MSCS and Kernel patches: Can someone please refresh my memory?

[Former Member]

Greetings,

We run 4.7 Ent on a 2-node MSCS Cluster (SQL).

I need to do a kernel upgrade, but I have forgotten the precise distribution of kernel files outside of the "run" directory for the cluster.

I understand they are:

Main Kernel Files

shared_drive \usr\sap\<SID>\SYS\exe\run

MSCS Files (on each node)

local_drive \Windows\SapCluster\

local_drive \Windows\System32\

However, could someone please remind me which files go into

"SapCluster" and "System32", or if you know the location, point me to an SAP document that details the kernel patch process in an MSCS Cluster (rather than a general MSCS config document which is of no use in this situatio).

Thanks if anyone is able to help.

Hi Tim,

We have a productive SAP R/3 4.7 (Windows 2003 IA64 Oracle 9.2) on a 2 nodes MSCS cluster.

In C:\windows\SapCluster

We have the following files :

backint.exe

brarchive.exe

brbackup.exe

brconnect.exe

brgui

brrecover.exe

brrestore.exe

brspace.exe

brtools.exe

cpio.exe

cpqccms.dll

dd.exe

dev_rout

mkszip.exe

mt.exe

niping.exe

pstat.exe

rfcoscol.exe

routtab.txt

sapevents.dll

sapgw

sapntchk.exe

sapntwaitforhalt.exe

saposcol.exe

saprouter.exe

sapsrvkill.exe

sapstart.exe

sapstartsrv.exe

sapstartsrv.exe.new

sapxpg.exe

uncompress.exe

So basically the SAP cluster dlls and the brtools.

We have also C:\windows\SapCluster\brgui with the brgui files

and C:\windows\SapCluster\sapgw with the standalone gateway executables

In C:\windows\system32 we have these SAP files :

sapmmc.dll

sapmmcada.dll

sapmmcinf.dll

sapmmcms.dll

saprc.dll

saprcex.dll

sapstart.log

sapstartsrv.exe

To update the kernel, we do it one node after the other one switching the SAP resources between the 2 nodes .

We of course keep the same patch level in the different directories.

Hope this helps.
