1. Naming schema changes for some XI/PI components in SLD
For High Availability (HA) setup, the SLD naming schema for Integration Server, Domain and Adapter Engine are a little bit different.
- The SLD name of Integration Server and Domain are built as is.<cisysnr>.<cihost> and domain.<cisysnr>.<cihost>. The Central Instance hostname is taken from the ABAP profile parameters.
- The SLD name of Adapter Engine contains the name of J2EE Database. It's built as af.<system_id>.<j2ee_dbhost>. Because several Adapter Engines can be part of the same domain, e.g. central Adapter Engine + non-central Adapter Engines, the Adapter Engine name cannot contain the host name of central instance, but needs to have a unique name for each Adapter Engine. The value for j2ee_dbhost is taken from the Java profile parameters.
- You can check the profile parameters in the folder /usr/sap/<SID>/SYS/profile.
2. parameter "com.sap.aii.connect.integrationserver.sld.name"
The value of parameter "com.sap.aii.connect.integrationserver.sld.name" mentioned in HA notes is as below:
<is sld name> Default: is.<cisysnr>.<cihost>
- You can configure it under http://<host>:<hport>/dir/start/index.jsp -> Administration -> Exchange Profile -> Parameters -> Connections. You might have some doubts whether this parameter will work if you switch from CI to DI.
- In fact the value of this parameter is just an identifier that does not have any particular meaning for the java stack. It is just used to avoid many SLD reads. So there you should put the host name and instance number of CI. This term is somehow outdated because when stripping the ASCS from CI, it becomes a plain DI. But anyway, one of the DI's is denoted central and this is defined during the system install. So the CI "knows" it is the central one and this exact instance is used to define the name of the integration server.
- So if installed according the HA notes, there should be no problems if the CI is offline, the DI known which CI it belongs to and uses it to recreate SLD content if necessary.
