Managing Serviceguard Extension for SAP Version B.05.10, September 2010

If you cluster a Central Instance or an ABAP System Central Service Instance, configure the
frontend PCs to attach to <relocci>.
Most of the time, this can be achieved by distributing a new saplogon.ini file to the windows
directory.
SAP J2EE Engine specific installation steps
This section is applicable for SAP J2EE Engine 6.40 based installations that were performed prior
to the introduction of SAPINST installations on virtual IPs. There is a special SAP OSS Note
757692 that explains how to treat a hostname change and thus the virtualization of a SAP J2EE
Engine 6.40. Depending on the SAP application component that is clustered, there might be
additional steps documented as part of a SAP white paper that covers clustering of the component.
Installation Step: NW04J1210
If the SAP component installed also depends and utilizes a SAP J2EE Engine, some configuration
tasks have to be performed in order for the J2EE instance to interact in the virtualized
environment.
The following lines will give some hints about the settings necessary for the switchover of the
J2EE Engine 6.40, but always refer to SAP OSS Note 757692 because this note is always kept
up-to-date.
For virtualizing the J2EE DB Connection:
• Log on to the J2EE Configuration Tool
• Choose secure store
• Change the following values:
admin/host/<SID> <relocdb>
For Oracle databases replace the hostname in the connection string:
jdbc/pool/<SID>/Url jdbc:oracle:thin@<relocdb>:1527:<SID>
Installation Step: NW04J1220
These settings have to be adjusted for the switchover of the J2EE part of the SAP WEB AS;
the following configuration has to be performed in the Offline Configuration Editor:
• Log on to the Offline Configuration Editor.
