Modifying the Oracle Connect String

The Oracle Connect String is a user account with database administrator privileges you use to access the standard and recovery catalog databases.

Note: If you want to use a user account other than ‘sys’, you must grant the SYSDBA or SYSBACKUP (in Oracle version 12 or higher) privilege to the user account.

The account information is provided as a connect string with the following information:

  • The Oracle Database user ID
  • The Password for the user ID
  • The Oracle Service name

You can use separate accounts to access the standard database and the recovery catalog database. The recovery catalog database user account must have recovery catalog owner privileges.

By default, the user account for the standard database has administration privileges. If you want to use a different account, use the following table for the user account requirements to access the database:

Account Type The User Account Must Have:
  • Oracle database administration privileges
  • SYSDBA or SYSBACKUP (in Oracle version 12 or higher), ALTER SYSTEM, and SELECT ANY TABLE system privileges.
Non-Administrator Access to specific objects (as opposed to the admin account with the SELECT ANY TABLE privilege)

For example:


The Oracle database administrator can establish all other accounts except an Impersonate User.

About This Task

By default, when you discover or create an Oracle instance, the SnapProtect software automatically creates an archive log subclient. You can disable this feature by setting an additional setting. For more information, see Disabling Automatic Archive Log Subclient Creation.

You can configure the data and log storage policies when you manually or automatically discover instances (Agent Properties dialog box, Data Storage Policy list, Log Storage  Policy list, General tab). The SnapProtect software assigns these storage policies to all instances and default subclients that you discover.

By default, the command line storage policy is set to the agent data storage policy.

The log storage policy is assigned to the Oracle instance.

The SnapProtect software assigns the data storage policy to the default subclients by looking at the following configured items:

  1. The storage policy configured for the Oracle Agent (Data Storage Policy list, Log Storage Policy list, General tab)
  2. The storage policies that are configured for a previously discovered Oracle instance (Instance Properties dialog box, Storage Device tab, Log Backup tab, Storage Policy used for all archive log backup list)
  3. The storage policy for the File System Agent default agent for the default backup set (Subclient Properties dialog box, Storage Device tab, Data Storage Policy tab, Storage Policy list)


  1. From the CommCell Browser, expand Client Computers > client > Oracle.
  2. Right-click the instance and then click Properties.

    The Instance Properties dialog box is displayed.

  3. On the Details tab, determine how to connect to the Oracle database.
    • To use the Oracle Wallet feature (Secure External Password Store), select the Oracle Wallet Auto Login check box and just provide the TNS service name in the third Connect String box.

      Note: If you provide the user name and password, the software ignores the Oracle Wallet feature.

    • To use the Oracle Connect String, select the Use Connect String check box and in the Connect String box provide the user name, the user password and the TNS service name.

      Note: If you want to use an account that is other than 'sys', you must grant the SYSDBA or SYSBACKUP (in Oracle version 12 or higher) privilege to the user account.

  4. Click OK to close the Instance Properties dialog box.
