deploy in an Application Server

Image
There are some other sources where an Oracle JET Application is packaged and deployed as a WAR in Oracle WebLogic Application Server (Arda Eralp) https://blogs.oracle.com/ardaeralp/deploy-oracle-jet-application-to-weblogic-server (Andrejus Baranovski's) http://andrejusb.blogspot.com/2016/07/serving-oracle-jet-application-from.html They may look bit old or maybe because they call directly grunt tasks by using the grunt-cli . In this post I will update a bit these posts in Oracle JET 6.1.0 and the usage of ojet build (instead of calling the grunt tasks) for also building the corresponding WAR file. The example can be found in my GIT repository: https://github.com/DanielMerchan/ojet-examples Let's start... Install grunt-war module in your Oracle JET Application. npm install grunt-war --save-dev Create a war.js (or call it whatever you want) in /scripts/grunt/config folder under your souce files. This is a sample code inside of it, check https://www.npmjs.com/packag

OJET: Select All options using only Checkboxset

Image
This is an example on how to select all other options by using another oj-checkboxset. GitHub: ojet-checkbockset-select-all The idea is to keep track of the selection and make use of the on-value-changed as described in the following code. self.colorOptions = ko.observableArray([ { id: "blueopt", value: "blue", color: "Blue" }, { id: "greenopt", value: "green", color: "Green" }, { id: "redopt", value: "red", color: "Red" }, { id: "limeopt", value: "lime", color: "Lime" }, { id: "aquaopt", value: "aqua", color: "Aqua" }, ]); self.selectAll = ko.observableArray([]); self.currentColor = ko.observableArray(["red"]); self.selectAllOptionChanged = (event) => { const newSelection = event.detail.value; if (newSelection.indexOf('all')
