SHOW GCT

Displays the contents of the Galaxy configuration tree either in summary (hierarchical) or in detail, node by node.

Format

SHOW GCT [/ADDRESS=n]|[/ALL]|[CHILDREN]|
|[/HANDLE=n]|[/OWNER=n]|[/SUMMARY (default)] |[/TYPE=n]

Parameters

None.

Qualifiers

/ADDRESS=n

Provides a detailed display of the Galaxy configuration tree (GCT) node at the given address.

/ALL

Provides a detailed display of all nodes in the tree.

/CHILDREN

When used with /ADDRESS=n or /HANDLE=n, the /CHILDREN qualifier causes SDA to display all nodes in the configuration tree that are children of the specified node.

/HANDLE=n

Provides a detailed display of the Galaxy configuration tree (GCT) node with the given handle.

/OWNER=n

Provides a detailed display of all nodes in the tree currently owned by the node with the given handle.

/SUMMARY

Provides a summary display of the Galaxy configuration tree (GCT) in hierarchical form. This qualifier is the default.

/TYPE=type

Provides a detailed display of all nodes in the tree of the given type, which can be one of the following:
BUS CAB COMMUNITY CPU
CPU_MODULE EXP_CHASSIS FRU_DESC FRU_ROOT
HARD_PARTITION HOSE HW_ROOT IO_CTRL
IOP MEMORY_CTRL MEMORY_DESC MEMORY_SUB
PARTITION POWER_ENVIR PSEUDO RISER
ROOT SBB SLOT SMB
SW_ROOT SYS_CHASSIS SYS_INTER_SWITCH TEMPLATE_ROOT

The type given may be an exact match, in which case just that type is displayed (for example, a CPU); or a partial match, in which case all matching types are displayed (for example, /TYPE=CP displays both CPU and CPU_MODULE nodes).

Examples

This command shows the summary (hierarchical) display of the configuration tree.

SHOW GLOBAL_SECTION_TABLE, SHOW GST

Displays information contained in the global section table.

Format

SHOW GLOBAL_SECTION_TABLE or SHOW GST [/SECTION_INDEX=n]

Parameters

None.

Qualifiers

/SECTION_INDEX=n

Displays only the global section table entry for the specified section.

Description

Displays the entire contents of the global section table, unless you specify the qualifier /SECTION_INDEX. This command is equivalent to SHOW PROCESS/PROCESS_SECTION_TABLE/SYSTEM. See the SHOW PROCESS command and Table 4-18 for more information.

Example

SHOW GLOCK

Displays the Galaxy locks for the Galaxy Management Database (GMDB), process tables, and/or system tables.

Format

SHOW GLOCK [/BRIEF]
[/GMDB_TABLE]
[/PROCESS_TABLE [=n]]
[/SYSTEM_TABLE [=n]]
[/ALL]
[/ADDRESS=n [/PHYSICAL]]
[/HANDLE=n [/LINKED]]

Parameters

None.

Qualifiers

/BRIEF

Displays a single line for each Galaxy lock, regardless of any other qualifiers.

/GMDB_TABLE

Displays the Galaxy lock table for the Galaxy Management Database (GMDB) including the embedded and attached Galaxy locks.

/PROCESS_TABLE [=n]

Displays all the process Galaxy lock tables with the embedded and attached Galaxy locks, as well as a summary table. The /PROCESS_TABLE=n qualifier displays the single Galaxy lock table without a summary page.

/SYSTEM_TABLE [=n]

Displays all the system Galaxy lock tables with the embedded and attached Galaxy locks, as well as a summary table. The /SYSTEM_TABLE=n qualifier displays the single Galaxy lock table without a summary page.

/ALL

Displays information provided by the /GMDB_TABLE, /PROCESS_TABLE, and /SYSTEM_TABLE qualifiers. The /ALL qualifier also displays information from the base GMDB Galaxy lock.

/ADDRESS=n [/PHYSICAL]

Displays the single Galaxy lock at address n. Because process Galaxy locks are located by their physical address, you must use the /PHYSICAL qualifier to enter such an address.

/HANDLE=n [/LINKED]

Displays the single Galaxy lock whose handle is n. The optional qualifier /LINKED causes SDA to display all Galaxy locks linked to the one specified.

None.

Qualifiers

/ADDRESS

Specifies the address of a single node block to be displayed when used with the /NODE qualifier. See the description of the /NODE qualifier.

/ALL

Displays the contents of the Galaxy Management Database and all node blocks that have ever been used (contents nonzero).

/NODE [=name|=n|/ADDRESS=n]

Displays the contents of the specified node block, given by either the name of the instance, the partition number, or the address of the node block. If the /NODE qualifier is given alone, then the node block for the current instance is displayed.

SHOW GSD

Displays information contained in the global section descriptors.

Format

SHOW GSD [/ADDRESS=n|/ALL|/DELETED|/GLXGRP
|/GLXSYS|/GROUP|/SYSTEM]

Parameters

None.

Qualifiers

/ADDRESS=n

Displays a specific global section descriptor entry, given its address.

/ALL

Displays information in all the global section descriptors, that is, the system, group, and deleted global section descriptors, plus the Galaxy group and Galaxy system global section descriptors, if the system or dump being analyzed is a member of an OpenVMS Galaxy system. This qualifier is the default.

/DELETED

Displays information in the deleted (that is, delete pending) global section descriptors.

/GLXGRP

Displays information in the group global section descriptors of a Galaxy system.

/GLXSYS

Displays information in the system global section descriptors of a Galaxy system.

/GROUP

Displays information in the group global section descriptors.

/SYSTEM

Displays information in the system global section descriptors.

Description

The SHOW GSD command displays information that resides in the global section descriptors. Table 4-3 shows the fields and their meaning.

Table 4-3 GSD Fields
Field Meaning
ADDRESS Gives the address of the global section descriptor
NAME Gives the name of the global section
GSTX Gives the global section table index
FLAGS Gives the settings of flags for specified global section, as a hexadecimal number; also displays key flag bits by name
BASEPFN 1 Gives physical page frame number at which the section starts
PAGES 1 Gives number of pages (not pagelets) in section
REFCNT 1 Gives number of times this global section is mapped
1This field only applies to PFN mapped global sections.

Example

SHOW HEADER

Displays the header of the dump file.

Format

SHOW HEADER

Parameters

None.

Qualifiers

None.

Description

The SHOW HEADER command produces a 10-column display, each line of which displays both the hexadecimal and ASCII representation of the contents of the dump file header in 32-byte intervals. Thus, the first eight columns, when read right to left, represent the hexadecimal contents of 32 bytes of the header; the ninth column, when read left to right, records the ASCII equivalent of the contents. (Note that the period [.] in this column indicates an ASCII character that cannot be displayed.)

After it displays the contents of the header blocks, the SHOW HEADER command displays the hexadecimal contents of the saved error log buffers.

See the OpenVMS AXP Internals and Data Structures manual for a discussion of the information contained in the dump file header. See also the SHOW DUMP and CLUE ERRLOG commands, which can be used to obtain formatted displays of the dump header and error log buffers.

Example

The SHOW HEADER command displays the contents of the dump file's header. Ellipses indicate hexadecimal information omitted from the display.
