Stopping a Sink Machine Using HLI Control Commands

HLI control commands can shut down the sink machine from one of the source machines. The syntax for control commands is

CALL FOCUS ('HLI ',fcb) 

where:

fcb

Is the File Communication Block.

Prepare the FCB as follows:

• Place the subcommand to be executed in the first 8 bytes of the FCB (replaces filename in FCB words 1 and 2). These subcommands are:

STOPSINK

Causes the sink machine to execute any pending requests in queue, to close all files, and to return to CMS.

HX

Terminates the sink machine abnormally and returns to CMS. Use only in an emergency, because it may leave files vulnerable to damage.

• Place the value SU in FCB word 6 (SU with two trailing blanks).
• Place the user ID of the sink machine you intend to shut down in FCB words 9 and 10.
• Place the control password, entered at the time the sink machine was started (described in Operating the Sink Machine), in FCB words 19 and 20
