NW Application Server Installation (NW702)

[Former Member]

Hello everyone,

A bit of a background on my situation.

I have been tasked with replacing our production SAP BW Netweaver application servers (currently three)

The current production landscape:

    CI: SAP BI 7.3.7 - NW 7.3 --> Kernel: 720_REL 64bit UC PL 201

          OS: AIX 6.1.0.0 DB: Oracle: 11.2

    AS: SAP BI 7.3.7 - NW 7.3 --> Kernel: 720_REL 64bit UC PL 201

          OS: AIX 6.1.0.0

The current development landscape:

    CI: SAP BI 7.3.7 - NW 7.3 --> Kernel: 720_REL 64bit UC PL 201

          OS: AIX 6.1.0.0 DB: Oracle: 11.2

Now I have been asked to replace the AIX application servers with IBM Linux on Power (SLES11SP3). This include Dev/QA/Prod.

So rather than jumping in and join a system to a production setup, I am trying to add an application server to the Development first.

I was originally looking at using the Master installer (51042263_6) which contained the installer for NW 703 and them upgrade the Application servers kernel once the installation is completed. However I have found that this installer requires the Oracles 11.2 client installer. Well, unfortunately Oracle only created a 10.2 client installer for Linux on Power. So that installer was a no go.

So I have been using the older installer (51044357_BS7i2010_IDES). This is having me install NW 702 and I was going to take the same path as before with upgrading the kernel. I was able to supply the Oracle 10.2 package without any problem at this point and I am able to get through the installation parameter inputs successfully. The installation appears to be going well, however it appears when it is trying to connect to the database I get the following error:

Last error reported by the step :Java EE Engine configuration error. DIAGNOSIS: See output of log file batchconfig.log: ' Can not get DB connection. Batchconfig will only be able to execute offline tasks.

Now when I look in this file I only see the "Can not get DB connection. Batchconfig will only be able to execute offline tasks." So this has not clued me to anything. I have check and reran again without any changes.

• I can resolve the hostname for the dev AS to CI and from CI to AS.
• Folder and file permissions are correct.
• SAPLOCALHOST in DEFAULT.PFL is commented out.
• checked the /etc/services and remove all entries that overlap with SAP services.
• Firewall on AS is temporarily turned off.
• r3trans -d returns 0 code so it appears to be able to connect to DB

Now I was able to get the installation to complete to but function properly by using a combination of two techniques:

• ./sapinst SAPINST_SKIP_ERRORSTEP=true
• Modify keydb.xml and change CDATA[ERROR] to CDATA[OK].

I can include sapinst_dev.log (last ~20k lines) if needed.

I am not sure at this point what to try. If anyone has any helpful advice, it would be greatly appreciated.

Thanks,

     We are looking to eventually replace the application servers in production, but we currently do not have application servers in development. I am trying to create an application server in development first, then create new application servers in production to phase out the old application servers.

I am installing on a fresh install of SLES11 sp3 for the new application servers.

@Deepak Kori

     The current CI is and will be running on AIX. Only the application servers in all landscapes will be migrated. So the environment is currently homogeneous and will be heterogeneous.

Hi Kenneth,

Now I have been asked to replace the AIX application servers with IBM Linux on Power (SLES11SP3). This include Dev/QA/Prod.

Can you elaborate a bit further as such whether your DB instance is also running on AIX and you want to migrate everything from AIX to Suse Linux ?

Hi Ken,

My understanding is - You want to replace your application servers.

I was originally looking at using the Master installer (51042263_6) which contained the installer for NW 703

???

You can directly install AAS on new HW and it can be added to your current landscape. Heterogeneous installations are supported.
