HP OpenVMS Systems Documentation

Displays the current default values for the multiblock count, the multibuffer count, the network transfer size, the prolog level, the extend quantity, and the query lock option.

Format

SHOW RMS_DEFAULT

Parameters

None.

Description

The SHOW RMS_DEFAULT command displays information that OpenVMS Record Management Services (RMS) uses for file operations including the default values for the multibuffer count, the multiblock count, the network block count, the prolog level, the extend quantity, and the query lock option. The command provides these values at both the current process level and at the system level.

The SHOW RMS_DEFAULT command lists the multibuffer count values for each of the file types, including the values for the three classes of sequential files (disk, magtape and unit record).

Qualifier

/OUTPUT[=filespec]

/NOOUTPUT

Specifies the file to which the display is written (default is SYS$OUTPUT). The asterisk (*) and the percent sign (%) wildcard characters are not allowed in the file specification. If you enter the /OUTPUT qualifier with a partial file specification (for example, specifying only a directory), SHOW is the default output file name and .LIS the default output file type.

If you enter the /NOOUTPUT qualifier, output is suppressed.

Example

$ SHOW RMS_DEFAULT
        MULTI- |               MULTIBUFFER COUNTS            | NETWORK
        BLOCK  | Indexed Relative         Sequential         | BLOCK

System   16    |    0        0      0      0         0       |   8
         Prolog    Extend Quantity      VCC_DFW     QUERY_LOCK
Process    0              0                0        System

The SHOW RMS_DEFAULT command in this example shows a system multiblock count of 16 and a network block count of 8. These are typical values. Note that the placeholder, VCC_DFW, is currently reserved for use by HP.

Displays the current value of the system root and, if defined, the process root.

Format

SHOW ROOT

Example

$  SHOW ROOT
DISK1:[000000]
$  SET ROOT DISK5:[ PSX$ROOT]
 
$ SHOW ROOT
DISK5:[ PSX$ROOT]
$
      

The SHOW ROOT command in this example displays the current root path. The SET ROOT command changes these defaults, and the next SHOW ROOT command displays the new default root.
