Database User for Oracle GoldenGate Processes for DB2 LUW

Create a database user that is dedicated to Oracle GoldenGate. It can be the same user for all of the Oracle GoldenGate processes that must connect to a database:
- Extract (source database)
- Replicat (target database)
- DEFGEN (source or target database)
To preserve the security of your data, and to monitor Oracle GoldenGate processing accurately, do not permit other users, applications, or processes to log on as, or operate as, the Oracle GoldenGate database user. It is recommended that you store the login credentials in an Oracle GoldenGate credential store. The credential store makes use of local secure storage for the login names and passwords, and permits you to specify only an alias in the Oracle GoldenGate parameter files.
Assign system administrator (SYSADM) or database administrator (DBADM) authority to the database user under which Extract runs. To give the Extract user DBADM authority, a user with SYSADM authority can issue the following grant statement.
```
GRANT DBADM ON DATABASE TO USER user
```
This authority can also be granted from the User and Group Objects folder in the DB2 Control Center. The database tab for the user that is assigned to an Oracle GoldenGate process should have the Database Administrative Authority box checked.
Note:

If the Extract user does not have the required authority, Extract will log the following errors and stop.
```
[SC=-1224:SQL1224N A database agent could not be started to 
service a request, or was terminated as a result of a database 
system shutdown or a force command. 
SQL STATE 55032: The CONNECT statement is invalid, because the 
database manager was stopped after this application was started]
```
Grant at least the following privileges to the database user under which Replicat runs:
- Local CONNECT to the target database
- SELECT on the system catalog views
- SELECT, INSERT, UPDATE, and DELETE on the target tables
