Tuxedo configuration and runtime

We know how to configure various Tuxedo components quite well by now, so in this section we will discuss only the configuration relating to an Exalogic machine.

The UBBCONFIG file

In this section, we will discuss all the configuration related tasks using the UBBCONFIG file. We will be introduced to some more parameters in the UBBCONFIG file and some environment variables that need to be set for running Tuxedo on an Exalogic box. In MP mode, communication between two nodes is done through a bridge, but in Exalogic's cross-node, communication can be leveraged using remote direct memory access (RDMA). You need to specify RDMA with option values in the MACHINES section; there are four options, which are as follows:

• RDMADAEMONIP: This is the IP (IPoIB ) address, but it is not an Ethernet-based IP address, and the Msgq_daemon process is bound with it. You need to configure a one-to-one configuration for Msgq_daemon and the logical machine.

• DMADAEMONPORT: This is a...
