SAP on DB2 for Windows MSCS - HA Cluster Installation

87 Views

HI Gurus,

I have to install SAP ECC EHP6 for DB2 10.1 and Windows 2008 R2 combination in HA cluster.

I have done SAP HA installation before but all were for Windows/SQL so I am familiar with ASCS, SCS, Database, primary and additional instance installation.

This is the first time I am going to install DB2 as database in HA MSCS environment.

I have gone through the installation guide 2-3 time and have few queries, any explanation will be highly welcomed :

1. DB2 has to be installed on both the nodes using the software dump provided by SAP before starting SAP installation ?

2. Installation guide says db2mscs utility is used to cluster the database. Will it be run before ASCS and SCS installation ?

3. DB2mscs file creates resources under DBGRP in failover cluster automatically ? or they are suppose to be created manually ?

3. Normally before installation I used to ask OS/Cluster guy to create 3 groups - CLSTGRP, SAPGRP, DBGRP

Will DB2mscs create these groups or will I need to ask OS guy to create these manually before installation ?

You may suggest and share your experiences also, which will prove handy for my installation. Though at this time i just have installation guide to stick to and nothing else.

Thanks,

SG
