10.2 Installing the DB2 Grouper component The DB2 Grouper component is a client-server program. Thus, you need to install files on both a server and a client. 10.2.1 Installing the DB2 Grouper server The DB2 Grouper server is actually a set of stored procedures that are installed into each database that you want to investigate. There is no process or service that runs in the background, as you might expect when something is called a server . When you initiate a Group Discovery from the DB2 Grouper client, the stored procedure executes and populates the DB2 Grouper tables in the database. Important: The DB2 Grouper documentation, which includes the user's guide and the help files, uses the term DB2 Grouper server . This term really means the individual database into which you have installed the DB2 Grouper stored procedures. It does not refer to the instance or machine onto which you installed DB2 Grouper. You must install the DB2 Grouper stored procedures into each database with which you want to work. Thus, you need to think of each database as the DB2 Grouper server in the context of the DB2 Grouper documentation. Installing the DB2 Grouper server in a UNIX environment Attention: In this section, we describe the steps that we performed when installing DB2 Grouper server on a Linux environment in the ITSO lab that we used for this book. This is not a replacement for the official installation instructions, which you can find in IBM DB2 Grouper User's Guide, SC18-7409. To install the DB2 Grouper server in a UNIX environment, follow these steps: 1. Login as root. 2. You must run the db2profile of the instance you want to use. We suggest that you also verify that the DB2 environment is set properly by issuing a simple command such as db2level. Example 10-1 on page 308 shows an example of this command from Linux. 3. Verify that you have an appropriate Java in the PATH for root (see also Example 10-1 on page 308). 4. Change to the directory where the setup program exists. Chapter 10.
