Hello Bjoern,

Installing a CI (or primary app. server)  on a Linux box against DB2 for IBM i is not supported.

Only CI installed on IBM i is supported. You can however install mulitple Linux or WIndows dialog systems (or secondary app servers). You can manage then the appropriate load on each server.

Many logistic operations like exports and upgrades though will always have to be ran on the CI.

Hi Bjoern,

Little bit confussion about 'i' at the end of IBM DB2. I thought you asked about "DB6" - IBM DB2 for Linux and windows. Luis ir right compatability with AS/400 family is diffrent.

Hello again,

the PAM states that i have to use SLES for Power64 ?

does a Linux X64 (SLES or RHEL) not work ?

Thanks

Hi Björn,

it's right. You can only have Linux on Power Application Servers against IBM i, no Linux on Intel.

Hi Björn,

Christoph is right, but even the Linux on Power application servers are only supported up to SAP NetWeaver 7.02 (EHP2 of SAP NW 7.0) and 7.11 (EHP1 of SAP NW 7.1). We dropped support with newer versions a while ago.

Hi Bjoem,

It is possible. I did similar setup. You have to use distributed installation option of SAPINST. In brief you need to plan as follows

1) Build your CI ( Linux system)

2) Build your Database - IBM i

    -- create a separate /sapmnt/SID/exe file system for IBM i SAP executable

    -- Mount /sapmnt/SID/global and /sapmnt/SID/profile from Linux CI

    -- Make sure that unix level UID abd GUID are same accross both the servers

3) Install database software (only) on DB host ( IBM i)

4) Install Globalhost in case of ABAP, SCS in case of Java stack ( using SAPINST) on Linux system

5) Create + install database instance using SAPINST ( on IBM i) DB host

6) Go back to your Linux host and install CI using SAPINST

Step 4 to 6 : you will get these options in SAPINST.

I think this will help you.

Hi Dipam,

We want to install CI on windows and DB on linux,and we have preparedthe global host also.

but while mounting profile from CI to Linux we are getting the following issue.

"the default profile owned by GID 0,which is the GID of group root.

SOLUTION: Remove  the group account root

can you please let me know,how you mounted the profile from windows to linux.

with regards,

Hi Samarth,

You can use third party software to mapped Windows file to linux OR you can download appropriate RPM to mount Windows file system to Linux.

Say for example if you are using NTFS, please download appropriate RPM form

• http://linux-ntfs.sourceforge.net/info/redhat.html

Mount the file system from Linux.

Good luck.
