1.4 Configuring Workspace Preferences

Workspace administrators can configure the following preferences for the current workspace, including login controls, support for Application Builder, SQL Workshop, PL/SQL editing, and Team Development.

Topics:

1.4.1 Enabling Account Login Controls for a Workspace

There are two different ways to configure login controls:

  • An Instance administrator enables account login controls for all Application Express accounts in all workspaces across a development instance.

    If your Instance administrator configures these preferences for an instance, those settings display as the defaults for all workspaces. See "Enabling Login Controls for All Workspaces".

  • If the Instance administrator does not enable login controls across an entire instance, then each Workspace administrator can enable the following controls on a workspace-by-workspace basis:

    • Require end-user account expiration and locking

    • Set up a maximum number of failed login attempts for end-user accounts

    • Set the password lifetime for end-user accounts, that is, the number of days an end-user account password can be used before it expires

Tip:

This feature applies only to accounts created using the Application Express user creation and management facilities. It provides additional authentication security for applications. See "Managing Application Express Users".

To enable login controls for a workspace:

  1. Log in to Oracle Application Express. See "Logging In To Oracle Application Express" in Oracle Application Express Application Builder User's Guide.

    The Workspace home page appears.

  2. Click the Administration icon.

    The Administration page appears.

  3. Click Manage Service.

  4. Click Set Workspace Preferences.

  5. Under Account Login Control:

    1. Account Expiration and Locking - Click Enable.

      If you select Enable, end-user account passwords expire after a configurable time period and accounts are locked after a configurable number of authentication failures. Account passwords can be set to expire after the first use.

      If your Instance administrator set the Require User Account Expiration and Locking preference to Yes, this preference defaults to Enable and you cannot update it.

    2. Maximum Login Failures Allowed - Enter a positive integer for the maximum number of consecutive unsuccessful authentication attempts allowed before an end-user account is locked. If you do not specify a value in this field, the instance-level setting for Maximum Login Failures Allowed is used.

    3. End User Account Lifetime (days) - Enter a positive integer for the maximum number of days an end-user account password may be used before the account expires. If you do not specify a value in this field, the instance-level setting for Account Password Lifetime is used.

  6. Click Apply Changes.
