   Tutorials for Developing a BEA Tuxedo Application

1. Before booting bankapp, verify that your machine has enough IPC resources to support your application. To generate a report on IPC resources, run the tmboot command with the -c option.

   Note: Because insufficient IPC resources may lead to a boot failure, it is imperative that you ensure you have appropriate values specified for your configuration.

2. Add the number of application clients used per processor to each MSGMNI value. MSGMAP should be twice MSGMNI.

3. Compare the minimum IPC requirements to the parameters set for your machine. The location of these parameter settings is platform-dependent:

   • On many UNIX system platforms, machine parameters are defined in /etc/conf/cf.d/mtune.

   • On Windows NT platforms, machine parameters are set and displayed through a control panel.

• Running bankapp
