Part 3 Part 3 Availability tests In this part we describe the applications we used for our tests and how we tested the infrastructure to make sure it withstood failures in the various components. We did not test all the situations that we tested in the first version of this redbook. For this update, we did not need to test the hardware failures (CPU, LPAR, and CF), or some of the software failures (LDAP, DB2, and RRS) that had nothing to do with WebSphere, since those components had not changed since the previous edition. © Copyright IBM Corp. 2002, 2004, 2006.
