A user profile may be a set of limits on the database resources and therefore the user password. Once you assign a profile to a user, then that user cannot exceed the database resource and password limits.

The CREATE PROFILE statement allows you to make a replacement user profile. the subsequent illustrates the essential syntax of the CREATE PROFILE statement:

CREATE PROFILE profile_name
LIMIT { resource_parameters | password_parameters};

In this syntax:

First, specify the name of the profile that you simply want to make .
Second, specify the LIMIT on either database resources or password.

resource_parameters

You use the subsequent clauses to line the limit for resource parameters:

SESSIONS_PER_USER – specify the amount of concurrent sessions that a user can have when connecting to the Oracle database.
CPU_PER_SESSION – specify the CPU deadline for a user session, represented in hundredth of seconds.
CPU_PER_CALL – specify the CPU deadline for a call like a parse, execute, or fetch, expressed in hundredths of seconds.
CONNECT_TIME – specify the entire time period limit for a user session, expressed in minutes.
IDLE_TIME – specify the amount of minutes allowed periods of continuous inactive time during a user session. Note that the long-running queries and other operations won’t subject to the present limit.
LOGICAL_READS_PER_SESSION – specify the allowed number of knowledge blocks read during a user session, including blocks read from both memory and disk.
LOGICAL_READS_PER_CALL – specify the allowed number of knowledge blocks read for a call to process a SQL statement.
PRIVATE_SGA – specify the quantity of personal memory space that a session can allocate within the shared pool of the system global area (SGA).
COMPOSITE_LIMIT – specify the entire resource cost for a session, expressed in commission units. the entire service units are calculated as a weighted sum of CPU_PER_SESSION, CONNECT_TIME, LOGICAL_READS_PER_SESSION, and PRIVATE_SGA.

password_parameters

You use the subsequent clauses to line the bounds for password parameters:

FAILED_LOGIN_ATTEMPTS – Specify the amount of consecutive failed login attempts before the user is locked. The default is 10 times.
PASSWORD_LIFE_TIME – specify the amount of days that a user can use an equivalent password for authentication. The default value is 180 days.
PASSWORD_REUSE_TIME – specify the amount of days before a user can reuse a password.
PASSWORD_REUSE_MAX – specify the amount of password changes required before the present password are often reused. Note that you simply must set values for both PASSWORD_REUSE_TIME and PASSWORD_REUSE_MAX parameters make these parameters become .
PASSWORD_LOCK_TIME – specify the amount of days that Oracle will lock an account after a specified number of a consecutive failed login. The default is 1 day if you omit this clause.
PASSWORD_GRACE_TIME – specify the amount of days after the grace period starts during which a warning is issued and login is allowed. The default is 7 days once you omit this clause.

Note that to make a replacement profile, your user must have the CREATE PROFILE system privilege.

Oracle CREATE PROFILE examples

To find the present profile of a user, you query it from the dba_users deem shown within the following statement:

SELECT
 username,
 profile
FROM
 dba_users
WHERE
 username = 'OT';
Here is that the output:

So the user OT has the DEFAULT profile.

When you create a user without explicitly specifying a profile, Oracle will assign the DEFAULT profile to the user.

To find the parameters of DEFAULT profile, you query the dba_profiles as shown within the following query:

SELECT
 *
FROM
 dba_profiles
WHERE
 PROFILE = 'DEFAULT'
ORDER BY
 resource_type,
 resource_name;

Here is that the output:

1) Using Oracle CREATE PROFILE to line the resource limit example

First, create a profile called CRM_USERS that set the resource limits:

CREATE PROFILE CRM_USERS LIMIT
 SESSIONS_PER_USER UNLIMITED
 CPU_PER_SESSION UNLIMITED
 CPU_PER_CALL 3000
 CONNECT_TIME 15;

Second, create a user called CRM:

CREATE USER crm IDENTIFIED BY abcd1234
PROFILE crm_users;

Third, verify the profile of the CRM user:

SELECT
 username,
 profile
FROM
 dba_users
WHERE
 username = 'CRM';

The user CRM is subject to the subsequent limits: the CRM user can have any number of concurrent sessions (SESSIONS_PER_USER). In each session, it can consume any amount of CPU time (CPU_PER_SESSION). additionally , the CRM user cannot consume quite 30 seconds of CPU time during a single call. (CPU_PER_CALL) and every session cannot last for quite quarter-hour .

2) Using Oracle CREATE PROFILE to line the password limit example

First, create a replacement profile called erp_users with password limits:

CREATE PROFILE erp_users LIMIT
 FAILED_LOGIN_ATTEMPTS 5
 PASSWORD_LIFE_TIME 90;

Then, create a user named sap and set its profile to erp_users:

CREATE USER sap IDENTIFIED BY abcd1234
PROFILE erp_users;

The sap user is subject to the subsequent password limits:

The number of consecutive failed login attempts (FAILED_LOGIN_ATTEMPTS) is 5 before the account is locked.
The number of days to vary the password is 90 days.
