Configuring ID Pools

When you implement ID management in Management & Control Services (MCS), you create pools of host access IDs. There are several types of pools from which to choose. The type of pool you should select depends on several factors, including how you want to control access to the host and restrictions that the client application might have. For example, to allocate certain IDs to certain users, you assign IDs to user names. To allocate certain IDs to certain computers, you assign IDs to IP addresses or DNS names.

You can change some properties for previously created ID pools, including pool name and lease and inactivity timeout values. The changes you make affect all IDs in the pool, although allocated IDs continue to use previous values until they are released.

To create a new pool
  1. In the MCS left pane under Services, click ID Management.

  2. Under ID Management, click Configure IDs.

  3. In the MCS right pane, in the pool tree, select either All IDs or an existing pool type, right-click to display the shortcut menu, and click New Pool.

    The Pool Creation series of pages guides you through creating a new pool. For detailed information about options on any of these pages, click Help.

  4. In the New Pool page, select a pool type from the drop-down list. For most pool types, type a name for your pool. Pool names cannot contain spaces.
    For this pool type
    Description
    Directory service The pool name can be anything that's meaningful to you.
    IP The name must be the IP address of the client computer.
    DNS For pools based on DNS names, you can specify just the computer name or use the fully qualified DNS name (computer.domain.com). The name you should use depends on the Java Runtime Environment (JRE) in use on the client computer and whether or not domains have been set up.

    In most cases the following should work; however, if using just the computer name returns an error, you should try using the fully qualified domain name, and vice versa.

    In this environment
    Specify
    SUN JRE Just the computer name.
    Microsoft JRE on computers that are members of domains The fully qualified DNS name.
    Microsoft JRE without domains Just the computer name.
    Named You can limit certain IDs to certain users by creating a number of different named pools. For example, you could create a different named pool for each department at your company, for example Accounting.
    User name For User Name pools, do not specify a name on this page. The Pool Name is the User Name you select on the New Name page.
  5. Specify inactivity and lease timeout values. Timeout values apply to all IDs in the pool.
    Note For Terminal Viewer sessions, activity is detected only when data is transmitted. If the IDs in a pool include IDs that will be used by a printer applet, you should set the inactivity timeout to 0 or no value because printer applets typically receive but do not transmit data. Otherwise, the printer applet connection will always be automatically closed after the specified time elapses.

    For more information about timeout values and reclaiming IDs, see the Monitoring Host Access ID Usage topic.

  6. Click Next to add IDs to the pool now, or click Finish to create the pool but not add IDs.

    For all pool types except directory services pools, you can add IDs to the pool later by selecting the pool and choosing New ID from the shortcut menu. For directory services pools, IDs are automatically generated on request from information you supply when configuring the pool.

To rename a pool or change its timeout values
  • Select an existing pool from the tree, right-click to display the shortcut menu, and then click Pool Properties. You cannot rename a pool that contains allocated IDs.

    Renaming a pool is a convenient way to reassign IDs (for example, from one user to another, or one group of computers to another). If you rename a pool in MCS, you may need to make a corresponding change in your client configuration.

To delete a pool
  • Select an existing pool from the tree, right-click to display the shortcut menu, and then click Delete.

    You can delete a pool only if it contains no currently allocated IDs. When you delete a pool, all associated IDs are also deleted.

Note If you change or delete a user name by modifying the directory service, the corresponding change does not automatically occur in the ID pool. To assign IDs to the new user name, you must delete the original user name, and then create a new user name and assign IDs to that user name.
