Determining Whether a Server Is Running
Checking Servers in the Guardian Environment That Are Not
Administered Through the OSS Monitor
To determine whether such a server is running, you use the basic SCF LISTDEV
command. (There is no OSS Monitor command to provide this information.)
Here is an example: Suppose you want to determine whether a transport-provider
process for OSS AF_INET sockets is running. The transport provider is the $ZTCn
server, described under OSS Sockets on page 1-14.
If you enter the LISTDEV command at an SCF prompt, a display similar to that shown
in Figure 4-6 on page 4-37 appears. In the figure, the transport-provider process
$ZTC0 is shown as:
•
Running, with:
°
Its primary process in processor 1 at PIN 47
°
Its backup process in processor 0 at PIN 63
•
Having a:
°
Logical device number of 228
°
Device type of 48
°
Device subtype of 0
°
Scheduling priority of 180
•
Using the object file \NODE1.$SYSTEM.SYS00.TCPIP
$ZTC0 is the only transport provider running, because it is the only process displayed
with a name of that form. Other servers used by OSS processes and by the OSS
subsystem also appear in Figure 4-6.
