SAPCPE

[Bruno Bossier_1]

Hi,

I have a SAP installation which I'm going to configure into a 2-node ServiceGuard cluster. There are no application servers.

Is SAPCPE required ? According to the SGeSAP installion guide it is, but I wonder if that is really the case.

Cheers,
Bruno

As long as:
01. both nodes are same/compatible and enough to handle load and swap/memeory is configured right,
uid/gid/services/kernel parameters are properly configured
oracle client is present on both machine if being used locally
Service guard is configured properly to mount everything(package config,lan config,/etc/hosts file etc)
02. You store the binaries in shared VG
03. you install SAP license for both machines(very important), so that when it moves to secondary node, it does not copmplain about the license
04. your sap sidadm profiles are properly configured depending on hostnames.
05. startsap is properly configured.
06. default and INSTANCE profiles are properly configured
07. sapcpe is used to sync / update the app servers executable files from central instance. You do not have any app server.

you should be good to go. You should not need sapcpe.

Also, If you are going to use standby node as app server then you should have the instance number different than the DB server to have the runtime data of sap instance separate and is usefull when failing over to standby node.

read the sap extension for MCSG for detail if you are planning to have secondary node as app server.

Many things of sap extension for SAP manual can be avoided. Do not necessarily need the SAP extension for MCSG. just write your own scripts and run them when failing over to standby node.

We're definitely never going to have any application servers runnning. All uid's, gid"s, /etc/hosts, ... are all the same between the 2 nodes, so I think I should be safe.

Thanks for the feedback !
