3. Enter a host name in the Host field and click Add.
   The new host is added to the host list.

4. Click Apply.

The new host is added and saved to the preferences.

You can add and remove the active subsystems in a host from the Data Source Explorer.

Follow these steps:

1. Right-click on the logical partition (LPAR) in the Data Source Explorer and click Add Subsystem(s)... You can also double-click the logical partition to add a subsystem.

2. Select one or more subsystems from the Subsytem(s) Selection window.

3. Click OK.

The selected subsystem IDs (SSIDs) are added to the host in the Data Source Explorer window.

To remove a subsystem from the logical partition, right-click on a subsystem in the Data Source Explorer and select Remove.

Load Objects

Use the load objects option to fetch DB2 objects (tables, views, and aliases) from the database. The loaded objects are displayed in a hierarchical fashion in the Data Source Explorer. Search for an object by typing the object name in the Type object name field.

Follow these steps:

1. Right-click on a subsystem ID (SSID) in the Data Source Explorer.

2. Click Load Objects.
   A Load Objects dialog appears.

3. Complete the following Object Selection Criteria:

   1. Enter an object name or a creator. You can use the wildcard character % as a part of object or creator name.

      • If you specify creator and leave the object name field as blank, all the objects for the creator appear in the Data Source Explorer.

      • If you specify an object name and leave the creator field blank, all the objects for different creators appear in the Data Source Explorer.

   2. (Optional) Select one or more object types from the Object Types list. By default, all the object types (tables, views, and aliases) are selected.

4. Click OK.

The objects that meet the search criteria are loaded and displayed in the Data Source Explorer.

Open an Object

You can edit multiple objects in different windows simultaneously in both edit and read-only mode. To edit an object, first open it in read-only mode.

Follow these steps:

   • Where Clause

   • Order By

3. Click OK.
   The object data is loaded and displayed in the Data Window in read-only mode as specified.
