Overview

• New Features in InTouch 2012

• Mind Map View 100% CPU Issue

• Process Explorer

• View Crash Causes and Solutions

Slide 5

New Features in InTouch 2012

• Smart Card• Show/ Hide Graphics• Tag Viewer• WWHeap Setting • Windows Memory Caching• CPU Affinity• Lock Window Size – Scale For Resolution• GetWindowName Script Function

Slide 6

Smart Card

InTouch utilizes the following smart card related APIs exposed by Microsoft.

Note: The AppServer xxSecurity also utilizes these APIs to support smart card authentication for the Galaxy OS authentication using smart card.

Windows Smart Card APIs will be used to detect the presence of the smart card

in the system. Refer to the following  link for details:

http://go.microsoft.com/fwlink/?LinkId=93347

Microsoft Cryptographic services will be leveraged to read certificates that are

stored in the smart card. Refer to following link for details:

http://msdn.microsoft.com/en-us/library/ms925963.aspx

Slide 7

Smart Card Hardware

• C2-40 Mini Driver Smart Card

• OK 3021 USB Smart Card Readers

Slide 8

Show/Hide Graphics

• The Show/Hide Graphic script functions allow you to write ArchestrA Graphics scripts to display a symbol as a pop-up window and close the pop-up window.

• The HideGraphic script function allows you to close any ArchestrA symbol, displayed through the ShowGraphic script function.

• The HideSelf script function allows you to close the symbol, displayed by either the ShowGraphic script function or the ShowSymbol animation.

Slide 9

Show Graphic Function Structure

Dim graphicInfo as aaGraphic.GraphicInfo;

graphicInfo.Identity = "<Identity>";

graphicInfo.GraphicName = "<SymbolName>";

ShowGraphic( graphicInfo );

Slide 10

Show/Hide Graphic Script Tips and Examples

The Show/Hide Graphic script functions allow for a wide range of

scripted uses:

• Using Predefined and Named Scripts

• Working with Modal Windows

• Using Hierarchical References and Containment Relationships

• Scripting the Owning Object

• Scripting Multiple Symbols

Slide 11

Important Note on ShowGraphic Function

• The ShowGraphic function can be used in a symbol’s action script, named script and pre-defined script. Although the system allows you to include it in a server script, such as Start Up, On Scan, OffScan, Shut Down and Execute, you will not be able to execute the function at run time.

• Detailed Examples are on Tech Note 815

Slide 12

Tag Viewer

• You can start Tag Viewer only if WindowViewer is running, and Tag Viewer has been enabled at design time.

• You can launch Tag Viewer from the WindowViewer menu or from a script calling the LaunchTagViewer() function.

• The above function can be executed from any script type, except application scripts: OnStartup and OnShutdown.

• If Tag Viewer is not enabled, calling the function will not start Tag Viewer and a warning message will be logged in the logger.

• You must have adequate security privileges to run Tag Viewer

Slide 13

Tag Viewer

Slide 14

WWHEAP Memory Settings

• You can configure the wwHeap Memory settings by specifying the wwHeap size and start location. The default size, default start location, and allowable location range vary by operating system.

• The default sizes are described in the following table:

Operating System Default Size

32 – bit 1519 MB

32 – bit with /3GB switch enabled

2048 MB

64 – bit 2048 MB

Slide 15

WWHEAP Memory Settings

• The default locations and allowable location ranges are described in the following table:

Operating System Default Start Location

Allowable Range

32 –bit 0x21000000 0x00010000 to0x7FFEFFFF

32-bit with the /3GBswitch enabled

0x40000000 0x00010000 to0xBFFEFFFF

64-bit 0x80000000 0x00010000 to0xFFFEFFFF

Slide 16

WWHEAP Memory Settings Example

Slide 17

Memory Caching for WindowViewer Windows

• You can configure how WindowViewer uses memory for Windows to improve performance at run time.

• Windows can be kept in memory at run time in certain conditions to allow for fast retrieval.

• You can also specify the interval for a periodic memory health check and settings for the heap memory segment.

Slide 18

Viewer Memory Caching

• In-Memory Window Caching• Memory Limit for In-Memory Windows

• The default memory limit is 70% of process memory.

• In-Memory Window Expiration Time

• The default value is 0 hours, which designates no time limit.

• You can enter a value between 0 and 8760 hours (365 days)

• High Priority Window Caching• Enable High Priority Window Caching

This allows some windows to be marked as high priority.

• Memory Limit for High Priority Windows

• The default memory limit is 90%.

Core Processor Affinity for WindowViewer

Slide 21

Lock Window Size

Slide 22

Expose Window Name Property

• GetWindowName script function enables the user to retrieve the name of the window under which the function has been called.

• The syntax of the script function is as follows:

Resultcode = GetWindowName(tagname);

• Resultcode indicates the success or failure of the script function. The resultcode can be a Discrete/Integer/Real data type.

• Resultcode will be 1 or 0, based on the success or failure of the script function: • Resultcode is 1 when the script function is called from window context.

• Resultcode is 0 when the script function is called from non-window context.

Slide 30

Issue 1: Tools/Techniques used in this SR

• Increase WWHeap – Must use GUI for InTouch 10.5 not the old Registry settings

• Process Explorer

• Log Viewer

• ArchestrA Symbol Analysis and Repair Tool for SP 2012 – not posted on WDN; has not helped any customers as far as we know; use older version of tool before migration to SP 2012

• Performance Monitor - Tech Note 868

• Event Viewer

• Galaxy Backup to view InTouch app

• Rebuild App with Tech Note 570

• Qslice

• Dump

Slide 31

Issue 1: Options to Create Dump

Is View frozen?

Slide 37

Issue 2: View freezes when Alarm occurs

Use WindowMaker File/Print to print all scripts to file

Caused by Application While Running Script

PlaySound( "C:\Windows\Media\Afternoon\Windows Notify.wav", 0 );

Slide 38

Issue 2: Print Scripts to File

Slide 39

Issue 3: Suitelink Suspends and Resumes

Usually caused by high CPU

One customer – due to PlaySound playing a wave file

One customer - caused by the aaflexlic dll for a hardware key

Issue 4: View crashes

Slide 41

Issue 4: Event Viewer for View Crash and Hang

Slide 42

Issue 4: View Crash Causes / Solutions

Cause #1: WWHeap conflict or Out of Memory. Look for WWHeap messages in Log Viewer or Event Viewer

Solution #1: Increase WWHeap Memory (Tech Note 768) or in Node Properties for InTouch 10.5

Cause #2: Not having the latest InTouch Service Pack and patch installed.

Cause #3: Running View on a non-supported OS / Service Pack.

Solution #3: Check the InTouch Readme for supported OS

Cause #4: View out of memory

Solution #4: Verify with Performance Monitor. Isolate to individual windows or window combinations

Slide 43

Issue 4: View Crash Causes / SolutionsCause #5: Scripting. Application While Running script causing resource

issue or an individual script causing a crash.

Solution #5: Isolate down to individual script. Print scripts to file for analysis.

Cause #6: View caused an invalid page fault in module CBTREENT.dll.

Solution #6: Corrupt InTouch History Files. Isolate to individual day causing the problem.

Cause #7: Corrupt window or InTouch App

Solution #7: Recompile the app OR rebuild the app (Tech Note 570 for Managed Apps, Tech Note 774 for Standalone apps)

Use Crash Dump if still unresolved

Issue 5: Handle Leaks

What can happen when there is a handle leak?

Slide 45

Issue 5: aaGR Handle Leak causes View Crash

• Various SP 2012 customers reporting View crash due to aaGR Handle Leak (34657 handles in one case)

• The scenario is that the ArchestrA Galaxy Repository is installed, but the node is just being used as an InTouch Runtime.

• Hotfix CR L00121244

• Number of Handles used by process. Seen with Task Manager, Process Explorer or Wonderware Tech Support Info Tool

• Demo of Wonderware Tech Support Info Tool and Performance Monitor in session “TSS 10 – WAS Advanced Troubleshooting”
