Log Reader Agent Security

The Log Reader Agent Security dialog box allows you to specify:

The Microsoft Windows account under which the Log Reader Agent runs at the Distributor. The Windows account is also referred to as the process account, because the agent process runs under this account.
The context under which the Log Reader Agent makes connections to the Microsoft SQL Server Publisher. The connection can be made by impersonating the Windows account or under the context of a SQL Server account you specify.

Note

The Log Reader Agent makes connections to the Publisher even if the Publisher and Distributor are on the same computer. The Log Reader Agent also makes connections to the Distributor; these connections are always made by impersonating the Windows account under which the agent runs.

For Oracle Publishers, specify the context under which the Log Reader Agent connects to the Publisher in the Publisher Properties dialog box (available from the Distributor Properties dialog box). For more information, see View and Modify Replication Security Settings.

All accounts must be valid, with the correct password specified for each account. Accounts and passwords are not validated until an agent runs.

Options

Process account
Enter a Windows account under which the Log Reader Agent runs at the Distributor. The Windows account you specify must at minimum be a member of the db_owner fixed database role in the distribution database.
Password and Confirm password
Enter the password for the Windows account.
Connect to the Publisher
Select whether the Log Reader Agent should make connections to the Publisher by impersonating the account specified in the Process account text box or by using a SQL Server account. If you select to use a SQL Server account, enter a SQL Server login and password.

Note

Microsoft recommends that you select to impersonate the Windows account rather than using a SQL Server account.

The Windows account or SQL Server account used for the connection must at minimum be a member of the db_owner fixed database role in the publication database.
