How to Create Multiple User In Oracle 10G?

To create multiple users in Oracle 10g, you can use the CREATE USER statement in SQL. This statement allows you to specify the username, password, and other attributes for each user you want to create. You can also assign users to specific roles or grant them privileges on specific objects.

For example, to create a new user named "user1" with the password "password1", you can use the following SQL statement:

CREATE USER user1 IDENTIFIED BY password1;

You can then grant this user specific privileges or roles as needed using the GRANT statement. Repeat this process for each user you want to create in Oracle 10g.

How to synchronize user data for multiple users in Oracle 10g?

To synchronize user data for multiple users in Oracle 10g, you can use the following methods:

1. Replication: Oracle provides replication features that allow you to replicate data from one database to another in real-time or on a scheduled basis. You can set up replication to synchronize specific tables or schemas across multiple databases.
2. Oracle Streams: Oracle Streams is a feature that enables you to capture and propagate data changes, events, and messages in real-time. You can use Oracle Streams to synchronize user data between multiple databases within the same data center or across different locations.
3. Data Pump: Oracle Data Pump is a tool that allows you to export and import data between databases. You can use Data Pump to export user data from one database and import it into another database to synchronize the data.
4. Oracle GoldenGate: Oracle GoldenGate is a real-time data integration and replication tool that allows you to capture, route, and deliver transactional data across multiple databases. You can use GoldenGate to synchronize user data between multiple databases with minimal latency.
5. Database Links: Oracle allows you to create database links that establish a connection between two databases. You can use database links to select, insert, update, or delete data across different databases, helping you synchronize user data between multiple databases.

By using these methods, you can effectively synchronize user data for multiple users in Oracle 10g and ensure that all databases have the same up-to-date information.

How to audit user activity for multiple users in Oracle 10g?

To audit user activity for multiple users in Oracle 10g, you can use the built-in auditing feature that comes with Oracle database. Here are the steps to audit user activity for multiple users:

1. Enable auditing: First, you need to enable auditing at the database level by setting the AUDIT_TRAIL parameter to "DB" in the initialization parameter file (init.ora) or using the ALTER SYSTEM command:

1

ALTER SYSTEM SET AUDIT_TRAIL=DB SCOPE=SPFILE;

1. Create audit policies: Next, you need to create audit policies to specify the type of activities you want to audit for each user. You can create audit policies using the following SQL statement:

1

AUDIT ...

For example, to audit all SELECT, INSERT, UPDATE and DELETE operations for the users HR and SALES, you can create audit policies like this:

1
2

AUDIT SELECT, INSERT, UPDATE, DELETE ON HR.SCHEMA BY ACCESS;
AUDIT SELECT, INSERT, UPDATE, DELETE ON SALES.SCHEMA BY ACCESS;

1. Start the audit trail: Once the audit policies are in place, you need to start the audit trail using the following SQL statement:

1

AUDIT ALL;

This will start auditing activities based on the policies you have defined.

1. Query the audit trail: To view the audit data for multiple users, you can query the DBA_AUDIT_TRAIL view in Oracle. You can filter the results based on the username or specific activities to analyze the user activity.

1

SELECT * FROM DBA_AUDIT_TRAIL WHERE USERNAME IN ('HR', 'SALES');

By following these steps, you can effectively audit user activity for multiple users in Oracle 10g. Make sure to regularly review the audit data to identify any suspicious activities and ensure the security of your database.

What is the syntax for creating multiple users in Oracle 10g?

To create multiple users in Oracle 10g, you can use the following SQL script:

1
2
3

CREATE USER user1 IDENTIFIED BY password1;
CREATE USER user2 IDENTIFIED BY password2;
CREATE USER user3 IDENTIFIED BY password3;

You can replace user1, user2, and user3 with the desired usernames, and password1, password2, and password3 with the desired passwords for each user.
