CHAPTER 2 Starting and Stopping Servers

kill pid

where pid is the process identification of any dataserver or backupserver process, as determined by the showserver command. Killing one engine for a particular Adaptive Server kills all engines for that server.

If more than one Adaptive Server is running on the same system, be careful that the engine you kill is associated with the correct Adaptive Server. If your Adaptive Server is configured to use multiple engines (CPUs), each engine has an associated operating system process. The correct way to kill a multi-engine server is to specify the process ID for engine 0.

This showserver output shows the processes for a four-engine server:

showserver

UID	PID	PPID	C	STIME	TTY	TIME	COMD
jorge	3320	1	80	10:31:40	pts/4	302:15	dataserver -dteamster
jorge	3321 3320		80	10:31:45	pts/4	324:47	dataserver -ONLINE:1
jorge	3322 3320		80	10:31:45	pts/4	326:02	dataserver -ONLINE:2
jorge	3323 3320		80	10:31:45	pts/4	328:56	dataserver -ONLINE:3

This example shows four running dataserver processes with operating system process identifications (PID) 3320, 3321, 3322, and 3323 (dataserver is the executable form of the Adaptive Server program.)

Child engine processes for the dataserver have the -ONLINE:argument.

Each child engine has a parent process identification (PPID) that is equal to the process identification (PID) of the parent. In the example above, the PID of the parent server is 3320. The other three engines spawned by the parent process have the same PPID.

If the PPIDs appear to be unrelated, and there is more than one dataserver process, then more than one Adaptive Server is running on the system.

Shutdown and shared memory files

When Adaptive Server starts, it creates SERVER_NAME.krg file in

$SYBASE/$SYBASE_ASE directory to store information about shared memory segments that it uses.
