Stopping ASCS while EHP4 upgrade

[Former Member]

Hi,

Dear all, i am in a process of upgrading ecc6.0 to EHP4 in High Availability , OS is Solaris,

After reaching the phase downtime , SAP asked us to stop the ASCS Instance.

pls see the msg below.

"You are running a so-called High-availibility setup.

To enter the downtime it is necassary to stop the

ASCS instance manually on the remote host.

In addition also the sapstartsrv and saposcol processes

on the remote host must be stopped."

if i understand correctly ASCS is the Central Instance under High Availability.

pls let me know is it mandatory to stop this and also its is asking me to stop sapstartsrv and saposcol.

pls let me know the procedure to stop all these 3.

Thank you.

Yes , it is must to stop ASCS as well for upgrade .For stopping you can follow normal process to stop ..Normally we will use cluster tool only to avoid switch over (If you will do using MMC) ..Stop ASCS and then you can stop saposcol using

saposcol -k

for sapstartsrv i guess this comand will help

sapcontrol -nr <instancenumber> -function StopService

Hi,,

Thanks for your response..

In profile directory i could see 2 files associated with ASCS they are.

PRD_ASCS00_eccprd

START_ASCS00_eccprd

so, the command to stop ASCS would be

stopsap ASCS00

PLEASE VERIFY..

Thanks

Hi,

stopsap r3 ASCS<nn> <virtual host name> in your case it's stopsap r3 ASCS00 eccprd ( also use -v for virtual hostname before eccprd)

or in case of seperately hosted ASCS execute => stopsap r3 <virtualhost> i.e stopsap r3 eccprd - this will stop instances in sequence order check ps -ef | grep ms.sap<SID_ASCS00>

Hi,

You have to Stop Central instance / Dialog instance first then Central services.

ASCS00 is called as Central services.

DVEBMGS04 is called as Central instance

In you case your are stopping first central services and then central instance. which is not physible.

Thanks
