Besides user profiles, you can also use some third-party tools that include query governs, which limit the types of queries that users can use within the database, thus ensuring that the database is not loaded down by inefficient queries.

Oracle databases enable you to set limits on several parameters within a profile. The following sections provide brief explanations of these parameters, which can be divided into two broad types: resource parameters, which are concerned purely with limiting resource usage, and password parameters, used for enforcing password-related security policies.

The main reason for using resource parameters is to ensure that a single user or a set of users doesn t monopolize the database and server resources. Here are the most important resource parameters that you can set within an Oracle Database 10g database: CONNECT_TIME: Specifies the total time (in seconds) a session may remain connected to the database. CPU_PER_CALL: Limits the CPU time used per each call within a transaction (for the parse, execute, and fetch operations). CPU_PER_SESSION: Limits the total CPU time used during a session. SESSIONS_PER_USER: Specifies the maximum number of concurrent sessions that can be opened by the user. IDLE_TIME: Limits the amount of time a session is idle (which is when nothing is running on its behalf). LOGICAL_READS_PER_SESSION: Limits the total number of data blocks read (from the SGA memory area plus disk reads). LOGICAL_READS_PER_CALL: Limits the total logical reads per each session call (parse, execute, and fetch). PRIVATE_SGA: Specifies a session s limits on the space it allocated in the shared pool component of the SGA (applicable only to shared-server architecture systems). COMPOSITE_LIMIT: Sets an overall limit on resource use. A composite limit is a limit on the sum of several of the previously described resource parameters, measured in service units. These resources are weighted by their importance. Oracle takes into account four parameters to compute a weighted COMPOSITE_LIMIT: CPU_PER_SESSION, CONNECT_TIME, LOGICAL_READS_ PER_SESSION, and PRIVATE_SGA. You can set a weight for each of these four parameters by using the ALTER RESOURCE COST statement, as shown in the following example: SQL> ALTER RESOURCE COST 2 cpu_per_session 200 3 connect_time 2; Resource cost altered.

Oracle provides you with a wide variety of parameters to manage user passwords. You can set the following password-related profile parameters to enforce your security policies: FAILED_LOGIN_ATTEMPTS: Specifies the number of times a user can attempt to log in before being locked out. PASSWORD_LIFE_TIME: Sets the time limit for using a particular password. If you don t change the password within this specified time, the password expires.
CHAPTER 11 USER MANAGEMENT AND DATABASE SECURITY
PASSWORD_GRACE_TIME: Sets the time period during which you ll be warned that your password has expired. After the grace period is exhausted, you can t connect to the database with that password. PASSWORD_LOCK_TIME: Specifies the number of days a user will be locked out after reaching the maximum number of unsuccessful login attempts. PASSWORD_REUSE_TIME: Specifies the number of days that must pass before you can reuse the same password. PASSWORD_REUSE_MAX: Determines how many times you need to change your password before you can reuse a particular password. PASSWORD_VERIFY_FUNCTION: Lets you specify your own password-verification function if you don t want to use the default Oracle-provided verification function.
The Default Profile
As you can see, you can set a number of resource- and password-related attributes to control access to the database and resource usage. If you create a user and don t explicitly assign any profile to the user, the user will inherit the default profile, as shown here: SQL> SELECT profile FROM dba_users WHERE username = 'SALAPATI' PROFILE ----------DEFAULT The default profile, unfortunately, isn t very limiting at all virtually all the resource limits are set to UNLIMITED, meaning there s no limit on resource usage whatsoever. Listing 11-1 shows the results of querying the DBA_PROFILES table regarding the attributes for the profile named default. Listing 11-1. Resource Limits for the Default Profile SQL> SELECT DISTINCT resource_name, limit 2 FROM dba_profiles 3* WHERE profile='DEFAULT'; RESOURCE_NAME LIMIT -------------------------------- ---------------IDLE_TIME UNLIMITED CONNECT_TIME UNLIMITED PASSWORD_LIFE_TIME UNLIMITED PASSWORD_LOCK_TIME UNLIMITED LOGICAL_READS_PER_SESSION UNLIMITED PRIVATE_SGA UNLIMITED LOGICAL_READS_PER_CALL UNLIMITED SESSIONS_PER_USER UNLIMITED CPU_PER_SESSION UNLIMITED FAILED_LOGIN_ATTEMPTS 10 PASSWORD_VERIFY_FUNCTION NULL PASSWORD_GRACE_TIME UNLIMITED PASSWORD_REUSE_TIME UNLIMITED PASSWORD_REUSE_MAX UNLIMITED COMPOSITE_LIMIT UNLIMITED CPU_PER_CALL UNLIMITED 16 rows selected.
