The Debugging Attributes of a Process

Each process has two debugging attributes, INSPECT and SAVEABEND. The

software sets the values of these attributes for a process when it starts the process.

The Inspect attribute determines which debugging tool (Inspect or Debug) to use for

the process.

Specifically, on a TNS/R system, these debugger selection rules apply:

The SAVEABEND attribute controls whether a save file is created automatically if the

process abends, and the SAVEABEND attribute interacts with the INSPECT attribute.

Specifically, on a TNS/R system, these rules apply for the SAVEABEND attribute:

For more information about debugger selection and debugging attributes on a TNS/E

system see Section 18, Using Inspect on a TNS/E System.

The system software sets the debugging attributes of a process when it starts the

process. To select the proper values, the operating system compares these three sets

of attribute values:



The attribute values found in the program file.



The attribute values of the creator of the process.



The attribute values specified in the call that creates the process. TACL specific

attribute values exist when the process is created based on the TACL SET

INSPECT command and the run line.

INSPECT

Attribute Meaning

INSPECT ON Selects either Inspect or Visual Inspect as the debugging tool for the

process.

To use Visual Inspect, you must have a client connection set up before

the debugger is invoked.

If neither Visual Inspect nor Inspect is available, Debug is selected as

the debugger of last resort.

Only Visual Inspect (not Inspect) can be used to debug TNS/R native

position-independent code (PIC) program files.

INSPECT OFF Selects Debug as the debugging tool for the process.

SAVEABEND

Attribute Meaning

SAVEABEND ON Specifies that a save file should be created if the process abends.

Setting SAVEABEND ON also sets INSPECT ON.

SAVEABEND OFF Specifies that a save file should not be created if the process abends.
