NW2004s SR2 installation

[Former Member]

Hi,

I am planning the installation of NW2004s on a distributed environment on AIX. I have gone through the installation guide and a bit confused about installing them on multiple hosts. Here is what I have planned and this is for BI 7.0.

1. Database on multiple nodes. I will be using DB2 DPF functionality.

2. 4 AIX application servers.

Q1. The install guide, talks about /sapmnt being mounted from SAP Global host and /usr/sap/<SAPSID> being local. If I understand this correctly, we will first install the first host, which is the SAP Global host, and I plan on installing both Central Instance and Central Services instance on the same host. Then, export the /sapmnt from this host and mount them on all other hosts, then install SAP (dialog instances) on all the remaining three hosts and the /usr/sap will be local on each host, including the first one. During the installation, sapinst will link some files from /usr/sap to /sapmnt/<SAPSID>. Is this correct ?

Q2. When SAP is talking about database instance, is there anything that is required to be installed from SAP side on the database host. In my case, we planned a set of dedicated nodes for the database and planned on installing only the DB2 UDB on this. During the installation of the first host, global, we will specify the host name of the database. Is this correct ?

Any help here is appreciated.

Thanks

Hello,

Q1: Yes, it's correct. The dialog instances must have a connection to the exported /sapmnt/<SID> mount point from the SCS instance to create and read their profiles.

You have to specify the path to it during the installation.

Q2: During the installation of the SCS instance you will be asked for the DB host. The other instances will read this information from the created SCS profiles in the /sapmnt/<SID> directory.

The DB installation should be a "clean" one without any manually created instance(s) - SAPInst will do it for you. Also you should check the Product Availability Matrix to find out which DB version is supported by SAP --> link to the PAM

Good luck.
