This section provides the steps for installing the high-availability database (HADB).
If you plan to run the high-availability database on the Application Server machine, and if you installed HADB when you installed Application Server, skip to Starting HADB.
You can install the HADB component on the same machine as your Application Server system if you have 2 Gbytes of memory and 1-2 CPUs. If not, use additional hardware. For example:
Two 1 CPU systems with 512 Mbytes to 1 Gbyte memory each
One 1-2 CPU system with 1 Gbytes to 2 Gbytes memory
