HP OpenVMS Systems Documentation

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. (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 you can use to obtain formatted displays of the dump header and error log buffers.

See also the SHOW DUMP command, which will output a formatted display of the contents of the dump header.

Example

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

Displays information about an image, regardless of the type of image (executive, activated, or installed).

Format

SHOW IMAGE image-name

Parameters

image-name

Name of the image to be displayed. This is a required parameter that may include wildcards.

Qualifiers

None.

Description

Searches the executive image list for the image name, and, if a match is found, displays the loaded image information. Next, searches the activated image list for the process (if SDA has a current process context). If a match is found, displays the activated image information. Finally, searches the installed image lists, directory by directory. If a match is found, displays the installed image (known file entry) information.

SHOW IMAGE x is equivalent to SHOW EXECUTIVE x followed by SHOW PROCESS/IMAGE=x followed by SHOW KFE x .

This example shows the output from SHOW IMAGE for SYS$PUBLIC_VECTORS. Part of the example has been moved left to stay within page boundaries of the manual.

Displays information about known file entries (installed images).

Format

SHOW KFE [image_name | /ADDRESS=kfe_address | /ALL]

SHOW KNOWN_FILE_ENTRY [image_name | /ADDRESS=kfe_address | /ALL]

Parameters

image-name

Name of the image to be displayed. This may include wildcards, but cannot include device or directory information.

Qualifiers

/ADDRESS=kfe_address

Specifies the address of a single KFE of interest. The details are displayed for this KFE with device/directory information from the corresponding KFD (Known File Directory).

/ALL

Displays details for all KFEs, including device/directory information from the corresponding KFDs, with the contents of the Known File Pointer Block (KFPB).

Description

The SHOW KFE command displays information about known files (installed images). By default, a summary line without image-section information is given for each image. Use the /ALL qualifier to obtain detailed information for all images. For a single image, specify the image name or KFE address.

The image_name parameter, the /ADDRESS, and /ALL qualifiers cannot be used together. SHOW KNOWN_FILE_ENTRY is a synonym for SHOW KFE.
