iSeries Access for Web provides administrators and users the ability to customize the product via user or group policies and preferences.

Policies: Provides application level control of functions via policy settings. The policy

settings can be administrated at the user and group profile level. For a complete list of policies, refer to iSeries Access for Web, SC41-5518.

For example, the “Printer output” policy setting can be set to “Deny” for a particular user or group profile to restrict access to that function.

Preferences: Provides users the ability to customize iSeries Access for Web to meet their

needs. User preferences are a subset of available policy settings.

For example, the “Printer output list columns” preference can be modified by a user to set the columns they want to see when viewing their printer output list.

3.3.1 Restricting functions

iSeries Access for Web supports policies that control what functions a user can perform. An administrator can allow or deny a user or a group of users access to an entire function or to individual actions of a function.

For example, an administrator could restrict all users from the Jobs function. They could allow users in the ACCOUNTING group to run database requests, but deny them access to other database actions. They could also restrict user JOE from running batch commands. When a user is denied access to a function or action, the function is not available from the navigation bar or as a page link. Preferences are also available to prevent function tabs from being displayed on the navigation bar. However, these preferences do not restrict users from accessing the function if, for example, they use a bookmark to the function.

3.3.2 List customization

Users can customize how lists are navigated and displayed using list preferences. For example, “Default rows per page” controls the maximum number of rows displayed on an page. “Default pages per set” controls the number of pages defined in a set, when using the “previous set” and “next set” navigation links. These preferences affect all lists. For most lists, you can also customize which columns are displayed and the order these columns appear. See Figure 3-35 for an example of customizing printer output columns.

Some lists support additional customization preferences unique to the supported function. See iSeries Access for Web, SC41-5518, for details on these preferences.

3.3.3 Library filters

Some lists displayed by iSeries Access for Web contain information about objects in libraries. By default, the content of these lists is built by searching libraries in the user portion of the library list. Sometimes these lists can be too large to manage.

The library filter preferences allow you to customize which libraries are used to build the lists. The database “table filter” preference also supports wildcard characters and table names to allow additional filtering on the tables list. For more information, refer to iSeries Access for Web, SC41-5518.

The following library filter preferences are available:

Print, Output queue library filter

Database, Table filter

Command, Default search library

3.3.4 Preferences

Each individual user profile can change user preferences for iSeries Access for Web. This function is allowed by default. If administrators want to restrict users, they must deny users or groups of users access to the function using policies. Preference modifications are saved and associated with their iSeries user profile. Settings are stored in the following paths:

Default settings:

QIBM\ProdData\Access\Web2\config\webaccess.policies

All preferences and customizations:

QIBM\UserData\Access\Web2\<WebServer>\<Serverinstance>\config\webaccess.policies Users can set the following types of preferences:

Column inclusion and ordering for functions that display output in columns

Number of rows per page to display on output

Show or hide navigation bar tabs

Preferred language and character set

Database table filters and default database connection

Number of commands to save in the run command history

Users can also change iSeries Access for Web preferences by selecting Customize from the navigation bar. Figure 3-37 shows the Customize tab.

Figure 3-37 Customize tab

Select Preferences, and the Preferences page is displayed as shown in Figure 3-38.

Figure 3-38 Preferences

Users can customize iSeries Access for Web from this location. Select a category to see the preferences that are available to customize. Once a preference is changed, users can select one of three actions:

Use current setting: Any setting modifications are added to the profile. If no settings are

changed, no action is performed.

Apply setting to profile: Ensures your profile is updated with the preference selected. All

settings are written to the profile, regardless of whether the values changed. Selecting this action overrides any group profile preference of which the user may be a member.

Reset to default: This action is only available if preferences have been modified. This

Administrators may want to deny users or groups the ability to modify individual preferences. This is controlled by customizing the user ID or group profile.

Figure 3-39 shows the customization option, which you can access by clicking

Customization-> User profile or Group profile-> Administration.
