Connection list types

The ISPF Export utility supports the following types of connection lists:

• Enterprise connection list (ECL)

  An ECL is a shared list used to identify, using host and port information, the host connections that you define.

  The ECL contains host and port information for one or more UIM servers.

  Important

  • Administration: One or more administrators maintain the ECL. Users with appropriate authority can add, delete and edit ECL connection information .
  • The ECL does not contain Db2 subsystem information. Consequently, the ECL cannot be used as an Export destination. The ECL is more commonly used for IMS connections. From a Db2 perspective, you can use ECL as a seed value to create a PCL or CCL. The PCL and CCL do contain Db2 subsystem information and can be used as Export destinations.

• Personal Connection List (PCL)

  The PCL is a host connection for personal use Separating personal connections from host connections makes it simple to isolate activities in different environments (such as testing systems and production systems or different groups of application systems). The PCL cannot be shared.

• Common Connection List (CCL),

  The CCL is similar to PCL, but can be shared. You can obtain all destinations from your PCL or CCL. To define PCL or ECL, enter the connection information (host name, port and Db2 subsystem ID). If your administrator has set up an ECL, you can create a PCL or CCL from an ECL by adding the Db2 subsystem ID information.
