第八章 Caché 變數大全 $JOB 變數

包含當前程序的ID。

大綱

$JOB
$J

描述

$JOB包含當前程序的ID號。該ID號是主機作業系統的實際程序ID（PID）。該ID號對於每個程序都是唯一的。

返回的$JOB字串的格式由％SYSTEM.Process類的NodeNameInPid（）方法的設定確定，用於當前程序。可以通過設定Config.Miscellaneous類的NodeNameInPid

不能使用SET命令修改此特殊變數。嘗試這樣做會導致<SYNTAX>錯誤。

要將PID建立為終端提示，請使用%SYSTEM.Process類的TerminalPrompt(5)方法。

有關當前程序的其他資訊

可以通過呼叫ProcessId()方法獲得相同的當前程序ID號，如下所示：

DHC-APP>WRITE $SYSTEM.SYS.ProcessID()
22384

可以使用$JOB獲取當前程序的JOB編號，如下所示：

DHC-APP>SET JobObj=##CLASS(%SYS.ProcessQuery).%OpenId($JOB)
 
DHC-APP>WRITE JobObj.JobNumber
20
DHC-APP>zw JobObj
JobObj=<OBJECT REFERENCE>[1@%SYS.ProcessQuery]

可以從$ZJOB特殊變數獲取有關當前程序的狀態資訊。

可以從$ZCHILD和$ZPARENT特殊變數中獲得當前程序的子程序或父程序的PID。

可以從^$JOB結構化系統變數獲取JOB表中當前作業的PID。
