Perform this task to set up the operating system security prerequisites
for a WebSphere Application Server for z/OS cell. This ensures that all servers
in the cell are using the same operating system security definitions.
Before you begin
Install the WebSphere Application Server for
z/OS product code and review the instructions for using the Customization
Dialog. Have available a copy of the worksheet that you completed as part
of Planning for common groups and users.
About this task
You need to perform this task before configuring any application
serving environment that uses the common groups and users. If a new WebSphere
Application Server for z/OS cell or server on a z/OS system will use the exact
same common group and user definitions as an existing server or cell on the
same z/OS system, you do not need to repeat this task.
You
need to run the jobs generated as part of this task once per security database.
If z/OS systems do not share a RACF or other security database, you are responsible
for making sure identical security definitions are in place for all WebSphere
Application Server for z/OS user IDs, groups, and profiles. See Preparing the security server (RACF) for more information.
Procedure
- Log on to TSO on the z/OS system on which you intend to configure
the common groups and users. Use a user ID that has READ access
to the WebSphere Application Server for z/OS product data sets.
- Start the Customization Dialog. See Starting the Customization Dialog for details.
- Choose the configuration data sets in which you will store your
customization jobs and data. See Choosing configuration data sets for details.
- Set the customization variables according to the values recorded
on your common groups and users worksheet. See Setting the customization variables: Common groups and users for details.
- Save the common groups and users customization variables in a data
set that you will use in later customization steps. See Saving the common group and user variables for details.
- Create the customization jobs and files, based on the customization
variable values you entered. See Creating the customization jobs and files for details.
- Follow the generated customization instructions. See Following the generated customization instructions: Security domain for details, and a sample set of customization instructions.
Results
You have finished when you have successfully completed the steps in
the generated instructions. The common groups and users is in place on the
chosen z/OS system. If any z/OS systems that interoperate with or host your
planned application serving environment do not share the security database
you updated as part of this task, update the security databases of the other
systems accordingly.
What to do next
Proceed with the configuration of the application serving environments
that use this common group and user.
