systemCheck

 

 

Description

The systemCheck function performs a system diagnostic check of the current memory manager and displays a system error message if any memory blocks are damaged and cannot be repaired. If there are no arguments, the systemCheck function displays the low-level memory manager allocations according to frame size and displays some basic statistics on memory usage. If there is a single argument, and it is false, then the systemCheck function does NOT display memory statistics on the console. If there is a second argument, and it is boolean (true or false), then the Analytic Information System engine system-self-check-mode is set on (true) or off (false). In system-self-check-mode, a system check is performed a frequent intervals. This greatly reduces execution speed; but, is useful in tracking sown elusive error conditions.

When to use

Use the systemCheck function to perform a system diagnostic check and to view the memory usage of the Analytic Information Server System. The systemCheck function is useful for determining if there are memory leaks. As a debugging aid, the systemCheck function is useful also to determine if invalid or damaged objects are created by the Analytic Information Server System.

 

Syntax

(systemCheck)

(systemCheck displaySW)

(systemCheck displaySW selfCheckSW)


Name Description AIS Types
displaySW (Optional) A boolean argument which, if missing or true, causes memory block statistics to be displayed on the AIS console during system self check. Boolean
selfCheckSW (Optional) A boolean argument which causes the Analytic Information System engine system-self-check-mode is be set on (true) or off (false). Boolean

Returns:

The Boolean value, true.

 

Examples

Here are a number of links to Lambda coding examples which contain this instruction in various use cases.

Example_Context_systemCheck_001

This example uses the saveWorkspace function to perform a system diagnostic check and to view the memory usage of the Analytic Information Server System.
