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

None.
Qualifiers
/ADDRESS=n
Displays 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.

When used with /CHILDREN, /OWNER=n, or /TYPE=type, the /FULL qualifier
causes SDA to provide a detailed display of each node.

with the given handle.
/OWNER=n
Displays all nodes in the tree currently owned by the node with the
given handle.

SHOW GLOBAL_SECTION_TABLE
Displays information contained in the global section table, including
pageable sections of loadable images. Functionally equivalent to SHOW
GST.

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. SDA displays the information
in Table 4-5 for each GST entry.

|
Address of the global section table entry.
|
|
SECT/GPTE
|

section described by this entry, if a loadable image; or the virtual
address of the global page table entry for the first page, if a global
section.
|
|
GSD
|
Address of the corresponding Global Section Descriptor. This field is
zero for loadable images.
|
|

Example
SHOW GLOCK
Displays the Galaxy locks for the Galaxy Management Database (GMDB),
process tables, and/or system tables.
Format
SHOW GLOCK [/ADDRESS=n [/PHYSICAL]
| /ALL
| /GMDB_TABLE
| /HANDLE=n [/LINKED]
| /PROCESS_TABLE [=n ]
| /SYSTEM_TABLE
[=n ]]
[/BRIEF]
Parameters
None.
Qualifiers
/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.
/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.
/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.
