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.






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).




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.

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.
