Slide 4 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: Microsoft Cryptographic services will be leveraged to read certificates that are stored in the smart card. Refer to following link for details:

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 = " "; graphicInfo.GraphicName = " "; 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 symbols 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 SystemDefault Size 32 – bit1519 MB 32 – bit with /3GB switch enabled 2048 MB 64 – bit2048 MB
Slide 15 WWHEAP Memory Settings The default locations and allowable location ranges are described in the following table: Operating SystemDefault Start Location Allowable Range 32 –bit0x x to 0x7FFEFFFF 32-bit with the /3GB switch enabled 0x x to 0xBFFEFFFF 64-bit0x x to 0xFFFEFFFF
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%.

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 23 Advanced Troubleshooting Techniques
