Profiles determine certain system resources available to member users, and can also set password control parameters.

  1. From an administrative client, log on as user DBC.
  2. Create the profile for the database administrator, user DBADM. To do this, specify values for the following fields and controls:

Do not enter values at this time for fields not listed.

Field Description
Profile Name Required. The name of the database administrator profile.

Administrative procedures in this publication use the name DBADM for the administrator profile.

User DBADM will be the only member of this profile. Because of space and ownership concerns, you must create a separate profile for other administrative users.
Account Optional. An account string defines the following characteristics for profile member sessions in the database:
  • Session priority. This classification is in effect only when TASM or TIWM classification processes do not match the request to a user-defined workload.
  • Account ID (to assign charges for system time and resources)
  • Date stamp
  • Time stamp

Recommendation: Define at least one account string per profile. If necessary, you can add an account string later using a MODIFY PROFILE statement.

For more about accounts, see Setting Up Your Administrative Environment: All DBAs.

Password Required. The temporary password for DBADMIN.

Recommendation: Create a simple temporary password. Each user is prompted to change the temporary password to a permanent, private password upon first logon to the database.

Spool Space Optional. The spool space specification is only a limit to the amount of space available for intermediate query results or formatted answer sets to queries and volatile tables. The system borrows spool space for a user from unused permanent space anywhere in the system.

Recommendation:Set this value equal to the amount of space in the Spool_Reserve database.

Temporary Space Not applicable. Required only when using global temporary tables and other advanced features.

Recommendation: Temporary space specification is not normally needed. Specification of temporary space requires that you develop a strategy for use of the advanced features that need temporary space. If necessary, you can add a temporary space specification later with a MODIFY USER statement.

Comment Optional. Use this space to describe the profile or note contingencies.
Expire Required. The number in days until a password expires. Set this value to a positive, non-zero number to cause passwords to expire.

Recommendation: 90 days is a common password expiration interval.

Other password controls Optional.

Recommendations: Set other password controls globally by updating DBC.SysSecDefaults if required by your site security policy. Be sure to review the default password control values to determine whether they conform to your site security requirements.

For information on the default password control values and how to change them, see Chapter 6: “Managing Database Passwords,” in Security Administration.

For example:

ACCOUNT=('$H-DBC-MANAGER','  account__str2','  account_str3')
