n is either 1 (true) or 0 (false). The default value is 0.
When NodeNameInPid is enabled (n = 1), $JOB returns the process ID number of the current process concatenated to the node name. When NodeNameInPid is not enabled, $JOB returns only the process ID number, without the node name.
Changing This Parameter
On the Compatibility page of the Management Portal (System Administration > Configuration > Additional Settings > Compatibility), in the NodeNameInPid row, click Edit. Select NodeNameInPid to enable this setting.
Instead of using the Management Portal, you can change NodeNameInPid in the Config.MiscellanousOpens in a new window class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
To change this parameter for a single process only (as opposed to instance-wide), use the NodeNameInPid()Opens in a new window method of the %SYSTEM.ProcessOpens in a new window class. See the class reference for details.
