Known Issues for Siebel HI Client with un-supported Internet Explorer 9, 10, 11 and Edge versions (IE9 , IE10 , IE11, Edge) (Doc ID 1627168.1)

Last updated on APRIL 01, 2021

Applies to:

Siebel CRM - Version 8.1.1.10 [23021] and later
Information in this document applies to any platform.

Details

Summary:

Only IE8 is supported with HI client.  Other browsers are not supported.  Customers using other browsers should implement Open UI.

Siebel clients have provided industry-leading innovation on Internet Explorer 5.5 since version 7.02 of Siebel. Both Siebel and Internet Explorer have evolved over the years to provide increasing amounts of leading edge features. In its first generation of software these features were initially provided using Microsoft’s proprietary ActiveX framework.  The IP2015 HI Client for Siebel applications is today supported with use of IE versions up to IE8.  It should be noted that Microsoft has ended mainstream support for IE8, IE9 and IE10 on January 12th, 2016.  As of that time Microsoft has not patched Internet Explorer 8 for any functional issues.  Oracle has provided support directives for IE8 and HI in the following Statement of Direction: Statement of Direction IP2016 Client Platform Support  Oracle provides Support for IE11 and Edge, only with the new Open UI client and Siebel Mobile product offerings.

Microsoft’s backward compatibility: IE9 IE10, IE11 and Edge Changes

Internet Explorer 9 and above have a new rendering layout engine, a new JavaScript layout engine and a new CSS layout engine. Internet Explorer 9 and above require ATL library changes for ActiveX that impact functionality and introduce other regressive security changes.  These advances in functionality have been made in IE9 and above, but backward compatibility has been lost as a result.  The links below by Microsoft and other sources show changed interfaces. The links are not a comprehensive summary, but all of these changes in backward compatibility aggregate.  This puts at high risk proper function of Siebel HI client on browsers other than IE8.   

Microsoft Compatibility Mode and Enterprise Mode.

Compatibility mode attempts to resolve some of the backward compatibility issues to emulate legacy behavior. Though Microsoft documentation implies that only some functional issues can be addressed with compatibility mode, this does not remediate a large amount of functionality required by Siebel.  "Compatibility mode" refers to compatibility with legacy proprietary behavior.

IE11 and Edge offers a new feature called Enterprise mode.  Enterprise mode addresses some but not a great number of compatibility issues, again not addressing any of the ActiveX compatibility issues between those and older browsers.In order to force the Compatibility View to True via Group Policy can be done as per below reference to blog.

To clarify backward compatibility of Enterprise Mode to native IE8, Microsoft has provided the following information:

Problems found:  Empirical Data

Oracle has aggregated empirical evidence that validate the overall lack of backward compatibility  The list includes, but is by no means limited to:

All UI elements in HI client are win32 controls. Any change in above said layers affects creation, drawing and painting of these elements. IE guides logic in the application. Enterprise mode provides IE version through a user agent but it doesn’t guarantee usage of IE8 through virtualization.
A partial list of Siebel specific symptoms known from anecdotal and or unintended usage of Siebel HI client on IE browsers that are not certified are provided below.  This list is only a small snapshot and is only representative of the types but not extent of all issues that may be encountered that would require mitigation by Microsoft. Any one of the listed issues may impact deployments as a high severity issue depending on the use case.
Crashes:
  • While doing File --> Logout , Application crashes
  • If a modal confirm box is called from a pick/MVG applet, the Siebel application crashes (hangs and doesn’t respond). User has to end and restart the Siebel session.

Functional Issues

  • Attached Network File URL’s do not work
  • Configurator Tree applet does not display
  • Keystrokes not registering as input in UI
  • When the Mouse is over a Hyperlink, it is not changing to “Hand” sign, it stays as it is
  • When using short keys (like Ctrl+Alt+K) short cut keys only work intermittently.
  • When navigating to Analytics Reports page in Siebel Application, the OBIEE login page is shown instead of reports and only on providing user credentials, reports are shown
  • Pick List or MVG Applets not closing by X button
  • Not able to perform 'Sent to SC' via refresh policy for Claims
  • hourglas does not come up for scripting and workflow and other time consuming operations

Focus, formatting,navigation issues & Error messages

  • Stylus does not work fully on activeX components in the UI
  • When using short keys (like Ctrl+Alt+K) pop-up windows appears in the back ground, and the short cut keys do not always work.
  • When there is a delay in response, Internet Explorer shows a message indicating that the server is not responding with a button offering to recover the session.
  • Various UI related error messages in the UI such as “The applet field with name “s_1_2_45_0” doesn’t exist(SBL-UIF-00289)”
  • Various data related error messages in the UI such as “Genericc SSA NOTOK error message.)SBL-DAT-00472)”Rep tool F9 functionality works fine on IE10 with “http” URL but once we enable “https", it’s does not work as on IE8
  • A modal confirm box, when invoked from a form or list applet, disappears in the background.  User has to minimize all windows and find the pop up window to proceed ahead with their task.
  • When trying to open a MVG applet the pop-up applet appears in small size in top left 

Integration issues

  • Third party embedded integrations such as OBIEE, Chart Server, BIP and third party products may not function correctly or Enterprise mode may interfere with rendering of these components.

Microsoft’s Support and Lifecycle  Information for IE

Customers are advised against use of running legacy applications like Siebel HI client on new Internet Explorer browsers. Customers are encouraged to understand Microsoft’s end of life milestones of Internet Explorer such as IE8, 9 and 10 during this time of transition as well as Microsoft's commitment to backward compatibility on new browsers.  the Internet Explorer lifecycle information is available at http://support.microsoft.com/gp/microsoft-internet-explorer.  

Oracle’s HI Client Support Commitment and Lifecycle

Oracle is committed to support the HI client on Internet Explorer 8 for Innovation Pack 2015 via patchsets.  Support is outlined in https://support.oracle.cI Hom/epmos/faces/Certify Select the Certifications tab, and enter "Siebel HI Web Client" as the product name to check if it has a current certification listed.  If listed as certified it will be supported for the listed distribution but not enhanced with new features.  Certain limitations such as limited ability to affect fixes for end of life browser versions are in effect.

What Oracle can commit to and recommend

Oracle’s recommendation is moving deployments requiring IE11 or Edge browsers directly to Open UI clients based on the fact that many customers are able to quickly make that transition. Total cost of ownership, increased technology transparency and freedom in browser choices are overwhelming benefits.  Oracle aims to assist customers in understanding options and practical actionable data to minimize risks to their mission critical applications. 

Oracle recommends customers to evaluate the Open UI client as the next generation of Siebel Clients.  The requirements for Open UI are detailed in <note:1499842.1> under the section "Open UI Requirements". Internet Explorer 11, Edge, Chrome, Safari and Firefox provide excellent HTML5 support to run Open UI with noted limitations.  Open UI can be deployed efficiently and provides the next generation of the most innovative CRM solution available in Siebel Open UI. Introductory information on Open UI can be found at Open UI Deployment Guide <note:1499842.1>.  The Open UI Deployment Guide <note:1499842.1> also contains benchmark data for a variety of hardware and browser combinations, Oracle encourages customers to review perfomance on their hardware and browser prior to deploying Open UI.  Siebel Open UI provides a modern customer experience on new browsers.

Note: IE9 does not fully meet HTML5 standards and thus has limitations in running Open UI, both in performance and functionality.  Only use IE9 with Siebel Open UI if the known limitations are acceptable to the required use scenarios. 

In Summary

IE9, IE10, and IE11 provide significant challenge in meeting backward compatibility toward IE8, as they are shown not to be 100% backward compatible based on Microsoft and other information. As a result, Oracle strongly advises customers against, and cannot support use of IE versions other than 8 with Siebel HI client.  Customers must reproduce any HI client support issue on Internet Explorer 8. IE 8 issues may have dependencies on Microsoft's lack of supportof IE8, (end of life).

Oracle recommends Open UI as the modern and secure platform of choice for Siebel deployments running on modern browsers.
