Step 2. Specify Details

Specifying the parameters will define how your LANSA Stack behaves. It is the most important step in creating a stack and needs to be considered carefully. But, the worst that may happen is you need to recreate the stack again. You will see that instantiating a stack is not difficult to do, but understanding the effects of the various parameters and what will suit your application is another matter. Still, it's a great environment to try it and see what happens. All the help text for this dialog is provided on the dialog.

1.  Specify the name of the stack e.g. LansaStack

2.  The most important parameters that you must specify are listed under the Essential Parameters group (in template order):

a.  Lansa MSI URL, unless you are running the demo

b.  Database Password

c.  Web Server Password

d.  Keypair Name

e.  Remote Access Location CIDR

f.  It's also advisable to change the Database Username and Web Server User to non-default values

3.   The remainder of the parameters may be skipped if creating a demonstration stack.

4.   The Database Configuration and Web Server Configuration parameters are highly dependent on the application requirements. Some starting points for determining the values of these parameters is provided in the Benchmark Configuration.

5.  The parameters grouped under Stack Maintenance are only relevant when updating the stack. All the Trigger parameters are examples of this and they have no effect when creating the stack, so you may safely skip them for the moment. Exercises using the Triggers are provided later on.

6.  Review each of the parameters and their help text in the Specify Parameters dialog.

7.  Click Next.
