This display shows the detailed information on the SCHED spinlock, including the PC history.

SHOW STACK

Displays the location and contents of the process stacks (of the SDA current process) and the system stack.

Format

SHOW STACK {range|/ALL|[/EXECUTIVE|/INTERRUPT|/KERNEL |/PHYSICAL|/SUMMARY| /SUPERVISOR|/SYSTEM|/USER]} {/LONG|/QUAD (d)}

Parameter

range
Range of memory locations you want to display in stack format. You can express a range using the following syntax:

m:n Range of addresses from m to n

m;n Range of addresses starting at m and continuing for n bytes

Qualifiers

/ALL
Displays the locations and contents of the four process stacks for the SDA current process and the system stack.
/EXECUTIVE
Shows the executive stack for the SDA current process.
/INTERRUPT
Shows the system stack and is retained for compatibility with OpenVMS VAX. The interrupt stack does not exist in OpenVMS Alpha.
/KERNEL
Shows the kernel stack for the SDA current process.
/LONG
Displays longword width stacks. If you do not specify this qualifier, SDA by default displays quadword width stacks.
/PHYSICAL
Treats the start and end addresses in the given range as physical addresses. This qualifier is only relevant when a range is specified. By default, SDA treats range addresses as virtual addresses.
/QUAD
Displays quadword width stacks. This is the default.
/SUMMARY
Displays a list of all known stack ranges and the current stack pointer for each range.
/SUPERVISOR
Shows the supervisor stack for the SDA current process.
/SYSTEM
Shows the system stack.
/USER
Shows the user stack for the SDA current process.

Description

The SHOW STACK command, by default, displays the stack that was in use when the system failed, or, in the analysis of a running system, the current operating stack. For a process that became the SDA current process as the result of a SET PROCESS command, the SHOW STACK command by default shows its current operating stack.
The various qualifiers to the command allow display of any of the four per-process stacks for the SDA current process, as well as the system stack for the SDA current CPU. In addition, any given range can be displayed in stack format.
You can define SDA process and CPU context by using the SET CPU, SHOW CPU, SHOW CRASH, SET PROCESS, and SHOW PROCESS commands as indicated in their command descriptions. A complete discussion of SDA context control appears in Section 2.5.
SDA provides the following information in each stack display:

Section Contents

Identity of stack SDA indicates whether the stack is a process stack (user, supervisor, executive, or kernel) or the system stack.

Stack pointer The stack pointer identifies the top of the stack. The display indicates the stack pointer by the symbol SP =>.

Stack address SDA lists all the addresses that the operating system has allocated to the stack. The stack addresses are listed in a column that increases in increments of 8 bytes (one quadword) unless you specify the /LONG qualifier, in which case addresses are listed in increments of 4 (one longword).

Stack contents SDA lists the contents of the stack in a column to the right of the stack addresses.

Symbols SDA attempts to display the contents of a location symbolically, using a symbol and an offset.
If the stack is being displayed in quadword width and the location cannot be symbolized as a quadword, SDA attempts to symbolize the least significant longword and then the most significant longword. If the address cannot be symbolized, this column is left blank.

Canonical stack When displaying the kernel stack of a noncurrent process in a crash dump, SDA identifies the stack locations used by the scheduler to store the register contents of the process.

Mechanism array
Signal array
Exception frame When displaying the current stack in a FATALEXCPT, INVEXCEPTN, SSRVEXCEPT, or UNXSIGNAL bugcheck, SDA identifies the stack locations used to store registers and other key data for these structures.

If a stack is empty, the display shows the following:
SP => (STACK IS EMPTY)

This example shows the stack ranges for a process on an OpenVMS I64 system.

SHOW SUMMARY

Displays a list of all active processes and the values of the parameters used in swapping and scheduling these processes.

Format

SHOW SUMMARY [/IMAGE|/PROCESS_NAME=process_name
|/THREAD|/USER=username]

Parameters

None.

Qualifiers

/IMAGE
Causes SDA to display, if possible, the name of the image being executed within each process.
/PROCESS_NAME=process_name
Displays only processes with the specified process name. You can use wildcards in process_name, in which case SDA displays all matching processes. The default action is for SDA to display data for all processes, regardless of process name.
/THREAD
Displays information on all the current threads associated with the current process.
/USER=username
Displays only the processes of the specified user. You can use wildcards in username, in which case SDA displays processes of all matching users. The default action is for SDA to display data for all processes, regardless of user name.

Description

The SHOW SUMMARY command displays the information in Table 4-29 for each active process in the system.

Table 4-29 Process Information in the SHOW SUMMARY Display
Column Contents

Extended PID The 32-bit number that uniquely identifies the process or thread.

Indx Index of this process into the PCB array. When SHOW SUMMARY/THREAD is used, for all threads of a process other than the initial thread, displays the thread number.

Username ¹ Name of the user who created the process.

State Current state of the process. Table 4-30 shows the 14 states and their meanings.
