Article Title:   "IBM WebSphere Portal V 8.5 Performance Tuning Guide"                
Authors:  Multiple Portal Testers and Developers
Link: http://www-10.lotus.com/ldd/portalwiki.nsf/dx/IBM_WebSphere_Portal_V_8.5_Performance_Tuning_Guide
Summary:     This white paper provides a basis for parameter and application tuning for IBM WebSphere Portal for Multiplatform and for Linux on System Z V8.5.0. Remember that both tuning and capacity are affected by many factors, including the workload scenario and the performance measurement environment. For tuning, the objective of this paper is not to recommend that you use the values we used when measuring our scenarios, but to make you aware of those parameters used in our configuration. When tuning your individual systems, it is important to begin with a baseline, monitor the performance metrics to determine if any parameters should be changed and, when a change is made, monitor the performance metrics to determine the effectiveness of the change.

Articles and White Papers

Article Title:   "Warming up your Portal Site"             Posted 26-May-2015
Author:   Travis Cornwell - Portal L2 Support
Link: https://www.ibm.com/developerworks/community/blogs/PortalL2Thoughts/entry/warming_up_your_portal_site?lang=en
Summary:
  WebSphere Portal leverages a large number of caches throughout the product.  Caches offer may advantages to the WebSphere Portal product - most notably they allow for significant performance improvements when the Portal server is under load.  When a Portal server is restarted the caches are emptied out.  In the event of a planned (or unplanned) outage of the Portal server - it can take a bit of time for the caches on a Portal server to become repopulated following a Portal server restart.  When accessing the Portal server in a "cold" state without the caches filled in yet, this can leave the end user experience degraded.  In this article, we will discuss warming up the Portal server using a series of scripted operating system commands.  


Article Title:   "How to programatically refresh data from LDAP during login"             Posted 26-May-2015
Author:   Travis Cornwell - Portal L2 Support
Link: https://www.ibm.com/developerworks/community/blogs/PortalL2Thoughts/entry/how_to_programatically_refresh_data_from_ldap_during_login?lang=en
Summary:
  WebSphere Portal leverages a large number of caches throughout the product.  Caches offer may advantages to the WebSphere Portal product - most notably they allow for significant performance improvements when the Portal server is under load.  When users login to the Portal server, logout, and then relogin, they may not see the most recent data available from the LDAP server.  This is discussed in detail in a prior blog entry - How to programatically refresh data from LDAP.  This blog article will discuss implementing custom authentication filters that will leverage reload() code and pull updated user data from LDAP during login.  Sample code is available at the end of each respective section for download and implementation.


Article Title:   "Determining the Number of Users Logged Into Portal"             Posted 26-May-2015
Author:   Travis Cornwell - Portal L2 Support
Link: https://www.ibm.com/developerworks/community/blogs/PortalL2Thoughts/entry/determining_the_number_of_users_logged_into_portal?lang=en
Summary:
  For purposes of this blog entry - we will define the number of logged in users to Portal to be roughly equivalent to the sessions that exist in the Portal.  The blog entry proceeds to describe how to enable PMI in WAS to monitor the session count in Portal and get an approximation of the number of logged in users.


Article Title:   "How to Find Leaky Sessions in Portal"             Posted 26-May-2015
Author:   Travis Cornwell - Portal L2 Support
Link: https://www.ibm.com/developerworks/community/blogs/PortalL2Thoughts/entry/how_to_find_leaky_sessions_in_portal?lang=en
Summary:
  This blog entry will discuss utilizing a tool which will help in determining where session leaks may exist in WebSphere Portal.



Article Title:   "Resolve "Too Many Open files error" and "native OutOfMemory due to failed to create thread" issues in WebSphere Application Server running on Linux"             Posted 26-May-2015
Author:   Saritha Muluka - WAS L2 support
Link: https://www.ibm.com/developerworks/community/blogs/aimsupport/entry/resolve_too_many_open_files_error_and_native_outofmemory_due_to_failed_to_create_thread_issues_in_websphere_application_server_running_on_linux?lang=en
Summary:
  This blog entry describes how to troubleshoot two common error messages for WAS/Portal on Linux.  From the blog author - "We receive quite a few problem records (PMRs) / service requests (SRs) for native OutOfMemory issues in WebSphere Application Server and one of most famous native OOM issues happens particularly on Linux OS due to insufficient ulimit -u(NPROC) value.  We also receive a good number of PMRs for "Too many Open Files" error for WebSphere Application Server running on Linux.  With simple troubleshooting and ulimit command tuning, you can easily avoid opening a PMR with IBM support for these issues.".


Article Title:   "How to create a shared library and associate it with the application server or enterprise application on WebSphere Application Server"             Posted 26-May-2015
Author:   Thanh Giang - WAS L2 support
Link: https://www.ibm.com/developerworks/community/blogs/aimsupport/entry/create_shared_library_and_associate_it_with_the_application_server_or_application_on_websphere_application_server?lang=en
Summary:
  This blog entry describes how to create a shared library and associated with a WAS server or WAS application.  This can be useful for custom applications or custom code deployed to WebSphere Portal where a custom location for the code libraries needs to be specified, rather than placing the code in the /PortalServer/shared/app or /AppServer/lib directories, which is generally not recommended.


Article Title:   "Live Branding in IBM Sametime Connect Client 8.5"             Posted 12-May-2015

Article Title:   "WebSphere Commerce Sample for IBM Digital Data Connector in WebSphere Portal"             Posted 05-May-2015
Author:   Jonathan Booth - Portal Development
Link: http://openntf.org/main.nsf/project.xsp?r=project/WebSphere%20Commerce%20Sample%20for%20IBM%20Digital%20Data%20Connector%20in%20WebSphere%20Portal/summary
Summary:
  IBM Digital Data Connector (DDC) is used to integrate data from external data sources on your portal pages by using IBM Web Content Manager presentation components. In this sample we are integrating WebSphere Portal and WebSphere Commerce. This integration allows WebSphere Portal to become a front-end for WebSphere Commerce pulling data into portal using the WebSphere Commerce REST APIs. WebSphere Commerce can then behave in a “headless” manner, acting as a data source for WebSphere Portal.

Functionality available in the default WebSphere Commerce storefront, Aurora, has been segregated into portlets which use a combination of DDC and AJAX. The library provided in this sample contains 16 content items which you can drag and drop onto your portal pages. Each content item corresponds to a function available in the Aurora Store front, for example a shopping cart or wishlist. These content items are provided as examples of how you can easily integrate WebSphere Portal and WebSphere Commerce using DDC. 


Article Title:   "Integrating WebSphere Portal and Commerce via REST Services"             Posted 05-May-2015
Author:   Dmitri Nevedrov - IBM IT Architect
Link: http://www.ibm.com/developerworks/commerce/library/co-websphereintegration/index.html
Summary:
  You can integrate WebSphere Portal and the WebSphere Commerce with the REST (Representational State Transfer) mechanism that is provided by WebSphere Commerce. You can also enable a single authentication mechanism for the system and integrate Web Content Manager.  [The author proceeds to describe step-by-step the configuration changes needed for both Portal and Commerce to integrate.  Further notes are given on use case scenarios - including sample code, for integrating the two products].
