NW Application Server Installation (NW702)

32 Views

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,

-Ken
