SAP Processes after system shutdown

722 Views

Hi

We have following processes running after shutting down sap instance with distributed installation (1 Central Instance + One database)

root  9109610        1   0   Jan 11      -  0:04 /usr/sap/hostctrl/exe/saphostexec pf=/usr/sap/hostctrl/exe/host_profile 
  sapadm  9240678        1   0   Jan 11      -  0:28 /usr/sap/hostctrl/exe/sapstartsrv pf=/usr/sap/hostctrl/exe/host_profile -D 
    root  9764916        1   0   Jan 11      -  0:23 /usr/sap/hostctrl/exe/saposcol -l -w60 pf=/usr/sap/hostctrl/exe/host_profile 
  <sapsid>adm  9830494        1   1   Jan 12      -  0:45 /usr/sap/<SAPSID>/J00/exe/sapstartsrv pf=/usr/sap/<SAPSID>/SYS/profile/<SAPSID>_J00_<HOSTNAME> -D -u <sapsid>adm 
  <diagsid>adm 10027180        1   0   Jan 14      -  0:01 /usr/sap/<DIAGSID>/SMDA97/exe/sapstartsrv pf=/usr/sap/<DIAGSID>/SYS/profile/<DIAGSID>_SMDA97_<HOSTNAME> -D -u <diagsid>adm 
  <diagsid>adm 10092686 10223810   0   Jan 14      -  2:53 /usr/sap/<DIAGSID>/SMDA97/exe/jstart -appTrc -nodeId=0 pf=/usr/sap/<DIAGSID>/SYS/profile/<DIAGSID>_SMDA97_<HOSTNAME> -hostvm -nodeName=smdagent -file=/usr/sap/<DIAGSID>/SMDA97/SMDAgent/smdagent.properties -jvmFile=/usr/sap/<DIAGSID>/SMDA97/work/jstart.jvm -traceFile=/usr/sap/<DIAGSID>/SMDA97/work/dev_smdagent -javaOutFile=/usr/sap/<DIAGSID>/SMDA97/work/jvm_smdagent.out 
  <diagsid>adm 10223810 10616894   0   Jan 14      -  0:00 jc.sap<DIAGSID>_SMDA97 pf=/usr/sap/<DIAGSID>/SYS/profile/<DIAGSID>_SMDA97_<HOSTNAME> 
  <diagsid>adm 10616894        1   0   Jan 14      -  0:00 sapstart pf=/usr/sap/<DIAGSID>/SYS/profile/<DIAGSID>_SMDA97_<HOSTNAME>

Can someone help to find why there are so many processes esp sapstart , jstart, sapstartsrv for diag agent and instance? Do we need to stop each of these processes every time we shut down the instance ? and start them again manually ?

Thanks,
