Installing DB2

Installing DB2® involves running the installation jobs, connecting the facilities that allow TSO, batch, IMS™, and CICS® to access DB2 resources, and preparing DB2 for use. After you complete the installation steps, your DB2 subsystem will be in new-function mode. In new-function mode, all DB2 10 function is available for use.

Before you begin

Before you begin installing DB2:

  • Start of changeReview the information about DB2 security with your system security administrator, and plan and implement your DB2 security environment. See in particular Defining RACF user IDs for DB2-started tasks and Permitting RACF access, which can help you plan your security environment even if you use an alternative security product. After initial installation of DB2, subsequent installation tasks and jobs require specific authorization in order to connect to DB2.End of change
  • Complete the SMP/E steps, load the DB2 libraries, and run the installation CLIST to tailor the DB2 jobs to your environment..
  • Start of changeDefine an SMS environment for DB2. At a minimum, the data sets for the DB2 catalog and directory must be SMS-managed. For information on using sample job DSNTIJSS to define an SMS environment for data sets that are associated with the DB2 catalog and directory, see Installation step 1: Define the SMS environment for DB2 catalog and directory data sets: DSNTIJSS.End of change
  • If you plan to have data sharing enabled (Enable option on panel DSNTIPP1), you should save all your jobs from the original installation or migration in a different data set than the enabling jobs. If you save them in prefix.NEW.SDSNSAMP, the jobs might be overwritten.
  • See the DB2 Program Directory for keyword specifications used for Preventive Service Planning (PSP). Use Information/Access or the ServiceLink facility of IBMLink to check the most current information about DB2 and other products. Contact the IBM® Support Center if you do not have access to IBMLink.

You must not use secondary authorization IDs to perform any of the following installation steps.

Procedure

After you complete the SMP/E steps and run the installation CLIST, you can edit and run the jobs that install your DB2 DB2 10 subsystem. A new installation starts in new-function mode.
