Installing and Configuring DB2 Clients

Creating or Assigning Groups and Users

If you do not already have a user ID to own the instance and a system administration group ID that is the primary group of the instance owner, create these as follows:

1. Log in as root.

2. Create a system administration group ID. Use these commands on the following operating systems:

   SINIX, SGI

   Use sysadm or groupadd

   SCO OpenServer

   Use scoadmin or groupadd

   For example, to create a group named dbadmin1 on SCO OpenServer, type:

      groupadd dbadmin1
   

   Use the appropriate command for the other operating systems when you create a group.

3. Create a user ID that will be the instance owner.

   SINIX, SGI

   Use sysadm or useradd

   SCO OpenServer

   Use scoadmin or useradd

   For example, to create a user named inst1 on SCO OpenServer, type:

      useradd -g dbadmin1 -G dbadmin1 -d /home/inst1 inst1
      passwd inst1
   

   Use the appropriate command for the other operating systems when you create a user.

When choosing a name for a group or user, follow the rules described in Appendix C. "Naming Rules". Dedicate the instance-owner user ID to that instance's use only. This allows for easier error recovery if a system error occurs.
